Chimney relining is one of the most critical safety upgrades available to homeowners in Old Bethpage, NY — and one of the most frequently deferred. A failed, cracked, or undersized flue liner is not a cosmetic issue. It is a direct pathway for carbon monoxide and heat to escape the flue and enter your home's wall framing and living spaces. DME Maintenance installs UL-listed stainless steel chimney liners throughout Old Bethpage and all of Nassau County, NY, and we handle the full job — measurement, installation, top plate, cap, and connection to your appliance.
There are three situations in Old Bethpage where relining is required. First: oil-to-gas conversion. When a home converts from oil heating to natural gas, the original flue is typically oversized for the gas appliance. An oversized flue running a gas appliance creates condensation that rapidly deteriorates clay tile liners and causes back-drafting of CO into the home. Nassau County code requires relining when fuel type changes. Second: damaged liner. Clay tile liners crack from thermal shock, chimney fires, and decades of freeze-thaw cycling. A single crack in a flue liner is a fire and CO hazard. Third: appliance upgrade. Installing a high-efficiency furnace or insert requires a properly sized liner for the new appliance's venting requirements.
Every liner we install in Old Bethpage is UL-listed 2-ply 316L stainless steel, flexible or rigid depending on your flue configuration, sized precisely to your appliance's BTU output and venting requirements. Most liner installations in Old Bethpage are completed in a single day. We pull any required permits, handle all connections, and test for proper draft before we leave.
