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 Brentwood: What to Know First
We service Gelco gas and wood-burning fireplaces across Brentwood as an independent Gelco service provider - not a factory rep, not a franchise. Most Gelco fireplace service calls in Brentwood take 45 to 90 minutes on site, and you’ll know the price before we touch a single tool. We’re not authorized by Gelco, and that’s fine, because the work speaks for itself: we fix the fireplace in front of you, not the one the parts catalog assumes you have.
This page is for the homeowner who owns a Gelco fireplace in Brentwood, NY, and wants a straight answer about why it’s acting up, what it’ll cost, and whether it’s safe to run. If that’s you, call Wendell and the crew at Top Hat Chimney at (934) 935-3847. A live person answers, and it may well be Wendell himself.

How Gelco Products Fail - and How We Fix Them
- Gelco Vent-Free Gas Logs: Pilot light drops out when the fan kicks on. We see this on Gelco vent-free sets in Brentwood homes where the fireplace sits against an exterior wall and the vent-free burner pulls combustion air from a room that’s already cold in January. The pilot’s not weak because the thermocouple is failing - it’s drowning in a cold downdraft coming off the flue stub or the wall cavity. Fix is usually a draft shield at the flue damper pocket and a proper pilot hood adjustment, not a new thermocouple. If we can save you the $80 part, we’ll tell you.
- Gelco Direct-Vent Fireplaces: Ghosting on the glass, but not the inside of the glass. The inside is clean because the firebox is sealed. The outside face of the glass gets a white or gray haze that won’t come off with glass cleaner. That’s the appliance’s air wash system pulling in airborne minerals from a household humidifier or a gas-fired dryer venting nearby. We service dozens of these in Brentwood, especially in the older capes over near the state park where dryers vent through the same wall as the fireplace. Fix is a mineral-scrub cloth, then repositioning the external vent pickup if that’s where the minerals come from.
- Gelco B-Vent Fireplaces: Logs look fine, but the damper will not stay open. Gelco B-vent fireplaces (the ones with a standing clay or refractory liner under a log set) chew through damper pivot pins faster than any brand I’ve worked on. The pin rusts, the damper plate drops, and the fire gets lazy because it’s gulping for air. We replace the pivot pin with a stainless aftermarket pin that fits the Gelco damper bracket better than the zinc OEM part. It’s a $35 fix on a call that often starts with someone telling you you need a new firebox. You don’t.
- Gelco Inserts (2010 and later): The blower motor rattles on low speed. Gelco inserts with the factory blower shipped with a motor mount bushing that hardens over time and starts sounding like a playing card in a bicycle spoke. Most of the time the motor itself is fine. We pull the blower, replace the bushing, and test it at all three speeds. If the motor truly is going, we quote a quality aftermarket replacement in the same CFM class. Nobody in Brentwood should pay OEM markup for a generic shaded-pole fan motor.
- Gelco Wood Stoves (pre-2005): Door gasket failure on the right side only. If the rope gasket on the door is flat and shiny on the right side but still springy on the left, the door hinges have drifted. You can replace the gasket every year with OEM rope and the hinge will keep crushing it. We re-align the hinge ears with a flat bar and shim kit, fit a new gasket, then check the door latch honestly. Ten minutes of hinge work saves the next homeowner from chasing an air leak that won’t quit.
Our Gelco Fireplace Services Process
This is how a Gelco job goes at Top Hat Chimney, from the first call to the last swipe of the brush:
- 1
You call. A live person answers. No voicemail maze, no “press 2 for service.” You describe what the fireplace is doing, or not doing.
- 2
We book a window that works for you. Wendell or one of his crew shows up on time, in uniform, background-checked. If the window slips, we call you before it slips.
- 3
We diagnose in front of you. On a gas unit we test line pressure, thermocouple millivolts, pilot flame pattern, and gas valve function. On a wood-burner we check the flue, damper, gaskets, and firebox brick. Every Gelco has a nameplate with model and serial - we read it before we quote anything.
- 4
We lay out your options in plain English. OEM part, aftermarket part, or repair that costs less than either. If the unit is in good shape, we tell you. No invented emergencies.
- 5
We do the work, then test it under fire. Gas units get cycled three times cold-to-hot. Wood units get a small seasoned fire if conditions allow and the flue is prepared. We check for proper draw, clean off any debris, and leave the hearth cleaner than we found it.
- 6
You get the 90-Day Done Right Promise in writing. If it’s not right, one call brings Wendell back. No charge, no argument.
