A chimney inspection in Alamo Heights typically costs $189 to $389 for a Level 1 visual check, while a Level 2 camera inspection runs $350 to $650 depending on the number of flues and access difficulty. Most inspections on older Alamo Heights homes take 60 to 90 minutes, and we schedule within a few days, not weeks. Call (903) 515-5079 for a free estimate and a written price before we ever set foot on your property.
We know the older homes here. Many Alamo Heights chimneys sit on 1920s through 1960s masonry construction with original clay flue liners that were never designed for decades of continuous use. That changes how we inspect, what we look for, and why a camera run matters more here than in a newer subdivision. Ruben Castellano has built our inspection team around that reality.
Why Alcott Chimney San Antonio Is Alamo Heights’s Preferred Chimney Inspection Company
Since 2002, we’ve worked on hundreds of Alamo Heights homes, from the brick Colonials along La Jara Boulevard to the stone cottages off Broadway. Homeowners here tend to be particular about who comes through the door, and we’ve structured our company around that exact concern. Every technician we send is background-checked, identity-verified through the Threshold Standard, and announced to you by name and photo before arrival. You’ll know exactly who is ringing the bell, and they’ll show a photo ID badge at the door. No exceptions.
Our Chimney Inspection team coordinates directly from our San Antonio office, so response time to Alamo Heights is consistently quick. When a homeowner on Encino Avenue calls about a smoky fireplace or a suspicious crack in the crown, we can usually have someone out within a few days. That speed matters when you’re trying to use the fireplace during a cold snap and something isn’t right.
Reviews from Alamo Heights customers consistently mention two things: the technician showing up when promised and the written report making sense without a dictionary. We send every inspection client a photo-documented report the same day, with plain-English explanations of what we found, what needs attention now, and what can safely wait. That last part matters because no Alamo Heights homeowner should be told they need a $4,000 reline without seeing the camera evidence to prove it.

Chimney Flue Inspection in Alamo Heights
A Chimney Flue Inspection in Alamo Heights is a close examination of the interior passageway that carries smoke and combustion gases up and out of your home. On the older masonry homes here, that flue is frequently an original clay tile liner from the 1940s or 1950s that has been quietly cracking for decades. We run a camera down the flue, document every gap and spall with photos, and tell you exactly what the liner condition means for safety and function.
A flue inspection in Alamo Heights typically runs $350 to $550 for a single-flue camera run. Homes with two or three flues, which are common in the larger estate-style properties near Cambridge Oval, run higher because each flue gets its own camera pass.
What the Camera Shows
A camera inspection of an unlined or clay-lined flue reveals the things a visual check from the top cannot: hidden gaps between tile sections, spalling where the clay surface has flaked away, and joints that have separated enough to let heat and gas reach the surrounding masonry. In Alamo Heights, we routinely find these conditions on original fireplaces that have been used for fifty or sixty winters.
When to Book One
Book a camera flue inspection before the first burn of the season, after any chimney fire, or as part of a home purchase. In Alamo Heights, we also recommend one before converting a wood-burning fireplace to gas logs, because the insert changes how heat and moisture behave inside the existing flue.
Chimney Fire in Alamo Heights
A Chimney Fire in an Alamo Heights home is what happens when creosote, the tar-like buildup that forms inside a flue, reaches ignition temperature and burns inside your chimney. The fire itself can be loud and dramatic, or slow and nearly silent. Either way, the heat can crack the clay liner, warp the damper, and send embers into the attic. After any chimney fire, even a small one, the chimney needs a full inspection before it’s used again.
Creosote builds fastest in flues that run cool, which is exactly what happens in the older uninsulated masonry chimneys common across Alamo Heights. When a cold snap hits and a homeowner burns four nights straight, that creosote can ignite. A post-fire inspection in Alamo Heights typically runs $300 to $450, depending on whether we’re running a camera and how many flues were involved.
What We Inspect After a Fire
After a chimney fire, we check the entire system: the firebox, the damper, the smoke chamber, the flue liner from top to bottom, and the crown. A chimney fire can crack the clay liner in places you cannot see from the ground, which is why a camera run is not optional after one.
Creosote Levels in Older Alamo Heights Fireplaces
In a 1950s Alamo Heights fireplace used every winter, we commonly find second-degree creosote, a hardened granular deposit that’s difficult to remove by brushing alone. Homes that burn unseasoned wood or run the damper partially closed can hit third-degree creosote, which is a hardened glaze that almost always requires mechanical removal. Both conditions are fire hazards and need professional attention.
Trusted Brands We Service in Alamo Heights
When a smoke chamber needs parging, we use HeatShield. When our clients in Alamo Heights need resurfacing or repair, we carry HeatShield, DuraFlex, and Gelco materials on our trucks for faster turnaround. We also install and service Olympia Chimney caps and dampers, which we keep in our local inventory for the custom setups common on older Alamo Heights homes. Using trade-spec materials means the repair lasts, and the manufacturer backs the product. When a customer needs a custom cap fabricated for a stone chimney on a tight tree-lined street, we order it the same day and usually have it installed within two weeks.

