Famco Flue Liner Replacement Nationwide

Famco Flue Liner Replacement: The Alpharetta Owner’s Guide

If your Famco flue liner has failed, replacement in Alpharetta typically costs between $2,400 and $5,800 installed depending on length, diameter, and access. We stock Famco-compatible stainless steel liner sections and fittings on our trucks, so most Alpharetta homes get the full swap in a single visit. You’ll usually discover this part failed one of three ways: rust flakes in the firebox, a failed Level 2 inspection after buying or selling a home, or the smell of smoke drifting into the living room when the fireplace is running.

Here’s what that smell usually means: the inner wall of the liner has cracked or corroded through, and flue gases are escaping into the chase or wall cavity instead of venting to the outside. That’s not a nuisance, it’s carbon monoxide and heat moving somewhere it doesn’t belong. The good news is a Famco liner replacement is a straightforward, predictable job when it’s specified and installed right.

Which Famco Models This Applies To

Famco builds chimney liners and venting components used in a lot of the homes we service around Alpharetta, from subdivisions near Windward Parkway to older ranches off Rucker Road. The two things that determine which replacement part you need are diameter and material type. Most Alpharetta fireplaces and furnaces run either a 6-inch, 7-inch, or 8-inch liner. Famco makes both flexible stainless steel (usually 304 or 316 alloy) and rigid sections. You cannot swap a flexible section for a rigid one without checking clearances, and you absolutely cannot guess the diameter.

Look for a legible label or stamp near the top termination or at the appliance connection. If it’s gone, which happens after years of Georgia humidity and heat cycles, we measure the inner diameter and wall thickness on site before quoting anything. A key compatibility note: Famco flexible liners are sold in specific lengths and cannot be trimmed and re-crimped like ductwork. If your liner needs 22 feet, you buy the correct 22-foot-equivalent section, not a shorter one with a coupler. We use genuine Famco or fully equivalent trade-grade replacement sections, never generic dryer vent material that some handymen try to pass off because it’s cheaper.

Flint Chimney Co Alpharetta is an independent chimney service company and is not affiliated with Famco. We install and service their components the same way we do DuraFlex, HeatShield, and Gelco: specified to the job, priced in writing before work begins.

Signs Your Famco Flue Liner Replacement Is Failing

• Smoke odor inside the house during or after a fire. This is the most common first sign. A cracked liner lets flue gases bleed into the wall cavity instead of exiting through the top termination.
• Rust flakes or metallic debris in the firebox. Stainless steel liners corrode from the inside out, especially when condensation mixes with flue gas acids. Bits of scale falling into the firebox mean the liner wall is actively breaking down.
• Water staining on the ceiling or walls near the chimney chase. A failed liner lets moisture condense inside the chase, and that moisture finds drywall. In Alpharetta’s humid summers, this accelerates fast.
• A Level 2 chimney inspection flagged the liner. If you just bought or sold a home and the inspector noted flue liner damage, the photos are usually worth seeing yourself. We walk every customer through their own camera footage.
• Visible sagging or separation at a liner joint. Flexible liners can pull apart at couplings when the original install wasn’t secured correctly, especially after years of thermal expansion and contraction.

One dry observation from the field: Hank Delano has pulled liners out of Alpharetta chimneys that looked fine from the top but were paper-thin at the midpoint where condensation pools. Tell me what’s in the flue, and I’ll tell you what it takes to fix it. The only way to know is a camera inspection.

Replacement Cost & What’s Included

A Famco flue liner replacement in Alpharetta runs $2,400 to $5,800 installed. The main cost drivers are liner diameter, total vertical length, and whether the chase needs any repair work before the new liner goes in. A typical single-story fireplace with a 20-foot, 6-inch flexible liner lands on the lower end. A two-story home with an 8-inch liner, needing attic access and a deteriorated top plate, lands on the higher end. All of it gets itemized.

Your written quote includes the liner section itself, all required connectors and termination components, the removal and disposal of the old liner, and the full installation. Nothing is added at the door. Every liner replacement from Flint Chimney Co Alpharetta carries our 365-Day Done Right Promise in writing. If the covered repair fails within one full year, we come back at no charge. That’s the Garrison Standard on every job.

DIY or Call Us?

A liner replacement is not a DIY job, and this is why: you’re working inside a confined flue, often from roof level on a Georgia home with a 6/12 pitch or steeper. The liner has to be fed, centered, and secured so it doesn’t kink against the clay tile or masonry. A kinked liner that “looks close enough” will still leak. We’ve fixed more than one DIY liner install in Alpharetta where the homeowner spent a full weekend on the roof and ended up paying for the full job anyway.

What you can safely do is the legwork: note your fireplace or appliance model, measure the visible flue opening if you can reach it safely from inside, and take photos of any rust or debris you’re seeing. That prep actually helps us quote faster. But the measurement that matters, the inner diameter along the full run, has to be verified on site. Call (762) 600-1468 and we’ll get a tech out to look at it. The quote is free, and it’s in writing before you approve anything.
