Famco Flue Liner Replacement: The Pottstown Owner’s Guide

Famco flue liner replacement in Pottstown typically runs $1,800-$3,400 installed, depending on chimney height and whether the liner is rigid or flexible stainless steel. We stock Famco-compatible liners and connectors for most residential models, and most replacements are completed in a single visit. If you’re smelling smoke in the house, seeing rust flakes in the firebox, or your draft has gone weak since last burning season, the liner is the first thing to check.

Most Pottstown homeowners discover the problem during their first fire of the season. The chimney looks fine from the street. But a Level-2 camera inspection reveals the truth: pinholes, separated seams, or scaling that started three winters back and finally broke through. The chimney does not lie - and neither do we.

Which Famco Models This Applies To

Famco manufactured several liner series over the years, and the right replacement depends on what is currently in your flue. The most common we encounter in Pottstown homes are the Famco flexible stainless liners (typically 316Ti alloy, .006 to .012 wall thickness) and the older rigid 304 stainless systems installed from the late 1980s through the mid-2000s. Check the collar plate at the top of the chimney or the connector band below the cap for a stamped model prefix - FLX, RGD, or UL-1777 markings are typical.

Here is where owners get tripped up. Famco’s flexible liners in the 6-inch and 8-inch diameters used slightly different end fittings depending on whether the original was sold as a kit (with appliance adapter) or as liner-only. The adapter collar on a kit liner measures 13/16 inch at the male end; liner-only units run 7/8 inch. Mix them and you will have a gap that leaks combustion gases. We measure before we order. We also match alloy grade to application: 316Ti for wood and coal, 304 for gas-only venting. Using 304 with wood in a Pottstown winter where freeze-thaw cycles accelerate corrosion is a shortcut that costs more later.

We are an independent service provider - not affiliated with Famco - so we source both OEM Famco replacement sections and quality aftermarket equivalents from Olympia Chimney and Copperfield when the original spec has been discontinued. The aftermarket route saves roughly 15-20% on parts with no drop in performance, provided the alloy and wall thickness match.

Signs Your Famco Flue Liner Replacement Is Failing

• Smoke smell on upper floors when the fireplace is running. This usually means pinholes or seam separation in the liner body, letting combustion gases leak into the chimney cavity and migrate through gaps in the framing. In Pottstown’s older homes near Manatawny Street, we see this where original clay liners were retrofitted with Famco flexible inserts that settled or corrugated over time.
• Rust-colored flakes or powder in the firebox. Stainless steel does not rust, but the connector bands, storm collars, and top plates are often galvanized or lower-grade metal. When those corrode, the debris falls down the flue. It is a warning that water is getting in, and the liner itself is next if the cap or flashing is not addressed.
• Draft that worked fine last year now needs the door cracked open. A liner with interior scaling or creosote buildup loses its smooth bore, and the friction kills draw. Flexible liners are especially prone if they were not properly supported and have developed low spots where moisture and creosote pool.
• Visible gaps or sagging at the chimney top. Famco flexible liners rely on proper tensioning at the top plate. If the draw band has loosened or the support plate has corroded, the liner can drop several inches, breaking the seal at the appliance adapter below. This is not a repair; it is a replacement situation.
• Your home inspector flagged it, but you are not sure how urgent it is. This is the most common call we get. The answer depends on what the camera shows. A thin spot in one quadrant can be monitored. A through-wall hole at the smoke chamber is a carbon monoxide risk and needs immediate attention.

Replacement Cost & What’s Included

For Pottstown homes, Famco flue liner replacement breaks down as follows:

What moves the number: chimney height above the roofline (two-story colonials in Pottstown’s historic districts run taller), whether the existing liner can be pulled or has to be cut out in sections, and if the appliance adapter needs replacement too. We price this upfront. The number on the estimate is the number on the invoice. Every replacement includes our Level-2 camera inspection before and after, photos you keep, and the 90-Day Done Right Promise in writing. If it is not right, we come back. No paperwork, no arguing.

DIY or Call Us?

There is a safe middle ground here, and then there is the point where you stop.

What you can check safely: look up the flue from the firebox with a flashlight for obvious gaps, rust debris, or daylight showing where the liner should be continuous. Check the exterior cap and collar for corrosion or looseness. Note your model number if you can read it. That information saves time when you call.

Where DIY goes wrong: pulling a liner is not like replacing a dryer vent. The old liner may be creosote-heavy and brittle. The new one must be measured precisely, supported at the correct tension, and sealed to a code-compliant termination. More critically, working on a chimney top in Pottstown’s freeze-thaw season means dealing with steep pitches, often on homes built before 1940 with slate or irregular tile. The fall risk is real, and the consequence of a liner installed with a hidden gap is carbon monoxide in the living space. We have re-done enough homeowner and handyman installations that we will say it plainly: this is not the place to learn on the job.
