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.

How Gelco Products Fail - and How We Fix Them
- Gelco Pre-Fab Firebox cracking in Allentown’s freeze-thaw cycle. The steel fireboxes in Gelco’s prefabricated wood-burning units expand and contract through Lehigh Valley winters more aggressively than the design anticipated. Hairline cracks at the weld seams widen, and you smell smoke in the room before you see damage. We inspect with a camera, document the crack location, and either weld-repair or source a factory-spec replacement firebox - never a generic fit.
- Gelco gas insert pilot assembly failure in Series 600 and 800 units. These pilots use a specific ceramic generator that degrades faster when the unit cycles on and off frequently, which happens in Allentown’s shoulder seasons when homeowners toggle between heating modes. The symptom is a pilot that lights but won’t hold. We carry the OEM SIT valve and pilot generator on the truck, or we can install a quality aftermarket assembly if the OEM backorder stretches past burning season.
- Gelco damper corrosion in vented gas log sets. The cast-aluminum dampers on older Gelco vented units corrode where the flue gases condense, especially in Allentown homes with marginal draft from shorter chimneys. The damper hangs open, bleeding heat all winter. We measure the throat precisely and install a Gelco-spec replacement or a stainless aftermarket damper from our Famco inventory if the original is discontinued.
- Gelco direct-vent terminal blockage from cottonwood and maple seed. Allentown’s mature tree canopy - particularly in the West End and near Cedar Creek Park - sends debris into Gelco’s low-profile horizontal terminals. The pressure switch trips, and the unit shuts down. We clear the terminal, check the combustion-air intake for nesting, and install a raised or screened termination if the location demands it.
- Gelco refractory panel delamination in wood-burning fireplaces. The refractory panels in Gelco’s Builder’s Choice and Elite series flake at the edges after repeated thermal shock. Once the steel backing shows through, the firebox is no longer UL-listed for wood burning. We source Gelco-spec 1-inch or 1.25-inch replacement panels, or we can reline with HeatShield Cerfractory foam if the damage is localized and the homeowner prefers that route.
Our Gelco Fireplace Services Process
- 1
Call and schedule. A live person answers, asks what you’re seeing, and books a window that works. No app, no callback queue.
- 2
Arrival and inspection. Our technician arrives uniformed and background-checked, lays down protective coverings, and runs a Level-2 camera inspection. You see the photos on the tablet as we find them. The chimney doesn’t care what it looks like from the street. We check what’s inside.
- 3
Diagnosis and parts decision. We identify the Gelco series, check parts availability, and present both OEM and quality aftermarket options where they exist. We explain the trade-off in durability and warranty coverage, and you choose.
- 4
Upfront pricing and repair. You get a written estimate with one number. That’s the number on the invoice. We complete most repairs in the same visit.
- 5
Testing and documentation. We fire the unit, check gas pressure or draft, and record performance. You get photos, a plain-English verdict, and our 90-Day Done Right Promise in writing.
- 6
Cleanup and follow-up. We leave the work area as we found it. If anything isn’t right, we come back. No paperwork, no arguing.

Why Allentown Homeowners Call Hearthstone Chimney Co. for Gelco Work
We’ve worked chimneys across Allentown for over 42 years, including the older brick homes near West Park where Gelco inserts were retrofitted into masonry fireplaces in the 1990s. Russell Haines and our crew know the regional brick and mortar, the local draft conditions, and the Gelco product line well enough to spot a parts mismatch before it gets ordered. We document every inspection with photos you can see and a plain-English verdict. Our 90-Day Done Right Promise is in writing with no arguing. And because we also stock DuraFlex liner and HeatShield refractory materials, we’re not stuck when a Gelco part is backordered or discontinued. A square deal, no surprises on the bill, and we’ll be there when we say.
FAQs
No. As an independent Gelco service provider, we perform warranty-safe work using OEM or equivalent parts, and we document everything. If your unit is still under manufacturer warranty, we note that in our report so you have records if you ever need them. Call (610) 632-1394 to schedule - estimates are free.
Common Gelco service parts - pilot assemblies, refractory panels, dampers - are usually in stock or available within 3-5 business days. Discontinued series may require us to source compatible aftermarket parts from our Famco or Copperfield inventory, which we can often do same-day. We’ll tell you exactly where your part stands before we book the repair.
Repair makes sense when the firebox, gas valve, and venting are sound and parts remain available. Replacement becomes the better value when the unit is pre-1990, the firebox is cracked through, or multiple major components have failed. We show you the camera evidence and give an honest recommendation either way - no upselling. Call (610) 632-1394 for an inspection.
Once yearly, before the heating season begins. Gas fireplaces burn cleaner than wood, but the burner ports still clog, the pilot still degrades, and the vent terminal still collects debris. An $89 seasonal tune-up catches problems before they become after-hours emergency calls in January.
Deferred maintenance on a wood-burning Gelco risks creosote buildup and chimney fire. On a gas Gelco, it risks incomplete combustion, carbon monoxide venting issues, and component failure that leaves you without heat on the coldest night. Neither outcome is worth gambling on. We don’t scare-sell, but we do show you what we find and explain what it means.
