Famco Flue Liner Replacement Nationwide

Famco Flue Liner Replacement: The Leesburg Owner’s Guide

We stock and install Famco-compatible flue liner replacement in Leesburg, with most jobs running $1,800 to $3,400 installed depending on height, diameter, and whether the existing liner pulls out clean. In our experience across Loudoun County, we can usually source correct Famco sizing same-day and complete the swap in a single visit. Most homeowners in Leesburg discover the problem mid-winter: a smoky fireplace, a hot exterior wall, or a neighbor mentioning their chimney looks wrong.

Which Famco Models This Applies To

Famco built flue liners in several series over the decades, and the compatibility rules are not forgiving. The stamped model tag, usually found on the top termination cap or collar, will read something like FL-6, FL-8, or a variant with a year suffix. We need the diameter to the quarter-inch and the total run from appliance throat to cap, because Famco’s older aluminum liners (pre-2005) do not mate with current stainless specs without a custom transition.

Here’s the gotcha we see in Leesburg’s older stock, especially the colonials near Morven Park: Famco used a proprietary collar depth on their 1980s and early 1990s flex liners. A generic aftermarket collar will seat, but it leaves a gap that collects creosote. We keep both OEM-pattern Famco collars and machined adapters on the truck for exactly this reason. For most Leesburg homes with a standard 6-inch or 8-inch run, a quality 316Ti stainless aftermarket liner from our inventory outlasts the original aluminum by a wide margin, and we price both options upfront so you choose.

Signs Your Famco Flue Liner Replacement Is Failing

• Smoke spilling into the room on startup. A breached Famco liner, often at a seam or elbow, loses the draft pressure that carries smoke upward. In Leesburg’s older two-story homes, this shows up first on the first fireplace when a second flue is pulling air.
• Hot masonry or siding near the chimney chase. When the liner’s insulation blanket degrades or the wall itself thins, heat radiates outward. We’ve measured exterior surface temperatures above 180 degrees on failed Famco runs in Loudoun County.
• White or orange staining on the chimney exterior. This is acid condensation eating through a compromised liner and leaching salts through the mortar. It means the liner is no longer protecting the masonry.
• Chunks of clay or metal in the firebox. Famco’s early flex liners can fatigue at stress points, especially where a chimney offsets around a framing member. What falls down has already failed.
• Carbon monoxide detector alerts near the hearth. A liner with gaps or collapse can reverse draft under certain pressure conditions. This is not a nuisance call. This is the one that demands immediate inspection.

Replacement Cost & What’s Included

What moves the number: height adds material and rigging time; offsets require more labor than a straight drop; and if the existing Famco liner has corroded in place, extraction takes longer than a clean pull. We quote the full installed price before we start, including the new liner, proper insulation pack, termination cap, and sealing. The 90-Day Done Right Promise covers the work in writing. No arguing, no paperwork chase.

DIY or Call Us?

A homeowner can safely check the model tag location and measure the flue opening with a tape measure. Do not climb the roof to inspect the cap yourself. The liner runs through a confined, high-temperature space, and a dropped section can block the flue entirely or damage the chimney structure. In Leesburg, we’ve been called after a well-meaning owner wedged a mismatched section that jammed two feet down and cracked the clay thimble.

The actual replacement requires proper sizing, insulation calculation, and a camera-verified seal at both ends. We carry Famco-compatible diameters from 5-inch to 10-inch on the truck, and our technicians are background-checked, uniformed, and equipped to complete most liner replacements in a single visit. Call (571) 701-7519 and we’ll talk through what you’re seeing.
