Famco Flue Liner Replacement Nationwide

Famco Flue Liner Replacement: The Falls Church Owner’s Guide

We stock and install Famco-compatible flue liner replacement in Falls Church, with most jobs running $2,800-$4,500 installed depending on liner diameter, chimney height, and whether the existing liner is stainless or clay tile. Our trucks carry Famco-spec 316Ti stainless and 304 alloy liners in common diameters from 5 to 8 inches, so we can often measure, match, and install without a second trip. Most homeowners discover the problem mid-season: a smoky fireplace, water stains on the firebox wall, or a chimney sweep’s camera showing gaps or corrosion they did not know were there.

Which Famco Models This Applies To

Famco built flue liners across several product lines over the years, and the label location tells most of the story. Look for a stamped metal tag near the top termination or a printed band on the liner itself - model prefixes like FL-, FSL-, or FDL- indicate the series, with the number following it giving the nominal diameter in inches. The FL-600 and FL-800 series are the most common we encounter in Falls Church’s 1960s and 1970s split-levels, particularly in the neighborhoods off Broad Street and around the West Falls Church Metro corridor where those construction eras cluster.

OEM Famco liners are no longer manufactured, which is where the aftermarket decision comes in. We source replacement liners from Famco-compatible 316Ti stainless stock that matches or exceeds the original wall thickness - typically .005 to .007 inch for residential duty. The critical spec is not the brand name on the box but the alloy grade, wall thickness, and whether the liner is listed to UL 1777. A thinner 304 alloy will cost less upfront and fail faster in the wet-freeze cycles we get in Northern Virginia. We use 316Ti for anything passing through an unlined masonry chimney in Falls Church because the salt and acid resistance matters over decades, not just seasons.

Signs Your Famco Flue Liner Replacement Is Failing

• Smoke backing up into the room on startup. A compromised liner loses its sealed flue path, especially where joints have separated or the metal has corroded through. In Falls Church’s older homes with original Famco installations, we often find the top joint has worked loose after thirty-plus years of thermal expansion.
• Water staining or rust on the firebox floor or damper. A liner with pinholes or failed seams allows condensation and rain to reach the masonry surround. The clay flue tiles beneath a failed metal liner act like a sponge, and by the time you see rust, the damage has been happening for multiple burn seasons.
• White efflorescence or spalling brick on the exterior chimney. This means moisture is migrating through the masonry, and a breached liner is the most common culprit in an otherwise sound chimney. We see this frequently on the north-facing sides of chimneys in Falls Church, where freeze-thaw cycles are most aggressive.
• Strong odor of creosote even when the fireplace is cold. A liner with gaps allows creosote-laden air to leak into the chimney cavity, where it saturates the masonry and off-gases into the house. The smell is not just unpleasant - it signals that the flue gas containment has failed.
• A Level-2 inspection reveals gaps, corrosion, or missing sections on camera. This is the definitive finding. Our camera shows what the eye cannot, and with Famco liners, we typically find corrosion beginning at the lower third of the liner where acidic condensation collects and at any joint that was not properly sealed during original installation.

Replacement Cost & What’s Included

For a typical Falls Church single-family home with one fireplace and a chimney height of 18 to 25 feet, Famco flue liner replacement runs $2,800-$4,500. The lower end applies to a straight run with good access, 5- or 6-inch diameter, and no masonry repair needed. The upper end covers 8-inch diameter, offset bends, a taller chimney, or the need to rebuild the top course of brick before setting the new termination.

Every quote includes the liner itself, insulation wrap where required by code, a new top plate and rain cap, removal and disposal of the old liner, and our Level-2 camera inspection with photos you receive. We price upfront - the number on the estimate is the number on the invoice. The work is covered by our 90-Day Done Right Promise in writing, no arguing. If it is not right, we come back.

DIY or Call Us?

There is honest work a homeowner can do here, and there is work that belongs to a trained crew. You can verify your model number, check the firebox for visible rust, and listen for the telltale whistle of a leaking joint when the fire first draws. What you should not attempt is liner extraction or installation. A failed Famco liner may be lodged with creosote, pinned by shifted masonry, or running through a chimney with compromised structural integrity. The replacement liner must be measured precisely, dropped without kinking, and connected to an appliance collar or thimble with proper clearances to combustibles. Falls Church follows the Fairfax County amended IRC - specific clearance rules apply, and an uninspected installation can void your homeowner’s insurance. We are not affiliated with Famco; we are an independent service provider with the tools and training to do this safely. Call (571) 489-4365 and we will walk through what you are seeing before we schedule anything.
