General

What is chimney pointing and how much does it cost?

Chimney pointing (also called tuckpointing or repointing) is the process of removing deteriorated mortar from between chimney bricks and replacing it with fresh mortar. DME Maintenance charges from $400 for typical section pointing in Suffolk County. All quotes are free and on-site.

General

How do I know if my chimney needs repair?

Common signs your chimney needs repair: white staining (efflorescence) on exterior brick, mortar that is crumbling or missing, water stains near the firebox, rust on the damper, a cracked or missing chimney crown, water in your mechanical room after rain, or visible brick damage from the roofline.

Yes. DME Maintenance cleans dryer vents throughout Suffolk County starting at $149. Dryer vent cleaning can be combined with chimney service in a single visit — mention it when booking. Clogged dryer vents are the #1 cause of home appliance fires in the US.

General

Can a chimney cause carbon monoxide poisoning in my Suffolk County home?

Yes — blocked, cracked, or improperly lined chimneys are one of the most common causes of CO buildup in Suffolk County homes. Annual chimney cleaning and inspection is the primary prevention. If your CO alarm sounds, evacuate immediately, call 911, then call DME Maintenance at 516-690-7471.

General

How much does chimney cleaning cost in Suffolk County?

DME Maintenance charges $165 for a standard gas or oil flue cleaning in Suffolk County. Wood-burning fireplace cleaning starts at $195. Price includes a full safety inspection and written report. Call for an exact quote.

Chimney Cleaning & Sweep —

How often should I have my chimney cleaned?

The NFPA recommends annual chimney inspection and cleaning for all fuel types. Gas flues should be cleaned every 1–2 years. Oil flues annually. Wood-burning fireplaces after every 50–100 fires or at least once per heating season.

Chimney Cleaning & Sweep —

Do I need a chimney cleaning if I only heat with gas?

Yes. Gas chimney cleaning matters because gas combustion produces acidic condensate that deteriorates clay tile liners over time. Annual cleaning and inspection of your gas flue is essential for carbon monoxide safety and to catch liner degradation before it becomes a code issue.

Chimney Cleaning & Sweep —

Is DME Maintenance licensed for chimney cleaning in Suffolk County?

Yes. DME Maintenance holds Suffolk County Consumer Affairs License #H-43223, in perfect standing since 2001. You can verify this directly at the Suffolk County consumer affairs portal.

Chimney Cleaning & Sweep —

What does a chimney cleaning include?

A chimney cleaning includes: brushing and vacuuming the flue, inspection of the liner, crown, cap, damper, and firebox, and a written safety report. For wood fireplaces, creosote is removed to NFPA Level 1 standards. Need a liner upgrade? We assess that during every cleaning.

Chimney Cleaning & Sweep —

Does a gas furnace need chimney cleaning?

Yes. Gas furnaces produce acidic condensate that corrodes clay tile flue liners over time. Annual gas chimney cleaning is the single best way to prevent carbon monoxide from entering your home.

Gas Chimney Cleaning

How often should a gas chimney be cleaned in Suffolk County?

DME Maintenance recommends annual inspection for all gas flues. Cleaning frequency depends on your system — high-efficiency condensing appliances may require more frequent service because they produce more acidic exhaust.

Gas Chimney Cleaning

Can a gas chimney cause carbon monoxide poisoning?

Yes. A cracked, blocked, or deteriorated gas flue liner can allow carbon monoxide to migrate into living spaces. A stainless steel liner upgrade or blockage removal resolves most at-risk conditions. This is documented as a cause of CO poisonings in Long Island homes every year.

Gas Chimney Cleaning

How often does an oil burner chimney need to be cleaned?

Annually, without exception. Oil chimney cleaning is critical — skipping even one year can allow soot to restrict draft enough to cause puffbacks, equipment failure, and carbon monoxide risk.

Oil Chimney Cleaning

What is a puffback and how do I prevent it?

A puffback happens when unburned oil vapors ignite explosively in the furnace or boiler. Annual chimney cleaning and burner service prevents puffbacks.

Oil Chimney Cleaning

If I switch from oil to gas, do I need a new chimney liner?

Yes. Oil-to-gas conversions require a stainless steel chimney liner under Suffolk County code and most appliance manufacturer requirements. Call DME Maintenance at 516-690-7471 for a free liner assessment.

Oil Chimney Cleaning

How often should a wood-burning fireplace be swept?

The NFPA recommends annual wood fireplace chimney cleaning, or after every 50–100 fires — whichever comes first. Suffolk County's heating season typically means annual service before fall.

Wood Fireplace Chimney Cleaning

What is creosote and why is it dangerous?

Creosote is a tar-like residue produced by incomplete wood combustion. It builds up inside chimney flues and is highly flammable. A thick layer can ignite into a chimney fire burning above 2,000°F — cracking flue liners and potentially igniting your home's structure.

Wood Fireplace Chimney Cleaning

Can I use my fireplace before getting it cleaned?

DME Maintenance recommends inspection before first use each season. If the chimney was not cleaned last spring and has not been inspected, call for an inspection first. A blocked or creosote-laden chimney can cause CO to back up. Chimney cap condition should also be verified before lighting the first fire.

Wood Fireplace Chimney Cleaning

Do gas fireplaces need annual cleaning?

Yes. Gas fireplaces should be cleaned and inspected annually. Burner ports clog, pilot assemblies drift, and venting connections can loosen — all of which affect safety and performance.