AfterCommon Chimney Inspection Problems We See in Alamo Heights Homes
- Original unlined flues with hidden gaps. Many 1920s through 1950s Alamo Heights fireplaces were built without a clay liner or with a liner that has since cracked. A Level 1 visual cannot see inside the flue wall, so these gaps go undetected until a Level 2 camera inspection finds them.
- Gas conversions left with the damper partially open. When a wood firebox is converted to gas logs, the original damper often stays partially open to vent the pilot. That opening lets humid Texas air into the firebox year-round, rusting the metal and encouraging first-degree creosote at the smoke chamber.
- Efflorescence and spalling on masonry crowns. Alamo Heights gets enough rain and humidity that water works its way into brick and stone crowns, leaving white efflorescence deposits and eventually causing the surface to flake away. Left alone, that spalling widens cracks and lets more water in.
- Custom spark arrestors overlooked due to hard ladder access. Narrow winding streets with mature oaks make ladder placement difficult on many Alamo Heights properties. Technicians who don’t want to fight the access often skip the cap and flashing inspection, which means missing flashing leaks go unrepaired for years.
Pricing for Chimney Inspection in Alamo Heights, TX
A Level 1 chimney inspection in Alamo Heights runs $189 to $289 for a single flue. A Level 2 camera inspection, which we recommend for any Alamo Heights home with an original flue or a recent gas conversion, runs $350 to $550. Homes with multiple fireplaces and flues, which are common in the larger properties near Terrell Hills and the estates off New Braunfels Avenue, run higher because each flue gets its own camera pass and report. We give every customer a written price before any work begins, and the inspection report with photos is included at no extra charge. If we recommend a repair, we show you the camera images that support it. You decide what gets done. Call (903) 515-5079 for a free estimate.

FAQs About Chimney Inspection in Alamo Heights
A 1920s Alamo Heights masonry chimney with a gas insert should be inspected every year, and we recommend a Level 2 camera inspection at least every other year. The original flue on a home that old was almost certainly built without a modern liner, and the gas insert changes the temperature and moisture profile inside that flue. Annual inspection catches liner gaps and rust before they become a carbon monoxide issue. Call (903) 515-5079 to schedule, and we’ll send a written quote before anything is booked.
Yes, and in fact that’s exactly what it’s for. A camera inspection is the only reliable way to see the interior of an unlined flue on an original Alamo Heights brick chimney. The camera shows gaps, missing mortar, and spalling that are otherwise invisible from the top or the firebox. We document everything with photos so you can see the condition with your own eyes. Call us at (903) 515-5079 for an inspection and photo report.
They do. Chimneys in Alamo Heights with custom spark arrestors often sit on steep roof pitches with tree branches nearby, which makes ladder access difficult. We check the arrestor for corrosion, bird nesting, and debris buildup, and we inspect the flashing where it meets the roofline. A standard drive-by or ground-level look will miss these issues. Our inspectors carry the right ladder equipment and take photos of the entire crown assembly. Call (903) 515-5079 and we’ll tell you exactly what we check.
In a 1950s Alamo Heights fireplace used every winter, we typically find second-degree creosote, which is a hardened, granular deposit that a standard brush cannot fully remove. Homes that burn green wood or partially close the damper overnight can develop third-degree creosote, a hardened glaze that requires mechanical removal. Both are fire hazards. If your fireplace gets used more than a few times a season, call (903) 515-5079 for an inspection and creosote assessment.
Alamo Heights humidity and periodic heavy rain push moisture into brick and stone masonry, and that moisture causes efflorescence and spalling over time. The crown, the mortar joints, and the flashing around the chimney are the most vulnerable points. Once water gets into the masonry, freeze-thaw cycles in winter can widen the cracks. An annual inspection catches these moisture issues before they require expensive repointing or relining. Call (903) 515-5079 for a free estimate.