What Gelco Fireplace Services Costs in Brentwood
Here’s what you can expect to pay for common Gelco work in Brentwood. These are honest ranges, not phone quotes that change at the door. If your fireplace needs something not listed here, we give you a number before we start, and the number on the phone is the number on the invoice.
- Safety inspection of a Gelco fireplace (with combustion test): $119-$149 - no trip charge inside the county
- Thermocouple or thermopile replacement (Gelco gas units): $165-$230 - includes part and bench testing of the gas valve
- Pilot assembly rebuild including hood and orifice cleaning: $190-$260 - saves a full pilot assembly replacement when the burner tube is still sound
- Blower motor repair (bushing replacement): $95-$130 - motor replacement, if truly needed: $220-$320 with aftermarket part
- Damper pivot pin replacement: $125-$165 - stainless pin and full damper bench adjustment included
- Wood stove door gasket and hinge re-alignment: $140-$220 - rope gasket and shim work included
- Full gas fireplace service and log set re-installation: $225-$325 - not a replating; a hand-cleaning, log position correction, and burner tube health check
What moves the price: how accessible the unit is, whether we need to pull the firebox facade (some Gelco surrounds hide their mounting lags behind trim), and whether the unit is in a finished wall that requires debris containment. Repairs don’t get a surprise upcharge for a “cleanup fee” or a “hazard assessment.” And seniors and veterans get 10% off, always. Call (934) 935-3847 and tell us what your Gelco is doing - we’ll tell you what it’ll cost.
Why Brentwood Homeowners Call Top Hat Chimney for Gelco Work
Wendell Pike has been running Top Hat Chimney since 1999. That’s over 29 years of hauling brushes up onto Brentwood rooftops - plenty of capes and colonials near Brentwood State Park, and more vent-free logs than you’d think on a quiet street. He’s the guy people call when they want to know if their flue actually needs cleaning or if someone just told them it did.
On a Gelco job, you get a sweep who already knows the brand’s quirks: which vent-free sets starve for air on a cold exterior wall, which insert blowers rattle because of a $12 bushing, which damper pins snap for the fun of it. You also get the backup of the brands we trust: DuraFlex liners when a flue needs a reline, and HeatShield joint repair when a firebox needs a patch, not a rebuild. Nobody at Top Hat will sell you a liner you don’t need just because the brand name is on the truck.
Every job, every time, is backed by the 90-Day Done Right Promise. That means if the fireplace acts up again in ninety days, Wendell comes back and fixes it at no charge. Ask anyone on your street. If it needs doing, we’ll do it right. If it doesn’t, Wendell will tell you that too.
FAQs
Most Gelco warranties only require that work be performed by a qualified professional - they don’t require a factory-authorized shop. That said, using a non-factory part can void a warranty for damage related to that specific part. On a Brentwood service call we tell you plainly what’s still under warranty and what isn’t, and we never install an aftermarket part where an OEM one is still needed for fit or warranty safety.
We schedule most Gelco fireplace service calls in Brentwood within two to four business days, depending on the season and your availability. Repairs that involve a specialty part may take longer. Call (934) 935-3847 for a straight answer on scheduling. We’ll give you a real arrival window, not a four-hour “sometime between noon and your grandchild’s graduation.”
If the firebox is mechanically sound, the gas valve is in good shape, and the flue is properly lined, the right repair usually costs far less than a full replacement - sometimes half or less. We’ve kept plenty of Brentwood Gelcos running that other outfits wanted to replace. If the heat exchanger or firebox pan is rusted through, then yes, replacement is the honest answer, and we’ll show you the camera footage that proves it.
We don’t keep a warehouse full of OEM Gelco parts, because most of the common failures - thermocouples, bushings, gaskets, damper pins - are service parts we can source in a day or two. For larger assemblies like a complete pilot or a gas valve, we quote genuine parts when they matter, and quality aftermarket when they save you money without risk. We’ll never keep a fireplace down because we wanted to mark up a motor.
First-degree creosote is a brush job. Third-degree is a glaze - catch it early. On a gas Gelco, skipping combustion checks year after year lets the oxygen-to-gas ratio drift, which can soot the logs, overheat the valve, and in the worst case put carbon monoxide into the room. On a wood-burner, skipping gaskets and damper checks can turn a small leak into a chimney fire. Once a year, burn or no burn. Chimneys break in the off-season too. Call (934) 935-3847 and we’ll get it on the calendar.
