Homeowners in Kirby tell us the same thing: they’re tired of vague explanations and recommendations they can’t see for themselves. Our photo-first approach changes that.

Our Gas Fireplace Repair Services in Kirby
Camera Inspection Before Any Gas Repair
In Kirby, this is where every honest repair starts. Your 1950s-to-1970s chimney probably hasn’t been opened up since it was built, and you can’t make a decision about a gas fireplace without seeing what’s behind the walls. We run a camera through the flue and send you the footage. If your gas insert is venting into an unlined brick flue, you’ll see the fractured mortar and hidden gaps for yourself, and then we’ll talk about whether a repair is needed now or can wait.
Gas Log Conversion and Venting Corrections
Older Kirby homes were built around wood-burning fireplaces, and converting to gas isn’t a simple parts swap. The flue has to be sized and lined correctly for gas exhaust, and the damper needs a lockout so it can’t be closed while the gas logs are burning. We use DuraFlex liners and Olympia Chimney components when conversions require materials pros rely on, and we’ll show you the sizing math before we install anything.
Chimney Crown and Flashing Repair
Kirby’s humid, sticky summers push water into chimneys that have cracked crowns or corroded flashing. When that moisture pools in the firebox of a gas fireplace, it rusts the burner assembly and invites mold into unused flues. We repair crowns and flashing with materials built for South Texas humidity, then document the fix with after-photos you can keep.
Burner, Pilot, and Thermocouple Service
If your gas fireplace in Kirby lights and then dies, has weak flame, or won’t respond to the wall switch, the problem is usually a dirty pilot assembly, a failing thermocouple, or clogged burner ports. We’ll test each component, show you what failed, replace only what’s needed, and give you the old part back if you want it. No mystery diagnostics.

AfterCommon Gas Fireplace Repair Problems We See in Kirby Homes
- Unlined flues on gas conversions: Condensation from gas exhaust is acidic, and when it sits against old brick mortar in a 1960s Kirby chimney, it eats through the joints. The result is flue gas leaking into wall cavities where no smoke detector will catch it.
- Undersized shallow hearths: Homes built in Kirby during the 1950s and 60s often have hearths that don’t extend far enough for a gas fireplace under modern clearance codes. During extended winter use, that gap lets heat reach drywall behind the mantel and smolder it.
- Rusted burner assemblies from water intrusion: Kirby’s humid summers and the flash thunderstorms that roll through Bexar County push water through cracked crowns and failed flashing. Rusted gas burners, corroded gas valves, and mildew smell are the usual symptoms.
- Third-degree creosote glaze from prior wood burning: Even if your Kirby home now has gas logs, decades of wood fires left a hard, shiny creosote coating on the flue. That glaze is highly flammable, and any gas fireplace work on that chimney should address it first.

FAQs – Gas Fireplace Repair in Kirby
Yes, in nearly every case we see in Kirby. An unlined brick flue from the 1960s absorbs condensation from gas exhaust, and that acidic moisture pulls mortar apart from the inside. Before we convert or relight gas logs in an older Kirby chimney, we run a camera, document the liner condition, and if gaps or spalling show up, a DuraFlex liner goes in first. Call (254) 276-4116 and we’ll show you the footage before you decide anything.
That smell is usually moisture trapped in the flue or firebox from Kirby’s muggy summer air, often with mold growing in the old creosote and dust left behind. A cracked chimney crown or failed flashing lets rain pool in the bottom of the firebox, and the gas burner assembly rusts in it. We fix the water entry, clean the affected flue, and then address any burner corrosion. Call (254) 276-4116 for an inspection in Kirby.
Yes. On a 1960s single-story brick home near Old Seguin Road, our tech found a gas insert venting into an unlined masonry flue with major spalling and a rusted-out damper. The homeowner insisted it just needed a cleaning, but we showed them the camera footage of a fractured smoke chamber and third-degree creosote glaze from decades of wood burning, then lined it with a DuraFlex flue liner and replaced the damper before relighting the gas logs safely. Kirby’s expansive clay soil shifts slab foundations, and when that slab moves, the chimney often moves with it, cracking crowns and separating flashing. Call (254) 276-4116 for a documented inspection.
Third-degree creosote is a hardened, shiny glaze that sits on the flue walls like a layer of fuel. If you’re installing gas logs into a chimney with that buildup, any gas exhaust now passes through a flue that’s still dangerous, and in some cases the creosote can off-gas into the house during hot Kirby summers. We remove the glaze with professional-grade methods before converting, and we show you the before-and-after photos. Call (254) 276-4116 to schedule in Kirby.
You should require three things: footage of the flue interior showing the actual damage, photos of whatever part failed, and photo documentation after the repair. In Kirby, nothing should be recommended without visual proof you can see with your own eyes. That’s our standard on every job, and there’s no charge for the camera inspection when it’s part of a repair. Call (254) 276-4116 for a documented, honest assessment of your gas fireplace in Kirby.
