Chimney Blockage Removal in Nassau County
A blocked chimney is one of the most dangerous conditions in a home. Carbon monoxide, which is odorless and colorless, has no way to vent and migrates directly into living spaces. Nassau County's mature tree canopy and wildlife means chimneys without caps attract birds (starlings, sparrows, chimney swifts) and small mammals (squirrels, raccoons) as nesting sites. Debris blockages — fallen mortar, brick pieces, damaged cap components — are also common in older Nassau County homes. DME Maintenance removes blockages completely and installs a proper cap to prevent recurrence.

★★★★★Frequently Asked Questions
What causes chimney blockages in Nassau 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.
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.
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.
How do I know if my chimney is blocked?
Signs of a blocked flue include smoke entering the house when the fireplace is in use, the furnace or boiler safety shutoff triggering repeatedly, or a CO alarm activating. A blocked oil or gas flue is a serious safety situation — do not restart the appliance until the blockage is cleared. Call DME Maintenance at 516-690-7471.
How do you prevent chimney blockages?
A properly sized stainless steel chimney cap with screening prevents birds and animals from nesting in the flue. DME Maintenance installs caps on every blockage call — clearing the obstruction without capping is only solving half the problem.