Gas Fireplace Cleaning

What does a gas fireplace cleaning include?

DME Maintenance's gas fireplace service includes: burner cleaning, pilot service, venting inspection, glass cleaning, firebox cleaning, and a carbon monoxide safety check. Call to schedule.

Gas Fireplace Cleaning

How often does a wood stove need cleaning?

Annually at minimum. If your wood stove is a primary heat source running most of the winter, mid-season cleaning is also recommended. Connector pipes on wood stoves accumulate creosote faster than open fireplace flues.

Wood Stove Cleaning

What is included in a wood stove cleaning?

DME Maintenance's wood stove service covers: stove interior and baffle, connector pipe, full flue liner, cap and spark arrestor, and gasket/seal inspection. Call to schedule.

Wood Stove Cleaning

How often does a pellet stove need professional cleaning?

Annually, plus homeowner ash pan cleaning weekly during the burn season. The annual professional service covers the full combustion chamber, heat exchanger, exhaust vent, and mechanical components that homeowners cannot safely access.

Pellet Stove Cleaning

Why does my pellet stove keep shutting off?

Most pellet stove shutdowns are caused by a clogged exhaust vent or dirty combustion sensor. Professional cleaning resolves the majority of shutdown issues without parts replacement.

Pellet Stove Cleaning

What causes chimney blockages in Suffolk County?

The most common causes are bird nests, squirrel and raccoon nests, fallen mortar or brick pieces, and damaged or missing chimney caps that allow debris to accumulate.

Chimney Blockage Removal

Is a blocked chimney dangerous?

Extremely. A fully blocked flue prevents combustion gases — including carbon monoxide — from venting. Do not use your heating system if you suspect a blockage. Call DME Maintenance at 516-690-7471 for same-week service.

Chimney Blockage Removal

How do I prevent chimney blockages?

A properly fitted stainless steel chimney cap with mesh sides is the most effective prevention. DME Maintenance installs caps starting at $255. Pair with an annual chimney cleaning to catch early buildup.

Chimney Blockage Removal

How much does chimney repair cost in Suffolk County?

Chimney pointing runs $400–$900 for typical sections. Crown repair starts at $395. Flashing repair varies by scope. DME Maintenance provides free on-site estimates — call 516-690-7471.

Chimney Repair

How do I know if my chimney needs repair?

Common signs: white staining (efflorescence) on exterior brick, crumbling mortar, water stains near the firebox, rust on the damper, a cracked or missing chimney crown, or water in your mechanical room after rain.

Chimney Repair

What happens if I ignore chimney repairs?

Water damage is progressive. What starts as cracked mortar becomes loose brick, then structural damage and water in your walls. A $400 pointing job ignored for two seasons can become a $4,000 structural repair.

Chimney Repair

How much does a chimney cap cost in Suffolk County?

DME Maintenance installs standard stainless steel chimney caps starting at $255 in Suffolk County. Multi-flue caps and custom sizes are priced separately — call 516-690-7471.

Chimney Cap Replacement

Does every chimney need a cap?

Yes. An uncapped chimney allows rain, snow, birds, and animals directly into your flue. Water in a chimney liner accelerates deterioration dramatically. A cap is the most cost-effective chimney protection available.

Chimney Cap Replacement

How long does a chimney cap last?

A stainless steel chimney cap properly installed lasts 20+ years in Suffolk County's coastal environment. DME Maintenance only installs stainless — never galvanized, which rusts in 5–10 years near the coast. Pair with chimney waterproofing for full protection.

Chimney Cap Replacement

What is a chimney crown and what does it do?

The chimney crown is the concrete slab at the top of your chimney that seals the brick from rain. A properly built crown with an overhang directs water away from the masonry. Pair crown repair with a chimney cap and waterproofing for complete top protection.

Chimney Crown Repair

How much does chimney crown repair cost in Suffolk County?

DME Maintenance charges from $395 for chimney crown repair in Suffolk County. Severely deteriorated crowns require demolition and rebuild, quoted on-site after inspection.

Chimney Crown Repair

Can I repair a chimney crown myself?

Homeowners sometimes apply crown sealant products, but improper application on a structurally cracked crown fails within one freeze-thaw cycle. DME Maintenance uses commercial-grade materials with proper surface prep. After repair, ChimSaver waterproofing extends the life of the repair significantly.

Chimney Crown Repair

What is a chimney chase cover?

A chase cover is a flat metal cover that fits over the top of a prefab chimney chase — the box-like structure that surrounds the metal flue pipe on factory-built fireplaces. It prevents rain from entering the chase.

Chimney Chase Cover

How do I know if my chase cover has failed?

Signs of a failed chase cover include: rust stains running down the chase exterior, water stains on the ceiling or walls near the fireplace, and a rusted or collapsed metal cover visible from the roofline.

Chimney Chase Cover

How much does chimney pointing cost in Suffolk County?

DME Maintenance charges from $400 for chimney pointing in Suffolk County. Full chimney pointing for heavily deteriorated chimneys typically runs $600–$900+. All quotes are free and on-site — call 516-690-7471.

Chimney Pointing

What is the difference between pointing and tuckpointing?

Tuckpointing and pointing (repointing) are the same thing — removing deteriorated mortar and replacing it with fresh mortar. After pointing, DME Maintenance recommends ChimSaver waterproofing to protect the fresh mortar immediately.

Chimney Pointing

How long does chimney pointing last?

