Famco Flue Liner Replacement Nationwide

Famco Flue Liner Replacement: The Marietta Owner’s Guide

We stock and install Famco-compatible flue liner replacement parts throughout Marietta, and a full replacement typically runs $1,800 to $3,600 installed, depending on the liner length and whether we’re working on a single-story or two-story chimney. Most owners discover the liner has failed during a routine sweep, when our camera shows corrosion or separation that’s been brewing for years, or after a home inspection flags it before a sale. The good news: if we have your size on the truck, we can usually have the old liner out and the new one in the same day. Here’s what you need to know about the part, the cost, and what actually makes a Famco liner fail in Georgia’s climate.

Which Famco Models This Applies To

Famco manufactures flexible stainless steel chimney liners in a range of diameters, and we work with their 316L alloy liners most often. That’s the higher-grade stainless designed for gas and oil appliances, and it’s the one we recommend for Marietta homes because it holds up measurably better against the acidic condensate that forms when a furnace or water heater vents through a chimney. The compatibility question usually comes down to three things: diameter, length, and what the liner is venting. Famco liners for gas appliances run smaller, typically 3 to 5 inches, while liners serving wood-burning fireplaces or larger stoves run 6 to 8 inches. If you can find the metal tag on the liner’s top plate or check the original install paperwork, you’ll see the diameter stamped there. No tag? We measure it during the inspection before we ever quote a replacement.

One thing worth saying plainly: we’re an independent chimney service company, not affiliated with Famco, so when we recommend an OEM Famco liner or a quality aftermarket equivalent, our only interest is what fits and lasts. In most cases, the aftermarket 316L liner from DuraFlex or Gelco performs just as well as the Famco-branded version in Marietta’s venting conditions, and it often costs $200 to $400 less for the material. If your system was originally built around a specific Famco part and the manufacturer’s warranty is still active, we’ll tell you if OEM is the smarter call. Candidly, most liners we see have been out of warranty for years by the time they fail.

Signs Your Famco Flue Liner Replacement Is Failing

• Flue gases smelling inside the house, especially near the fireplace or utility room. A failing liner lets combustion byproducts seep into living spaces instead of venting up and out, and the vinegar-like oder of acidic condensate is a common tell with gas appliances.
• Visible rust or moisture staining on the chimney exterior or in the firebox. A corroded liner lets moisture through the chimney wall, and in Marietta’s humid summers plus winter freeze-thaw cycles, that moisture accelerates the damage quickly.
• Flakes of metal or rust-colored debris in the firebox or at the cleanout door. This is the liner delaminating from the inside, and if you see it, the liner is usually past repair and needs replacement rather than patching.
• The water heater or furnace keeps tripping or running inefficiently. A restricted or collapsed liner can choke off the appliance’s draft, which makes the system work harder and can lead to carbon monoxide issues with gas appliances.
• Our camera inspection shows separation at the seams or a tear we can measure. We don’t recommend a liner replacement without showing you the footage. You’ll see exactly what we see, and if the damage is limited to one small section, we’ll say so honestly rather than selling a full swap you may not need yet.

Replacement Cost & What’s Included

In Marietta, a full Famco flue liner replacement runs $1,800 to $3,600 installed. The range comes down to three factors: liner length (a single-story chase is shorter and easier to access than a two-story chimney), diameter (larger liners cost more per linear foot), and whether the old liner comes out cleanly or fights us on the way out. The price includes the liner itself, the top plate and connector, removal of the old liner, installation, and a full camera inspection afterward so you can see the finished result with your own eyes. We give you a written price before any work starts, and that’s the price you pay, whether the job takes two hours or five. The repair carries Hadley Chimney Marietta’s 365-Day Done Right Promise: if the replacement fails within a year, we come back and fix it at no charge. No fine print, no exclusions buried in a form.

DIY or Call Us?

We’ll be honest with you here, because this is one of the few chimney jobs where DIY genuinely crosses into risky territory. You can safely shine a flashlight up the flue to look for obvious rust or tears, and you can check the cleanout door for metal flakes. That’s worth doing. But pulling and replacing a flue liner means working on a roof, handling a 20 to 35 foot section of flex liner that wants to kink, and getting the connector sealed correctly enough that flue gases don’t leak into your attic. The consequence of getting the seal wrong isn’t a drafty fireplace, it’s carbon monoxide in the house. That’s not a scare line, it’s the physics of the job. If you suspect your liner is failing, call us at (762) 249-4619, and we’ll put a camera on it and show you exactly what’s going on before we touch a tool.
