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.

Alamo Heights isn’t like the newer subdivisions spreading north of Loop 1604. The homes here were built when fireplaces actually heated rooms. A gas log set sitting in a 1930s firebox is a completely different repair than a prefab unit in a 2010s tract house. That’s the work we do every week, and we know these chimneys.
Why Alcott Chimney Sweep Is Alamo Heights’s Preferred Gas Fireplace Repair Company
Since 2002, we’ve worked on the kind of homes that line Broadway, Cambridge Oval, and Argyle Avenue: Tudor Revivals and Spanish Eclectics where the chimney is load-bearing masonry, not a metal box behind drywall. Alamo Heights homeowners call us because we’re the company that tells you the technician’s name and shows you their photo before the truck pulls up. Every person we send into your home has passed a background check and identity verification under the Threshold Standard, and they’ll show a photo ID badge at the door. No exceptions, no “we forgot the badge” line.
Ruben Castellano runs our operation, and his rule is simple: if the diagnosis can’t be explained plainly, it isn’t a diagnosis. That matters in Alamo Heights, where a gas fireplace repair often uncovers conditions in a 90-year-old chimney that no one warned you about when you bought the house. We give you a written price before work begins, and a written guarantee on every repair. If the repair fails within the coverage period, the second visit is free. That’s the 365-Day Done Right Promise, and it’s included. Not sold.
Our Gas Fireplace Repair Services in Alamo Heights
Gas Fireplace and Gas Log Set Repair
Most Alamo Heights calls start with a gas log set that won’t stay lit, soots the firebox, or smells faintly of unburned gas. We repair or replace thermocouples, thermopiles, gas valves, pilots, and burner assemblies. We service the brands installed in these homes over the past 40 years: Olympia Chimney, Famco, Copperfield, and vented sets from the major manufacturers. If the appliance is beyond repair, we’ll say so and show you why.
Level 2 Chimney Inspection for Converted Wood Fireplaces
Alamo Heights has a lot of original wood-burning fireboxes that became gas fireplaces in the 1980s and 1990s. A Level 2 inspection is the only way to know whether that conversion was done right. The February 2021 freeze cracked mortar joints across the area’s pre-WWII masonry, and those cracks change how a gas appliance drafts. We inspect the entire flue, the smoke chamber, the damper, and the firebox, and we give you a written report with photos.
Flue Liner Installation and Relining for Gas Appliances
The original Alamo Heights chimneys predate NFPA 211 liner standards by decades. A gas log set installed in an unlined or single-wythe clay-tile flue pulls combustion byproducts through cracks and into the mortar bed. We install DuraFlex stainless liners sized to the appliance, not the fireplace opening. Relining is the most common big-ticket repair we quote in this city, and we’ll show you the camera footage that justifies it before you spend a dollar.
Gas Fireplace Conversion and Insert Work
If your Alamo Heights fireplace is decorative and you want it functional, a gas insert is often the right answer. Inserts burn cleaner, seal tighter, and work in fireboxes that were never designed for open gas flames. We’ll measure the firebox, confirm the existing flue can support the insert, and quote the full job in writing before any work starts.