Properly done chimney pointing lasts 25–30 years under typical Suffolk County conditions. Following pointing with ChimSaver waterproofing treatment extends the life of the repair by protecting fresh mortar from moisture exposure.

Chimney Pointing

What is ChimSaver chimney waterproofing?

ChimSaver is a professional penetrating chimney waterproofing treatment. Unlike paint or silicone sealants, ChimSaver is vapor-permeable — blocks water from outside while allowing moisture vapor from inside to escape. Best applied after chimney pointing or crown repair.

Chimney Waterproofing

When should chimney waterproofing be applied?

ChimSaver should be applied after any chimney repairpointing, crown work, or cap installation — on clean, dry masonry. In Suffolk County, fall or spring are ideal application windows.

Chimney Waterproofing

Will waterproofing stop a leaking chimney?

Waterproofing alone does not fix a chimney leaking through structural failures — those must be repaired first with pointing, crown repair, or flashing work. ChimSaver then protects the repaired masonry from future water penetration.

Chimney Waterproofing

How long does a prefab fireplace last?

Factory-built prefab fireplaces typically last 20–30 years with proper maintenance. Key failure points are the chase cover (5–10 years for galvanized), firebox panels (15–25 years), and the metal flue system (20–30 years).

Prefab Chimney Service

Can a prefab chimney be repaired or does it need to be replaced?

It depends on which components have failed. Chase covers and individual firebox panels are replaceable. If the firebox itself or the metal flue is structurally compromised, replacement is usually more cost-effective than repair. DME Maintenance gives honest guidance.

Prefab Chimney Service

How much does chimney liner installation cost in Suffolk County?

DME Maintenance installs stainless steel chimney liners starting at $1,670 in Suffolk County. Final cost depends on flue height, required liner diameter, and whether insulation wrap is required. Call for a free assessment.

Chimney Liner Upgrade

Do I need a new chimney liner when converting from oil to gas in Suffolk County?

Yes. Oil-to-gas conversions require a stainless steel chimney liner under Suffolk County code. The original oil flue is typically oversized for gas venting and contains oil residue that deteriorates with gas combustion. A properly sized stainless liner is required before the new appliance can be put into service.

Chimney Liner Upgrade

How do I know if my chimney liner needs to be replaced?

Signs include: home over 25 years old with no liner inspection, replacing your furnace or boiler, carbon monoxide detector alerts, white staining (efflorescence) on chimney brick, or a video inspection revealing cracks. Schedule an annual chimney cleaning and we assess liner condition during every visit.

Chimney Liner Upgrade

What brands of chimney liner does DME Maintenance install?

DME Maintenance is factory-authorized for stainless steel chimney liner installation. We install flexible, rectangular, oval, and insulated liner systems — all with a lifetime warranty.

Chimney Liner Upgrade

Is a chimney liner required by Suffolk County code?

Yes, in most circumstances. Suffolk County municipalities require a properly sized, code-compliant liner for all gas and oil appliances. Liner installation by DME Maintenance meets all Suffolk County requirements under License #H-43223. After installation, we recommend an annual chimney cleaning to maintain liner performance.

Chimney Liner Upgrade

How much does a chimney inspection cost in Suffolk County?

DME Maintenance includes a full inspection with every chimney cleaning at no extra charge. A standalone inspection is quoted on-site — call 516-690-7471. Level 2 camera inspection for home sales or after a chimney fire is priced separately.

Chimney Inspection

What is the difference between a Level 1 and Level 2 chimney inspection?

A Level 1 inspection is a visual examination of all accessible components — the standard annual inspection. A Level 2 inspection includes video camera scanning of the full flue interior and is required when selling a home, after a chimney fire, or when changing fuel types. DME Maintenance performs both in Suffolk County.

Chimney Inspection

How often should I have my chimney inspected in Suffolk County?

The NFPA recommends annual chimney inspection for every fuel type — gas, oil, and wood. Suffolk County's coastal environment and freeze-thaw cycles make annual inspection especially important. Many homeowners book inspection and cleaning together in the fall before heating season.

Chimney Inspection

Do I need a chimney inspection if I never use my fireplace?

Yes. Even unused chimneys are exposed to weather year-round. A missing or damaged cap, cracked chimney crown, or failed flashing can allow water damage whether the fireplace is used or not. Annual inspection catches these early.

Chimney Inspection

What does DME Maintenance look for during a chimney inspection?

Our 21-point inspection covers: chimney cap, crown, flashing, exterior masonry and mortar joints, damper, firebox, smoke chamber, and flue liner condition. You receive a written report with photos and honest repair recommendations — no pressure.

Chimney Inspection

Do I need a chimney inspection when buying a house in Suffolk County?

Yes, in most cases. Mortgage lenders frequently require a Level 2 chimney inspection when a home has a fireplace or chimney. Even when not required, a chimney inspection protects buyers from inheriting expensive problems — a liner replacement or structural repair discovered after closing is entirely the buyer's cost.

Chimney Inspection Before Buying a House

What is a Level 2 chimney inspection and when is it required?

A Level 2 inspection includes a full visual examination plus video camera scanning of the flue interior. It is required by the NFPA when selling a home, after a chimney fire, or when changing fuel types. Most Suffolk County mortgage lenders accept DME Maintenance's written Level 2 report for underwriting purposes.

Chimney Inspection Before Buying a House

How quickly can DME Maintenance schedule a chimney inspection for a real estate closing?

