Famco Flue Liner Replacement Nationwide

Famco Flue Liner Replacement: The Bedford Owner’s Guide

We stock and install Famco-compatible flue liner replacement in Bedford, with typical installed pricing running $1,800 to $3,400 depending on chimney height, diameter, and whether the existing liner is a straight pull or requires partial disassembly. Most Famco replacements we book are completed in a single visit, and we carry the common diameters and flex lengths on our trucks. Homeowners usually discover the problem on the first cold snap in October or November, when smoke backs into the room, a downdraft sets off the CO detector, or an annual camera inspection reveals cracking, flaking, or rust-through that was not visible from the firebox.

Which Famco Models This Applies To

Famco manufactured several liner series over the decades, and the part you need depends on when your system was installed. The Famco Flex-Lite and Famco Pro-Flex lines, common in Westchester County homes built between 1985 and 2005, used 316Ti stainless in diameters from 3 to 8 inches. If your cleanout door or original paperwork is still intact, the model prefix is stamped on the collar tag, usually reading FL- or PF- followed by the diameter. No tag? We measure the flue opening and the chimney run with a drop tape before ordering anything.

We are an independent service provider, not affiliated with Famco. For most Bedford installations, we match OEM spec with DuraFlex or Gelco 316Ti equivalent, which meets the same UL 1777 listing and carries the same 20-year warranty. The only reason to hunt true Famco OEM is if your system uses the older Pro-Flex twist-lock couplings, which have a slightly different pitch than current industry standard. We check that on the first visit and stock both coupling styles.

Signs Your Famco Flue Liner Replacement Is Failing

• Smoke or odor seeping into upstairs rooms. A split or separated liner joint allows exhaust to leak into the chimney cavity, then find its way through gaps in the masonry into bedrooms above. In Bedford’s older colonials near Bedford Village, we see this most often where the liner passes through a second-story chase with settled framing.
• White or orange powder staining the firebox walls. This is flue gas condensate, usually from a liner that has rusted through or cracked, allowing moisture and acids to reach the brick. The orange tint means the steel is actively corroding, not just surface staining.
• Chunks of clay or metal flakes in the firebox after sweeping. Famco’s earlier galvanized connectors can delaminate after 15 to 20 years of freeze-thaw cycling in Bedford’s hard winters. What you are sweeping out is the liner wall itself.
• Draft that worked fine last season now requires the door cracked open. A collapsed or partially detached liner can create a reverse flow or choke the flue diameter. We check this with a smoke pellet and a manometer, not by guesswork.
• The CO detector chirps during a fire. Any combustion spillage is serious. We treat this as a same-day call, pull the camera, and show you exactly where the breach is before we quote any work.

Replacement Cost & What’s Included

What drives the range is not guesswork. It is chimney height, whether we can pull the old liner in one piece or cut it out in sections, and whether the top plate and termination need replacement too. Every estimate includes the liner, insulation blanket where code requires it, new top plate and rain cap, and a Level-2 camera inspection with photos you keep. We agree to the full number before we start. The number on the estimate is the number on the invoice.

Our 90-Day Done Right Promise covers the installation in writing. If it is not right, we come back. No paperwork to dig up, no arguing.

DIY or Call Us?

There is no safe DIY path for flue liner replacement. The work involves working at roof height on a steep pitch, handling sharp stainless edges, and properly sizing combustion air, all of which affect whether your fireplace vents safely. A liner that is even slightly undersized or improperly supported can overfire the appliance or spill carbon monoxide.

What you can safely check: look for the model tag, note any stains or debris, and listen for draft changes. Then call us. We will run the camera, show you the footage, and tell you straight whether the liner needs replacement now or can wait a season. If it needs doing, we will tell you. If it does not, we will tell you that too. Call (914) 409-9387.
