Famco Flue Liner Replacement Nationwide

Famco Flue Liner Replacement: The Littleton Owner’s Guide

We stock and install Famco-compatible flue liner replacements throughout Littleton, with typical installed pricing running $1,800 to $3,400 depending on flue height, diameter, and whether the surround masonry needs repair. Most Famco liner jobs we book in Littleton are completed in a single day, and we carry common diameters and flex lengths on our trucks for the Front Range’s most common fireplace configurations. Homeowners usually discover the problem during a sweep when our camera reveals cracked terracotta, corrosion pinholing, or a liner that’s pulled away from the top collar - often after smelling smoke in the house or noticing the fire won’t draft properly on still winter mornings.

Which Famco Models This Applies To

Famco manufactured several liner series over the years, and the replacement strategy depends on which system was originally installed. The Famco flexible stainless series - common in Littleton homes built between 1985 and 2005 - used a proprietary top collar and clamp assembly that differs from current DuraFlex or Olympia Chimney hardware. If your existing liner still has a Famco label near the top termination or stamped on the collar, measure the inner diameter precisely: Famco sold 5.5-inch, 6-inch, and 7-inch rounds for residential wood-burning, plus an 8-inch oval for some factory-built fireplaces. The 5.5-inch size is the compatibility gotcha - it’s not a standard stock item at most Denver-area supply houses, but we keep it on our trucks because we’ve hit it repeatedly in Columbine Knolls and the older Ken Caryl ranch homes.

We are an independent service provider with no affiliation to Famco. When the original Famco part is still available, we’ll quote it. More often, we match a quality aftermarket equivalent from our Haven buying network - typically DuraFlex or Olympia Chimney stainless - that exceeds the original spec and fits the existing top termination with a collar adapter. The decision comes down to what’s in stock, what your flue size demands, and what we can warranty. We won’t know until the camera goes down.

Signs Your Famco Flue Liner Replacement Is Failing

• Smoke spillage into the room on startup. A cracked or separated Famco liner leaks combustion gases before the flue warms and establishes draft. In Littleton’s altitude, where ambient air pressure is already lower, even a small gap at the liner top can cause back-puffing that clears up once the fire gets hot - which makes owners think the problem is technique, not hardware.
• White or orange staining on the exterior masonry. This is acid etching from condensing flue gases reaching the brick through liner gaps. The Front Range’s freeze-thaw cycles accelerate it; we’ve seen spalling brick in Littleton homes where a failed Famco liner went unaddressed for two burning seasons.
• Chunks of clay or metal flakes in the firebox. Older Famco systems used terracotta connectors that degrade, or early stainless that corroded at the welds. If you’re sweeping out debris that isn’t just ash, the liner’s structural layer is coming apart.
• Strong odor even when the fireplace isn’t in use. A breached liner lets creosote odor permeate the house through the chimney chase. Negative pressure in modern tight homes - common in Littleton’s newer construction - pulls that smell right into the living space.
• The sweep’s camera shows gaps, corrosion, or missing sections. This is the definitive sign. Our NFPA 211 Level 2 inspection runs the camera the full flue length; anything less is guessing. Corrine Halstead reviews the footage with you before any quote gets written.

Replacement Cost & What’s Included

What drives the range: flue height (a two-story Littleton home with a tall chase runs more material), diameter (that 5.5-inch Famco odd size costs more to source), and whether the existing top plate or crown needs rework. Every quote we deliver in writing before work starts - Haven Standard Clause 1 - includes the liner spec, labor hours, and warranty terms. No surprises after we’re on your roof. The 365-Day Done Right Promise covers the installation; manufacturer defect coverage runs longer on DuraFlex and Olympia Chimney materials we source through our buying network.

DIY or Call Us?

There’s a safe middle ground here, and then there’s where DIY stops.

What you can check: look up your flue from the firebox with a flashlight for obvious gaps or debris. Note your fireplace model and any Famco labels. Measure the flue opening diameter if you can reach it safely. That’s it.

Where DIY goes wrong: pulling a liner is not like replacing a dryer vent. The old Famco liner may be locked in by creosote buildup, corroded fasteners, or a top termination that’s sealed with high-temp mortar. At height, on a pitched roof, with a heavy flex coil that wants to kink - the injury risk is real, and a damaged liner left partially installed is worse than the original problem because it blocks draft while still leaking. We don’t give step-by-step removal instructions for this part. The camera doesn’t have an opinion - it just shows you what’s there - and neither does a dropped liner section.

Call (720) 439-4666. We’ll scope it, quote it in writing, and handle the roof work with documented photo record on completion - Clause 4 of the Haven Standard, same as we’ve done since 2009.
