Famco Flue Liner Replacement Nationwide

Famco Flue Liner Replacement: The Fort Worth Owner’s Guide

We stock and install Famco-compatible flue liner replacements across Fort Worth, with most complete liner swaps running $1,800 – $3,400 installed depending on liner diameter, length, and whether your chimney needs an insulation wrap. Most owners discover their Famco liner has failed either during a routine sweep when our camera finds hairline cracks, or after noticing flue gases backing up into the house on a cold night. Here’s the part most people don’t hear until it’s too late: a stainless liner in a Fort Worth chimney sees wild temperature swings, and the expansion and contraction is what eventually fatigues the metal, not just the creosote sitting on top of it.

Key takeaways:

• Famco liners are sized by inner diameter (4″ – 8″ is the common range for residential), so matching is about measurements, not just the brand name.
• We carry Famco-compatible stainless liners on the truck for common sizes; oddball diameters get ordered and installed within the week.
• Every replacement includes a camera inspection before we touch anything, so you see the failure for yourself.
• The work carries our 365-Day Done Right Promise, in writing, before we start.

“I’d rather show you a photo of the problem than hand you a bill you don’t understand.” That’s how Cory Mitchell runs every liner job, and why we don’t recommend a single replacement part until our camera has been through the flue and you’ve seen the footage.

Which Famco Models This Applies To

Famco makes flexible stainless steel chimney liners under a few product lines, and the replacement path depends on which one your Fort Worth home has. The Famco FlexKing and standard 316Ti alloy liners are the two we see most often in this market, with FlexKing being the premium 316Ti option rated for higher-temperature, continuous burn conditions. If you’ve got the original box or install paperwork, look for the liner diameter printed on the label; if you don’t, we measure the inner diameter directly during the camera inspection.

The compatibility gotcha most Fort Worth owners run into: Famco liners are sold by inner diameter, but many homeowners measure the outside or guess based on the flue tile opening. Get this wrong and you’ll be trying to pull a 6″ liner through a 5.5″ old clay tile opening, which doesn’t work. We verify both the liner size and the throat opening before recommending anything. On the OEM-versus-aftermarket question, the honest answer is this: Famco no longer sells direct to most local chimney companies, so what we install is a Famco-compatible 316Ti liner from a supplier we’ve trusted for years, matched to the same gauge and diameter specs as the original. The alloy matters more than the logo stamped on the box, and 316Ti is what we’d put in our own flue.

Signs Your Famco Flue Liner Replacement Is Failing

• Condensation staining on the chimney exterior. When a stainless liner develops pinholes or cracks, flue gases cool too fast inside and produce acidic condensation that bleeds through masonry. You’ll see dark stains or white efflorescence on the chimney face, especially after cold snaps in Fort Worth winters.
• A metallic, chemical odor near the fireplace. Flue gases that should vent upward are escaping through cracks in the liner and drifting back into the room. This isn’t a musty smell; it’s sharp and unnatural, and it means the liner is compromised, not just dirty.
• Visible rust flakes in the firebox. Older Famco liners that weren’t 316Ti alloy will eventually rust through, especially if the chimney cap leaked and let rain sit on the liner interior. If you see rust chips, the liner is done.
• Spalling flue tiles showing up in the firebox. When the liner fails and heat escapes into the clay tile void, old clay tiles crack and drop pieces. That’s a red flag the liner isn’t doing its job anymore, and it should not be ignored.
• Our camera found it before you felt a thing. Hairline cracks and early-stage pitting don’t always produce obvious symptoms. That’s why we camera every chimney before and after a sweep in Fort Worth, so you’re not making repair decisions in the dark.

Replacement Cost & What’s Included

Here’s what a Famco flue liner replacement typically runs in Fort Worth, installed, with all parts and labor:

• 4″ – 5″ diameter liner, single-story run: $1,800 – $2,300
• 6″ – 7″ diameter liner, standard two-story run: $2,200 – $2,900
• 8″ diameter liner or longer/complex runs: $2,800 – $3,400
• Insulation wrap add-on (recommended for exterior chimneys): $350 – $600

The range exists because every Fort Worth chimney is different: linear feet of flue, whether your chimney is interior or exterior, and whether the crown needs sealing at the same time. Our written price is given before work starts, full stop. It includes the liner, connectors, top plate, new rain cap if needed, and a full camera re-inspection after the pull so you see the finished install. Every liner replacement carries our 365-Day Done Right Promise, in writing, with a free second visit if the repair fails within that year.

DIY or Call Us?

Let’s be honest about what’s realistic for a Fort Worth homeowner. A flue liner replacement is not a spring swap on the garage door; it’s working at roof height, sometimes on a 30-foot ladder, pulling a 20-to-35-foot flexible metal tube down a chimney while not chewing up the clay flue liner above the firebox. Gravity, sharp edges, and your balance all work against you. We’ve had to fix DIY attempts where the liner kinked halfway down, the top plate leaked because it wasn’t sealed right, or the wrong alloy was used and rusted out in two years. If you’ve got a single-story ranch with an easy roof pitch and you’re genuinely handy with sheet metal and high work, maybe. For everyone else, call (682) 900-6393 and let us do it with the right gear, the right measurements, and a camera before and after. The labor cost is less than what one trip to urgent care for a ladder fall will set you back.
