Famco Flue Liner Replacement Nationwide

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

We stock and install Famco-compatible flue liner replacement in Fort Worth, with typical installed pricing running $1,800-$3,400 for most residential chimneys depending on height, diameter, and whether the liner is rigid or flexible. Most Famco liner jobs we book in Fort Worth are completed in a single day once the inspection confirms the spec. You’ll usually discover the failure during a sweep when the camera turns up gaps, corrosion scaling, or clay tile fragments in the smoke chamber - or when you notice drafting problems and that faint smoke smell on humid afternoons.

Which Famco Models This Applies To

Famco manufactures several liner series, and the replacement part you need depends on what’s currently in your flue. The most common we encounter in Fort Worth homes are the Famco flexible stainless liners in 316Ti alloy (the standard for wood-burning) and the heavier 316L rigid liners found in some pre-2000 installations. Check the collar plate at the top of the chimney; Famco stamps the alloy grade and nominal diameter there. If the plate’s corroded off, we measure the flue interior directly - a 6-inch round clay flue typically takes a 5.5-inch flexible liner, while an 8×12 rectangle usually needs a 6.5-inch ovalized flexible or custom rigid solution.

Here’s where owners get tripped up: Famco’s older “Universal Fit” series from the early 2000s used a proprietary top-seal gasket that’s no longer manufactured OEM. We source compatible aftermarket seals through our Haven buying network that mate correctly and cost roughly 40% less than hunting down NOS (new old stock) Famco originals. For the 316Ti flexible lines still in production, we can match OEM spec exactly. Corrine Halstead makes the call on-site after the camera inspection - the camera doesn’t lie, and neither does the written estimate.

Signs Your Famco Flue Liner Replacement Is Failing

• Draft reversal on still days. When the Famco liner develops gaps or the flex sections separate, combustion gases lose the suction they need. You’ll notice smoke lingering in the firebox or that eye-watering bite of carbon monoxide pushing back into the room when the wind drops, especially common in Fort Worth’s calm summer mornings.
• White efflorescence or rust streaks on the exterior brick. Moisture and acidic condensate are migrating through liner breaches, leaching salts from the mortar and carrying iron oxide down the chimney face. This means the liner’s protective barrier is compromised and the masonry is taking damage.
• Chunks of clay or metal flakes in the firebox after sweeping. If your original chimney was clay-lined and the Famco retrofit is failing, you’re seeing the old clay collapse through the new liner’s gaps. Metal flakes suggest 316Ti corrosion at the flex joints - accelerated in Texas by temperature swings from 30°F winter nights to 80°F afternoons.
• Hot spots on surrounding walls or a discolored chimney breast. A breached liner radiates heat directly into framing and lath. We’ve found this in Fort Worth’s 1920s Craftsman homes near Mistletoe Heights where the original construction tucked chimneys tight to interior walls.
• Your carbon monoxide detector chirps during fireplace use. This is not a false alarm. A failing liner can vent exhaust into wall cavities instead of up the flue. Evacuate and call a professional - this is the symptom that tolerates no waiting.

Replacement Cost & What’s Included

What drives the range: chimney height (two-story Colonial vs. single-story ranch), whether we can pull flex without demolishing the existing liner, and if the top-seal or thimble connection needs reworking. Every quote we deliver in Fort Worth is written, itemized, and signed before work starts - Haven Standard Clause 1. The 365-Day Done Right Promise covers the installation, and we document the completed flue with camera footage and photos under Haven Standard Clause 4, same as we’ve done since 2009.

DIY or Call Us?

There’s a safe middle ground and a hard stop. You can verify the collar plate stamping, measure your flue’s interior dimensions with a tape, and check for visible rust streaks from ground level with binoculars. What you cannot safely do: pull a liner through a two-story flue (the torque on the pull rope can snap a section and drop it), work on a steep roof without proper tie-off, or properly evaluate whether the liner failure has damaged surrounding masonry. The 316Ti flex sections are sharp when cut, and a dropped section in a lined flue becomes an expensive extraction. We’re not going to pretend this is rocket science, but we’ve been called to enough Fort Worth homes where the DIY pull went wrong to know it costs more to fix than to book right. Call (682) 499-2712 and we’ll scope it, price it, and handle it.
