Famco Flue Liner Replacement Nationwide

Famco Flue Liner Replacement: The Marietta Owner’s Guide

Famco flue liner replacement in Marietta typically runs $1,100 to $2,400 installed, depending on the diameter, length, and whether the old liner is still structurally sound enough to pull cleanly. We stock Famco-compatible stainless steel liner systems on our trucks, which means most Marietta replacements happen in a single visit, usually 3 to 5 hours from setup to final inspection. Most homeowners discover a failed Famco liner two ways: a chimney sweep flags it during an annual inspection, or they notice rust flakes, a faint smoke smell indoors, or visible deterioration at the chimney cap.

Here’s what you should know before you call anyone: not all Famco liners fail the same way, and the wrong replacement liner creates problems a camera inspection will catch later, but you’d rather catch before you spend the money. This page covers exactly what we see in Cobb County homes, what things actually cost, and when a Famco liner genuinely needs to come out versus when it can wait.

Which Famco Models This Applies To

Famco has manufactured flue liners and chimney components for decades, and the product line splits broadly into rigid stainless liners and flexible corrugated liners, most commonly in 4″, 5″, 6″, and 8″ diameters. Most Marietta homes we service have Famco flexible liners paired with gas furnaces, water heaters, or fireplaces. The rigid Famco sections show up more often in wood-burning appliance venting, especially in older ranch and split-level homes around East Cobb and Kennesaw Avenue.

Here’s the compatibility gotcha we run into regularly, because it’s the thing that catches homeowners off guard: Famco flexible liners are sized by actual inside diameter, not outside diameter, and the corrugation profile differs from DuraFlex and Gelco equivalents. That means a “6-inch” liner from one brand doesn’t always couple cleanly to a Famco connector on the other end. When we replace a Famco liner, we match the inside diameter and verify the coupler fit with a camera before we seal anything. You can find the original size printed on a metal tag near the termination point; when that tag’s gone, we measure the flue opening and the appliance collar.

On the OEM-versus-aftermarket question: Famco original replacement parts are solid, but we install Famco, DuraFlex, HeatShield, and Gelco liners depending on the application, and we’re upfront about when a direct Famco replacement matters and when a quality UL-listed compatible liner performs identically. For gas appliances, any UL 1777-listed liner engineered for that fuel type does the job. For wood-burning, we match the alloy grade and wall thickness to the appliance’s heat output, because that’s where substitutions go wrong. We’re an independent service provider; we’re not affiliated with Famco, and that’s exactly why we can tell you when a different liner brand is the better call.

Signs Your Famco Flue Liner Replacement Is Failing

Here’s what failing Famco liners actually look like in Marietta homes, and why each symptom shows up:

• Rust flakes or staining at the chimney base or around the appliance vent connection. Georgia’s summer humidity and winter temperature swings create condensation inside the flue, and that moisture attacks the liner wall, especially where the inner liner has already thinned from years of acidic flue gas exposure.
• A smoke or soot smell indoors with no fireplace running. A compromised liner lets flue gases drift into the chase cavity or wall interstitial space instead of up and out, and that odor is usually first noticeable in upper rooms or when the HVAC cycles.
• Visible gaps, bulges, or pancaking in the flexible liner when viewed from the top. This is a thermal-fatigue failure, and we see it most often in liners that have survived 15 to 20 years of Cobb County’s freeze-thaw cycles, especially on chimneys with poor cap coverage.
• Water in the firebox or rust streaks on the damper after rain. A liner that has pulled apart at a seam or corroded through near the top lets water in directly, and by the time you see rust streaks, the liner’s structural integrity is already compromised.
• Carbon monoxide detector alerts or a stove that backdrafts when the furnace kicks on. A liner that has collapsed internally restricts draft and can push exhaust back into the home. If this is happening, stop using the appliance and call us immediately at (229) 350-8952.

Replacement Cost & What’s Included

Here’s what Famco flue liner replacement actually costs in Marietta, and what that number includes:

What drives the range: liner diameter and length, whether we need to remove and replace the crown or top plate, how much scaffolding or roof access the job requires, and whether the old liner comes out clean or fights us the whole way. Every quote we write includes the liner, connectors, insulation where required, labor, cleanup, and a written before-and-after camera report. You get the price in writing before any work starts. That’s non-negotiable with us.

Every Famco liner replacement we install carries a written guarantee. If the repair fails within the coverage period, the second visit is free. That’s the 365-Day Done Right Promise, and it’s included on every job, no fine print needed.

DIY or Call Us?

Honestly, a flue liner replacement is not a DIY job, and I’ll tell you why straight: you’re working at roof height with a heavy, awkward, corrugated stainless tube that doesn’t want to negotiate corners, and if you drop it or misjudge the angle, you’re looking at a damaged crown, cracked flue tiles, or a fall. We carry professional fall protection and have pulled hundreds of liners in Marietta without incident, and we’ve also fixed the aftermath of owner attempts that went sideways.

What you can safely do yourself: inspect visible portions of the liner from the ground with binoculars, check for rust stains around the appliance connection, and listen for unusual drafting sounds. If anything looks off, call us at (229) 350-8952. We’ll camera the full liner top to bottom, show you the footage, and tell you plainly whether the liner needs replacing now or has another season in it. Tell me what you’re seeing and I’ll tell you exactly what it means, no guesswork, no upsell.
