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.

AfterGelco Fireplace Services in Pottstown: What to Know First
We provide independent Gelco fireplace services in Pottstown, from gas valve troubleshooting to firebox refractory panel replacement, with most repairs completed in a single visit and upfront pricing before any work begins. Gelco units are built to last, but after fifteen to twenty years in a Montgomery County climate, the gaskets wear, the pilot assemblies soot up, and the dampers start sticking. We’re not here to sell you a new fireplace unless you actually need one.
This page is for Gelco owners in Pottstown, Stowe, and the surrounding townships who want the unit fixed right, documented with photos, and backed by a guarantee in writing. Call us at (610) 819-4281 - a live person answers, 24 hours a day.

How Gelco Products Fail - and How We Fix Them
- Gelco gas fireplace inserts (GDV series): The pilot assembly on GDV-32 and GDV-36 units collects silica dust from Pottstown’s hard water and clay-heavy soil, causing intermittent ignition or a pilot that won’t stay lit. We disassemble and clean the pilot orifice with a calibrated wire set, never a drill bit that widens the aperture, then test flame rectification with a microamp meter before we leave.
- Gelco wood-burning fireplaces (Pre-Fab models): The refractory panels in older Pre-Fab fireboxes develop hairline cracks from thermal cycling through our freeze-thaw winters. Gelco panels are no longer manufactured for some 1990s units, so we source HeatShield-compatible refractory or custom-cut panels from Copperfield that match the original thermal rating without voiding your remaining structural warranty.
- Gelco chimney-top dampers: The stainless cable on Gelco top-sealing dampers corrodes at the eyelet where it exits the flue, especially on homes near the Schuylkill where humidity hangs heavier. We replace with a DuraFlex-compatible cable assembly rated for 1,200 degrees, or convert to a lock-top damper if the flue tile is too deteriorated for the original mounting bracket.
- Gelco gas log sets ( vented and vent-free): The ember bed on vented sets compresses over time, redirecting flame impingement onto the burner pan and causing premature rust. We re-grade the ember material, check orifice alignment with a manometer, and verify gas pressure at the valve - low inlet pressure is common in Pottstown’s older neighborhoods where the service line hasn’t been upgraded.
- Gelco fireplace doors and gaskets: The woven fiberglass door gasket on older units hardens and shrinks, leaking room air into the firebox and killing draft on wood-burning models. We measure the channel, match the rope diameter to within 1/16 inch, and set it with Furnace Cement rather than silicone, which outgasses and cracks at fireplace temperatures.
Our Gelco Fireplace Services Process
- 1
Call and schedule. A live person answers, asks what you’re seeing and hearing, and books a window that works. No app, no callback queue.
- 2
Level-2 camera inspection. Our technician arrives in uniform, runs a chimney camera, and photographs every Gelco component - firebox, damper, gas valve, pilot assembly, liner condition. You see the photos on a tablet before we write the estimate.
- 3
Plain-English estimate. We explain what’s wrong, what Gelco parts are available (OEM, aftermarket, or cross-compatible from our DuraFlex and HeatShield inventory), and what each option costs. The number we quote is the number on the invoice.
- 4
The repair. Most Gelco jobs finish in one visit because our trucks carry common failure parts - pilot assemblies, gaskets, refractory panels, damper cables. If we need to order a specialty Gelco component, we tell you exactly when it will arrive.
- 5
Testing and documentation. We pressure-test gas connections with a digital manometer, verify draft with a smoke pencil, and burn the unit through a full cycle. You get printed photos, the verdict in writing, and our 90-Day Done Right Promise.
- 6
Cleanup and follow-up. We leave the hearth cleaner than we found it. If anything isn’t right, call us. We come back. In writing, no arguing.

Why Pottstown Homeowners Call Hearthstone Chimney Co. for Gelco Work
We’ve been sweeping and repairing chimneys in Pottstown since 1984. Russell Haines has run hands-on service here for the better part of two decades, including plenty of older homes over near Manatawny Street where the chimneys are as stubborn as they are historic.

Our technicians are background-checked, uniformed, and trained on Gelco’s specific quirks - not just generic gas fireplace repair.

A live person answers the phone every hour of every day. Most jobs finish in one visit. The estimate is the invoice.
FAQs
No. As an independent Gelco service provider, we use OEM or equivalent professional-grade parts and follow manufacturer installation procedures, which preserves any remaining warranty coverage. We document our work with photos in case you ever need to file a claim. Call (610) 819-4281 if you have questions about your specific warranty status.
For many discontinued Gelco series, yes - we source through our network including Copperfield and Olympia Chimney, and we cross-reference compatible components from HeatShield and DuraFlex where Gelco OEM is no longer manufactured. For some 1980s and early-1990s units, we may need to fabricate or adapt, which we’ll explain before any work begins.
Replacement only makes sense when the firebox or heat exchanger is structurally compromised and cannot be safely relined or patched - something we determine with a camera inspection, not a guess. Most Gelco issues are repairable: stuck dampers, worn gaskets, failed pilots, cracked refractory. We’ll show you the photos and tell you straight which category you’re in.
Gas Gelco fireplaces need annual inspection and cleaning of the burner, pilot, and venting. Wood-burning Gelco units should be swept after every cord of wood burned, or annually if used regularly, because Pottstown’s oak and hickory produce acidic creosote that accelerates wear on the refractory and damper. Our $89 seasonal tune-up covers the inspection and basic cleaning.
Deferred maintenance leads to bigger repairs: a dirty pilot becomes a failed ignition control, a cracked refractory panel lets heat reach the metal firebox and warps it, a stuck damper traps moisture and rots the chimney from inside. Carbon monoxide risk increases on gas units with blocked or leaking vents. The cost of prevention is always lower than the cost of the failure.
