Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

We’ve worked on Gelco units in West Hartford colonials from Elmwood to the Center, and we’ve learned what fails, what parts are actually available, and when to stop repairing and start talking replacement.

How Gelco Products Fail - and How We Fix Them
- Gelco gas fireplace inserts (GL-600 and GL-800 series): The pilot assembly on these mid-2000s units collects condensation that West Hartford’s freeze-thaw cycles accelerate. We’ve replaced dozens where the pilot orifice has corroded shut. We source OEM pilot assemblies when available, or fit a compatible SIT valve kit with a brass orifice that holds up better than the original aluminum. The fix includes testing gas pressure at the manifold, not just lighting the pilot and leaving.
- Gelco wood burning fireplaces (Pre-fab Builder Series): The refractory panels in these units crack diagonally from the corner of the firebox opening, usually after five to seven seasons of heavy use. The crack itself isn’t the failure; it’s the panel shifting and exposing the metal wrapper behind it. We install replacement refractory panels cut to spec, or when Gelco panels are backordered, we use HeatShield cerfractory foam that’s rated to the same 2100°F and carries a 20-year warranty.
- Gelco chimney-top dampers (CTD series): The stainless cable on CTD-8 and CTD-10 models seizes inside the chimney flue, typically where it passes through a smoke shelf that’s never been cleaned. The homeowner thinks the damper handle is broken; it’s usually corrosion binding the cable. We drop a new cable, lubricate with high-temp graphite, and inspect the flue while we’re at it. If the damper frame itself is rusted through, we replace with a Gelco-compatible unit or upgrade to an Olympia Chimney top-sealing damper.
- Gelco direct-vent gas fireplaces (DV-32 and DV-42): The glass gasket compresses and hardens after eight to ten years, causing combustion odor complaints that homeowners mistake for a gas leak. The real issue is room air mixing with combustion air. We replace the gasket with OEM-spec braided fiberglass, check the glass for stress cracks that Gelco’s tempered glass is prone to, and verify the vent termination clearance hasn’t been compromised by a homeowner’s landscaping project.
- Gelco firebox throat dampers (cast iron, pre-1995): These warp from decades of thermal cycling and no longer seat flat. A West Hartford homeowner on Farmington Avenue had one that leaked so badly their heating bill jumped $40 a month. We measure the throat opening and either machine the original flat again (rarely worth it) or install a lock-top damper from Gelco or Copperfield that seals at the chimney top and eliminates the throat damper entirely.
Our Gelco Fireplace Services Process
- 1
Call and schedule: A live person answers, asks what you’re seeing or smelling, and books a window. We don’t use apps or callback queues.
- 2
Arrival and diagnostics: Our technician arrives uniformed and background-checked, identifies your Gelco model from the rating plate, and begins inspection. For gas units, we check manifold pressure, thermocouple output in millivolts, and venting integrity. For wood units, we camera the flue and photograph the firebox.
- 3
Plain-English verdict: You see the photos. We explain what’s wrong, what caused it, and whether it’s a safety issue or a performance issue. No recommendation without evidence you can see for yourself.
- 4
Parts decision: If Gelco OEM is available and cost-effective, we use it. If it’s backordered or discontinued, we specify a professional-grade aftermarket part from our trusted brands, DuraFlex, HeatShield, or Copperfield, and explain the trade-off. We don’t install builder-grade substitutes.
- 5
Repair and test: We complete the work, run the unit through its full cycle, and verify proper operation. Gas units get a combustion analysis when applicable. Wood units get a draft test.
- 6
Documentation and guarantee: You receive photos, a written summary, and our 90-Day Done Right Promise. If it’s not right, we make it right. In writing, no arguing.

Why West Hartford Homeowners Call Hearthstone Chimney Co. for Gelco Work
We’ve been in West Hartford long enough to know which houses on Concord Street have the same Gelco insert their builder installed in 1987. Russell Haines and our technicians have learned that Gelco units reward patience and punish guesswork. We document every inspection with photos and a plain-English verdict, back every job with the 90-Day Done Right Promise in writing, and keep professional-grade materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield on our trucks so most jobs finish in one visit. When a part is discontinued, we know the compatible replacement that won’t void what warranty remains. We’re not the cheapest option, and we don’t try to be. We’re the option that doesn’t require a callback.
Do it right the first time, or plan on doing it twice.
FAQs
Does using an independent service provider void my Gelco warranty?
No. Gelco’s product warranty covers manufacturing defects and is not contingent on using a factory-authorized servicer for routine maintenance or repair. We use OEM or equivalent professional-grade parts, and we document our work so any legitimate warranty claim remains valid. If your unit is still under warranty, we’ll note that in our report. Call (860) 743-1516 if you’d like us to review your warranty status before we start.
How do I know whether to repair my Gelco fireplace or replace it?
We recommend replacement when repair costs exceed 50% of a new unit’s installed price, when critical parts are permanently discontinued, or when the firebox wrapper has been compromised. We’ll show you the photos and run the numbers honestly. Sometimes a $400 repair buys another decade; sometimes it’s good money after bad. Call (860) 743-1516 for a free assessment.
Are Gelco parts still available, or will you try to sell me a new unit?
Many Gelco parts remain available through distribution channels, though some older series require compatible aftermarket components from HeatShield, Copperfield, or Olympia Chimney. We stock common items and have sources for obsolete parts. We only recommend replacement when repair is genuinely impractical. Call (860) 743-1516 and we’ll check parts availability for your specific model before we schedule.
How often should a Gelco wood burning fireplace be serviced in West Hartford?
Once per year, ideally before the first fire of the season. West Hartford’s oak and hickory produce more creosote than the softwoods common in other regions, and our wet springs accelerate rust on damper hardware. Annual sweeping and inspection catches what you can’t see from the hearth. Call (860) 743-1516 to book before burning season fills our schedule.
What happens if I skip service on my Gelco gas fireplace?
Deferred maintenance leads to incomplete combustion, which produces carbon monoxide and soots the glass and logs. The blower motor on GL-series inserts also fails prematurely when dust accumulates. These are gradual problems that become expensive ones. A seasonal tune-up at $189 is cheaper than a $600 burner replacement. Call (860) 743-1516 to schedule.
