Famco Flue Liner Replacement: The Norristown Owner’s Guide

We stock and install Famco-compatible flue liner replacement in Norristown, typically running $1,800-$3,400 installed depending on liner diameter, chimney height, and whether the existing liner pulls out clean or has to be cut out in sections. Most Famco replacements we book are completed in a single day, and we carry common diameters on our trucks for the 5.5-inch and 6-inch round liners that show up most often in the pre-1990s brick colonials around Elmwood Park and the Main Street corridor. The camera found it. The report names it. The price is written down. That’s where we start.

Most Norristown homeowners discover their Famco flue liner is shot during a routine sweep when our camera hits a gap, a rust-through, or a section that’s dropped and is venting into the masonry instead of up the flue. Others smell smoke in the living room during a cold snap, or their carbon monoxide detector chirps after the first fire of the season.

Which Famco Models This Applies To

Famco built flue liners under several product lines over the decades, and the label on your existing liner, if it’s still legible, is the fastest way to match it. Look for a stamped metal tag near the top of the chimney or a printed band on the liner itself: series numbers starting with FLR (round flexible) or FLS (smooth-wall rigid) are the most common in Montgomery County installations from the 1970s through the early 2000s. If the tag is gone, we measure the flue opening at the thimble and the chimney top, then run the camera to confirm whether you’ve got a 5.5-inch, 6-inch, or 7-inch round, or one of the older oval profiles Famco produced for oil-to-gas conversions.

OEM Famco liners are no longer manufactured, but we source direct-fit replacements through our Haven buying network from Famco’s original supplier channels, plus quality aftermarket equivalents from DuraFlex and Olympia Chimney that match the same UL 1777 listing. The aftermarket route saves most Norristown customers $200-$400 without giving up wall thickness or corrosion resistance, and we specify which route we’re proposing in writing before any work starts. One compatibility gotcha: Famco’s early FLR-55 series used a slightly heavier gauge collar at the thimble connection that doesn’t seat cleanly on modern flex adapters. We’ve got the transition fittings on the truck, but it’s why we always camera the full run before quoting.

Signs Your Famco Flue Liner Replacement Is Failing

• Smoke or exhaust odor inside the home. A separated or perforated Famco liner leaks combustion gases into the chimney cavity, and from there they find paths through mortar joints into living spaces. In Norristown’s older brick homes with balloon framing, that path is often a wall cavity or the floor joist bay above the fireplace.
• White or orange staining on the exterior chimney brick. This is condensate and creosote migrating through cracked mortar joints because the liner is no longer containing the flue gases. The freeze-thaw cycle in Pennsylvania winters accelerates the spalling once that moisture gets into the brick.
• Chunks of clay or metal in the firebox or cleanout. Famco’s rigid FLS sections can crack from thermal shock after decades of oil-fired service; flex sections can fatigue and shed collar fragments. Either way, debris below the damper means the liner’s structural integrity is compromised.
• Draft problems that get worse in cold weather. A liner that’s dropped out of alignment or collapsed internally creates turbulence instead of a smooth draw. Norristown’s January temperature swings, especially the single-digit nights that follow a thaw, make this obvious fast.
• Your sweep flags “gaps visible on camera” but the liner looks fine from the top. Famco flex liners often fail at the middle sections where they bear against a chimney offset or where a support plate has corroded. The damage is below the roofline and invisible without a camera scan.

Replacement Cost & What’s Included

What drives the range: chimney height, number of offsets, whether the existing liner extracts in one piece or has to be sectioned out, and whether the smoke chamber needs parging while we’re inside. Every quote we deliver in writing under Haven Standard Clause 1 lists the liner gauge (we use .005″ minimum for oil, .006″ for wood), the exact footage, and the warranty term. Our 365-Day Done Right Promise applies to the installation, and the liner itself carries a lifetime warranty through the manufacturer. Materials are sourced through our Haven buying network from Famco, DuraFlex, HeatShield, Gelco, and Olympia Chimney specifically to keep customer prices honest.

DIY or Call Us?

There’s exactly one thing a homeowner can safely check: look down the flue from the fireplace opening with a flashlight for obvious gaps, debris, or daylight where the liner should be continuous. Don’t climb the roof, and don’t attempt to pull or install a flue liner yourself.

Flue liner replacement involves working at height on a chimney top, handling sharp stainless edges, and properly sizing draft for the appliance below. More critically, an improperly seated liner vents carbon monoxide into the home, and you won’t know it’s wrong until someone gets sick or a detector sounds. In Pennsylvania, Montgomery County requires a permit for liner replacement, and the work must pass inspection. We’re licensed for this work, we pull the permit as part of our scope, and we warranty what we install. Call (484) 552-9695 and we’ll camera it, price it in writing, and schedule it.
