Famco Flue Liner Replacement: The Dallas Owner’s Guide
We stock and install Famco-compatible flue liner replacements throughout Dallas, with most jobs running $850 to $2,400 installed depending on liner diameter, length, and access. Our trucks carry common Famco rigid and flexible liner sections, so in many cases we can complete the swap the same day we diagnose the failure. Most Dallas homeowners discover the problem during a routine sweep, when the brush comes back with flakes of corroded metal, or after noticing a faint rust smell near the fireplace on humid mornings.
If you’ve been told your Famco liner needs replacement, the first thing to know is that you’re not alone. North Texas clay soil holds moisture against chimney exteriors, and Dallas freeze-thaw cycles from November through February put real stress on metal liners. We see it every week in neighborhoods like Lake Highlands, Casa Linda, and Preston Hollow.
Which Famco Models This Applies To
Famco has manufactured flue liners under several product lines over the years, and compatibility comes down to two things: diameter and construction type. The most common units we service in Dallas homes are Famco’s 5.5-inch and 6-inch round rigid liners, their flexible aluminum and stainless flex kits, and older oval liners installed in pre-1990s masonry chimneys.
Here’s the part most homeowners don’t know: a Famco liner from 2008 and a Famco liner from 2019 may look identical at a glance, but the locking collar dimensions changed slightly on some series. We physically measure the existing collar before ordering, because guessing gets expensive. When the original is too corroded to measure cleanly, we match by appliance BTU output and flue diameter rather than by “looks about right.”
On OEM versus aftermarket: for most Dallas installations, a quality aftermarket liner from a manufacturer we trust, like Copperfield or DuraFlex, performs as well as a Famco-branded replacement and often costs $150 to $400 less. That said, if your homeowner’s warranty or appliance manual specifically requires Famco replacement parts, we order straight from Famco and show you the invoice. Alcott Chimney Dallas is an independent service provider, not a Famco dealer or affiliate, so when we tell you an aftermarket part is safe for your setup, it’s because the specs match, not because we get a better margin on it.
Styles & brands we work with





Signs Your Famco Flue Liner Replacement Is Failing
- Flaking metal in the firebox or on the damper. This is the classic early sign. As a Famco liner corrodes, small pieces of oxidized metal break loose and fall. If you see what looks like dark glitter or rust-colored flakes after a fire, the liner wall is thinning from the inside.
- Rust smell on humid mornings. Dallas humidity rises in spring and fall, and a failing liner often gives off a metallic, damp odor when moisture condenses inside the flue. This happens even in the off-season when no fire has burned for weeks.
- Visible rust streaks on the exterior chimney crown or cap. Water gets behind the liner, sits there, and eventually seeps out through masonry joints. Those orange-brown stains aren’t just cosmetic, they mean water is working through your chimney system from some entry point.
- Draft problems that got worse gradually. A corroded liner develops rough interior walls that disrupt the smooth airflow your appliance was designed for. Smoke backs up into the room, the fire won’t hold, or you get a cold draft even with the damper closed.
- Appliance keeps tripping or burning inefficiently. In gas setups, a failing liner can change combustion air mixture. If your gas logs look different, burn more yellow, or the system shuts off unexpectedly, have a flue inspection before assuming the appliance itself is failing.

AfterReplacement Cost & What’s Included
In Dallas, expect a Famco flue liner replacement to land between $850 and $2,400 installed. A straightforward single-story swap with easy roof access and a standard 6-inch liner usually stays under $1,400. Multi-story homes, steep roof pitches common in older East Dallas neighborhoods, or liners requiring demolition of interior chimney chase walls push toward the top of the range and sometimes beyond.
The price you get from us includes the liner, all connectors and termination cap if needed, labor, clean-up, and a written price before any work starts. There are no surprise charges at the end. Our 365-Day Done Right Promise means if the replacement fails within a year, we come back and make it right at no charge. That warranty is written, not verbal, and it’s included on every job, no negotiation required.
| Scope | Typical Dallas Price |
|---|---|
| Single-story, standard 6″ liner, good access | $850 – $1,400 |
| Two-story, moderate access, 7″ – 8″ liner | $1,400 – $1,900 |
| Steep roof, chase demolition, or custom oval | $1,900 – $2,400+ |
DIY or Call Us?
We’ll be straight with you: flue liner replacement is not a DIY job, and the reason isn’t just about difficulty. A liner that isn’t sized correctly, sealed correctly, or connected properly creates a real carbon monoxide risk inside your home. This is combustion exhaust infrastructure. We don’t say that to scare you into hiring us, we say it because proper installation genuinely matters.
What you can safely do on your own is inspect the firebox and damper area for visible flaking or rust, note any unusual smells, and check whether your carbon monoxide detector has a current battery. Those observations help us diagnose faster when you call. But the actual liner swap involves roof work, precise measurement, and knowing how Dallas code applies to your specific appliance and chimney type. That’s what Ruben Castellano and our crew do every day.

FAQs
A properly installed Famco liner in the Dallas climate typically lasts 15 to 25 years, though unlined chimneys venting gas appliances without proper sizing can eat through a liner in under 10. Our local freeze-thaw cycles and summer humidity are the main accelerants, which is why we recommend a camera inspection every couple of years once a liner passes the 12-year mark. Call (361) 264-4483 to schedule an inspection, estimates are free.
Small, localized damage such as a cracked connector or a failed seam can sometimes be repaired with a patch or a resurfacing product like HeatShield, but if the liner is corroding from the inside across a large area, replacement is the honest answer. We’ll show you camera footage of exactly what we found before recommending anything. Call us at (361) 264-4483 and we’ll walk you through what we see.
Most single-story Famco liner replacements in Dallas take 4 to 6 hours, and same-day completion is typical when we have the right liner on the truck. Multi-story homes or jobs needing custom fabrication can run into a second day. We’ll give you a clear time estimate with your written price.
We keep common Famco-compatible rigid and flex liner sizes on the truck, along with DuraFlex, HeatShield, and Gelco products when a different material is the better call for your chimney. If your specific size isn’t on board, we order it and schedule installation as soon as it lands, which in Dallas is usually within a few days.
Tell you what’s there, tell you what it costs, do the work. That’s the whole job.
