Here’s what matters for Floresville homeowners specifically: the older brick chimneys in this area carry decades of oak and mesquite creosote, even after a gas conversion. That legacy creosote blocks draft, rusts dampers faster in South Texas humidity, and hides cracks that a visual check misses. Before we fix your gas fireplace, we need to know what the flue actually looks like. That’s why camera inspection is standard on every Floresville job we do, not an upsell.

Our Gas Fireplace Repair Services in Floresville

Gas fireplaces in Floresville break in patterns. The humidity rusts controls. Old creosote from wood burning restricts draft. Converted fireboxes develop cracks in the brick and rust in the damper. We address all of it, and here’s how each service works on a typical Floresville home.

Flue Liner Inspection and Replacement

This is the service we push hardest in Floresville, and there’s a specific reason. On the east side near the old peanut mill, many original brick chimneys from the early 1900s still have unlined flues, meaning the inside of the chimney is raw brick with no protective sleeve. Over decades, heat and moisture cause hairline cracks in the mortar joints. If you run a gas fireplace through a cracked flue, combustion gases can seep into wall cavities instead of venting outside. That’s a carbon monoxide risk, not a cosmetic issue. We run a camera through every flue before doing any gas repair on an older Floresville home. If the liner is compromised, we replace it with a DuraFlex stainless liner sized to your existing chimney. The fix typically runs $1,800 to $3,200 depending on flue height and access, and you see the camera footage yourself before we quote anything.

Gas Log Set Repair and Conversion

Floresville has a lot of converted fireplaces, wood-burning boxes that a previous owner or a flipper turned into gas. The problem with conversions is the firebox wasn’t designed for gas heat, so brick spalls and cracks around the burner. We repair fireboxes with HeatShield, a ceramic compound that resists temperatures up to 2,400 degrees. We also convert wood fireplaces to gas properly, using Copperfield or Famco gas log sets sized to your firebox. A typical gas log set repair or burner servicing in Floresville lands between $180 and $320, while full conversion work ranges from $600 to $1,400 depending on the firebox condition. Call (254) 276-4116 and we’ll give you a written price before we start anything.

Damper Repair and Replacement

South Texas humidity is hard on dampers. They sit in the firebox all summer, absorbing moisture from the air, and rust forms. By the time a Floresville homeowner fires up the gas logs in November, the damper often won’t open fully or won’t seal when closed. A rusted damper on a gas fireplace is doubly dangerous: if it’s stuck open, you lose conditioned air up the flue all year; if it’s stuck closed, combustion gases have nowhere to go. Damper repair usually runs $140 to $280 on a standard Floresville chimney. Replacement with a top-sealing damper runs $350 to $600. We check the damper on every gas service call as a matter of course, because in this humidity, it’s usually rusted.

Burner and Pilot Assembly Service

If your gas fireplace in Floresville won’t light, the culprit is usually a thermocouple, a thermopile, or a dirty burner. The thermocouple is a small safety sensor that shuts off gas if the pilot goes out. In Floresville’s humid air, these corrode faster than they do in drier climates. Burner ports also clog with dust and old creosote, especially if the fireplace was used for wood before conversion. A standard burner cleaning and pilot assembly check runs $120 to $200 in Floresville. We stock common replacement parts for all major gas log brands, so most jobs are done in a single visit.

Trusted Brands We Service in Floresville

We work on gas fireplaces and gas log sets from the brands Floresville homes actually have: Copperfield, Famco, Monessen, Heatilator, and more. The parts matter. We install Copperfield gas log sets and Famco dampers specifically because they hold up better in South Texas humidity than budget alternatives we could put on the truck. For flue liners, we use DuraFlex stainless systems, and for firebox repair we use HeatShield ceramic compound, the same material used in commercial restoration work. We stock common parts locally and order specialty pieces with a quick turnaround, so your Floresville repair doesn’t stretch into weeks.

Common Gas Fireplace Repair Problems We See in Floresville Homes

Here’s what actually shows up on our Floresville work orders, week after week:

• Creosote from previous wood burning blocks the draft. Oak and mesquite burned in the same firebox leaves a tar residue in the smoke chamber. After a gas conversion, that old creosote restricts airflow, the burner shuts off, or soot backs into the room. The fix starts with camera inspection to see what’s actually up there.
• Unlined flues with hidden cracks on east-side homes. The original chimneys near the old peanut mill often run without a liner. Heat stress and moisture open cracks in the mortar. A gas repair that skips flue inspection leaves a real carbon monoxide path open. We won’t do it.
• Rusted dampers from summer humidity. Floresville’s hot, humid summers mean dampers absorb moisture for six months straight. By the first cold snap, the damper is seized or the linkage is corroded. Pre-season checks catch it in September instead of November.
• Spalling firebox brick after a wood-to-gas conversion. Gas fires produce more direct heat on the back wall than wood fires do. Converted fireboxes crack, and small chunks of brick start to flake into the burner. We repair with HeatShield and rebuild the firebox floor when needed.

On a ranch-style home off old peanut mill road, Cory arrived to find a gas fireplace with a Copperfield gas log set that had been converted from a wood-burning firebox years earlier. The firebox brick was spalling, the damper was rusted open, and the homeowner had been fighting backdraft issues for two winters. Our crew replaced the damper, rebuilt the firebox with HeatShield, and ran a camera inspection that showed first-degree creosote still coating the smoke chamber from old oak fires before the conversion. The fireplace isn’t just fixed, the flue is actually safe to run. That’s the difference on an older Floresville home, and it’s why we don’t sell gas repairs without looking at the whole chimney.