DME Maintenance typically schedules Suffolk County inspections within the same week. For urgent closing timelines, call 516-690-7471 directly — we accommodate rush inspections when our schedule permits. Written report with photos is delivered the same day as the inspection.

Chimney Inspection Before Buying a House

What happens if the chimney inspection finds a problem before closing?

DME Maintenance provides a written repair estimate alongside the inspection report. This gives buyers and sellers documentation for price negotiation or seller concessions. Common findings include liner replacement, crown repair, and chimney pointing — all of which DME Maintenance can repair immediately after closing.

Chimney Inspection Before Buying a House

Can DME Maintenance provide documentation for a real estate attorney or lender?

Yes. Our inspection report includes technician name, license number (#H-43223), inspection date, photo documentation, findings, and repair recommendations in a format suitable for real estate attorney review and mortgage lender submission.

Chimney Inspection Before Buying a House

What counts as a chimney emergency in Suffolk County?

Call DME Maintenance immediately if: your carbon monoxide detector has alarmed, you can smell combustion gases inside your home with the heating system running, your boiler or furnace has shut down and you suspect a flue blockage, a storm has displaced chimney components, or you had a puffback. Do not restart the appliance until the flue is inspected and cleared.

Emergency Chimney Service

How quickly can DME Maintenance respond to a chimney emergency in Suffolk County?

DME Maintenance responds to Suffolk County emergency chimney calls on a priority basis — same-week in most cases, often same-day for active carbon monoxide or no-heat situations. Call directly for the fastest response.

Emergency Chimney Service

What should I do if my carbon monoxide alarm goes off and I have a chimney?

Immediately: evacuate the home, call 911, then call DME Maintenance at 516-690-7471. Do not re-enter until emergency services have cleared the home. A blocked or cracked flue is one of the leading causes of CO poisoning in Suffolk County homes. DME Maintenance will inspect and clear the blocked flue and assess liner condition before the appliance is restarted.

Emergency Chimney Service

My furnace shut down — could it be a chimney problem?

Yes. Modern furnaces and boilers have safety sensors that shut the unit down when flue pressure is abnormal — which happens when the flue is blocked or restricted. A chimney blockage, collapsed liner section, or frozen condensate line can all trigger a shutdown. Call DME Maintenance at 516-690-7471 before calling your HVAC technician — the fix may be a chimney issue, not an equipment issue.

Emergency Chimney Service

Does a storm-damaged chimney need emergency service?

If a chimney cap has blown off, masonry has been displaced, or the chimney crown is visibly cracked after a storm — yes, call DME Maintenance before using the appliance. Rain entering an uncapped flue, or debris from a damaged crown falling into the firebox, can create blockages that back combustion gases into the home.

Emergency Chimney Service

How much does chimney damper repair or replacement cost in Suffolk County?

DME Maintenance installs top-sealing dampers starting at $999 in Suffolk County. Throat damper repair is quoted on-site after inspection — call 516-690-7471. Top-sealing dampers are almost always the better long-term value: they seal tighter, last longer, and solve the summer odor and winter draft problem simultaneously.

Chimney Damper Repair & Replacement

What is the difference between a throat damper and a top-sealing damper?

A throat damper is the traditional cast-iron plate inside your firebox, just above the fire. A top-sealing damper installs at the very top of the flue and uses a rubber gasket to seal the chimney from above. Top-sealing dampers provide a far tighter seal, prevent animal entry, and eliminate summer odors — something a throat damper cannot do.

Chimney Damper Repair & Replacement

Why is cold air coming down my chimney even when the damper is closed?

A throat damper that appears closed rarely seals fully — the cast iron warps from years of heat exposure and leaves gaps. Cold air falls through these gaps continuously. A top-sealing damper eliminates this entirely by sealing the flue at the top with a rubber gasket rated for tight closure.

Chimney Damper Repair & Replacement

My fireplace smells like smoke in summer — is the damper the problem?

Usually yes. In summer, air-conditioned homes create negative pressure that draws air down the flue — pulling creosote and moisture odors with it. A failed or partially open throat damper has no defense against this. A top-sealing damper stops it completely, and an annual chimney cleaning removes the creosote that causes the odor.

Chimney Damper Repair & Replacement

Can I replace a chimney damper myself?

Throat damper replacement requires working inside a firebox and fitting a specific throat size — mistakes create a permanent draft problem. Top-sealing damper installation requires roof access and proper fit to your flue tile. DME Maintenance installs both types in Suffolk County — most jobs completed in under two hours. Call .

Chimney Damper Repair & Replacement

How much does dryer vent cleaning cost in Suffolk County?

DME Maintenance charges from $149 for dryer vent cleaning in Suffolk County. Combining dryer vent cleaning with your annual chimney cleaning saves a separate service call — call 516-690-7471 to schedule both in one visit.

Dryer Vent Cleaning

How often should dryer vents be cleaned?

The NFPA and most appliance manufacturers recommend annual dryer vent cleaning. If you do multiple loads per day, have a longer vent run (common in Suffolk County split-levels and colonials), or notice longer drying times — clean more frequently.

Dryer Vent Cleaning

What are the signs that my dryer vent is clogged?

Key signs: clothes take two cycles to dry fully, the dryer exterior feels very hot after a cycle, the laundry room feels humid after drying, you notice a burning smell, or the exterior vent flap doesn't open during drying. Any one of these warrants immediate cleaning.

Dryer Vent Cleaning

Is a clogged dryer vent actually dangerous?

