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 GDV-series direct-vent fireplaces - pilot assembly corrosion. The GDV-25 and GDV-36 units we see in Trenton’s 1980s and 90s split-levels develop pilot orifice blockage from humidity cycling through the Mercer County freeze-thaw season. The pilot flame weakens, then fails. We pull the assembly, clean or replace the orifice with OEM spec, and test gas pressure at the manifold - not just relight and leave.
- Gelco insert blowers - bearing wear and thermal switch failure. The CFI-42 and CFI-50 wood-burning inserts use a convection blower that runs hard through Trenton winters. After 8-12 seasons, bearings growl or the thermal switch opens early. We stock both the OEM blower assembly and a quality aftermarket equivalent; we’ll show you the price difference and let you decide.
- Gelco gas log sets - cracked refractory panels and burner pan rust. The GL-30 and GL-36 vented sets in older Trenton rowhouses near Broad Street Station sit in original fireboxes with poor draft. Refractory panels crack from thermal shock; burner pans rust where condensation pools. We replace panels with HeatShield refractory or source Gelco-spec replacements, and we check the flue before reinstalling - the real cause is often draft, not the logs.
- Gelco damper mechanisms - seized cast iron or broken throat plates. Pre-2000 Gelco wood fireplaces in Chambersburg colonials have cast-iron throat dampers that seize from creosote glazing or corrosion. We free or replace the mechanism, and if the throat plate is cracked, we fabricate a replacement or install a lock-top damper from Olympia Chimney. Either way, you get full closure and no chimney downdraft.
- Gelco direct-vent venting - failed termination cap seals and collar cracks. The co-axial venting on GDV units has a termination cap with a foam seal that degrades after 15-20 years. We’ve found collar cracks on Trenton homes where ice built up on second-story terminations. We replace with Gelco-spec or Famco-compatible termination kits, and we reseal with high-temp silicone rated for the application - not generic caulk that cures hard and splits.
Our Gelco Fireplace Services Process
- 1
Call and schedule. A live person answers, 24 hours a day. We ask the model number if you have it, the symptoms, and when you last had service.
- 2
Arrival and inspection. Our technician arrives in a marked truck, uniformed and background-checked. We inspect the unit, run a combustion test on gas models, and photograph what we find.
- 3
Plain-English verdict and upfront price. You see the photos. We explain what’s wrong, what caused it, and what it costs to fix. No surprises on the bill.
- 4
Parts decision and repair. We stock common Gelco parts and carry DuraFlex, HeatShield, Olympia Chimney, Famco, and Copperfield materials. If OEM is available and makes sense, we use it. If quality aftermarket saves you money without compromise, we show you both.
- 5
Test and document. We run the unit through its full cycle, check gas pressure or draft, and give you a written report with photos.
- 6
90-Day Done Right Promise. In writing, no arguing. If it’s not right, we come back and make it right.

Why Trenton Homeowners Call Hearthstone Chimney Co. for Gelco Work
We’ve worked on Gelco units from the rowhouses near Broad Street Station to the older colonials in Chambersburg - masonry that demands patience more than speed. Russell Haines and our crew have been at this for going on two decades, and we document every inspection with photos you can see and a plain-English verdict.
The 90-Day Done Right Promise means in writing, no arguing. Our technicians are background-checked and uniformed, and most Gelco jobs are completed in a single visit. We also work with DuraFlex, HeatShield, and other professional-grade brands, so if your Gelco unit needs a liner, cap, or repair that crosses into another system, we handle it without calling in another contractor. Done right - and we stand behind it.
FAQs
No. As an independent Gelco service provider, we use OEM-spec or equivalent parts and follow manufacturer installation procedures. Warranty coverage depends on the unit’s age and original terms, not who performs the service. We document our work with photos and parts receipts in case you ever need to file a claim. Call (856) 519-0832 if you’d like us to review your unit’s warranty status during the inspection.
Replacement becomes the honest recommendation when the firebox is cracked through, the heat exchanger is compromised, or repair costs exceed 60% of a new unit installed. For most Gelco issues - pilot problems, blower failure, damper seizure - repair is the better value. We’ll show you the camera footage and run the numbers both ways. Call (856) 519-0832 for a free estimate.
Many common parts remain available through distribution channels, though some pre-2000 components are discontinued. We stock the high-failure items - pilots, blowers, thermocouples - and we fabricate or source compatible replacements for obsolete parts when OEM is gone. We’ll tell you honestly if your unit has reached the point where parts hunting isn’t practical.
Annually, before the heating season. Even clean-burning gas units accumulate dust on burners, develop pilot orifice restriction, and experience blower bearing wear. In Trenton’s climate, the humidity swings from July to January stress ignition components more than in drier regions. Our $89 Seasonal Tune-Up covers the full safety check.
Creosote builds in the flue, the blower draws slower and overheats, and cracked refractory panels can expose surrounding structure to radiant heat. The real risk is a chimney fire or carbon monoxide intrusion - both are preventable with annual inspection and cleaning. If the chimney’s not right, the fire’s not safe. That’s the whole job. Call (856) 519-0832 to schedule.
