Famco Flue Liner Replacement Nationwide

Famco Flue Liner Replacement: The Phoenixville Owner’s Guide

We stock and install Famco-compatible flue liner replacement in Phoenixville, with typical installed pricing running $1,850-$3,400 depending on liner diameter, height of the stack, and whether the existing liner is stainless or clay tile. Most Famco flue liner jobs in the Phoenixville area are completed in a single day once the written scope is approved, and we carry the common diameters on our trucks. Homeowners usually discover the failure during a routine sweep when the camera reveals cracked clay tiles, separated stainless joints, or corrosion pinholing near the top of the stack where condensation collects worst.

Which Famco Models This Applies To

Famco flue liners were installed across several product lines common in Chester County homes built between 1985 and 2010. The most frequent we encounter are the Famco 316L stainless flexible liners in 6-inch and 8-inch diameters, and the earlier Famco rigid clay-aluminum composite systems used in masonry chimneys throughout the Phoenixville and Valley Forge corridor. The critical identifier is the stamped collar band at the top termination, which carries a model prefix: FLX for flexible, RIG for rigid, and a two-digit year code.

Here’s where owners get tripped up. Famco’s FLX-06 and FLX-08 flexible liners use a proprietary collar depth, 2.25 inches, that doesn’t seat cleanly in standard top plates from DuraFlex or Olympia without a field-fabricated adapter. We source the correct Famco termination hardware through Haven’s buying network, or we machine-match an aftermarket equivalent on-site when the OEM part is discontinued. For rigid systems, the RIG-06 clay-aluminum composite is no longer manufactured, and we replace with a 316L flexible liner of equal or greater diameter per NFPA 211 standards, with a documented photo record of the new liner pulled and seated.

Aftermarket equivalents from Gelco and HeatShield meet the same 316L spec and carry comparable warranties, but collar compatibility is the make-or-break detail. We measure before we quote.

Signs Your Famco Flue Liner Replacement Is Failing

• White efflorescence or rust streaking on the exterior brick means moisture is getting past the liner somewhere in the stack. In Phoenixville’s freeze-thaw cycle, that water expands, widens cracks, and compromises the liner’s seal within two to three winters.
• Bits of clay tile in the firebox or cleanout door indicate the original Famco rigid liner is spalling, usually from thermal shock or acid corrosion. Once tiles start dropping, the liner is no longer containing combustion gases as designed.
• Smoke drafting back into the room on startup points to a separated flexible liner joint or a partial collapse that narrowed the flue diameter. The camera finds it within the first ten feet, almost every time.
• A persistent tar or creosote odor even when the fireplace is cold suggests gaps in the liner are allowing creosote to accumulate in the chimney cavity between the liner and masonry. That’s a chimney fire risk, and it’s more common in the older Famco RIG systems we see near the Schuylkill River trail corridor where homeowners burn seasoned hardwood less consistently.
• Visible corrosion or pinholes when looking up from the firebox means the stainless liner has reached end of life, typically 15-20 years in Pennsylvania’s humid summers and acidic condensation environment. The camera confirms the extent; replacement follows if the holes are through-wall.

Replacement Cost & What’s Included

The range depends on three factors we document before quoting: liner diameter and length, whether the existing liner pulls cleanly or requires demolition, and whether the smoke chamber needs parging to meet current NFPA 211 clearances. Every quote is delivered in writing before work starts, per Haven Standard Clause 1, with the written warranty and the documented photo record specified upfront. Materials come through Haven’s buying network from Famco, DuraFlex, HeatShield, Gelco, and other certified suppliers. The 365-Day Done Right Promise covers the installation.

DIY or Call Us?

There’s a safe middle ground, and then there’s the roof.

A homeowner can verify the model number from the top termination collar, check the cleanout for debris or tile fragments, and confirm the damper opens fully. What you cannot safely do is pull a liner from a two-story stack, work with high-tension chimney caps in wind, or evaluate whether a hairline crack in clay tile is superficial or through-wall. The camera doesn’t negotiate - Corrine Halstead shows customers the footage before quoting a single dollar, and that footage is what separates a $200 sweep from a $2,800 liner replacement you can actually see the need for.

If you’re comfortable on a ladder and want to photograph the collar stamp, we’ll identify the part by text. For the pull and seat, call (610) 321-5157. We’re independently operated and not affiliated with Famco, but we stock the common diameters and machine-match terminations when needed.
