Famco Flue Liner Replacement Nationwide

Famco Flue Liner Replacement: The New City Owner’s Guide

We stock and install Famco-compatible flue liner replacement in New City, with most jobs running $1,800 to $3,400 installed depending on height, diameter, and whether the existing liner pulls clean or needs section-by-section extraction. If we have your diameter in our Rockland County warehouse, we can usually inspect, measure, and install within a single booked visit. Most New City homeowners discover their Famco liner has failed when they spot thin flakes of stainless steel in the cleanout, smell smoke in an upstairs bedroom during a fire, or get a failed Level-2 inspection report pointing to gaps or corrosion at the seam joints.

Which Famco Models This Applies To

Famco built several liner series over the years, and the replacement part you need depends on which generation is in your chimney. The earlier Famco rigid 316Ti stainless liners, common in New City homes built between 1985 and 2005, carry a .012-inch wall thickness and use a male-to-female twist-lock seam every 12 inches. The later flexible Famco ProFlex and Famco SmoothWall lines switched to a corrugated 316L alloy with a .005-inch wall and a different collar diameter at the top plate. We see both in this market, often in the split-level and raised-ranch stock near New City’s Clarkstown neighborhoods where original builders spec’d Famco for oil-to-gas conversions.

To identify yours: check the top plate or termination cap for a stamped Famco logo and series marking. If the chimney is active, do not climb to look. We read that label with our camera during the initial inspection. For the OEM-versus-aftermarket question, Famco as a brand has shifted distribution channels twice in the past decade. We source replacement liner sections and collars through Famco’s current supply chain where the exact spec still exists, but we also keep compatible 316Ti rigid and 316L flexible inventory from Olympia Chimney and Copperfield that meets the same UL 1777 listing. The aftermarket equivalent often runs 15 to 20 percent less on material cost with no difference in service life. In New City’s freeze-thaw climate, what matters more than brand name is wall thickness at the seams and proper top-sealing to keep condensate from pooling.

Signs Your Famco Flue Liner Replacement Is Failing

• Metallic debris in the cleanout or firebox. This is the tell we watch for on every inspection. When a Famco liner’s 316Ti seam welds fatigue after twenty-plus New City winters, the metal sheds thin crescent-shaped flakes that collect below the smoke chamber. If you sweep these out and they return within a season, the liner wall is actively deteriorating.
• Smoke odor in upstairs rooms or attic space. A compromised Famco liner joint or pinhole corrosion allows exhaust to escape the flue path. In New City’s older colonials with framed chases, that smoke finds wall cavities and bedroom registers. The smell lingers because creosote-laden exhaust carries a distinct acrid note that standard air fresheners do not mask.
• White or orange staining on exterior masonry below the chimney crown. This indicates condensate bleeding through mortar joints, which happens when a Famco liner no longer maintains proper draft temperature. Cold-start appliances, common in homes near New City’s reservoir area where basements run cooler, accelerate this pattern.
• Visible gaps or daylight through the liner wall on camera inspection. Our Level-2 inspection pushes a camera the full flue length. A healthy Famco liner shows continuous metal with uniform light reflection. Pitting, holes, or separated seams show as bright spots where the camera light blows through to the brick beyond.
• Appliance backdraft or difficulty starting fires that used to light easily. A failing Famco liner loses its smooth interior surface. Creosote builds in the irregularities, narrowing diameter and choking draft. In New City’s hillside homes with exterior chimneys on the north face, this combines with cold-stack syndrome to make lighting even seasoned hardwood a chore.

Replacement Cost & What’s Included

For a standard single-flue Famco liner replacement in New City, our installed pricing breaks down as follows:

• Short run (one story, straight shot): $1,800 - $2,400
• Medium run (two story or moderate offset): $2,400 - $2,900
• Tall or complex run (three story, tight offset, or liner extraction required): $2,900 - $3,400

What drives the range: chimney height from appliance to crown, whether the existing Famco liner pulls out in one piece or fractures and requires section-by-section removal, and whether the top plate and termination cap also need replacement. Every estimate includes the Level-2 camera inspection, photo documentation you can see, the liner material and insulation wrap where code requires it, new top plate and rain cap, and disposal of the old liner. We agree to the full price before booking. The number on the estimate is the number on the invoice. Our 90-Day Done Right Promise covers the installation in writing, no arguing. If it’s not right, we don’t leave until it is.

DIY or Call Us?

There is no safe DIY path for flue liner replacement. The work involves working at height on a pitched roof, handling sharp stainless steel edges that will slice through standard work gloves, and properly sizing draft to appliance output. A mismeasured liner that bottoms out six inches short of the appliance collar creates a creosote trap and carbon monoxide hazard. An uninsulated liner in an exterior New City chimney will condense acidic moisture that destroys the new metal in half its rated life. What you can safely check: look in your cleanout for metal flakes, note any smoke odors, and confirm your carbon monoxide detectors are under ten years old and have fresh batteries. After that, call us at (845) 599-0930. We carry Famco-compatible diameter stock on our trucks, and Russell Haines or one of our background-checked, uniformed technicians will inspect, measure, and quote before any work begins.
