Famco Flue Liner Replacement Nationwide

Famco Flue Liner Replacement: The Norwalk Owner’s Guide

A Famco flue liner replacement in Norwalk typically runs $1,400 to $2,800 installed, depending on the liner diameter, length, and whether we’re doing a straight swap or dealing with a deteriorated chimney interior. We stock Famco-compatible liners on the truck, and Wendell can usually have the job measured, quoted, and done within a week of your call. Most Norwalk homeowners find out their Famco liner has failed during an annual sweep, when the camera shows cracks, separation at the seams, or a liner that has started to pull away from the flue wall. Sometimes it’s a smell in the house or visible rust flakes on the hearth, but the camera is what tells the truth.

We’re an independent chimney company, so we install and service Famco products but have no corporate tie to the brand itself. That means we carry their liners because they hold up in Connecticut weather, and we stock the common sizes because waiting on a distributor in Ohio doesn’t help you in October when the nights are turning cold.

Which Famco Models This Applies To

Famco has built flue liners and venting components for decades, and the parts show up in oil furnace chimneys, gas water heater vents, and wood stove installations all over Norwalk. The lining kits are typically rigid stainless steel, double-wall, with a locking seam design. We routinely see Famco liners in 4-inch, 5-inch, 6-inch, and 8-inch diameters, and occasionally 7-inch on older setups. The make and model information lives on a small metal tag riveted near the appliance connection, but after thirty years in a damp Connecticut basement, those tags often rust to nothing. When the tag is gone, Wendell measures the liner diameter, checks the wall thickness with a micrometer, and matches the flue outlet on the appliance itself.

The real compatibility gotcha on Famco: their liners use a specific seam-lock profile, and generic aftermarket liners will not always seat to a remaining Famco section without an adapter. If you’re only replacing part of a run, you need to know whether you have the snap-lock or the twist-lock version. We carry both profiles on the truck, plus a drawer of Famco-compatible adapters and rain caps. When a full replacement makes better sense than patching, which it often does in Norwalk homes where the liner has been in since the Reagan administration, we quote the whole run installed and warrantied. A quality aftermarket liner from DuraFlex or HeatShield will sometimes save a couple hundred dollars, but for a straight Famco-to-Famco swap in the same diameter, OEM keeps the measurements simple and the fit exact. Wendell will show you both numbers and let you decide.

Signs Your Famco Flue Liner Replacement Is Failing

• Rust flakes or metallic grit collecting at the base of the flue cleanout. Water and acidic flue gases eat at stainless over time, and when the liner starts shedding particles, the interior wall is losing material, not just surface patina.
• A smell like wet ash or a sour chemical odor near the appliance. When the liner cracks or the seams separate, flue gases and moisture press into the chimney cavity instead of venting out the top.
• Visible cracks or dark staining on drywall near the chimney chase. Moisture escaping a failed liner condenses inside the chase and soaks into whatever surrounds it.
• The furnace or water heater burner flame flickers or burns yellow. Blocked or collapsing liner sections restrict draft, and the appliance starts burning dirty and producing carbon monoxide.
• White or brown streaks on the chimney exterior. Efflorescence and rust bleeding out of brickwork mean water is moving through the chimney in ways it should not, and a breached liner is the usual culprit Wendell finds in Norwalk when he follows those stains inside.

Replacement Cost & What’s Included

In Norwalk, we quote a Famco flue liner replacement as a flat installed price, not an estimate with asterisks. For a standard one-story chimney with good access, a 6-inch liner in a 25-foot run typically lands between $1,600 and $2,200. If the chimney is two stories, needs scaffolding, or the old liner is swollen with creosote scale and has to be cut out in sections, you could be at $2,800. The number Wendell gives you on the phone or after the site visit is the number on the invoice. Parts are itemized separately from labor, and the price includes the liner, top plate, rain cap, any required connectors, the full camera inspection after installation, and the written 90-Day Done Right Promise. If the fit isn’t right or the draft doesn’t improve, one call brings us back at no charge.

DIY or Call Us?

There is a version of this job a careful homeowner can do: measuring the liner diameter at the appliance connection and confirming it against the tag or flue outlet is a Saturday chore, not a service call. But pulling a 25-foot stainless liner down a flue, cutting it precisely, seating the locking seam under tension, and sealing the top plate requires the liner to go in straight, fully seated at every joint, and absolutely airtight at the connections. A liner that is crimped mid-run or poorly attached at the appliance collar is a carbon monoxide risk, and a liner left short at the top pulls rain and snowmelt into the chimney. For a part that carries exhaust out of your house, the install is not the place to learn by failing. Call (475) 375-2748 and we will measure, quote, and do the job right. If it does not need doing, Wendell will tell you.
