The oldest chimneys in the San Antonio market
Alamo Heights is a 1.84-square-mile city of 7,492 people (ACS 2024 5-year), almost completely surrounded by San Antonio, with the area's densest block of pre-war houses. The median home was built in 1950; 32.9% of units date from before 1940 and 64.7% from before 1970. Building began in the 1890s and the city incorporated in 1922 with zoning that held houses to two stories, so most chimneys here are short masonry stacks on low rooflines under live oaks.
Those brick and stucco chimneys with clay flue tiles are now 75 to 100 years old. The usual findings are cracked crowns, spalled brick, loose flashing where stucco meets a tile roof, rusted dampers and shifted flue tiles rather than heavy creosote. A Level 2 camera inspection shows the inside of a tile liner, and crown, flashing and masonry repair is the most common quote request here.
Gas logs, idle flues and a short burning season
Alamo Heights splits almost evenly between utility gas (47.6%) and electric (48.1%) home heating in the ACS 2024 5-year house-heating-fuel series, one of Bexar County's higher gas shares. That means gas log sets in original 1930s and 1950s fireboxes, lit on the roughly 14 nights a year the airport drops to freezing. NOAA's 1991 to 2020 normals put 72% of the heating degree days in December through February, so flues sit idle from March to November, through May's 4.40 inches of rain.
An uncapped idle flue under live oaks collects leaf litter and ball moss, and chimney swifts, protected under the Migratory Bird Treaty Act, use open flues from mid-March until the September roosts disperse. A screened cap and a sweep scheduled for late October to February (Texas-wide guidance) covers both. Homeowners with gas sets can read about gas fireplace and log-set service too.
Freeze damage: the February 2021 storm held the airport below freezing for four and a half days, bottoming at 9 °F on February 15. Water in a cracked crown or open mortar joint expands in an event like that.
Permits, preservation and what to ask a company
Alamo Heights issues its own permits. A council agenda item showed the city adopting the 2021 IRC, IMC, IFGC and IFC with the 2020 NEC, but the final ordinance was not confirmed, so: permits vary by city; your contractor confirms. Unlike Monte Vista inside San Antonio, Alamo Heights has no historic district, so an exterior chimney rebuild needs a city permit but no Certificate of Appropriateness.
Texas has no chimney-sweep, masonry or roofing license, so ask any company for CSIA or NFI certification (verify on csia.org or nficertified.org), proof of insurance and a written scope with photos.

Alamo Heights chimney FAQ
How often should an older Alamo Heights masonry chimney be swept?
The CSIA summary of NFPA 211 calls for an inspection at least once a year for soundness, freedom from deposits and correct clearances, with cleaning and repairs done if necessary. For a 1920s to 1950s brick chimney burning a few dozen fires a winter, that usually means a Level 1 inspection each fall and a sweep when deposits turn up.
Do gas logs in an old Alamo Heights fireplace still need service?
Yes. Roughly half of Alamo Heights homes heat with utility gas (ACS 2024 5-year), and many original fireboxes now hold gas log sets. The flue still needs a cap and periodic inspection because rain, leaves and animals get in whether or not wood burns. Gas line work is done only by Texas-licensed plumbers, so ask who will touch the gas.
Does Alamo Heights require a permit for chimney repair?
Alamo Heights is its own city with its own building department, so City of San Antonio rules do not apply. A council agenda item adopted the 2021 International codes, but the final ordinance was not confirmed, so permits vary by city and your contractor confirms before a rebuild, reline or gas work. There is no historic-district review here.
What does a chimney sweep cost in Alamo Heights?
Typical national ranges from Fixr (2025) and Angi via Bob Vila (2023) put a chimney sweep at $130 to $380, a Level 2 camera inspection at $150 to $1,000, crown repair at $750 to $1,000 and tuckpointing at $500 to $2,500.