Yes. The U.S. Fire Administration identifies clogged dryer vents as the leading cause of home appliance fires — approximately 2,900 fires per year nationally. Lint is highly flammable and accumulates in the duct with every load. Annual cleaning is the only effective prevention.

Dryer Vent Cleaning

Can DME Maintenance clean my dryer vent at the same time as my chimney?

Yes — and this is the most efficient way to book both services. We're already at your home with the equipment. Dryer vent cleaning typically adds under an hour to a chimney service visit. Call or mention dryer vent when booking your chimney cleaning.

Dryer Vent Cleaning

What is chimney flashing and why does it leak?

Chimney flashing is the metal system sealing the joint between your chimney and roof. It consists of step flashing along the chimney sides and counter flashing embedded into the chimney mortar joints. It leaks when mortar cracks release the counter flashing, step flashing corrodes, or previous caulk repairs dry out and crack — typically within 1–3 years.

Chimney Flashing Repair

How do I know if my roof leak is actually a chimney flashing problem?

If water staining appears on your ceiling or walls near the chimney base — especially during rain but not snow melt — the leak source is almost always chimney flashing, not the roof shingles. DME Maintenance provides free on-site diagnosis to confirm the exact source before any repair work begins. Call .

Chimney Flashing Repair

How much does chimney flashing repair cost in Suffolk County?

Chimney flashing repair cost varies significantly by the extent of failure and whether counter flashing re-embedding, step flashing replacement, or saddle/cricket work is needed. DME Maintenance provides free on-site estimates with written scope and photos — no obligation. Call to schedule.

Chimney Flashing Repair

Can I fix chimney flashing myself with caulk or roofing cement?

Caulk and roofing cement are temporary measures that typically last 1–3 seasons before drying and cracking. They do not address the root cause — usually counter flashing that has pulled free from the chimney mortar joint. DME Maintenance re-embeds counter flashing into fresh mortar for a permanent repair.

Chimney Flashing Repair

Should chimney flashing repair be combined with other work?

Often yes. Flashing failures usually accompany deteriorated mortar joints — the same moisture that compromised the flashing has worked into the masonry. DME Maintenance assesses the full chimney during every flashing repair and recommends combining with ChimSaver waterproofing to protect the repaired surfaces.

Chimney Flashing Repair

Can a chimney really cause carbon monoxide poisoning?

Yes — and it is one of the most common causes. A blocked, cracked, or improperly lined chimney prevents combustion gases from venting outside. CO then migrates into living spaces. Suffolk County homes with aging clay tile liners and recent gas conversions are at elevated risk. Annual chimney inspection is the primary prevention.

Carbon Monoxide Safety & Your Chimney —

What should I do if my carbon monoxide alarm goes off?

Immediately: (1) Evacuate everyone from the home — do not stop for belongings. (2) Call 911 from outside or a neighbor's home. (3) Do not re-enter until emergency services have cleared the home. (4) Call DME Maintenance at 516-690-7471 — we inspect and clear the chimney and assess liner condition before your heating system is restarted.

Carbon Monoxide Safety & Your Chimney —

How often should I test my CO detectors in Suffolk County?

Test CO detectors monthly using the test button. Replace batteries annually. Replace the unit itself every 5–7 years — CO sensors degrade over time and older units may not alarm at dangerous levels. Place detectors on every level of your home and outside every sleeping area.

Carbon Monoxide Safety & Your Chimney —

My furnace is new — does my chimney still need inspection for CO safety?

Yes — and especially so. New high-efficiency furnaces produce cooler, more acidic exhaust gases that deteriorate old clay tile liners faster than older equipment. A gas chimney inspection after any appliance replacement is essential. Most appliance manufacturers and Suffolk County municipalities require a stainless steel liner when installing new equipment.

Carbon Monoxide Safety & Your Chimney —

What chimney conditions most commonly cause CO problems in Suffolk County homes?

The five most common causes: (1) Bird or animal nest blockage in the flue. (2) Cracked or collapsed clay tile liner sections. (3) Improperly sized flue for the appliance — common after oil-to-gas conversions. (4) Disconnected or damaged flue connector pipe. (5) Frozen condensate in high-efficiency appliance vents during extreme cold. All are preventable with annual chimney cleaning and inspection.

Carbon Monoxide Safety & Your Chimney —

Why is smoke coming into my house from the chimney?

The most common causes are a blocked flue, a stuck damper, negative air pressure, or a cold flue. Stop using the appliance and call DME Maintenance at 516-690-7471 for a same-week diagnosis.

Smoke Coming Into House —

Is smoke coming into the house dangerous?

Yes. Smoke contains carbon monoxide. If smoke is entering your living space, stop using the appliance immediately. If your CO detector has alarmed, evacuate and call 911.

Smoke Coming Into House —

What is chimney backdraft?

Backdraft occurs when air pressure causes flue gases to flow down instead of up. Common triggers include exhaust fans, new insulation, or a cold flue. A top-sealing damper and proper flue sizing prevent most backdraft.

Smoke Coming Into House —

Why does smoke come back into my house from the fireplace?

The most common causes are a blocked flue (birds, debris, creosote), a stuck or missing damper, negative air pressure in the house, a cold flue that hasn't been primed, or a poorly designed fireplace opening that's too large for the flue. DME Maintenance diagnoses the specific cause rather than guessing.

Smoke Coming Into House —

What is negative pressure and how does it cause smoke problems?

