If your gas logs are burning lazy yellow flames, sooting the glass, or you smell something off when the fireplace runs, that’s a drafting or burner problem, not a quirk. We’re in Windcrest weekly, and our techs know the specific failure pattern behind these 1960s ranch fireplaces that were converted from wood to gas decades ago. Call (254) 276-4116 and a live person answers, not a voicemail loop. You’ll get a written price before any work starts, every single time.
Here’s what happens when you book: the tech arrives in a tracked window, opens the firebox, checks the flue liner with a camera, and shows you photos of exactly what he found. No vague “you need a new liner” without proof. No surprise charges when someone’s already in your living room.
Why Hadley Chimney San Antonio Is Windcrest’s Preferred Gas Fireplace Repair Company
Windcrest is a small, leafy suburb of San Antonio where many homes from the 1960s through 1980s feature brick veneer and masonry fireplaces. Those fireplaces were built for wood, not gas. When someone retrofits gas logs into a 1968 firebox, the flue liner rarely gets resized, and that’s where most of our gas fireplace repair work in Windcrest starts. We carry liner inspection cameras on every truck, so when we tell you the liner is undersized or cracked, you see the footage yourself before you spend a dollar.
Cory Mitchell, who leads our crews, established Hadley Chimney San Antonio in 2003. That’s over two decades of chimney and fireplace work behind every diagnostic call. Our technicians are background-checked, uniformed, and show up in a tracked arrival window, not a four-hour guess. The Relay Visibility Guarantee applies to every gas fireplace job in Windcrest: you get live arrival tracking, before-and-after photo documentation, and a written price before work begins. Not just on big liner replacements. On every repair, including the small ones.
Every gas fireplace repair we complete carries a written guarantee and a free second visit if the repair fails. That’s the 365-Day Done Right Promise. It’s not a verbal assurance. It’s on paper, and we’ve been backing it since before most Windcrest homeowners were born.

Our Gas Fireplace Repair Services in Windcrest
Flue Liner Inspection and Resizing
Windcrest’s original 1960s ranch homes were built before modern NFPA 211 clearance standards, which means many masonry fireplaces have undersized flue liners that draft marginally even in perfect condition. A gas log retrofit in one of these fireboxes often requires a liner inspection for heat and CO clearance before a repair is safe to call done. We inspect with a camera, show you the footage, and if the liner needs work, we typically size a DuraFlex flexible liner down the existing chimney. That restores proper draft and keeps combustion gases moving up and out instead of seeping into the room.
Chimney Cap Installation
Missing chimney caps are one of the most common findings on older Windcrest homes, especially on the 1960s masonry flues around neighborhoods like East Crest and the streets branching off Midcrown Drive. Without a cap, birds and squirrels build nests in the flue during the long stretch of mild weather when fireplaces sit idle. Then the first cold snap pushes exhaust back into the living room. We install caps sized for gas fireplace venting, so draft stays consistent and the local wildlife stays out.
Gas Log Set Draft Correction
When a gas log set drafts poorly, the flame goes lazy and yellow, glass soots up fast, and you might catch the smell of combustion in the room. In Windcrest, we often trace this to leftover third-degree creosote glaze from the home’s former wood-burning era. That tar breaks loose during a gas conversion and drops chunks onto the burner, blocking the ports and choking the flame. We clean it out, correct the damper position with a proper stop so you can’t accidentally close it all the way, and dial in the air shutter. The flames should burn clean blue with yellow tips.
Gas Burner Pan and Log Control Repair
Spalling brick and missing flashing around the chimney base let humid Gulf air work its way down into the firebox. Over years, that rusts the gas burner pan and corrodes the log controls on Windcrest fireplaces that only run a few nights each winter. We test the millivolt system, check the thermocouple and thermopile, and replace rusted burner pans before they crack and leak gas. Famco and Copperfield parts are what we carry and recommend, because they’re built to handle moisture exposure without failing in two seasons.
This is where a proper gas fireplace repair inspection saves people real money. A rusted burner pan found in October is a $200 part swap. A rusted burner pan that cracks in January can mean a gas leak and a full firebox rebuild.

