Gelco Fireplace Repair in Dallas: What to Know First
Gelco fireplace repair in Dallas typically runs between $185 and $475 for most common fixes, with pilot light repairs on the lower end and full gas valve replacements at the top. We’re an independent Gelco service provider, which means we repair these units using warranty-safe practices and quality parts without being tied to the manufacturer’s pricing or scheduling. Most Gelco repairs take one visit and about an hour to an hour and a half on site.
This page is for Dallas homeowners who own a Gelco gas fireplace, wood-burning unit, or insert and need straight answers about what’s wrong, what it costs, and whether the fix is worth it. If you’ve got a Gelco pilot light that won’t stay lit or a gas valve that clicks but never catches, call us at (361) 314-3193 and we’ll walk you through what you’re seeing before we ever schedule the truck.
How Gelco Products Fail – and How We Fix Them
Gelco has been in the gas appliance game for a long time, and the units we see in Dallas homes tend to fail in predictable ways. Here’s what we actually find when we open one up.
- Gelco gas log sets with pilot assemblies that won’t stay lit. The thermocouple on older Gelco log sets sits right in the flame path, and after enough heating and cooling cycles it develops a hairline crack in the junction. The pilot lights fine, you hold the knob for 30 seconds, and it dies the second you let go. We replace the thermocouple with a quality aftermarket part that matches the original spec and test it through five full cycles before we call it done.
- Gelco direct-vent inserts with rusted burner tubes. Dallas humidity works against gas burners, especially in homes where the fireplace sits on an exterior wall. We see burner tubes on older Gelco direct-vent units that have rusted through along the bottom seam, which causes lazy yellow flames and sooting on the glass. We pull the burner, wire-brush the intact sections, and replace the rusted tube. When the burner’s too far gone we’ll say so and quote a replacement before touching anything.
- Gelco gas valves that click but never light. The valve itself rarely fails on these units. What fails is the piezo igniter wire, which gets brittle from heat exposure and cracks the insulation. The spark never reaches the pilot hood. It’s a $12 wire and thirty minutes of labor, but it presents like a dead valve. We diagnose it with a spark tester before we ever quote a valve replacement.
- Gelco masonry fireplace doors with warped frames. We see this mostly in older Lakewood and Casa Linda homes where years of wood fires have heat-cycled the door frame. The glass still looks fine, but the door won’t close flush and smoke bleeds into the room. Sometimes we realign and shim the frame; other times the warping’s too far along and we replace the frame and reuse the glass. We’ll tell you which one you need and what each costs.
- Gelco prefab fireboxes with deteriorated refractory panels. The panels inside Gelco prefab units are made of a fiber refractory material that breaks down over time, especially if the unit was run hot. Once the panel behind the logs crumbles, the firebox can’t reflect heat properly and worsens with every use. We replace panels with material rated for the unit and inspect the firebox corners for hidden cracks while we’re in there.
Not every failing part on a Gelco needs to be OEM. Gelco doesn’t manufacture most of the components in their units anymore, and the original suppliers are the same companies making the aftermarket parts we install. We use OEM when it matters, quality aftermarket when it’s functionally identical, and we tell you which is which before you pay for anything.
Styles & brands we work with





Our Gelco Fireplace Repair Process
Every Gelco job follows the same sequence, whether it’s a pilot light repair in a gas log set or a full firebox rebuild. We tell you the price before we start, and the number on the invoice matches the number we quoted at the door.
- 1
You call, a person answers. Our phones are staffed by a live person 24/7. You describe what the Gelco unit is doing, we give you an honest read on whether it’s safe to keep using it, and we book a window that actually happens.
- 2
We show up and diagnose. The tech arrives in the window, introduces himself, and goes over the unit with you before touching anything. We use a spark tester, gas sniffer, and camera inspection to find the real problem, not just the obvious one.
- 3
We write the price down. You get a written quote for the repair, including the cost of parts, labor, and any cleanup. We explain which parts are OEM, which are quality aftermarket, and why we made that call. You approve it before we pick up a tool.
- 4
We do the work. The repair happens on the spot in most cases. We lay down drop cloths, keep the work area clean, and respect your home. The tech knows Gelco units well enough to spot related issues, and he’ll flag them without turning it into a sales pitch.
- 5
We test and document. Every Gelco repair gets a full operational test: pilot light cycles, gas valve response, burner flame pattern, and glass door seal if applicable. We take photos and note everything on the work order.
- 6
We put the guarantee in writing. Before we leave, you get a written guarantee covering the repair. If it fails inside the guarantee period, we come back and fix it at no charge. That’s the 365-Day Done Right Promise, and it’s not a handshake. It’s on paper.
