Famco Flue Liner Replacement Nationwide

Famco Flue Liner Replacement: The Dallas Owner’s Guide

A Famco flue liner replacement in Dallas typically runs $1,850 to $3,400 installed, depending on the liner diameter, flue height, and whether your existing Famco components are still sound enough to reuse. We stock Famco-compatible stainless liners on our trucks and can usually complete the swap in a single visit. Most Dallas homeowners discover the problem the hard way: a chimney inspection flags corrosion, or they notice flaking metal pieces in the firebox below the flue. If you’re seeing rust scale, a disconnected liner section, or water staining around the chimney chase, that’s the part telling you it’s done.

Flint Chimney Co Dallas is an independent chimney service company. We are not affiliated with Famco, but we work with their product line regularly and know how their specs run.

Which Famco Models This Applies To

Famco manufactures rigid and flexible stainless steel chimney liners in diameters from 4 inches up to 12 inches, sold through distributors to chimney professionals across Texas. The liner you have is stamped with its diameter and alloy grade along the outer wall, usually within the first three feet from the top. That stamp is what our crew reads first when we’re matching a replacement. If the stamp is corroded away, we measure the inner diameter with a caliper and match it to the nearest Famco-compatible size.

The key compatibility gotcha with Famco liners is the connection system. Famco uses a male-female slip joint that locks with a stainless retaining band, and the joint must face the correct direction: the male end points downstream, toward the appliance, never toward the top. If a previous contractor installed the section backward, exhaust turbulence and creosote accumulation happen at the joint, which is exactly where Famco liners fail first. We see this in Dallas homes with older installations, where a handyman or a homeowner did the liner themselves.

For the OEM-versus-aftermarket decision: the honest answer is that Famco makes a solid liner, but so do a few other manufacturers, and what actually matters is the alloy. We default to the same 316L stainless Famco specifies for wood-burning applications in North Texas, where high humidity and sulfur-heavy creosote eat lesser grades faster. If your appliance is gas only, a 430 grade is acceptable and costs less. We’ll tell you which one fits your actual setup, not which one pads a ticket.

Signs Your Famco Flue Liner Replacement Is Failing

• Rust flakes or metallic debris in the firebox. This means the inner wall of the liner is corroding and shedding material. On a Famco liner, that usually starts at a welded seam or a slip joint that’s been installed backward. The liner is no longer smooth, so creosote builds faster, which accelerates the corrosion in a loop.
• Water staining on the ceiling or wall near the chimney chase. A failed liner lets flue gas condense inside the chimney cavity instead of venting out. That condensation carries acidic creosote, which eats the mortar and leaks into framing. In Dallas, our freeze-thaw cycle turns that moisture into expansion damage inside the chase every winter.
• A smell like an ashtray in the room even when the fireplace is cold. That’s exhaust backdrafting through a cracked or disconnected liner section. It means combustion products are finding a path into your house instead of up the flue. It’s not just unpleasant; it’s the first warning sign of a carbon monoxide problem.
• Visible gaps or separation at a slip joint during an inspection. Famco sections can pull apart if the retaining band was never torqued correctly or if the liner shifted during a violent storm. A separated joint dumps heat and gas into the chimney cavity, and any combustible material nearby becomes a fire risk.
• A liner that’s more than 15 years old and lives in an exterior chase. Dallas humidity, combined with the repeated heating and cooling cycles of a fireplace, shortens a liner’s lifespan compared to an interior flue. The old-timers in the trade will tell you a liner “lasts 20 years” but in our experience across Dallas, including older homes near the M Streets where decorative fireplaces get heavy seasonal use, 15 years on an exterior chase is the realistic ceiling.

Replacement Cost & What’s Included

Here’s the pricing picture for a Famco flue liner replacement in Dallas:

• Liner material only (4-6 inch diameter, per linear foot): $38 to $65
• Liner material only (7-8 inch diameter, per linear foot): $55 to $90
• Typical installed replacement, single story, 15-20 foot flue: $1,850 to $2,600
• Typical installed replacement, two story or steep roof access: $2,400 to $3,400
• Removal and disposal of the old liner: included in the installed price

What moves the price is access. A single-story ranch in Garland with a straight flue and easy ladder setup is the bottom of that range. A two-story in Lakewood with a steep pitch and a chimney cap that needs replacing at the same time lands at the top. We don’t layer on surprise fees. The number we write on your estimate before any work starts is the number on the invoice. Every replacement carries our 365-Day Done Right Promise in writing: if the liner fails within a year, we return and fix it at no charge, no argument.

DIY or Call Us?

What you can safely do yourself: check the firebox for rust flakes, shine a flashlight up from below to see if the liner walls look smooth or pitted, and look for water stains around the chase. You can also check the stamp on the liner if you have a rooftop access and a proper ladder, but that’s where we’d draw the line. A flue liner replacement means working at height, often on a pitched roof, while maneuvering a 20-foot section of stainless steel. If you drop a liner section down the flue, you’re now removing it from inside, which is a worse job than the original replacement. And if the liner is disconnected or corroded through, you’re dealing with the possibility of carbon monoxide backdrafting while the system is open.

We’ll match your Famco liner, replace it, and stand behind the work for a year. If the flue’s clear, we’ll tell you. If it’s not, we’ll show you exactly why. Call us at (361) 492-4099 and we’ll put a number in writing.
