Famco Flue Liner Replacement Nationwide

Famco Flue Liner Replacement: The Kennesaw Owner’s Guide

We stock and install Famco-compatible flue liner replacement in Kennesaw, typically running $1,800 to $3,400 installed depending on chimney height and liner diameter. Most Famco liner jobs we book are completed in a single day once the written scope is approved. Homeowners usually discover the failure during a routine sweep when the camera catches cracked terracotta, a separated seam, or corrosion pinholes that weren’t visible from the firebox.

Which Famco Models This Applies To

Famco manufactured both rigid stainless and flexible alloy liner systems through the 1990s and 2000s, often sold through HVAC wholesalers in the Atlanta metro. The model designation is stamped on the termination cap or on a tag at the top of the liner itself, not down at the fireplace. Look for series prefixes: FL for flexible, RL for rigid, followed by the diameter and wall thickness (typically .006″ or .010″ for residential). If the tag is corroded off, we measure the inner diameter with a chimney ruler and check the wall gauge with a caliper during the Level 2 inspection.

The OEM Famco liner is no longer in production, so replacement means matching to a compatible alloy from our Haven buying network, typically DuraFlex or Olympia Chimney stainless. We source through this network specifically to keep customer prices honest. For Kennesaw homes built in the 1985-2005 window, especially the two-story colonials near Kennesaw Mountain, we regularly find Famco rigid liners that have shifted at the thimble connection as the chimney settles on clay soil. That settlement pattern is something we account for in the replacement spec.

Signs Your Famco Flue Liner Replacement Is Failing

• White efflorescence or rust streaks on the exterior brick. This means moisture is getting through gaps in the liner and condensing in the masonry. In Kennesaw’s humid subtropical climate, that moisture accelerates freeze-thaw damage every winter even when temperatures barely dip below 32 degrees.
• Smoke or odor seeping into upstairs rooms. A separated Famco liner joint or cracked section lets combustion gases escape the flue path. The smoke chamber above the firebox is the usual leak point on older Famco rigid installations.
• Visible cracks or spalling in the firebox refractory. When the liner fails to contain and vent heat properly, the firebox takes thermal stress it wasn’t designed for. We see this in Kennesaw homes where the original Famco liner was undersized for a converted gas insert.
• Deteriorating mortar joints between flue tiles. On hybrid systems where Famco liner sections meet original terracotta, the joint material degrades faster than either substrate. The camera catches this as a dark ring or gap at the transition point.
• Carbon monoxide detector alerts near the fireplace. Any liner breach can allow CO to back-vent into living space. This is not a troubleshooting moment for the homeowner. Evacuate and call a professional.

Replacement Cost & What’s Included

Chimney height drives most of the variance. A single-story ranch off Wade Green Road runs toward the lower end. A three-story walkout on the slopes near Kennesaw Mountain with a 35-foot flue and offset bends pushes the material and labor higher. We deliver a written price, written scope, and written warranty before anyone starts - Haven Standard Clause 1. The 365-Day Done Right Promise covers the installation. Materials carry manufacturer warranty through our Haven buying network.

DIY or Call Us?

Here’s what you can safely check yourself: confirm the model stamp on the termination cap if you can access it without a ladder, and note any smoke or odor patterns when the system runs. Do not attempt to remove or inspect the liner itself. The old Famco rigid sections are often lodged with creosote and corrosion, and dislodging them without proper anchoring risks dropping material into the smoke chamber or damaging the chimney structure. The replacement liner must be correctly sized to the appliance BTU output and insulated to NFPA 211 standards - a mismatch creates a fire hazard and voids homeowner’s insurance. We write it down before we ask you to decide anything. Call (678) 535-2204 and we’ll get a camera down there first.