Modern tight construction — sealed windows, exhaust fans, energy improvements — can create negative air pressure inside the house. The house tries to pull replacement air from wherever it can, including down the chimney flue. Solutions include cracking a window near the fireplace, installing an air inlet, or upgrading to a sealed combustion insert.

Smoke Coming Into House —

Can I use the fireplace while waiting for repairs?

If smoke is entering the living space, do not use the fireplace until the cause has been diagnosed and corrected. Combustion gases including carbon monoxide can accompany smoke. Call DME Maintenance at 516-690-7471 for a diagnosis before the next fire.

Smoke Coming Into House —

Why does my chimney smell in summer when I'm not using it?

Air-conditioned homes create negative pressure that draws air down the chimney — pulling creosote odors into the living space. A top-sealing damper stops this. Annual chimney cleaning removes the creosote causing the odor.

Chimney Smell in House —

What does a creosote smell in the house mean?

Creosote odor means deposits inside the flue are being activated by heat and humidity. Annual cleaning removes the source.

Chimney Smell in House —

My fireplace smells musty — is that a chimney problem?

A musty smell usually means moisture in the flue from a cracked crown, missing cap, or failed flashing. Have the crown, cap, and flashing inspected.

Chimney Smell in House —

Why does my fireplace smell in summer even when I haven't used it?

Summer chimney odors are almost always one of two things: creosote activated by heat and humidity coming down an open damper, or animal debris in the flue. A top-sealing damper eliminates the open flue path that allows outside air — and odors — to enter. Annual cleaning removes the creosote source.

Chimney Smell in House —

Why does my chimney smell like a campfire?

Campfire or wood-smoke smell from an unused fireplace means creosote deposits in the flue are off-gassing as temperatures rise. Annual cleaning removes Stage 1 and Stage 2 creosote before it becomes a persistent odor problem. A top-sealing damper prevents the chimney from acting as an intake during warm months.

Chimney Smell in House —

Is chimney smell a safety hazard?

Creosote odor is unpleasant but not immediately dangerous when the fireplace isn't in use. Animal debris and nesting material in the flue creates both odor and a blockage risk — and should be removed before using the fireplace. Call DME Maintenance at 516-690-7471 to identify the source.

Chimney Smell in House —

Why is water getting into my chimney?

The five most common entry points: a missing cap, cracked crown, failed flashing, deteriorated mortar joints, or a cracked flue liner. Proper diagnosis requires checking all five.

Chimney Leaking Water

There's water in my firebox after rain — what's the source?

Water inside the firebox after rain usually means a missing cap or cracked crown. Call for free on-site diagnosis.

Chimney Leaking Water

I have ceiling stains near my chimney — is it roof or chimney?

If staining appears near the chimney after rain with intact shingles, the source is almost always flashing failure at the roof-chimney joint.

Chimney Leaking Water

Should I waterproof my chimney after repair?

Yes — ChimSaver waterproofing applied after crown repair, pointing, or flashing work seals all repaired surfaces permanently.

Chimney Leaking Water

My ceiling is stained near the chimney — is that a chimney leak?

Possibly, but not certainly. Ceiling stains near a chimney can come from flashing failure (most common), a cracked crown, a missing or damaged cap, failing mortar joints, or an unrelated roof leak. DME Maintenance systematically inspects all potential entry points before recommending repairs — we find the actual source rather than guessing.

Chimney Leaking Water

Water is getting into my firebox — where is it coming from?

Water in the firebox almost always comes from a failed or missing chimney cap, a cracked crown, or severely deteriorated mortar joints at the top of the chimney. Less commonly it comes from flashing failure. Call DME Maintenance at 516-690-7471 for an on-site diagnosis.

Book in August or September. By October appointments are limited. By November you may wait 2-3 weeks.

Fall Chimney Cleaning

Do I need a chimney cleaning every fall?

The NFPA recommends annual inspection and cleaning for every fuel type. For oil systems, annual cleaning is mandatory.

Fall Chimney Cleaning

What does a fall chimney cleaning include?

Full flue sweep, creosote removal, draft and CO testing, 21-point inspection, before/after photos, and written safety report emailed same day.

Fall Chimney Cleaning

When is the best time to schedule fall chimney cleaning in Suffolk County?

September and early October. Scheduling in September means you beat the rush — November and December bookings fill up quickly as homeowners scramble before the first cold snap. Early scheduling also gives time to address any issues found before heating season starts.

Fall Chimney Cleaning

What happens during a fall chimney cleaning?

DME Maintenance performs a complete Level 1 inspection — cap, crown, flashing, mortar joints, damper, firebox, smoke chamber, and liner — plus a full cleaning of the flue. You receive a written report documenting the chimney condition. If anything needs attention before winter, you have time to address it.

How much does chimney liner installation cost in Suffolk County?

Stainless steel liner installation starts at $1,670. Final cost depends on flue length, diameter, insulation, and permit fees. Written estimate after on-site measurement.

Chimney Service Cost Guide

How much does chimney crown repair cost?

Crown repair starts at $395. DME Maintenance recommends combining with ChimSaver waterproofing in a single visit.

Chimney Service Cost Guide

Why do chimney service prices vary?

Chimney condition is the main variable. A cap on a clean chimney is straightforward. The same job on a chimney with a deteriorated crown and partial blockage requires additional work first.

Chimney Service Cost Guide

Do you charge for estimates?

Estimates for repair work are free and provided on-site after a visual inspection. There is no charge to come out and assess a repair situation. Standalone inspection-only visits (without cleaning) are quoted when you call — pricing depends on the inspection level required.

