Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Famco Flue Liner Replacement: The Quakertown Owner’s Guide
We stock and install Famco-compatible flue liner replacement sections here in Quakertown, and most jobs run between $850 and $1,400 installed depending on the liner diameter, length, and whether we’re doing a straight swap or pulling the whole section. We usually have common sizes on the truck, so same-week scheduling is the norm rather than the exception. Most folks discover the liner has failed the hard way: they notice rust flakes collecting in the firebox, or the damper starts sticking against a warped liner wall, or worse, they smell smoke backing into the house on windy days. The good news is a failed Famco liner section is a known problem with a known fix.
Here’s what you need to know before you spend a dollar: how to identify which Famco liner you have, what actually fails on these units, what a fair installed price looks like in Quakertown, and when the job is genuinely urgent versus a next-season project. No invented problems. If it doesn’t need doing, I’ll tell you that too.
Which Famco Models This Applies To
Famco has made venting and flue components for decades, and around Quakertown we most often see their 4-inch through 8-inch round and oval liners in older masonry chimneys, along with their connector pipe sections on freestanding stoves. If you’re not sure what you have, grab a flashlight and look for the stamped label near the top of the liner section, just under the flue cap. Famco stamps their gauge and diameter right into the metal. If the label is gone, measure the inside diameter of the liner opening: a 6-inch liner measures 6 inches across the throat, not the outside edge. That distinction trips up more DIYers than anything else we see.
Top Hat Chimney is an independent service provider, not affiliated with Famco, which means we can be honest about the OEM-versus-aftermarket decision. For Famco specifically, the OEM liners are solid steel with a good seam weld, but Famco’s real weak point on older installations is the connection joint where the liner meets the stove pipe adapter. That’s where rust and separation happen first. A quality aftermarket section from DuraFlex or Gelco will often outlast the original in a PA climate, because those manufacturers use a slightly heavier gauge and a better seam design. We stock both Famco-compatible replacement sections and the better aftermarket equivalents, and we’ll show you the difference before we order or install anything.
Signs Your Famco Flue Liner Replacement Is Failing
- Rust flakes or a gritty residue in the firebox. Flue liner steel corrodes from the inside out, and what you’re seeing is the inner wall shedding. By the time you see flakes, the liner wall has thinned enough that replacement is the honest call, not patching.
- Smoke smell backing into the living room on windy days. A cracked or separated liner seam lets flue gas escape into the chimney chase instead of venting out the top. Wind pressure pushes it back into the house. This is also how carbon monoxide enters living spaces.
- A damper that suddenly sticks or scrapes. When a liner section warps from repeated heating and cooling cycles, it can distort just enough to pinch the damper plate. If you have to fight the damper handle, have the liner looked at.
- Visible cracks or gaps at the liner joints. Shine a flashlight up the flue with the damper open. If you can see daylight through a seam or notice a joint that’s pulled apart, that section has already failed. No amount of sealant will fix a separated liner joint permanently.
- Chunks of liner material in the cleanout or on the smoke shelf. When a liner degrades to the point of breaking apart, you’ve got a serious draft problem and a fire hazard inside the chimney. Stop burning immediately until it’s inspected and replaced.
Replacement Cost & What’s Included
In Quakertown and the surrounding Bucks County area, a Famco flue liner replacement section typically runs between $850 and $1,400 installed. A straight swap on a common 6-inch round liner with good access might come in at the lower end. An oval liner, a longer run, a difficult roof pitch, or a chimney that needs the crown pulled to access the liner will push toward the upper end.
| What you’re paying for | Typical range |
|---|---|
| Famco-compatible liner section (6-inch round, standard length) | $180-$320 |
| Heavy-duty aftermarket equivalent (DuraFlex or Gelco) | $200-$350 |
| Labor including removal of failed section and proper fitting | $500-$750 |
| Crown seal work if the liner swap requires crown access | $150-$300 |
The price on the phone is the price on the invoice. That’s not a slogan, it’s how Wendell Pike has run Top Hat Chimney since 1999. You’ll get the old liner section back if you want it, and we’ll show you the rust, the cracks, or the separated seam that justified the work. Every job carries our 90-Day Done Right Promise in writing: if the liner installation isn’t right, one call brings us back at no additional cost.
DIY or Call Us?
You can safely do the inspection. Open the damper, shine a flashlight up, and look for rust, cracks, and joint separation. Take photos with your phone. That’s information worth having before you call anyone.
What you should not do is pull a liner section yourself. The liner lives inside a chimney that may have creosote built up on the inner walls, and that creosote is flammable. Removing the liner often means working from the roof, and a wet Bucks County roof in November is no place to learn. If the liner is connected to a gas appliance, you’re also dealing with exhaust that can kill you if it’s not vented correctly afterward. This is a job for a trained professional with proper fall protection and a manometer to verify draft after the install. Call (484) 603-6713 and we’ll get you on the schedule. You’ll get a real arrival window, and if we’re running late, someone calls you.
FAQs
In the Quakertown climate, with its freeze-thaw cycles and humid summers, a properly installed Famco liner typically lasts 15 to 20 years before the steel shows meaningful corrosion. A liner that’s been through chimney fires, or one installed without a proper cap, may fail in half that time. Call (484) 603-6713 if you’re unsure whether yours is near the end.
No, not in a way that lasts. Patching compound and high-temp sealant are temporary measures at best, and they buy you weeks, not years. The steel has already fatigued; the only correct fix is to remove the failed section and install a new one properly seated and sealed.
Most Famco liner swaps take between two and four hours from ladder to ladder. If the crown needs work or the liner is an unusual size, it can run longer, but we’ll tell you that before we start. We’ll also show you the camera footage of the finished install so you can see exactly what you paid for.
We keep the common sizes on the truck: 4-inch, 5-inch, 6-inch, and 8-inch round, plus the oval sections we see most often in older Quakertown chimneys. If we don’t have your size, we can typically have it in hand within a few days. We don’t ask for a deposit to order parts.
