Call us at (903) 515-5079 and a live person answers, any hour.

Why Alcott Chimney San Antonio Is the Repair Team Lackland AFB Families Call
Ruben Castellano built this business on a simple rule: show the customer what’s actually wrong before asking them to pay for anything. That matters more on base than anywhere else we work. A gas fireplace repair that isn’t documented with clear camera evidence can delay a housing clearance or force a rapid re-inspection. So we hand you photos and video from the inspection before we quote a single dollar.
Every technician who arrives at a Lackland AFB address has passed a background check and identity verification under the Threshold Standard. You get the tech’s name and photo before we arrive, and they show a photo ID badge at the door. No exceptions. If you’re home alone or with young kids, that matters.
Since 2002, Alcott Chimney Sweep has been part of the Threshold Group family of home-service companies, and our crews serve Lackland AFB directly. We answer every call with a real person, not a queue that tells you to press one for more options.

Our Gas Fireplace Repair Services in Lackland AFB
Flue Liner Inspection and Relining
Most fireplaces in Lackland AFB’s mid-century brick duplexes were built for wood, not gas. Many have unlined or clay-tile flues that crack under the heat cycling of intermittent gas fireplace use. Those cracks leak carbon monoxide between quarterly inspections, which is exactly the kind of deficiency the Air Force Housing Management Office is trained to spot. We run a Level 2 camera inspection, show you the live feed, and if the liner has failed we install a DuraFlex stainless liner sized to your existing flue. You get the camera video and a written report you can hand directly to housing.
Damper Replacement
A rusted or missing damper is one of the most common complaints we hear from Lackland AFB residents. Humid San Antonio air seeps through an open damper, condenses inside the firebox, and leaves a smoky, musty smell that gets worse on windy days. Housing inspectors flag it, but the fix is usually straightforward: a new Famco or Copperfield damper installed and sealed. We show you the before and after on camera.
Chimney Cap Installation
Wind-driven drafts and the occasional cold snap make a missing chimney cap more than a nuisance on base. It lets rain soak into the flue, it lets birds and debris build nests, and it makes a gas fireplace smell like a wet ashtray when the wind shifts. We install Olympia Chimney caps sized to your flue and seal the crown so moisture stops getting in. If your home has a poorly sealed flue, this is often the difference between passing and failing an inspection.
Pilot Assembly and Thermocouple Repair
Gas fireplaces that sit unused for months during San Antonio’s mild stretches often fail to light on the first cold snap. The pilot assembly gets dusty, the thermocouple loses its signal, and the unit shuts off mid-burn. We carry replacement parts on the truck for most common brands, so a thermostat or pilot repair is usually handled in one visit. We don’t leave a Lackland AFB home without firing the unit and showing you the flame pattern is correct.

Common Gas Fireplace Repair Problems We See in Lackland AFB Homes
- Cracked clay-tile flue liners: The mid-century duplexes across Lackland AFB were built with clay tile. Gas fireplace heat cycling cracks those tiles within a decade or two, and CO leaks follow. A camera inspection is the only way to see it.
- Soot buildup flagged by quarterly inspections: The Air Force Housing Management Office treats gas fireplace soot as a health and safety issue, not a cosmetic one. Fast, documented cleaning and repair is the difference between clearance and a re-inspection.
- Missing or rusted dampers: Humid air from San Antonio’s long stretches of mild weather condenses inside the firebox and turns a small damper issue into a spalling brick problem. Windy days push that smell through the house.
- Gas fireplaces vented into old wood chimneys: Many base homes have gas units tied to flues that were never sized or lined for gas exhaust. The gas burns cleaner but hotter at the vent, and the old clay can’t handle it. Relining fixes the problem permanently.

FAQs – Gas Fireplace Repair in Lackland AFB
Yes, when the repair is done to code and documented with a camera inspection report. The Housing Management Office wants to see that the flue is clear, the liner is intact, and the unit drafts properly. Our Level 2 camera inspection produces dated photos and video you can submit directly to housing, and we write the report in the format they expect. Call (903) 515-5079 to schedule before your next inspection window.
Almost always, it’s a missing or poorly sealed damper combined with a flue that lets wind push air back down into the firebox. Humid San Antonio air condenses on the soot inside the chimney, and the downdraft carries that smell into your living room. Installing a proper damper and a wind-resistant cap usually ends the problem in one visit.
If the fireplace has been flagged by a housing inspection, or if the home has an older clay-tile flue, a Level 2 camera inspection is the right call. A Level 1 is a visual check from the firebox and roof, but it can’t see cracks halfway down the flue. We recommend Level 2 for every Lackland AFB home with a gas fireplace connected to a chimney built for wood.
Technically, yes, but it’s a bad idea. Gas exhaust is cooler and wetter than wood smoke, and it condenses inside unlined or clay-tile flues, breaking down the mortar from the inside. Most base homes need a stainless liner before a gas unit can vent safely. Without one, you’re asking for CO leakage between the flue cracks.
Most repairs are completed in one visit, and we can usually schedule you inside a few days. Larger relining jobs may take a second day. If you have an inspection deadline, tell us when you call (903) 515-5079 and we’ll work the schedule around it.