That’s the Kingswell Way: say the price, show up in the window, leave it cleaner, put the guarantee in writing, come back if it fails. Nathan Corliss, our owner, sums it up like this: “Tell you the price first, do the work right, put it in writing – that’s the whole job.”

AfterWhat Gelco Fireplace Repair Costs in Dallas
Here are the numbers we actually quote in the Dallas market, not rounded-off estimates from a national call center.
| Repair | Typical Range in Dallas |
|---|---|
| Pilot light repair (thermocouple, igniter wire, pilot hood cleaning) | $185 – $285 |
| Burner tube replacement or cleaning | $275 – $425 |
| Gas valve replacement | $375 – $575 |
| Damper repair or replacement | $225 – $450 |
| Firebox panel replacement (per panel) | $150 – $350 |
| Full gas log set replacement (parts and labor) | $450 – $850 |
What moves the price is parts availability and access. A clogged pilot hood that cleans out in 20 minutes stays on the low end. A rusted burner assembly in a Gelco insert that requires pulling the whole media grate out drives it up. Older Gelco units sometimes need parts sourced from specialty suppliers, which adds a day or two and a little cost. We’ll never quote you a replacement when a repair will do, and we’ll never recommend work without showing you the camera evidence. Call (361) 314-3193 for an exact quote. Estimates are free.
Why Dallas Homeowners Call Ashby Chimney Dallas for Gelco Work
We’ve been doing chimney and fireplace work since 2002, and we’ve repaired enough Gelco units across Dallas to know their quirks without wasting your time. Our techs are background-checked and uniformed, so you know exactly who’s walking through your door. Every Gelco job gets the same treatment: a written price before anything starts, a written guarantee when we’re done, and a free second visit if the repair fails inside the guarantee period. No fine print, no restocking fees, no “that part wasn’t covered.”
Nathan Corliss grew up in Los Angeles and learned the trade at LATTC before spending years cutting his teeth on old masonry fireboxes and prefab inserts. He’s been running crews in Dallas for well over a decade, including steady work in Lakewood where chimneys often haven’t seen a brush since the Clinton years. That experience shows up when we’re standing in front of your Gelco unit: we know what’s worth fixing, what’s worth replacing, and when a repair can safely wait. When a job calls for parts outside the Gelco family, we install DuraFlex liners and HeatShield resurfacing systems, and we’ll tell you why one makes sense over the other.
Ashby carries ash right in the name. Fitting, for the people whose job is to clean it out. But ash and soot without a fix doesn’t help anyone. We write the price down, we do the repair, and we stand behind it.
FAQs
As an independent Gelco service provider, we don’t perform work that knowingly voids a manufacturer’s warranty. If your Gelco unit is still under warranty, we’ll tell you before opening it whether the specific repair could affect that coverage, and we’ll use parts and methods that keep warranty-safe practice in mind. For most units over five years old, the warranty has already lapsed and the conversation becomes about cost of repair versus replacement. Call (361) 314-3193 and we’ll help you figure out where your unit stands.
Most common Gelco parts are available, though lead times vary by component. Thermocouples, igniter wires, pilot hoods, and burner tubes are usually in stock or a day away. Less common parts, like specific gas valves or older firebox panels, may take three to five days to source from specialty suppliers. We check availability before we quote the job, so you’re never stuck waiting on a part we promised we could get.
If the firebox is sound and the gas connections are intact, repair is almost always the smarter money. A $300 pilot light repair restores a fireplace that would cost $3,000 to replace. We recommend replacement when the firebox has structural cracks, the gas valve and burner are both failing, or the unit is old enough that parts are genuinely getting scarce. We’ll show you the condition with camera photos and give you straight numbers for both paths. Call (361) 314-3193 for an honest assessment, not a sales pitch.
We’ll typically get a tech to your Dallas home within a few days, often sooner. Calls are answered by a live person 24/7, so you can book outside normal business hours if that’s when your fireplace quit on you. Once we arrive, most Gelco repairs are done in a single visit of one to two hours. If a part needs to be ordered, we’ll tell you the timeline before we leave, and you’ll know the full cost before we order it.
Yes. We repair Gelco units every week, and we also work on fireplaces and chimneys that use DuraFlex liners, HeatShield resurfacing, Olympia Chimney parts, Famco dampers, and Copperfield components. If your home has a mix of brands across the fireplace and chimney system, one call covers all of it. Call (361) 314-3193 and tell us what you’ve got.