Chimney Service Cost Guide

Why won't you give me a price over the phone?

Chimney repair pricing varies significantly based on chimney height, access, extent of damage, and what we find on inspection. An honest repair estimate requires seeing the chimney. Phone quotes without inspection are either wildly inaccurate or deliberately low to get in the door. DME Maintenance provides written, itemized estimates on-site — before any work begins.

How much does power washing cost in Suffolk County?

DME Maintenance charges flat rates: driveways from $350, walkways from $175, decks and patios from $350, house siding (1-story) from $450, house siding (2-story) from $650. A full exterior package — siding, driveway, walkways, and patio in one visit — starts at $895. Free on-site estimate. Call .

Power Washing

What is the difference between power washing and pressure washing?

Power washing uses heated water, which is significantly more effective at dissolving grease, oil, mold, and organic buildup than cold-water pressure washing. DME Maintenance uses hot-water power washing equipment for all residential jobs in Suffolk County — the results are noticeably better on Long Island driveways and siding that accumulate salt, mold, and algae.

Power Washing

Is power washing safe for my deck and siding?

Yes — when done by a professional using the correct pressure settings and nozzles for each surface. DME Maintenance uses lower pressure for wood decks, composite decking, and vinyl siding, and higher pressure for concrete driveways and sidewalks. We pre-inspect every surface and protect landscaping, outlets, and windows before starting.

Power Washing

How often should I power wash my Suffolk County home?

Most Suffolk County homes benefit from power washing every 1–2 years. South Shore homes near the water — where salt air accelerates mold, algae, and staining — may need annual cleaning. Driveways and patios benefit from cleaning every 12–18 months depending on tree cover and traffic.

Power Washing

Can you remove oil stains from my driveway?

Yes. Oil and grease stains require pre-treatment with a degreasing solution before power washing. DME Maintenance applies surface-appropriate pre-treatments for oil stains, mold, algae, and rust before washing. Results depend on how long the stain has been set and the driveway material — concrete responds better than asphalt.

Power Washing

Do you power wash throughout Suffolk County?

Yes — DME Maintenance provides power washing throughout all of Suffolk County including the South Shore, North Shore, Five Towns, and all mid-Suffolk communities. Same-week appointments available. Suffolk County License #H-43223. Call .

Power Washing

Do you offer a full exterior power washing package?

Yes. The full exterior package covers house siding, driveway, walkways, and patio in one visit — starting at $895 for most Suffolk County single-family homes. Bundling is more cost-effective than scheduling each surface separately. Free on-site estimate — call 516-690-7471.

Power Washing

Is a new chimney liner required when converting from oil to gas in Suffolk County?

Yes. Suffolk County code and appliance manufacturer requirements both mandate a properly sized stainless steel liner before a new gas appliance can be put into service. Your existing oil flue is oversized for gas venting and contains oil residue that deteriorates with gas combustion. DME Maintenance handles the liner installation and provides full documentation for your permit file. Suffolk License #H-43223. Call .

Oil-to-Gas Chimney Conversion

How much does a chimney liner cost for an oil-to-gas conversion in Suffolk County?

DME Maintenance installs stainless steel chimney liners for oil-to-gas conversions starting at $1,670 in Suffolk County. Final cost depends on flue height, required liner diameter (typically 4", 5", or 6" for residential gas applications), and whether insulation wrap is required. Free on-site estimate — call 516-690-7471.

Oil-to-Gas Chimney Conversion

When do I need to schedule the chimney liner installation?

Schedule the liner installation before your gas company completes the conversion, not after. If the liner is in place when National Grid or your plumber arrives, everything is ready and the conversion proceeds without delay. If you wait until after, you may be without heat while coordinating the liner installation. DME Maintenance typically schedules within the same week as your call — 516-690-7471.

Oil-to-Gas Chimney Conversion

What size chimney liner is required for a gas boiler or furnace?

Liner diameter is determined by your new appliance's BTU output and the length of the flue. Most residential gas boilers and furnaces in Suffolk County require a 4", 5", or 6" diameter stainless liner. DME Maintenance measures on-site and sizes the liner precisely to your appliance specification — no guesswork, full documentation provided.

Oil-to-Gas Chimney Conversion

Does DME Maintenance work with my plumber and gas company?

Yes. DME Maintenance coordinates regularly with plumbers and gas utilities throughout Suffolk County on oil-to-gas conversions. We provide the liner installation documentation your plumber needs for the permit file and that National Grid or PSE&G requires before completing the conversion. Call to schedule.

Oil-to-Gas Chimney Conversion

What happens if I use my old clay liner with the new gas appliance?

The new gas appliance will produce cooler exhaust that condenses inside the oversized clay flue. That acidic condensate deteriorates the clay tile and mortar joints, eventually cracking the liner. A cracked liner is a carbon monoxide pathway into the home. It also voids the appliance manufacturer's warranty and will fail Suffolk County inspection. A properly sized stainless steel liner eliminates all of these risks.

Oil-to-Gas Chimney Conversion

Does the liner come with a warranty?

Yes. DME Maintenance is a factory-authorized stainless steel chimney liner installer — every liner comes with a lifetime warranty. Installation is documented with liner specifications, install date, and manufacturer warranty information for your records.

Oil-to-Gas Chimney Conversion

How much does a chimney rebuild cost in Suffolk County?

