Chimneys in San Antonio: an amenity, not a furnace
San Antonio is mostly an electric-heat city. In the city itself 70.2% of occupied homes heat with electricity and 27.8% with utility gas, while wood as a primary heat source rounds to zero (ACS 2024 5-year). CPS Energy serves about 399,000 natural gas customers. The typical request is a gas log set in an older masonry firebox, or a fireplace lit a few dozen evenings a year.
The heating window is short. NOAA’s 1991–2020 normals for San Antonio International Airport show 1,438.4 heating degree days a year, 72% of them in December through February, and 14.0 nights at or below 32 °F. The median first freeze is November 28. The rest of the year is warm and wet: 32.38 inches of rain, May the wettest month at 4.40 inches, and 17.7 days at or above 100 °F.
So local chimney problems are usually moisture and idle flues rather than heavy creosote: rain down an uncapped flue, cracked crowns, rusted chase covers and dampers, and animals in a chimney nobody has used since February.
Two kinds of fireplace, two kinds of job
The city’s median home was built in 1985; 29.2% of units predate 1970 and 5.1% predate 1940 (ACS 2024 5-year). Inside Loop 410, Monte Vista (ZIP 78212, median year built 1949), Alamo Heights (1950) and Terrell Hills (1957) hold the 1920s–1950s brick and limestone houses with masonry chimneys and clay flue tiles, and gas-heat shares there run high at 47.6% and 57.1%. The 1980s–2000s north-side subdivisions are where prefab (factory-built) fireplaces with metal chase covers are common, and those covers are now decades old. Sweeps and caps are priced differently for the two, so say which you have.
Historic districts and permits
King William (the city’s first historic district, 1968), Monte Vista (1975) and Dignowity Hill (1983) sit under the Office of Historic Preservation. Exterior modifications and repairs on a property with historic zoning need a Certificate of Appropriateness. Sweeping, inspections, caps and dampers need no City of San Antonio permit we could find; dryer-duct, mechanical and gas work are permitted trades; and whether a chimney rebuild or reline needs a building permit is not stated on the City’s pages, so the contractor confirms with Development Services.
After a hard freeze
Freezes are rare but sharp. The airport fell to 9 °F on February 15, 2021 and stayed below freezing for 4 days 12 hours during Winter Storm Uri; it hit 18 °F on January 17, 2024; it saw light snow and 24 °F on January 21–22, 2025; and the winter of 2026 bottomed out at 20 °F. Crown cracks, spalling brick and flashing leaks show up after events like these; a masonry and flashing quote is the usual next step.
Live oaks and chimney swifts
Live oaks drop their old leaves in late January through March, and an uncapped flue under that canopy collects litter. Chimney swifts return to Texas from mid-March and roost in September; they are protected under the Migratory Bird Treaty Act, so an active nest is left alone and the flue is swept and capped after the birds leave, generally late October to February (Texas-wide guidance). Caps and animal exclusion follow that calendar.
Where we arrange quotes
San Antonio, the enclave cities inside Loop 410, and the Hill Country and Metrocom towns in Comal, Guadalupe and Kendall counties. All service areas.
Chimney sweep questions, answered
More on the FAQ page.
How much does a chimney sweep cost in San Antonio?
Typical national ranges from Fixr (2025) and Angi via Bob Vila (2023) put a chimney sweep at about $130–$380, with a gas fireplace flue at $85–$250 and a camera inspection adding roughly $50–$75. Local companies advertise starting prices from roughly $99 to $195, which usually exclude prefab units, extra flues and repairs.
Does a gas fireplace or log set need a chimney sweep?
Gas burns cleaner than wood, but the flue still needs a yearly look. CSIA summarizes NFPA 211 as calling for inspection at least once a year for soundness, freedom from deposits and correct clearances, with cleaning and repairs done if necessary. In a city where 27.8% of homes heat with utility gas (ACS 2024 5-year), gas log sets in older masonry fireboxes are a common request.
How often should a San Antonio chimney be swept or inspected?
Once a year, even if the fireplace is rarely lit. CSIA’s summary of NFPA 211 applies the annual inspection to unused chimneys too, because animals may nest in the flue or other deterioration may occur. Most local fireplaces sit idle March through November, so moisture, debris and birds are the usual findings.
Are chimney sweeps licensed in Texas?
No. Texas has no chimney-sweep, masonry, roofing or general-contractor license; TDLR’s program list includes none of them. The credentials that exist are private: CSIA Certified Chimney Sweep and NFI certification, which can be verified on csia.org and nficertified.org. Ask any company for those, proof of insurance, a written scope with photos and, for repair work inside San Antonio city limits, a City Home Improvement Contractor registration.
