Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Gelco Fireplace Services in Hempstead: What to Know First
Gelco fireplace service in Hempstead runs about $189 to $410 for most repairs, depending on whether we’re chasing a pilot issue or replacing a thermocouple, and we can usually get to you within a few days. We’re an independent Gelco service provider, which means we fix them, clean them, and convert them without any corporate runaround. If you own a Gelco and your fire’s acting strange, call (516) 963-1068 and you’ll get a straight answer before you spend a dime.
This page covers the stuff Gelco’s own manual won’t tell you: what fails on these units after ten years of Hempstead winters, which parts are worth paying OEM prices for, and when you’re better off replacing than repairing. No pressure. If it doesn’t need doing, we’ll tell you.

How Gelco Products Fail - and How We Fix Them
Gelco makes solid fireplaces, but every brand has its weak spots. Here’s what we see most often when we pull up to homes around Hempstead, from the older stock near Hofstra University to the newer builds south of Hempstead Turnpike.
- Thermocouple failure on Gelco direct-vent units. The thermocouple sits in the pilot flame and tells the gas valve it’s safe to stay open. After six or eight Long Island heating seasons, corrosion from salt air and indoor humidity weakens the signal. Your pilot lights fine, you hold the knob, release it, and it goes out. We see this constantly on the 3000 and 4000 series units. Fix is usually a factory thermocouple, about an hour of labor, done.
- Burner carry-over ports clogged on the 5000 series. The little slots that carry flame from the pilot to the main burner collect dust, pet hair, and the fine grit that blows in through older Hempstead windows. You get lazy orange flame on one side and nothing on the other. It’s a cleaning job, not a parts job, unless the ports have rusted through. We clean them with the right diameter wire and check gas pressure while we’re in there.
- Glass gasket leakage on Gelco sealed units. The rope gasket around the viewing glass compresses over time. Once it loses its spring, combustion air leaks in where it shouldn’t. Soot builds up on the glass from the inside, flame patterns go wobbly, and you get that faint smell of exhaust in the room. OEM Gelco gaskets are worth the extra $20 because the density matches the door channel. Aftermarket rope can be too thick and make the door hard to latch.
- Damper linkage slop on wood-burning Gelco models. The damper handle and linkage loosen up with use. You push it closed but the damper plate doesn’t fully seat. Cold air drops down the flue all winter, and in summer you lose air conditioning up the chimney. It’s usually a worn pivot pin or a stretched tension spring. Ten-minute fix if the plate itself isn’t warped.
- Log set deterioration on Gelco vented gas models. The ceramic fiber logs look fine until you touch them, and then they crumble. Gelco used a lighter-density mix on some 2000 series production years. We’ve seen logs disintegrate during routine cleaning. The fix is a factory replacement set, matched to the burner, or converting to a more durable aftermarket set that’s sized right for the hearth opening. We’ll show you both prices and let you pick.
Our Gelco Fireplace Services Process
When you call us for Gelco work in Hempstead, here’s what happens, start to finish.
- 1
You call (516) 963-1068. A live person answers. It might be Wendell Pike himself. We ask what the fireplace is doing, what model you have if you know it, and when you’re home.
- 2
Wendell or one of his crew arrives. Uniform, background-checked, and he calls if traffic makes him late. No four-hour windows.
- 3
Diagnostics, camera included. We inspect the unit, run it if it’s safe, and put a camera up the flue when the problem involves venting. You see what we see.
- 4
Plain-English verdict. Here’s what’s wrong, here’s what it costs to fix, and here’s what can wait. If it’s not worth fixing, we say so. We’d rather lose a job than sell you one you don’t need.
- 5
The repair, priced before work begins. That number you heard is the number on the invoice. No surprises at the door.
- 6
Test fire and cleanup. We run the unit through a full cycle, check vent draw, and leave the hearth cleaner than we found it. Then the 90-Day Done Right Promise applies, in writing, on every Gelco job we finish.
What Gelco Fireplace Services Cost in Hempstead
Most Gelco service calls in Hempstead land between $189 and $410. Here’s the breakdown:
- Service call and diagnosis: $89 to $149, waived when you approve the repair
- Thermocouple or thermopile replacement: $189 to $280
- Burner cleaning with gas pressure check: $160 to $240
- Glass gasket replacement: $140 to $220

- Fireplace conversion (wood to gas or vented to ventless, where code allows): $750 to $2,400, quoted after we see the firebox and existing venting
What moves the price is parts: OEM Gelco thermocouples and gaskets cost more than generic and last longer, so we stock both and tell you the difference. We offer $40 off any repair over $200, a free second opinion on any written estimate, no trip charge inside the county, and 10% off for seniors and veterans. Call (516) 963-1068 for a free estimate.
Why Hempstead Homeowners Call Top Hat Chimney for Gelco Work
Top Hat Chimney has been owned and operated by the same person since 1999. Wendell Pike puts his name on every job, and you might run into him at the hardware store on Saturday. That changes how work gets done. The 90-Day Done Right Promise is stamped on every invoice, in writing. If the repair doesn’t hold, one call brings the crew back. No arguments, no charge.
We know Gelco units because we’ve been inside hundreds of them across Hempstead, from split-levels off Peninsula Boulevard to colonials near the country club. And when a Gelco part is discontinued or backordered, we don’t leave you hanging. We work with DuraFlex and HeatShield products for liners and refractory repairs, which means we can usually source a compatible fix without waiting on a factory container that may never show. Call (516) 963-1068 and ask for a time. The phone rings, a person answers.
FAQs
No. An independent Gelco service provider working on your unit does not void the warranty, as long as we follow factory specifications and use compatible parts. We recommend OEM parts for warranty-covered components when your unit is still under coverage, because aftermarket parts can complicate a claim. We’ll tell you which is which before we order anything.
Many common parts are still available, like thermocouples, thermopiles, gas valves, and gaskets. Some older Gelco log sets and glass frames have been discontinued, and that’s where we’ll level with you: if sourcing a part takes six weeks and costs more than half the price of a replacement unit, we’ll show you the math and let you decide. We maintain supplier relationships for hard-to-find Gelco components, but we won’t pretend a discontinued part is easy when it isn’t.
Usually within a few days, and we keep more urgent slots available during heating season because a fireplace that won’t run or won’t shut off is a safety issue. Call (516) 963-1068 and we’ll give you a real arrival window, not a four-hour range.
Once a year, burn or no burn. Gas fireplaces build up dust on burners and pilots even when they sit idle, and wood-burning Gelcos accumulate creosote that gets more dangerous with each season you ignore it. Annual service catches the gasket wear and damper slop before they become real problems, and it’s cheaper than the repair you’ll need if you wait.
Yes, if the firebox size and existing venting allow it. We’ve converted plenty of Gelco wood units in Hempstead to direct-vent gas inserts or vented gas logs, depending on what the chimney inspection shows. It starts with a camera inspection and an honest assessment of what your fireplace can handle. Call (516) 963-1068 and we’ll set it up.