Trusted Brands We Service in Alamo Heights
We carry and install professional trade materials, not box-store substitutes. For Alamo Heights gas fireplaces, that means DuraFlex liner systems, Famco gas valves, Olympia Chimney components, and Copperfield accessories. Because we keep common parts stocked locally, most gas valve and pilot assembly replacements don’t wait on a parts truck from Dallas. Gas Fireplace Repair teams that quote cheap and install unknown-brand parts are the reason so many Alamo Heights fireplaces need a second repair within two years. We don’t do that.
Common Gas Fireplace Repair Problems We See in Alamo Heights Homes
- Sooting and weak draft in converted fireplaces. Older Alamo Heights fireboxes were sized for wood, not gas. Without a properly sized liner and a gas-log damper clamp, combustion byproducts condense in the smoke chamber instead of drafting up the flue. The soot on your firebox is the symptom; the cause is usually upstream.
- Post-Uri mortar cracking around the firebox and crown. Winter Storm Uri in February 2021 pushed water into thousands of masonry joints across Alamo Heights. When that water froze, it spalled the mortar. A gas appliance’s heat now travels through those cracks into the surrounding clay tile, which spalls further. We see this on re-inspection constantly.
- Failed thermocouples and gas valves on older log sets. Gas log sets installed in the 1990s are now 30 years old. Thermocouples fail, valves stick, and pilots won’t hold. These are routine repairs for us, and they typically cost $165 – $320 in Alamo Heights when the appliance is otherwise sound.
- Animal nesting in chimneys that sat unused for years. Alamo Heights’s mild winters mean a lot of fireplaces go years between lightings. That’s exactly the window when birds, squirrels, and raccoons move in. A gas fireplace lit over a nest is a real fire risk. We remove the nesting and cap the chimney when it’s safe to do so.
Pricing for Gas Fireplace Repair in Alamo Heights, TX
Here’s what Alamo Heights homeowners can expect to pay, based on the jobs we complete most often in this area:
- Service call and diagnostic: $85 – $120, waived if we do the repair
- Thermocouple or thermopile replacement: $165 – $240
- Gas valve replacement: $220 – $380
- Pilot assembly cleaning or replacement: $140 – $260

These ranges reflect Alamo Heights’s older housing stock. A 1935 Tudor on a street like Wildwood Lane has a taller flue run and older mortar than a 2005 build, so the liner quote sits higher. Every job gets a written price before work begins, and that price doesn’t change unless you approve a change order. Call (336) 863-3889 for an exact quote, and we’ll put it in writing.

FAQs – Gas Fireplace Repair in Alamo Heights
Almost certainly yes. The original masonry chimneys in Alamo Heights were built between the 1920s and 1950s, decades before NFPA 211 required flue liners sized to the appliance. A gas log set venting into an unlined or cracked clay-tile flue sends condensation and combustion byproducts into the mortar bed, which eats the joints over time. We’ll run a camera up the flue and show you exactly what’s there before we recommend a liner. If the flue is sound and sized correctly, we’ll say that plainly and you’ll only pay for the inspection. Call (336) 863-3889 to schedule one.
Sooting and odor in an older Alamo Heights fireplace almost always trace back to draft problems, not the gas log set itself. The original firebox was sized for wood, so a gas set burning without a proper damper clamp or liner can’t pull enough air up the flue. Combustion byproducts stall in the smoke chamber, condense, and eat the lime mortar, which makes the smell worse over time. The fix is usually a liner and damper correction, not a new log set. We’ll diagnose it with a camera inspection and explain the issue in plain terms.
Once a year. The National Fire Protection Association recommends annual inspection for all chimneys and venting systems, and that’s especially true in Alamo Heights, where the flues are 70 to 100 years old. Post-Uri mortar cracking, animal nesting, and slow deterioration from decades of disuse are all things we catch on annual inspections that would be expensive surprises later. A yearly inspection here typically runs $150 – $250, and it’s the cheapest insurance you’ll buy on a historic house.
Yes, extensively. The February 2021 freeze pushed water into thousands of mortar joints across Alamo Heights’s pre-WWII masonry, and when that water froze, it spalled the joints around fireboxes and chimney crowns. Many homeowners discovered the damage only when they tried to light their gas fireplace the following winter. If your Alamo Heights home went through Uri and you haven’t had a Level 2 inspection since, there’s a real chance the flue or firebox has cracks you can’t see from the living room. We find this on re-inspections all the time, and we’ll show you the camera footage.
Yes, but with legal limits. Chimney swifts are federally protected under the Migratory Bird Treaty Act, and they nest in uncapped masonry chimneys throughout Alamo Heights from roughly April through September. If we find an active nest during a repair, we’re required by law to stop work on that flue and reschedule until the birds fledge. We check for nesting as part of every inspection and can cap the chimney outside nesting season to prevent the problem entirely. If you’re hearing bird sounds during those months, tell us when you call and we’ll plan around it.