Common Gas Fireplace Repair Problems We See in Windcrest Homes
- Backdrafting from bird or squirrel nests: Homeowners near the Windcrest Golf Course area and along Crestway Drive regularly find uncapped chimneys have become nesting sites during the long off-season. When the gas fireplace fires up, the blocked flue pushes exhaust into the living room instead of up the chimney. The fix is cap installation plus a full flue cleaning.
- Undersized flue liners causing lazy, sooty flames: Many of these ranch homes have flue liners sized for wood smoke volume, not gas exhaust. Even a perfectly maintained gas log set will soot glass and smell off if the liner can’t carry the fumes. A camera inspection tells you in ten minutes whether the liner is the problem.
- Rusted burner pans from humid Gulf air intrusion: Missing flashing or spalled brick around the chimney base lets moisture travel down through the masonry and onto the gas burner. By the time most homeowners notice a thin flame or delayed ignition, the pan is already heavily rusted. Annual inspections catch this before it becomes a gas leak.
- Leftover creosote from the wood-burning era dropping onto gas burners: Windcrest homes that converted from wood to gas decades ago sometimes still have creosote glaze coating the smoke chamber. As the home settles and heats, chunks break free and land on the burner. This causes lazy flames, soot, and a permanent campfire smell. Sweeping the flue and smoke chamber before installing gas logs is the fix.

FAQs – Gas Fireplace Repair in Windcrest
Yes, that campfire smell in a gas fireplace almost always traces back to creosote glaze left from the home’s wood-burning era. Windcrest ranch homes built before 1980 often converted to gas logs without having the flue and smoke chamber properly swept. The heat from the gas log set reactivates that old creosote. The fix is a full flue and smoke chamber cleaning, plus a camera inspection to confirm the liner is clean and sized correctly. Call (254) 276-4116 and we’ll have an exact quote ready.
Yes, and in Windcrest specifically, the mild winters are actually part of the problem. Fireplaces sit unused for ten months, which gives birds, squirrels, and humid Gulf air plenty of time to do damage. We find nesting, rusted burner pans, and deteriorating mortar joints on gas fireplaces that run maybe six nights a year. An annual inspection with a camera costs less than a single burner pan replacement gone wrong. It’s cheap insurance against a backdraft situation in January.
The rusted burner pan gets replaced, but first we fix what caused it. In Windcrest, that usually means sealing missing flashing or repairing spalled brick around the chimney base so humid air stops leaking down into the firebox. Then we install a new burner pan, test the thermocouple and thermopile, and verify gas pressure. If the damper or liner is also compromised, we address that in the same visit. You see photos of everything before and after.
It can be, and we check it every time. Shallow fireboxes from the 1960s and 1970s were built for wood fires and often have smoke chambers that were never parged or smoothed. That rough surface catches soot and can crack over time. On a gas fireplace, those cracks become paths for carbon monoxide to migrate into wall cavities. We camera the smoke chamber, and if it needs it, we apply HeatShield ceramic compound to seal it. The alternative is larger masonry work we’ll only recommend if the photos show it’s warranted.
Yes, and we’d recommend doing it before your first burn. A gas fireplace needs a cap designed to maintain proper draft while keeping rain, birds, and squirrels out. On Windcrest’s 1960s masonry flues, the cap also helps prevent the freeze-thaw spalling that’s common on the chimney crown. We install caps sized to your flue diameter and the venting requirements of your gas log set. The cap typically runs $180 – $350, installed. Call (254) 276-4116 and we’ll quote your exact setup.
What Windcrest Homeowners Actually Deal With
Last winter our crew pulled up to a ranch on Eagle Crest Drive where the homeowner complained of a gas smell and soot on the mantel. We found the 1982 firebox was sharing its flue with a corroded draft-damaged flue liner that had never been sized for a vented gas insert, so we dropped a DuraFlex liner down the existing chimney, rebuilt the smoke chamber, and added a proper damper stop so the gas log set drafts like the original wood-burning days, minus the creosote callbacks.
That’s the job. Not a guess, not a vague warning about “dangerous conditions.” A camera, a written price, and then the fix. If your Windcrest gas fireplace is sooting, smelling, lazy-flaming, or tripping the carbon monoxide detector, the first step is simple: call us.