DME Maintenance prices chimney rebuilds based on scope after on-site inspection. Partial above-roofline rebuilds (upper courses only) typically run $1,200–$2,500. Full above-roofline rebuilds start around $3,500. Complete chimney reconstruction from foundation to cap starts around $6,000–$8,000 depending on height, materials, and liner requirements. Free on-site estimate — call 516-690-7471.

Chimney Rebuild

What is the difference between chimney pointing and chimney rebuild?

Chimney pointing removes deteriorated mortar and replaces it with fresh mortar — the brick itself remains. A chimney rebuild removes and replaces the actual brick and block structure, not just the mortar. Pointing is appropriate when mortar joints are failing but bricks are intact. A rebuild is necessary when bricks are spalling, the structure is leaning, or the damage is too extensive for mortar repair alone.

Chimney Rebuild

What signs indicate a chimney needs to be rebuilt rather than repaired?

Signs that a rebuild may be necessary include: visible leaning or bowing of the chimney stack, large sections of spalling brick (face of brick falling away), multiple failed mortar courses that can't be stabilized with pointing, interior structural failure visible on inspection, previous chimney fire that damaged the liner and masonry, and chimneys that have settled significantly with the house. DME Maintenance assesses on-site and recommends only what's necessary — we'll tell you if pointing will do the job.

Chimney Rebuild

Can you match my existing brick for the rebuild?

We make every effort to source brick that matches your existing home exterior as closely as possible. Exact matches are sometimes difficult with older brick, but DME Maintenance works with Suffolk County masonry suppliers to find the closest available match. If an exact match isn't possible, we discuss the options with you before work begins.

Chimney Rebuild

Does a chimney rebuild include a new liner?

For full rebuilds, yes — a new stainless steel chimney liner is installed as part of the reconstruction. For partial above-roofline rebuilds, the existing liner is inspected and replaced if damaged or if the appliance type has changed. Every rebuild includes a new chimney crown and cap.

Chimney Rebuild

How long does a chimney rebuild take?

A partial above-roofline rebuild typically takes one to two days. A full stack rebuild is typically two to three days. Complete chimney reconstruction from foundation to cap may take three to five days depending on height and complexity. DME Maintenance schedules rebuilds with same-week start dates in most cases.

Chimney Rebuild

Do you offer chimney rebuild in all Suffolk County towns?

Yes — DME Maintenance performs chimney rebuilds throughout all of Suffolk County, including the South Shore, North Shore, Five Towns, and all mid-Suffolk communities. Suffolk County Home Improvement License #H-43223. Free on-site estimate — call 516-690-7471.

How do I know if an animal is in my chimney?

Common signs: scratching or chittering sounds from the fireplace or heating system area, chirping or bird sounds from inside the flue, strong odor (especially with deceased animal), visible nesting material falling into the firebox, or a live animal appearing in your basement or living space. If you hear sounds, do not light a fire — call DME Maintenance at 516-690-7471 for same-day assessment.

Animals in Chimney

What animals commonly get into Suffolk County chimneys?

The most common in Suffolk County are raccoons (especially females denning in late winter/spring), gray squirrels (frequently fall down furnace flues), starlings and chimney swifts (nest in flue tiles — their nests are a fire and CO hazard), and bats (summer roosting). All of these situations require the same permanent solution: a properly fitted stainless steel chimney cap with animal-guard mesh.

Animals in Chimney

Is it safe to use my chimney if there are animals or a nest inside?

No. Do not run your heating system or light a fireplace if you suspect animal occupancy or a nest in the flue. A compressed bird nest can partially or fully block the flue, causing combustion gases — including carbon monoxide — to back up into the home. Call DME Maintenance at 516-690-7471 before using the appliance.

Animals in Chimney

Can DME Maintenance remove the animal and install a cap in the same visit?

In most cases yes. For squirrels and birds, DME Maintenance removes nesting material, clears the flue, and installs the stainless steel cap same day. Raccoons with young may require a waiting period. Bats should not be excluded during their active season (May–August) to avoid trapping young inside — cap installation is typically scheduled for September or later for bat situations.

Animals in Chimney

What type of chimney cap prevents animals from re-entering?

A heavy-gauge stainless steel chimney cap with welded animal-guard mesh around the sides. Standard spark-arrestor screen is not sufficient for raccoons, which can push through lightweight mesh. DME Maintenance installs commercial-grade stainless caps with animal-guard mesh rated to resist raccoon entry — same cap installed as a preventive measure costs the same as one installed after an intrusion.

Animals in Chimney

How much does it cost to fix an animal-in-chimney problem in Suffolk County?

A stainless steel chimney cap with animal-guard mesh starts at $255 installed through DME Maintenance in Suffolk County. If nesting material needs to be removed before the cap is installed, that is quoted on-site. A full flue inspection after animal occupancy — recommended to check for damage — starts at $165. Call for a free on-site estimate.

Animals in Chimney

What should I do if I find a bat in my living space?

Isolate the bat in one room, do not handle it, and call Suffolk County Health Department (516-227-9697) and your physician — a bat found in a living space is a potential rabies exposure event regardless of visible bites. After the immediate situation is handled, call DME Maintenance to schedule chimney cap installation to prevent re-entry.

Is a chimney inspection required when selling a home in Suffolk County?

What is a Level 2 chimney inspection and what does it include?

A Level 2 chimney inspection includes everything in a Level 1 inspection plus a video camera examination of the full flue interior.

DME Maintenance delivers a written report with photos of all findings the same day as the inspection.
