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 Chimney Liner & Rebuild in Allentown: What to Know First
We provide independent Famco chimney liner and rebuild service across Allentown, with most liner replacements and partial rebuilds completed in a single visit and priced upfront before we start. As an independent Famco service provider, we carry no manufacturer obligations, which means we recommend only what your chimney actually needs based on camera evidence you can see for yourself. Typical turnaround from call to completion runs three to five days during peak burning season, faster when weather permits. If you own a Famco liner system in a Center City rowhome, a West End twin, or one of the larger colonials near Trexler Park, this page covers what fails, what it costs, and how we handle it. Call (610) 632-1394 to speak with a live person and book your free estimate.
How Famco Products Fail - and How We Fix Them
- Famco 316Ti flexible liner series: creosote buildup at corrugated joints. The corrugations that make these liners flexible also create low spots where creosote cakes up faster than on smooth-wall competitors. In Allentown’s cold, wet shoulder seasons, homeowners run short, smoldering fires that accelerate the problem. We remove the liner when accessible, rotary-clean the joints with a custom brush head, or recommend replacement with a smooth-wall DuraFlex or Gelco equivalent if the buildup has caused thinning or pitting.
- Famco rigid stainless tee assemblies: weld-seam separation at the collar. The tee body where the liner meets the thimble collar carries thermal stress every firing cycle. We’ve found this especially in Famco tees installed during the 2008-2014 period, when batch consistency varied. Our fix is to cut out the failed tee, inspect the surrounding masonry for heat damage, and install a new tee with an extended collar and proper refractory packing, not just sealant.
- Famco top-mount damper and liner cap combinations: cap rust-through at the mesh skirt. Allentown’s freeze-thaw cycles and road-salt aerosol from I-78 and Route 22 accelerate corrosion at the mesh-to-frame joint. Water then runs down the liner, staining the fireplace face and rusting the liner top. We replace with a Gelco or Copperfield cap with a heavier-gauge skirt and proper overhang, and we check the liner crown for cracks while we’re up there.
- Famco oval-to-round adapters in older Allentown flues: collapse or ovalization under thermal load. Many West Park and Jordan Park homes have narrow, rectangular terra cotta flues that were retrofitted with Famco oval adapters. After fifteen or twenty years of expansion and contraction, the adapter can deform, creating a gap that leaks combustion gases into the wall cavity. We pull the adapter, camera the flue corners for spalling, and either install a properly sized new adapter or recommend a full liner replacement if the flue is too compromised.
- Famco poured refractory liner systems (early 2000s installations): cracking and delamination from Allentown’s clay-heavy soil settlement. The Lehigh Valley’s expansive clay soil shifts foundations seasonally, and that movement transmits to chimney structures. Famco’s poured systems, while well-insulating, don’t flex. We see hairline cracks that widen to full delamination, especially on exterior chimneys on homes built before 1950. Our repair is to remove the failed refractory, assess whether the clay flue tiles beneath are salvageable, and install a new stainless liner or, if the structure requires it, rebuild the chimney from the roofline up with proper expansion joints.
Our Famco Chimney Liner & Rebuild Process
- 1
Call and schedule. A live person answers, day or night. We ask about your Famco product age if you know it, symptoms you’ve noticed, and whether you’ve burned this season. We book a Level-2 camera inspection.
- 2
Inspection and documentation. Our technician runs a camera the full liner length, photographs every joint, tee, cap, and any damage. You see the images on a tablet before we leave. We deliver a plain-English verdict: repair, replace, or rebuild, with no pressure to decide on the spot.
- 3
Parts decision. If Famco OEM parts are available and make sense for your system, we quote them. If lead times are long or an aftermarket DuraFlex, HeatShield, or Gelco component offers better longevity for your application, we explain the trade-off and let you choose. We never substitute without your approval in writing.
- 4
The repair. Background-checked, uniformed technicians arrive with the agreed parts. Most liner replacements and partial rebuilds finish in one day. For full rebuilds, we stage materials and work consecutive days until the crown is poured and the cap is on.
- 5
Testing and cleanup. We pressure-test or smoke-test every liner installation, verify draft with a manometer, and leave the work area cleaner than we found it. Photos of the completed job go to your email.
- 6
Guarantee in writing. The 90-Day Done Right Promise covers every Famco liner and rebuild job we do. If something’s not right, we make it right. No paperwork to dig up, no arguing.

Why Allentown Homeowners Call Hearthstone Chimney Co. for Famco Work
We’ve worked chimneys across Allentown for over 42 years, including older homes near the West Park neighborhood where Russell Haines and our crew have traced more Famco liner problems than we can count. The chimney doesn’t care what it looks like from the street. We check what’s inside. Our Level-2 inspections end with photos you can see and a plain-English verdict, documented like an engineer, explained like a craftsman. If your Famco system needs a part we don’t stock, our relationships with DuraFlex, HeatShield, and Gelco suppliers mean we’re not waiting weeks while burning season slips by. The 90-Day Done Right Promise is in writing, no arguing. Done right, and we stand behind it.
FAQs
Most Famco liner warranties expired after 10-15 years from installation, so for systems we see in Allentown, warranty coverage has typically lapsed. If your liner is newer, using an independent service provider like us does not automatically void a valid warranty, though manufacturer warranty service must be performed by their authorized network. We document every repair with photos and parts receipts so you have a record either way. Call (610) 632-1394 and we’ll check your install date.
Famco OEM parts often ship within 5-7 business days from regional distributors, but some tee sizes and custom diameters can stretch to two weeks or more. We stock common DuraFlex, HeatShield, and Gelco equivalents that fit Famco systems and meet the same UL 1777 standard, so most jobs don’t wait on shipping. If you prefer Famco OEM, we’ll quote the lead time upfront and you decide.
A Famco liner can be repaired if the damage is isolated: a single bad joint, a rusted cap, a separated tee collar. We repair those. If the liner shows multiple failure points, thinning walls below 24-gauge equivalent, or heat damage to surrounding masonry, replacement is the honest recommendation. We show you the camera evidence and explain which category you’re in.
Every year, before the first fire, per NFPA 211. For Famco systems in Allentown’s climate, we also recommend a mid-season check if you burn daily from November through March. Creosote accumulates faster in the corrugated flexible lines, and catching it early prevents the costly damage that leads to replacement.
Skipped maintenance on a Famco liner leads to creosote-fueled chimney fires, carbon monoxide leakage through cracked or separated joints, and accelerated deterioration of the masonry surrounding the flue. In Allentown’s older housing stock, that can mean wall cavity damage and repair bills far exceeding the cost of annual service. A Level-2 inspection runs $200-$300; a fire or CO incident costs infinitely more. Call (610) 632-1394 to schedule before you light the first fire.
