Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterFast, Reliable Gas Fireplace Repair Across New Braunfels
A gas fireplace repair in New Braunfels typically costs $145 – $420, depending on what’s actually wrong with the unit, and most issues can be diagnosed the same day. That’s a real range, not a guess: a thermocouple or thermopile replacement sits at the low end, while a chase cover, liner, or full venting diagnostic lands higher. If your fireplace won’t light, shuts off mid-burn, or smells like exhaust inside the house, call us at (336) 863-3889. We serve every corner of New Braunfels, from the limestone homes near downtown to the newer subdivisions off Klein Road and FM 306, and we’ll give you a written price before any repair begins.
Why Alcott Chimney Sweep Is New Braunfels’s Preferred Gas Fireplace Repair Company
Ruben Castellano has us doing one thing other gas fireplace repair companies in New Braunfels don’t: we tell you exactly who is coming to your door before the truck pulls up. Every technician we send is background-checked, identity-verified, uniformed, and sent to you by name and photo ahead of the visit. They carry a photo ID badge and they’re required to show it at the door, every single time. No exceptions. If you’re home alone with young kids or you’re just cautious about letting a stranger inside, that matters.
We’ve been in this trade since 2002 as part of the Threshold Group family of home-service companies. Around New Braunfels, that translates to working in homes built in 1895 and homes built in 2016, understanding the differences, and not treating either one like a generic box. The 365-Day Done Right Promise backs every repair in writing: if the work fails within the coverage period, the second visit is free. That’s not an upsell. It’s just how we operate.
Our Gas Fireplace Repair Services in New Braunfels
Gas Fireplace Venting and Draft Diagnosis
In New Braunfels, especially in attached townhome and duplex rows, a fireplace that won’t stay lit is often a venting problem, not an ignition problem. We run draft tests, camera the flue, and check termination caps to see what’s actually moving air. The fix might be a liner isolation, a cap replacement, or a simple adjustment. You’ll know before we touch a screwdriver, because the price is written down first.
Chase Cover and Cap Replacement
The humid air rising off the Guadalupe and Comal Rivers is rough on galvanized steel. We replace rusted chase covers with properly measured, sealed units, and we install chimney caps that keep rain and critters out. If your Gas Fireplace Repair team in New Braunfels finds a warped firebox floor from standing water, we’ll show you the camera footage before recommending anything.
Level 2 Inspection for Shared-Flue Properties
If you live in a New Braunfels townhome or duplex where multiple units share a masonry stack, a Level 2 inspection is the only way to know what’s venting where. Camera down the flue. Check the firebox. Verify terminations. We document everything in a photo report you keep. When your neighbor’s furnace shares your stack, this inspection is the difference between guessing and knowing.
Thermocouple, Thermopile, and Ignition Repair
Pilot lights that won’t hold, burners that click but never catch, flames that die after ten minutes. These are the most common gas fireplace repairs in New Braunfels, and they’re usually straightforward for a technician who knows the unit. We identify the exact part, explain what it does in plain English, and get it replaced same-week in most cases.

Trusted Brands We Service in New Braunfels
We work with professional trade materials, not box-store substitutes. When a New Braunfels home needs a liner, we install DuraFlex systems sized to the flue and the appliance. For firebox repair on factory-built units, we use HeatShield resurfacing. For masonry work on historic limestone chimneys near downtown, we use materials like Gelco and Olympia Chimney. We stock common repair parts locally so many New Braunfels jobs are finished in a single visit, and we service what these brands actually require: proper clearances, proper terminations, proper draft.
Common Gas Fireplace Repair Problems We See in New Braunfels Homes
- Cross-contamination in shared or adjacent flues. A neighbor’s furnace or water heater vents into the same stack, stealing draft and possibly pushing exhaust back into your firebox. This is the single most common hidden problem in New Braunfels’s attached housing rows.
- Rust-through on builder-grade galvanized chase covers. Five to seven years of river-valley humidity is enough. Water pools inside the chase, the firebox floor warps, the damper seizes, and the homeowner thinks the unit is broken when the real problem is the roof.
- Sticky second-degree creosote from short, low-temperature fires. New Braunfels cold snaps hit hard and fast after long mild stretches. The fire doesn’t burn hot enough, and the byproduct is concentrated inside the flue. Stage 2 creosote is tar-like and it doesn’t brush out easily.
- Freeze-thaw spalling on historic limestone chimneys. The original mortars in downtown’s German-settler homes were never meant for repeated freeze-thaw cycles. The joints open up, moisture gets in, and the chimney’s structural integrity quietly degrades until a Level 2 inspection finds it.
In Veramendi, a homeowner’s gas fireplace kept shutting down after a few minutes. Our tech pulled the vent cap on the shared chase and found the neighbor’s furnace flue venting into the same stack, recirculating exhaust and tripping the oxygen depletion sensor. We installed a correctly sized DuraFlex liner with a sealed top plate and a new chimney cap to isolate the two appliances, and the fireplace has run clean ever since. That’s not an unusual find in the subdivisions ringing New Braunfels, it’s what happens when builder-grade venting meets humid river air.

FAQs – Gas Fireplace Repair in New Braunfels
Yes. If your neighbor’s furnace or water heater vents into the same masonry stack as your gas fireplace, the exhaust can back up into your firebox, starve the flame of oxygen, and trigger the safety shutoff. When the shared stack can’t handle both appliances, the fix is usually a properly sized liner to separate the flues, plus a sealed top plate. We’ve seen this exact problem in attached New Braunfels townhomes and duplexes, and the camera inspection shows it clearly. Call (336) 863-3889 if your fireplace won’t stay lit and you share a wall.
The most common reason is the chase cover. In New Braunfels subdivisions like Veramendi, builder-grade galvanized chase covers routinely rust through in five to seven years from the river-valley humidity. Water gets inside, warps the firebox floor, seizes the damper, and the fireplace shuts down. The unit looks new from the outside because the damage is hidden under the cap. We pull the cap, show you the camera footage, and replace the cover and any corroded components. Call for an inspection and we’ll tell you exactly what’s happening under there.
Gas fireplaces don’t produce creosote the way wood fires do, but they still produce acidic condensation inside the flue and they still need an annual inspection, especially in New Braunfels. The humid air accelerates liner corrosion, and any venting restriction, whether from a rusted damper, a collapsed cap, or a bird nest, can send carbon monoxide into the house. A yearly inspection catches that before it becomes a problem. We recommend it for every gas fireplace we service in the city.
That’s Stage 2 creosote, and New Braunfels’s weather pattern practically manufactures it. Mild winters mean most fires are short and low-temperature, which produces tar-like creosote that clings to the flue walls instead of burning off. A few Feburary 2021-style cold snaps concentrated into a week is exactly the type of burning that deposits second-degree creosote fast. If you can see or smell it, the flue needs professional attention before another fire. Call us and we’ll inspect it.
Yes, but the approach is different from a suburban chase unit. Historic limestone masonry chimneys near downtown New Braunfels often have original clay flue liners that are cracked or missing entirely, and the soft limestone mortar joints have spalled from freeze-thaw cycles. The fix usually involves a properly sized liner installed inside the existing flue, plus tuckpointing on the masonry. We use DuraFlex liners and masonry materials specified for soft Texas limestone, and we’ll show you the camera footage before quoting any work.
