Chimney relining is one of the most critical safety upgrades available to homeowners in Plandome, 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 Plandome 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 Plandome 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 Plandome 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 Plandome are completed in a single day. We pull any required permits, handle all connections, and test for proper draft before we leave. Chimney relining starts at $3050.
