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.
HeatShield Fireplace Services in Allentown: What to Know First
We provide independent HeatShield fireplace services in Allentown, from gas fireplace tune-ups to firebox repairs and damper adjustments, with most jobs completed in a single visit and upfront pricing agreed before we start. A typical HeatShield service call runs $180-$450 depending on the system and what we find, and we book estimates at no charge.
This page is for Allentown homeowners who already have a HeatShield product installed and need it serviced, repaired, or converted. You might live in one of the older homes near West Park where HeatShield inserts were retrofitted into masonry fireplaces during the 2000s, or in a newer build with a factory-built HeatShield gas unit. Either way, the chimney doesn’t care what it looks like from the street. We check what’s inside. Call (610) 632-1394 and a live person will pick up, any hour of any day.

How HeatShield Products Fail - and How We Fix Them
- HeatShield Cerfractory Foam liner systems in Allentown’s freeze-thaw climate develop hairline shrinkage cracks where the foam meets the smoke chamber, especially after hard winters like 2022-2023. Water gets in, freezes, and opens the gap wider. We re-evaluate the bond with a Level-2 camera inspection, then reapply the cerfractory mixture only where it’s actually needed rather than respraying the whole chamber.
- HeatShield factory-built gas fireplaces (FG series) suffer from failed thermopiles after 8-12 years of steady use. The pilot stays lit but the main burner won’t kick on. We’ve found the OEM thermopile is often back-ordered 3-4 weeks; we stock a quality aftermarket equivalent that meets the same millivolt spec and gets your heat back the same day, with the homeowner’s approval.
- HeatShield wood-burning inserts with jacketed liners collect creosote in the gap between the liner and the insert body, a spot the homeowner can’t see and many sweeps miss. In Allentown, where homeowners burn oak and maple from the Lehigh Valley, this buildup accelerates. We pull the insert, clean the gap, and reseat it with proper clearance to the surround.
- HeatShield top-sealing dampers corrode at the stainless cable guide where Allentown’s acidic rain pools on the chimney crown. The damper hangs open or jams shut. We replace the cable assembly with a Gelco or Famco equivalent that uses a heavier-gauge guide, or convert to a traditional throat damper if the frame is too far gone.
- HeatShield firebox panels in prefab units delaminate from thermal cycling, especially in second homes where the fireplace goes cold for weeks then gets cranked for a weekend. The refractory surface flakes and exposes the insulating layer underneath. We source replacement panels by exact model number - HeatShield changed panel specs twice in the 2010s, and the wrong one won’t seat - and install with the factory-required air gap.
Our HeatShield Fireplace Services Process
- 1
Call and schedule. A live person answers, asks the model number if you have it, and books a window. No app, no callback queue.
- 2
Level-2 camera inspection. Our tech runs a camera through the flue and smoke chamber, photographs what we find, and explains it in plain English before any work starts.
- 3
Parts decision. If we need a HeatShield OEM part and it’s available within a week, we offer that. If it’s back-ordered or discontinued, we present a quality aftermarket alternative from DuraFlex, Gelco, or Famco with the same spec - your choice, no pressure.
- 4
The repair. Background-checked, uniformed techs complete most HeatShield jobs in one visit. We protect floors and furniture, work clean, and test every function before we pack up.
- 5
Documentation and guarantee. You get photos from the inspection, a written summary of what was done, and our 90-Day Done Right Promise - in writing, no arguing. If it’s not right, we come back.
- 6
Cleanup and close. We haul away old parts, vacuum the hearth area, and leave the work site as we found it. The number on the estimate is the number on the invoice.

Why Allentown Homeowners Call Hearthstone Chimney Co. for HeatShield Work
We’ve been working chimneys across Allentown for over 42 years, including the older brick homes near West Park where HeatShield retrofits are common. Russell Haines and our crew know the regional brick and mortar, and we know HeatShield’s product evolution well enough to spot when a part has been superseded or a spec changed.
Our 90-Day Done Right Promise means if the repair isn’t right, we make it right - in writing, no arguing. We answer the phone with a live person 24 hours a day, 7 days a week. Our techs are background-checked and uniformed, they carry DuraFlex, HeatShield, Gelco, and Famco materials on the truck, and most jobs finish in a single visit. No surprises on the bill. Done right, and we stand behind it.
FAQs
No. As an independent HeatShield service provider, we use OEM or spec-matched parts and document our work, which satisfies warranty requirements for routine service and most repairs. We are not affiliated with or authorized by HeatShield, and we never imply otherwise. If your unit is still under original factory warranty, we note that on the estimate so you can decide whether to involve the manufacturer directly. Call (610) 632-1394 and we’ll check your model year against what we know of their coverage periods.
Most HeatShield fireplace services take 90 minutes to three hours, and we complete the majority in a single visit. A gas fireplace tune-up with thermopile replacement might run two hours; a wood insert pull-and-clean with liner inspection takes closer to three. We book realistic windows and show up when we say. If we need a part we don’t stock, we’ll tell you before we start and give you the real lead time, not a hopeful guess.
Repair is usually the better value if the firebox or insert body is sound and parts remain available. We recommend replacement when the heat exchanger is cracked, the unit is discontinued with no parts support, or repair costs exceed 60% of a new equivalent. We make that call with camera evidence you can see, not a sales pitch. Sometimes the honest answer is that the repair can wait a season. We’ll say so.
Yes, if the chimney and firebox pass our Level-2 inspection. HeatShield wood-burning units often have the clearances and liner sizing needed for a gas insert or log set, but we verify with a camera before quoting. Gas conversion requires a permit in Allentown, and we handle that paperwork as part of the job. The permit fee is separate and runs about $75-$120 depending on the scope.
A stuck-open damper wastes heat and invites animals; a stuck-closed damper means you can’t safely use the fireplace. Both should be fixed before the next burn season, but neither is an emergency unless you smell gas or see smoke backing into the room. We don’t upsell urgency. Call (610) 632-1394 for a free estimate and we’ll give you a straight timeline.
