Famco Flue Liner Replacement Nationwide

Famco Flue Liner Replacement: The Atlanta Owner’s Guide

If your Famco flue liner has failed, we carry and install Famco-compatible replacement liners across Atlanta, with most replacements running $1,800 to $3,400 installed depending on flue height, diameter, and access. We keep common Famco sizes on the truck, which means many Atlanta homes get the swap done the same day as diagnosis. Most homeowners find out their liner has failed one of two ways: a flue inspection shows cracked or separated sections, or the smell of smoke and gas fumes starts drifting back into the house even when the damper is open.

Famco makes a solid liner, but like every liner, it eventually wears out. In Atlanta’s climate, the failure usually isn’t from overfiring a woodstove. It’s from years of condensation, creosote, and the freeze-thaw cycles that stress the joints in older masonry chimneys around neighborhoods like Decatur, Grant Park, and East Point. Ruben Castellano has pulled enough Famco liners out of Atlanta chimneys to know exactly what the wear pattern looks like, and what’s actually worth salvaging versus what has to come out.

Which Famco Models This Applies To

Famco’s flue liners fall into two broad camps: rigid stainless sections (typically 304 or 316 alloy, usually 5.5-inch to 8-inch diameter) and flexible corrugated liners used for retrofit installs through existing flues. If you’re looking at a failed liner, the part that usually needs replacing is the liner itself, not the cap or the connector, and the repair path depends on which type you have.

Here’s the compatibility gotcha most Atlanta homeowners run into: a Famco rigid liner is not a universal drop-in. The outside diameter varies slightly between production runs, and if your flue has even a quarter-inch offset, a rigid section won’t seat properly without cutting. We measure the inside flue diameter, not the old liner’s outside, before ordering anything. You can find the model and diameter on a stamped tag riveted near the top section, but a decade of creosote often hides that tag completely. When it’s unreadable, we go by flue measurement, not guesswork. For the OEM-versus-aftermarket call: Famco’s own replacement sections are the most predictable fit, but a quality 316 stainless liner from DuraFlex or Gelco often outperforms the original if the furnace or stove gets heavy seasonal use. We install all three, and we’ll tell you which one actually makes sense for your setup.

Signs Your Famco Flue Liner Replacement Is Failing

• Smoke backing up into the room when the fire’s lit. This usually means the liner has separated at a seam or collapsed internally, so exhaust is escaping into the chimney cavity instead of venting upward.
• A persistent smoky smell even days after the last fire. Creosote is absorbing into the brick behind the failed liner, and that smell doesn’t leave on its own.
• Gas furnace or water heater exhaust smell inside the home. If your Famco liner vents a gas appliance and you’re catching that sulfur-like odor, the liner may have cracked from acidic condensation, a known wear pattern on gas venting systems.
• Visible rust streaks or water stains on the ceiling or wall near the chimney chase. A perforated liner lets condensation migrate into surrounding framing, which is also how you get hidden mold in Atlanta’s humid summers.
• Flakes of metal or creosote at the base of the fireplace or cleanout door. When liner sections start physically degrading, you’ll see the crumbs before you see the full collapse.

Replacement Cost & What’s Included

A Famco-compatible flue liner replacement in the Atlanta area typically runs $1,800 to $3,400 installed. Single-story homes with straightforward flue access sit at the lower end, while two-story chimneys, steep roof pitches common in older Druid Hills and Virginia-Highland homes, or chimneys that need scaffolding land at the higher end. The liner itself is usually $40 to $70 per foot depending on diameter and alloy, and the rest is labor, removal of the old liner, sealing, and reconnection to your appliance.

Every quote we write in Atlanta includes the removal of the old liner, installation of the new one, a full inspection of the surrounding flue cavity, and a written price before any work begins. No surprise line items after we start. Every replacement carries our 365-Day Done Right Promise: if the repair fails within a year, the second visit is free, period. That’s not a limited warranty with fine print and exclusions. That’s the deal.

DIY or Call Us?

This is not a part you safely replace yourself. A flue liner carries hot exhaust gases, carbon monoxide, and creosote away from combustible framing, and a liner that’s installed wrong or poorly sealed is a carbon monoxide risk that doesn’t announce itself until someone’s dizzy or worse. We’ve seen well-intentioned DIY jobs in Atlanta where the liner was connected backwards at the tee, where the joints weren’t sealed with the right cement, and where the wrong alloy got used for a wood-burning appliance. None of those fail loudly.

What you can safely check yourself: look for visible rust, separated joints, or flaking metal at the cleanout door, and note any smoky smells inside. But even an upper-flue problem won’t be visible from the firebox. If you’re seeing or smelling anything that makes you think the liner is compromised, call (762) 356-6423. We’ll inspect it with a camera, show you exactly what we found, and hand you a written quote. Tell me what you’re seeing, and I’ll tell you what it actually means.
