Terrell Hills isn’t like the newer subdivisions around San Antonio. Your home likely dates to the 1920s through 1940s, and your gas fireplace probably vents into a chimney that was built for wood burning when the house went up. That matters more than most people realize. We’ve worked on enough pre-war masonry stacks in Terrell Hills to know what hides behind the damper plate, and we’ll show you camera footage from inside your own flue before recommending our Chimney Repair in Terrell Hills.
Why Hadley Chimney San Antonio Is Terrell Hills’s Preferred Gas Fireplace Repair Company
Hadley Chimney San Antonio has been in business since 2003, and our Gas Fireplace Repair team knows Terrell Hills homes specifically. The housing stock here is older, custom built, and often has multiple fireplaces tied to chimneys that were never designed for gas appliances. That’s not a problem for us. It’s what we’re built for.
Cory Mitchell leads our crew, and the standard he set from day one hasn’t changed: every repair gets a written guarantee, and if it fails within 365 days, we come back free. That’s the 365-Day Done Right Promise, and it applies to every gas valve, thermocouple, and flue liner we touch in Terrell Hills.
We’re part of the Relay Home Co. family, which means Terrell Hills customers get the Relay Visibility Guarantee on every visit. Live arrival tracking, before-and-after photos, and a written price before the work starts. No four-hour windows. No vague verbal quotes. You’ll know who’s coming and what it costs before the van pulls up.
Our technicians arrive in uniform, background-checked, and the phone line is answered by a human 24/7. When a gas fireplace won’t light in January and the house is cold, you don’t want a callback queue. You want an answer. We give you one.

Our Gas Fireplace Repair Services in Terrell Hills
Flue Liner Inspection and Relining
This is the big one for Terrell Hills. Your original clay tile liner has survived decades of San Antonio freeze-thaw cycles, and clay tiles don’t flex. They crack. Once they crack, gas exhaust can seep into wall cavities instead of venting outside, which is a carbon monoxide risk that no amount of log cleaning will fix. We scope every flue with a camera and reline with DuraFlex when the footage shows it’s needed.
Damper Replacement for Gas Fireplace Conversion
If your Terrell Hills home was converted from wood to gas at some point, the original damper is often still in place and rusted half open. That’s a problem, because a gas fireplace needs a damper that seals correctly when the unit is off, not one that lets conditioned air pour up the chimney all summer. We replace and reseat dampers so the fireplace actually drafts and the house doesn’t leak air.
Chimney Crown and Flashing Repair
Terrell Hills gets real rain, and your chimney crown is the concrete cap that keeps that rain out of the masonry. On older homes, cracked crowns let water into the brick, which then freezes during our occasional winter cold snaps and spalls the face off the chimney. We repair crowns and flashing as part of the gas fireplace service, because a leaking chimney will eventually ruin the firebox below it.
Gas Valve, Thermocouple, and Log Set Replacement
Sometimes the chimney is fine and the problem is in the firebox: a thermopile that won’t generate enough millivolts, a gas valve that won’t hold pressure, or ceramic logs that have finally cracked apart. We carry Famco and Copperfield parts to handle these repairs same-day in Terrell Hills, and we’ll explain what failed before we replace it.

Trusted Brands We Service in Terrell Hills

We stock the right parts locally and we can get them to your door within days, not weeks. Whether your gas logs are a newer set or an original conversion, we can identify the brand, source what’s needed, and get it running.
Common Gas Fireplace Repair Problems We See in Terrell Hills Homes
- Cracked clay tile liners from freeze-thaw cycles. The original clay flue tiles in 1920s-1940s Terrell Hills chimneys crack after decades of our humid, occasionally freezing winters. The result: exhaust gas bleeding into wall cavities, not out the top of the chimney. We see this on nearly every unlined or clay-tile chimney we open up.
- Closed-off basement flues drafting backward. Many Terrell Hills pre-war homes have dual-flue chimneys, one serving a living room fireplace and one a basement fireplace that was sealed off decades ago. When a gas insert is added upstairs, the abandoned flue can pull air backward and send old creosote smell or even exhaust into the living space. Tracing and correcting that draft is a repair we perform regularly in this neighborhood.
- Spalling brick from water intrusion at the crown. Cracked chimney crowns and failed flashing let water soak into the masonry. When it freezes, the brick face pops off in flakes, a process called spalling. Left alone, the chimney structure weakens and the firebox below gets moisture damage that ruins gas logs and burners.
- Creosote from previous wood use igniting after gas conversion. A lot of Terrell Hills fireplaces were wood burners for decades before someone converted them to gas. The smoke chamber still has third-degree creosote, which is flammable tar buildup. If it ignites, you have a chimney fire. Before we service any gas fireplace in an older home, we check what’s coating the smoke chamber.

FAQs – Gas Fireplace Repair in Terrell Hills
No. If the fireplace hasn’t been used in years, the flue needs to be camera-scoped before you light anything. In Terrell Hills, pre-war dual-flue chimneys frequently have a basement flue that was sealed decades ago, and the active flue can be cracked or obstructed without any visible sign on the firebox. We’ll scope it, show you the footage, and tell you what’s safe.
That smell is usually creosote in the smoke chamber or a draft reversal from a sealed-off second flue pulling stale air into the room. Humid San Antonio summers make creosote absorb moisture and off-gas, and the smell gets stronger. We find the source with a camera, then clean and correct the draft. Call (254) 276-4116 to schedule an inspection.
In these older masonry homes, the usual cause is a failing thermopile or a gas valve that’s losing pressure. But we also see flue blockages from spalled clay tiles that snuff the pilot light. The only way to know is to test the millivolt output and scope the flue. We do both on the first visit.
Only if the camera shows the existing masonry is structurally sound and the flue is properly sized for the gas appliance. Many Terrell Hills chimneys are unlined or have original clay tiles that are cracked, and in those cases, a partial repair is unsafe. We’ll show you the footage before we recommend relining, and we won’t push a reline if the flue is actually fine.
Terrell Hills work must comply with local building codes, and any gas appliance installation or major venting change typically requires a permit and inspection. We handle the chimney side of the conversion, documenting the flue condition and making sure the venting meets code. Call (254) 276-4116 and we’ll walk you through the process for your house.
A standard chimney sweep in Terrell Hills runs $180 to $260 for a single flue. If your home has the dual-flue pre-war setup, expect $280 to $420 for both. The sweep includes a Level 1 inspection and photo documentation. Call (254) 276-4116 to book, and we’ll confirm the price before we arrive.
How We Approach a Terrell Hills Gas Fireplace Repair
Here’s what happens when you book. We arrive in a tracked window, not a four-hour guess. The tech introduces themself, lays down drop cloths if needed, and starts with a visual check of the firebox and controls. Then we scope the flue with a camera, and you watch the footage with us. Anything we recommend, you’ll see the reason for with your own eyes before we give you a written price. That’s the only way we work, and it’s the same process whether we’re on Geneseo Road or Wiltshire Avenue.
A while back, on a 1930s masonry home off Geneseo Road, we found the gas logs drafting into a clay tile flue that had lost most of its mortar joints behind a closed-off basement damper. Our crew scoped it with a camera, showed the homeowner the live footage, and lined the active flue with DuraFlex before restoring the fireplace. Had we not scoped it, that house would have been venting exhaust into a wall cavity. This is the kind of hidden problem that’s common in Terrell Hills, and it’s exactly why we don’t recommend repairs without camera evidence from inside your own flue.
