Famco Flue Liner Replacement Nationwide

Famco Flue Liner Replacement: The Denton Owner’s Guide

Famco flue liner replacement in Denton typically runs $1,800-$3,400 installed, depending on liner diameter, height, and whether the existing liner is stainless or terracotta. We stock Famco-compatible liners in 6″, 7″, and 8″ diameters on our trucks, and most replacements are completed in a single day. The camera doesn’t guess - and neither do I.

Most Denton homeowners discover their Famco liner is shot during a routine sweep, not because they noticed smoke in the living room. The tell is usually a cracked terracotta flue tile spotted on camera, or a stainless liner with visible corrosion at the collar where condensation pools. In the older homes near the historic Denton Square, we see this more often than you’d think - those wood-burning fireplaces worked hard through the 2019 and 2021 ice storms, and the thermal cycling takes a toll.

Which Famco Models This Applies To

Famco manufactures flue liners and chimney components across several product lines, but the replacement part you need depends on what was originally installed. Famco’s stainless flexible liners - the SL series and the heavier-gauge SL-HD - carry a part number stamped on the top collar near the flue top. If that label is corroded off, we measure inner diameter and wall thickness with a caliper: .005″ indicates standard SL, .010″ indicates SL-HD. The collar style matters too - Famco’s clamp-ring connection differs from DuraFlex’s snap-lock, and mixing the two creates a leak path.

We source Famco-compatible replacement liners through Haven’s buying network, along with DuraFlex, HeatShield, and Gelco alternatives. For most Denton installations, a quality aftermarket stainless liner meeting UL 1777 performs identically to OEM Famco at a lower material cost. The exception is factory-built fireplace systems where the listing requires exact OEM components - we’ll tell you if that’s your situation after the camera inspection, not after we’ve started cutting.

Signs Your Famco Flue Liner Replacement Is Failing

• White efflorescence or rust staining on the exterior brick. This means moisture is getting through cracks in the liner and leaching salts from the masonry. In Denton’s clay-heavy soils, that moisture accelerates spalling on the chimney’s exterior face.
• Flakes of terracotta in the firebox or cleanout door. Those shards came from the liner itself. Once tiles start shedding material, the liner’s ability to contain heat and combustion gases is compromised.
• Smoke smell in upstairs rooms when the fireplace isn’t running. A cracked liner creates a reverse draft path. Warm air from the house rises through gaps and carries soot odor with it - common in Denton’s two-story ranch builds from the 1980s.
• Visible gaps or shifting in the liner joints on camera inspection. Famco’s terracotta tile systems rely on tight mortar joints. Settlement in North Texas expansive soils opens these joints over 15-20 years.
• Difficulty starting or maintaining a fire despite dry wood and open damper. A partially collapsed liner chokes airflow. We see this when a stainless liner has detached at the collar and sagged into the flue path.

Replacement Cost & What’s Included

What drives the range: liner diameter and length, whether we can pull the new liner through the existing flue or must remove terracotta first, and whether the chimney top needs a new crown or chase cover for proper termination. Every quote is written and itemized before work starts - Haven Standard Clause 1. The liner carries a lifetime warranty; our workmanship is covered by the 365-Day Done Right Promise. Photos and camera footage are archived under Haven Standard Clause 4, same as every job since 2009.

DIY or Call Us?

There’s a safe middle ground and a hard stop. A homeowner can verify the liner part number from the collar label, measure flue diameter with a tape, and check the cleanout door for debris - that’s it. Everything past that point involves working on a roof, handling sharp stainless edges, and properly sizing combustion air supply. A liner installed too small chokes the appliance; too large, and creosote condenses on the walls. The connection at the appliance collar must be sealed to NFPA 211 standards - a gap there vents carbon monoxide into the chase.

We’ve replaced Famco liners in Denton homes where the previous owner tried a self-install and missed the clearance to combustibles by three inches. That house was one ember away from a structure fire. If you’re not certain of the chase dimensions and the appliance listing, call us at (940) 373-6912. The inspection is free, and you’ll have a written price before anyone touches a tool.
