Famco Flue Liner Replacement Nationwide

Famco Flue Liner Replacement: The Huntington Owner’s Guide

Famco flue liner replacement in Huntington typically runs $1,800 to $3,400 installed, depending on chimney height, diameter, and whether the existing liner is stainless or aluminized. We stock Famco-compatible stainless steel liners in 6″, 7″, and 8″ diameters for same-day installation on most Huntington homes. Most owners discover the problem mid-season, when a smoky fireplace or a Level-2 inspection reveals cracks, corrosion spots, or separation at the collar that weren’t visible from below.

Which Famco Models This Applies To

Famco built flue liners across several series from the early 1980s through the mid-2000s, and the compatibility question matters more than most homeowners realize. The round flexible stainless liners marked “Famco” typically carry a stamped model prefix: FL for flexible round, RL for rigid, and the less common DL double-wall series used in some 1970s Huntington split-levels with exterior chimneys. Check the top collar or the metal tag at the cleanout - if it’s worn, measure the inner diameter with a tape measure and note whether the chimney is straight or has offsets.

We carry OEM-grade Famco-compatible replacements from Olympia Chimney and Copperfield, plus DuraFlex when the application calls for higher-grade 316Ti stainless. Aftermarket equivalents often outperform original Famco aluminized liners, which were rated for 15-20 years and are now well past that in most Huntington homes we inspect. The gotcha: some early Famco rigid liners used a proprietary 7.5″ diameter that doesn’t map cleanly to modern standard sizes. We’ve run into this twice on West Neck Road homes built in 1986 - in those cases, we custom-order from Olympia Chimney rather than force a poor fit.

Signs Your Famco Flue Liner Replacement Is Failing

• Smoke backing up into the room. A separated or cracked Famco liner loses its draft seal, especially on cold starts when the flue needs to warm quickly. In Huntington’s coastal climate, morning fog and damp air make a compromised liner even slower to establish draft.
• White or orange staining on exterior masonry. Condensation carrying creosote and acids leaches through mortar joints when the liner no longer contains combustion gases. We see this pattern often on north-facing chimneys in Huntington Bay, where freeze-thaw cycles accelerate the damage.
• Chunks of clay or metal debris in the firebox. If your chimney was originally clay-lined and later retrofitted with a Famco liner, deteriorating clay can collapse onto the metal insert. The liner then carries double the load it was sized for.
• Carbon monoxide detector alerts. Even low-level leaks from a perforated liner are worth taking seriously. A Level-2 camera inspection will show pinholes or seam separation that a standard sweep from below cannot catch.
• Visible corrosion or holes at the liner top. The Famco collar and upper section take the worst of acidic condensation. In salt-air exposure near Huntington Harbor, we’ve seen 316 stainless show surface pitting in under 12 years - aluminized steel fails faster.

Replacement Cost & What’s Included

What drives the range: chimney height, whether we need to remove a damaged existing liner first, and if the top plate or rain cap also needs replacement. Every estimate includes the Level-2 camera inspection, photos you can see, and a plain-English verdict before any work begins. The price we quote is the price on the invoice - no surprises. Our 90-Day Done Right Promise covers the installation in writing, no arguing. Hearthstone Chimney Co. is an independent service provider; we are not affiliated with Famco.

DIY or Call Us?

There’s a short list of things a Huntington homeowner can safely check: confirm the damper opens fully, verify the chimney cap isn’t clogged with debris, and listen for unusual draft sounds when the fire is lit. Beyond that, flue liner replacement involves working at height on a steep roof, handling sharp stainless edges, and properly sizing draft for your specific appliance - a mismatch here creates a carbon monoxide hazard that won’t announce itself until it’s serious.

We’ve been called to fix DIY liner installations where the diameter was wrong by half an inch, or where the liner wasn’t properly anchored at the top and slid down within a season. The cost to correct those mistakes usually exceeds what professional installation would have run originally. If your Famco liner is showing any of the symptoms above, call (631) 776-4075 - we’ll inspect it properly and give you a number you can plan around.
