Famco Flue Liner Replacement Nationwide

Famco Flue Liner Replacement: The Woburn Owner’s Guide

We stock and install Famco-compatible flue liner replacement for Woburn homeowners, with most jobs running between $1,800 and $3,400 installed depending on height, diameter, and whether the existing liner pulls clean or needs extraction. In most cases we carry the correct diameter and alloy on the truck, so we’re not ordering parts and making you wait. Most Woburn owners discover their Famco liner has failed when they notice bits of terracotta in the firebox, a smoky smell that won’t clear, or the sweep’s camera shows gaps you can see from the ground.

Which Famco Models This Applies To

Famco manufactured a range of stainless steel and aluminum flue liners through the 1990s and 2000s, often sold through lumber yards and hearth shops without the model-specific documentation you’d get from a specialty brand. The most common units we pull out of Woburn chimneys are the Famco 316Ti flexible series in 6-inch and 8-inch diameters, and the heavier 304 alloy rigid sections used in some Montvale Avenue-area homes built in the 1980s expansion. The label, if it hasn’t corroded off, sits on a tag near the top termination or stamped on the collar plate.

Here’s the compatibility gotcha: Famco used a proprietary collar geometry on some flexible liner runs that doesn’t mate cleanly with standard DuraFlex or Olympia Chimney top fittings without an adapter plate. We’ve fabricated dozens of these transitions for Woburn homes, and we carry the adapter on the truck. For OEM-versus-aftermarket, Famco as a brand has been absorbed into larger distribution channels, so true OEM replacement is often unavailable or priced at a premium that doesn’t buy you better alloy. We match with 316Ti or 444 alloy equivalents that exceed the original spec and carry the same UL 1777 listing. The right call is matching alloy grade and wall thickness to your appliance’s venting requirement, not chasing a Famco box label.

Signs Your Famco Flue Liner Replacement Is Failing

• Flakes of metal or clay in the firebox. This means the liner wall has perforated or separated from the terra cotta surround. In Woburn’s freeze-thaw climate, condensation trapped between a failed liner and the clay flue accelerates spalling every winter.
• Smoke backing up into the room on startup. A liner with gaps or collapse creates pressure imbalances. The draft pulls from the path of least resistance, and if that’s a crack at the first offset, smoke follows.
• Water staining on the chimney breast or ceiling. Famco’s top fittings used a simpler seal design than current standards. Once the storm collar fatigues, Woburn’s driving northeast rains find the gap and run down the liner’s exterior.
• Strong odor even when the fireplace isn’t in use. Nesting material and creosote accumulate in gaps where the liner no longer presents a smooth surface. The smell is your warning that combustible buildup is exposed to flue gases.
• The sweep’s camera shows daylight through the wall. This is the definitive sign. If the inspection reveals perforation, separation at a joint, or the liner has pulled away from the top plate, replacement is not optional - it’s a fire and carbon monoxide exposure risk.

Replacement Cost & What’s Included

The range depends on three factors: how much of the old liner we can pull in one piece, whether the flue has offsets that require sectional navigation, and if the top plate and surround need replacement along with the liner itself. We price this upfront, in writing, before we book the job. The number on the estimate is the number on the invoice. Our 90-Day Done Right Promise covers the full installation, and we document the completed work with photos you can see and a plain-English verdict.

DIY or Call Us?

There’s a safe middle ground here, and then there’s where DIY ends. You can verify the diameter with a tape measure from the top, check that your cap and storm collar are intact, and confirm whether your appliance manual specifies 316Ti minimum alloy. What you should not do is attempt liner extraction or installation yourself. The old liner binds on mortar protrusions, offsets require controlled torque to navigate without tearing, and working at height on a Woburn colonial pitch with a heavy stainless coil is how people get hurt. More critically, an improper liner-to-appliance connection or missing clearance to combustibles creates a slow fire risk you won’t detect until it’s too late. We complete most Famco replacements in a single visit, with background-checked, uniformed technicians and no-hassle upfront pricing. Call (781) 404-3793 when you’re ready to have it done right.
