Most chimney companies don't publish prices. DME Maintenance does — because homeowners deserve to know what they're getting into before anyone shows up at their door. Here's what chimney services actually cost in Suffolk County in 2026, what drives the price up or down, and how to avoid paying more than you should.
Chimney Cleaning: $165–$295
A standard gas or oil flue cleaning in Suffolk County starts at $165 through DME Maintenance. That includes the cleaning, a Level 1 safety inspection, and a written report. Wood-burning fireplace chimney sweeps start at $195 due to the creosote removal involved. Pellet stove and wood stove cleaning starts at $195–$275 depending on configuration. What drives the price up: heavy creosote buildup (Stage 2 or 3), difficult roof access, dual flues, or secondary systems in the same visit.
Chimney Liner Installation: $1,670+
Stainless steel chimney liner installation for an oil-to-gas conversion or clay tile replacement starts at $1,400 in Suffolk County. Final price depends on flue height, liner diameter (typically 4", 5", or 6" for residential), insulation wrap requirements, and permit coordination. This is a factory-authorized installation with lifetime warranty on the liner. DME Maintenance provides a written, itemized estimate on-site before any work starts.
Chimney Repair: Free Estimate — Ranges Vary
Chimney crown repair starts at $395. Chimney pointing (tuckpointing) runs $400–$900+ depending on the extent of mortar damage. Chimney cap installation starts at $255 for a standard stainless steel cap. Flashing repair is quoted on-site based on extent and roof material. Waterproofing with ChimSaver is quoted after inspection. All repair work includes a free on-site estimate before any commitment.
What You Should Never Pay For
You should never pay for an estimate. DME Maintenance provides free on-site estimates for all repair work. You should not pay a diagnostic fee just to have someone look at your chimney — the inspection is included in the cleaning price. Be wary of any Suffolk County chimney company that quotes a cleaning price on the phone and then significantly increases it on arrival without a clear explanation. DME Maintenance quotes in writing and sticks to it.
