Famco Flue Liner Replacement Nationwide

Famco Flue Liner Replacement: The Ewing Owner’s Guide

We stock and install Famco-compatible flue liner replacement in Ewing, with most jobs running between $2,400 and $4,800 installed depending on height, diameter, and whether the chase needs reframing. Our trucks carry the common Famco diameters - 6″, 7″, and 8″ round in both rigid and flexible configurations - so we’re not ordering parts while your fireplace sits cold. Most Ewing homeowners discover the liner has failed when they spot white efflorescence staining the chimney breast, smell smoke in upstairs rooms during a fire, or their Level-2 inspection reveals gaps between liner sections that weren’t there five years ago.

Which Famco Models This Applies To

Famco built flue liners across several product lines from the late 1980s through the early 2010s, and the replacement part you need depends on which series was originally installed. The Famco FL-Series rigid liners - common in Ewing’s 1960s and 1970s colonials near the Ewing Lawrence border - used a single-wall construction with twist-lock collars every 18 inches. The later Famco Flex-Pro line switched to a corrugated 316Ti stainless with a different collar pitch, roughly 24 inches. Check the upper flue section near the thimble; if the label has weathered off, measure the inner diameter with a tape (not a guess by eye) and note whether the top termination is a standard rain cap or Famco’s older bell-top design, which requires an adapter we keep on the truck.

We are not affiliated with Famco. We source replacement liners from the same mills that supplied their OEM stock - 316Ti stainless for wood-burning, AL29-4C for condensing gas appliances - and we match spec-for-spec rather than selling you a “universal” kit that needs field modification. The aftermarket equivalent saves most Ewing homeowners 15% to 25% against a factory-ordered Famco-branded replacement with zero difference in service life. One compatibility gotcha: early Famco rigid liners used a 7.5-inch intermediate diameter that no current manufacturer stocks. We’ve handled three of these in Ewing over the past eight years, and in each case we fabricated a custom transition at our shop rather than forcing a 7-inch liner with a sloppy seal.

Signs Your Famco Flue Liner Replacement Is Failing

• White powder or crystalline staining on interior walls near the chimney. This is efflorescence from moisture migrating through cracked mortar joints in a deteriorating liner. In Ewing’s freeze-thaw climate, water trapped behind a failing Famco liner expands every winter and drives salts through the masonry. The stain is cosmetic; the saturated brick behind it is not.
• Smoke smell in second-floor bedrooms or attic space during fireplace use. Famco flex liners develop pinhole failures at stress points where the corrugation meets a collar. Combustion gases seep through gaps too small to see from below but large enough to pressurize wall cavities. A camera inspection finds these; a smoke test confirms them.
• Chunks of clay tile in the firebox or cleanout door. If your original chimney was clay-lined and a Famco retrofit liner was installed over it, the old terra cotta is now spalling from decades of thermal cycling. The Famco liner was meant to contain the flue gases; it was not meant to shore up collapsing clay behind it. Both need addressing.
• Visible gaps or separation between liner sections when viewed from the top. Famco’s twist-lock joints can back out from thermal expansion, especially in chimneys serving wood stoves that burn hot and cycle down overnight. A 3/8-inch gap at a joint is enough to cool flue gases below the dew point, accelerating creosote buildup and corrosion.
• Carbon monoxide detector alerts near the hearth or in basement utility rooms. This is the symptom that overrides all others. A breached Famco liner in a gas-venting chimney can dump CO into the house at levels that sicken before they alarm. We treat these calls as same-day priority, and we document the breach with camera footage before we touch anything.

Replacement Cost & What’s Included

What drives the range: height (every additional story adds roughly 12 feet of liner and labor), diameter (8-inch carries a 20% materials premium over 6-inch), and whether we need to remove an existing Famco liner that’s wedged itself tight from creosote glazing. Our estimate includes the liner, insulation wrap where code requires it, new connectors, top plate, rain cap, and disposal of the old material. We price upfront - the number on the estimate is the number on the invoice - and every liner replacement carries our 90-Day Done Right Promise in writing. If the draft doesn’t pull right or a joint we sealed shows smoke, we come back. No paperwork, no arguing.

DIY or Call Us?

There’s a short list of things an Ewing homeowner can safely check: confirm the damper opens fully, verify the chimney cap isn’t clogged with leaves, and look down the flue with a flashlight for obvious obstructions. Beyond that, flue liner replacement involves working at height on a pitched roof, handling sharp stainless edges, and setting a liner that weighs 80 to 150 pounds without kinking it or damaging the masonry crown. The real risk isn’t the fall - it’s the false confidence. We’ve been called to three DIY Famco liner jobs in Mercer County where the homeowner got the liner down but couldn’t achieve a proper seal at the thimble, or insulated the wrong side of the flex, or missed that the original clay liner had collapsed and was blocking the new one from seating. Each cost more to correct than our original estimate would have. If the flue is right, the fire takes care of itself. If it’s wrong, you’re heating the wall cavity or worse.

Call (856) 388-5580 and we’ll walk through what you’re seeing. If it sounds like a liner failure, we schedule the camera inspection, show you the photos, and give you a price before we order material.
