Famco Flue Liner Replacement Nationwide

Famco Flue Liner Replacement: The Framingham Owner’s Guide

Famco flue liner replacement in Framingham typically runs $1,800-$3,400 installed, depending on liner diameter, height, and whether the existing liner pulls out clean or has to be cut out in sections. We stock Famco-compatible stainless steel liners and connector components for same-day installation on most standard chimney configurations. If you’re seeing rust flakes in your firebox, smelling smoke in upstairs rooms, or your carbon monoxide detector has chirped once near the hearth, the liner is the first place we point the camera.

Most Framingham homeowners discover a Famco liner problem during a routine sweep or after a home inspection flags “suspected flue liner deterioration.” The tell is usually a thin, orange-brown dusting at the damper or a vertical crack visible only when the camera light hits it at the right angle. In older colonials near Cushing Memorial Park, we’ve found original Famco liners from the 1980s and 90s that look fine from the top but are paper-thin at the smoke chamber bend, where acidic condensation pools.

Which Famco Models This Applies To

Famco manufactured several liner series over the years, and the part you need depends on when your system was installed. The most common in Framingham homes are the Famco 304-alloy smooth-wall liners (sold in 6″, 7″, and 8″ diameters) and the earlier corrugated 316-alloy flex liners labeled “Famco-Temp.” The model number is stamped on a metal tag at the top termination, if it hasn’t corroded off. If the tag is gone, we measure inner diameter with a flue gauge and check wall thickness with a borescope; 304 liners under .006″ at any point are done.

We source replacement through Haven’s buying network, which includes Famco-spec materials from Olympia Chimney and Gelco. For most Framingham installations, a quality aftermarket 316Ti stainless liner outperforms original Famco 304 at a lower material cost, and it carries the same 15-year warranty when we install it. The exception is pre-1990 Famco systems with proprietary top-sealing dampers; those need a custom adapter plate we fabricate on site. Corrine Halstead keeps the dimensions for common Framingham housing stock in her field notes, so we rarely need a second trip.

Signs Your Famco Flue Liner Replacement Is Failing

• Rust-colored debris below the damper. Stainless steel doesn’t rust, but the weld seams and outer jacket on older Famco liners do. What you’re seeing is oxidized steel flaking off the liner’s exterior layer, which means the inner wall is compromised and exhaust gases are reaching the chimney’s masonry surround.
• Smoke smell in second-floor bedrooms during fireplace use. A cracked or separated Famco liner allows smoke to leak into the chimney cavity, then find gaps around the thimble or framing. In Framingham’s tight colonial floor plans, that smoke travels through interior walls faster than you’d expect.
• White, chalky efflorescence on the exterior brick. This is moisture carrying combustion acids through a breached liner, then evaporating at the brick surface. It’s not just cosmetic; the acids are eating the mortar from inside out, and freeze-thaw cycles in MetroWest winters accelerate the damage.
• Carbon monoxide detector activation near the hearth. A liner with pinholes or a failed seam can push CO into living space at low levels that trigger sensitive detectors before you’d smell anything. This is not a detector malfunction. This is a liner that needs immediate inspection.
• The sweep’s camera shows a “shiny spot” that doesn’t move. What looks like a reflection is often a hole burned through the liner wall, with the camera light shining on masonry behind it. We’ve caught these in Famco liners that passed a flashlight inspection from the top.

Replacement Cost & What’s Included

What drives the range: liner diameter, total length, whether the existing Famco liner is stuck with creosote cement (common in Framingham’s heavy oak-burning households), and if the top plate or rain cap needs replacement too. Every quote is written before work starts, with the scope, the price, and the warranty on one page. Clause 4 of the Haven Standard requires a photo record on every job, so you’ll get camera footage of the old liner coming out and the new one seated, plus a written warranty card. The 365-Day Done Right Promise applies to all liner work. If you’re holding a competitor’s written estimate, we’ll review it for free.

DIY or Call Us?

There’s exactly one thing a homeowner can safely check: look up the flue from the firebox with a flashlight for obvious gaps, holes, or collapsed sections. Do not attempt to remove or install a flue liner yourself. The liner is a tension-fit system secured at the top with a plate that requires working at roof height, and the old liner often weighs 40-80 pounds of sharp, creosote-coated steel. More critically, a liner installed without proper sizing or sealing creates a carbon monoxide pathway you won’t detect until it’s too late. NFPA 211 requires a Level 2 inspection with camera verification after any liner installation. We include that inspection as standard, not an add-on.
