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 Hagerstown: What to Know First
We service and repair Gelco fireplaces in Hagerstown, and we do it as an independent provider, not a manufacturer rep. Most Gelco jobs take a single visit, usually under two hours, and you’ll know the price before any tool comes off the truck. If your Gelco is burning weak, sooting up the glass, or throwing a gas smell you can’t place, call (240) 534-1247 and we’ll tell you what we’re likely dealing with before we even arrive.
This page is for Hagerstown homeowners who own a Gelco gas fireplace, wood-burning unit, or insert and want straight answers on service: what breaks, what it costs, and when it’s honestly fine to hold off. Wendell Pike owns Top Hat Chimney, and he has been working on fireplace systems across Washington County long enough to know that a Gelco has a few habits all its own.
Key takeaways:
- Gelco fireplaces in Hagerstown tend to fail in predictable ways: pilot assemblies, gas valves, and gasket seals on the glass front.
- We’re an independent Gelco service provider, not authorized by the manufacturer, which means we can be honest about what actually needs replacing.
- Every Gelco job comes with the 90-Day Done Right Promise in writing.

How Gelco Products Fail - and How We Fix Them
Gelco built a lot of fireplaces in the 1990s and early 2000s, and plenty of them are still running in Hagerstown homes today, especially in the older neighborhoods around Jonathan Street and over toward the county line. Here’s what we actually see when those units come due for service. Your flue doesn’t care how the fire looks. It cares how it breathes.
- Pilot assembly failures on the Gelco B-Vent and Direct Vent lines. The thermocouple and thermopile in older Gelco pilot assemblies wear out slowly, and the symptom is usually a fireplace that lights, runs a few minutes, then shuts off cold. Homeowners often assume the gas valve is dead. More often, it’s the pilot. We test both before recommending a repair, because a $40 thermopile beats a $300 valve any day.
- Glass gasket seal breakdown on Gelco Direct Vent units. The rope gasket around the glass front dries out and crumbles after a decade or so of Maryland heating seasons. When it goes, combustion air leaks into the room instead of staying in the firebox, and you get soot building up on the glass faster than it should. We replace the gasket, check the glass for hairline cracks, and retest the seal.
- Gas valve sticking on Gelco log sets and stoves. Gelco used a few different valve configurations over the years, and the older standing-pilot valves get gummed up when the fireplace sits unused all summer. The burner lights weak or not at all on the first cold night of fall. Sometimes a cleaning is all it takes. Sometimes the valve is done. We’ll show you the difference on camera before we spend your money.
- Burner pan rust-through on Gelco wood-burning prefab units with gas log conversions. This one is specific to Hagerstown’s humidity. A wood-burning Gelco firebox that later got a gas log set retrofitted often has a steel burner pan under the logs that rusts from condensation. The flame gets lopsided, and eventually you get gas pooling where it shouldn’t. We replace the pan, not the whole appliance, unless the firebox itself is compromised.
- Venting joint separation on Gelco B-Vent fireplaces in older Hagerstown homes. Homes settle, and B-vent pipe sections can pull apart inside the chase. You won’t see it from the living room. What you’ll notice is a faint exhaust smell when the fireplace runs, or soot staining on the wall above the mantel. First-degree creosote is a brush job. Third-degree is a glaze. This one is a real exhaust leak, and we fix it before it becomes anything worse.
Our Gelco Fireplace Services Process
Here’s how a Gelco job goes when you call Top Hat Chimney:
- 1
You call (240) 534-1247. A live person answers, around the clock, and it may well be Wendell himself. You describe the symptoms. We tell you honestly if it sounds urgent or if you can wait.
- 2
We arrive and look. Background-checked, uniformed crew, real arrival window. We don’t just start swapping parts. We inspect the whole fireplace: gas line, valve, pilot, burner, gaskets, glass, venting, and the chimney above if it’s a wood-burner.
- 3
Camera inspection. The camera footage and a plain-English verdict, every time, no exceptions. If we’re telling you something needs replacing, we show you why.
- 4
Parts decision. For Gelco-specific components, we use OEM parts when they’re available and when they’re the right call. When a quality aftermarket part does the same job for less, we tell you that and let you decide. No mystery parts, no padded ticket.
- 5
The repair. We do the work, test everything, run the fireplace through a full cycle, and clean up after ourselves. The house looks the way it did before we got there.
- 6
Your guarantee. Every Gelco job gets the 90-Day Done Right Promise in writing. If it’s not right, one call brings us back at no cost to you.

What moves the price is parts availability and how much of the unit has to come apart. Older Gelco models sometimes need a part sourced through a distributor, and that can add a few days. We’ll tell you upfront. And remember: $40 off any repair over $200, no trip charge inside the county, and 10% off for seniors and veterans. If you’ve got a written estimate from someone else, bring it in and we’ll give you a free second opinion.

Why Hagerstown Homeowners Call Top Hat Chimney for Gelco Work
Wendell Pike has been running a brush and turning wrenches across Washington County since 1999. That’s more than 29 years of showing up, naming a price, and standing behind the work. He put his own name on this company, and he runs into you again at the hardware store or the Saturday market. That changes how he does the job.
We work on Gelco every season, but we also work with DuraFlex and HeatShield when a fireplace or chimney needs something Gelco doesn’t make. That matters when your Gelco fireplace has venting issues and the fix involves a liner we trust from another manufacturer. We’re not tied to one brand’s catalog. We’re tied to what actually solves the problem for your house in Hagerstown.
And if it doesn’t need doing, we’ll tell you that first.
FAQs
No. You have the legal right to use an independent service provider. We’re not authorized by Gelco, and we don’t claim to be. What we do is use OEM parts where they matter and document everything, so if you ever need to file a warranty claim, you’ve got a clear record of what was done and why.
Common parts like pilot assemblies, thermopiles, and gaskets are usually in stock or available within a couple of days. Older or less common Gelco components may take a week or so from a distributor. We’ll tell you the expected timeline before we order anything.
That depends on what’s failing. A pilot or gasket issue is almost always a repair. If the firebox is cracked, the venting is separating, or the gas valve is the second one to go in five years, replacement starts to make more sense. We’ll show you the camera footage, price both options honestly, and let you decide. No pressure.
Most calls are scheduled within a few days, and we keep slots open for situations that can’t wait. Call (240) 534-1247 and a live person will let you know when Wendell can be there.
Yes, if the firebox and chimney are in good shape for it. We convert wood-burning Gelco units to gas log sets or inserts, and we’ll be straight with you about whether your particular unit is a good candidate. Some older prefab Gelco fireboxes aren’t rated for conversion, and we won’t do it just to make a sale.
