Emergency Chimney Service in Suffolk County — When to Call

Not every chimney problem is an emergency. But some are — and the consequences of treating an emergency as routine can be serious. This guide explains what qualifies as a chimney emergency in Suffolk County, what to do first in each scenario, and when to call DME Maintenance for priority service.

CO Alarm Sounding

This is the most serious scenario. If your carbon monoxide detector is sounding, evacuate immediately — everyone, including pets. Call 911 from outside. Do not go back inside to check the furnace or fireplace. Do not restart any appliances after the fire department clears the building until you have had the chimney system inspected. A blocked, cracked, or improperly lined flue is one of the most common causes of CO buildup in Suffolk County homes. Call DME Maintenance at 516-690-7471 for same-day or next-morning inspection after emergency services have cleared the scene.

Blocked Flue — No Heat in Winter

If your heating system is running but not venting — you're smelling exhaust, the system is shutting off on safety lockout, or you have visible soot near the appliance — stop running the appliance and call immediately. A blocked flue in winter is both a safety issue and a no-heat emergency. DME Maintenance prioritizes blocked flue calls from October through March. Common causes: animal nesting (birds, squirrels), debris accumulation, collapsed liner, or a damper that's stuck closed.

Chimney Fire

Chimney fires can be loud and dramatic — a roaring sound, visible flames or sparks from the top of the chimney — or they can be slow and quiet, burning inside the flue without obvious external signs. If you suspect a chimney fire, close the damper if you can do so safely, call 911, and evacuate. After the fire department clears the scene, do not use the fireplace or appliance again until a Level 2 inspection with camera has confirmed the liner is intact. Chimney fires frequently crack clay tile liners in ways that aren't visible without a camera.

Storm Damage

High winds, heavy snow loads, or a fallen tree can damage a chimney in ways that aren't immediately obvious from the ground. If you've had a major storm and notice anything different — a cap that's moved, visible mortar debris, a new lean to the stack, or water in the firebox that wasn't there before — call for an inspection before using the appliance. Structural damage to a chimney is a safety issue, not a cosmetic one.
