Famco Flue Liner Replacement Nationwide

Famco Flue Liner Replacement: The Chicago Owner’s Guide

Famco flue liner replacement in Chicago typically runs $1,800 to $3,400 installed, depending on chimney height and liner diameter, and we stock the common Famco sizes for same-day installation in most cases. Most homeowners discover the problem during an annual sweep when our camera spots cracked terracotta or corroded stainless, or when they notice water staining on the chimney breast after a hard Chicago freeze-thaw cycle. If your fireplace is smoking back into the room or you smell damp ash on humid summer days, the liner is often the culprit.

Which Famco Models This Applies To

Famco built flue liners across several decades under names that do not always match current catalogs. The most common we encounter in Chicago brick bungalows and two-flats are the Famco stainless flexible liners in 6-inch, 7-inch, and 8-inch diameters, and the older Famco rigid aluminum systems found in 1970s and 1980s construction. The rigid aluminum has largely been discontinued; when it fails, we replace with stainless steel that fits the same footprint but outlasts it.

To identify your liner, check the metal tag at the top of the chimney or the stamped collar where the liner meets the thimble. Famco tags wear, so we also measure inner diameter with a caliper and check the flue’s total length from firebox to crown. OEM Famco replacement parts are available for some newer flexible systems, though we often recommend a quality aftermarket equivalent from our stocked DuraFlex or Olympia Chimney inventory. These match Famco specs exactly, carry the same UL 1777 listing, and install without modifying your existing thimble or cap. One compatibility gotcha: early Famco flex liners used a proprietary beaded connection that does not mate with standard corrugated collars. We carry adapters for this, but it is not something you will find at a supply house.

Signs Your Famco Flue Liner Replacement Is Failing

• Smoke backing up into the room. A cracked or separated Famco liner loses its sealed draft path. Combustion gases spill into living space instead of rising, especially when the wind hits Chicago’s typical west-facing flues.
• Water stains on interior walls near the chimney. Gaps in the liner let condensation reach the brickwork. In our freeze-thaw climate, that moisture expands and migrates through plaster, leaving yellow-brown rings that grow after every rain.
• White efflorescence on the exterior brick. Salts leaching out mean water is getting behind the masonry. A compromised Famco liner is the most common cause in an otherwise sound chimney.
• Strong odor of creosote or damp ash in summer. Without an intact liner, humid Lake Michigan air settles into the flue and reactivates old deposits. The smell is unmistakable once you have noticed it once.
• Chunks of clay or metal in the firebox. Terracotta liners spall; stainless liners corrode at the seams. Either way, debris falling down is a clear signal the system is no longer protecting your home.

Replacement Cost & What’s Included

The range depends on three factors: liner diameter (6-inch runs less than 8-inch), total chimney height (a three-story Rogers Park two-flat versus a single-story bungalow in Garfield Ridge), and whether the existing liner can be pulled or must be cut out in sections. Our estimate includes the Level-2 camera inspection, photos you can see, removal of the failed Famco liner, installation of the new system with proper insulation to prevent condensation, a new rain cap, and cleanup. The 90-Day Done Right Promise covers it all in writing. No arguing. The number on the estimate is the number on the invoice.

DIY or Call Us?

An owner can safely check the rain cap for blockage and shine a flashlight up the flue to spot obvious gaps or debris. That is where safe DIY ends. Flue liner replacement requires working on a steep or high roof, handling heavy stainless sections in a confined space, and properly insulating the annular gap between liner and masonry. A poorly seated liner creates a carbon monoxide path into the home. In Chicago, where chimneys often serve as structural elements in older frame construction, a misstep can damage the breast or surrounding framing. We do not recommend this as a homeowner project. Our technicians carry the common Famco adapter fittings on the truck, complete most replacements in a single visit, and back the work with our written guarantee.
