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.

AfterFast, Reliable Chimney Sweep Across San Antonio
Most San Antonio chimneys sit dormant for nine or ten months, quietly collecting debris, animal nests, and moisture damage while the flue never gets warm enough to burn off the tar-like creosote that clings to its walls. Then a blue norther barrels down the Escarpment, temperatures drop 30 degrees in a few hours, and suddenly that neglected flue is the only thing standing between your family and a chimney fire. We’re Alcott Chimney Sweep, and we’ve been cleaning and inspecting San Antonio flues since 2002. Call (336) 863-3889 and we’ll have a background-checked, identity-verified technician scheduled before the first cold front hits.
Key Takeaways:
- A standard chimney sweep in San Antonio runs $189 – $319 before any repairs, depending on flue type and creosote stage.
- Rural wood stoves burning only during cold snaps still build second-degree creosote faster than homeowners expect; annual sweeping is the safe interval, not optional.
- You’ll know your technician’s name and see their photo before we arrive, and they’ll show a photo ID badge at the door. Every time.
- Written price before any work begins. Written guarantee on every repair. Free second visit if a repair fails within the coverage year.

This is the Threshold Standard, not an optional upgrade, and every single customer gets the technician’s name and photo sent before the visit. When the van shows up, the person at the door matches the person you were told to expect. No exceptions.

Ruben Castellano runs Alcott the way a neighbor would: show your work, stand behind it, and answer the phone when someone calls.
Chimney Sweep Certified in San Antonio
Chimney Sweep Certified work in San Antonio means more than running a brush up a flue. It means a technician who understands that San Antonio’s soft limestone chimneys erode differently under flash-flood rains and rare freeze-thaw events than standard brick does, and who knows what that means for your mortar joints before you light the first fire of the season. A standard sweep in San Antonio typically runs $189 – $319 depending on flue height, creosote stage, and whether we’re dealing with an open masonry fireplace or a prefab zero-clearance unit. The job takes about an hour to ninety minutes, ends with a visual check of the firebox, damper, and chimney cap, and leaves you with a written report of what we found.
Creosote Removal That Matches How San Antonio Actually Burns
When a San Antonio wood stove only runs during blue norther cold snaps, the flue never warms evenly. The house has been cold for months, the fire gets cranked high to compensate, and first-degree creosote forms quickly in a flue that’s not used to sustained heat. If that glaze hardens into second-degree creosote, a standard brush won’t cut it on its own. We use chemical creosote removers and follow-up sweeps when needed, and we’ll tell you exactly what stage your buildup is in before we quote the work.
Annual Sweep Before the First Cold Front
The smartest San Antonio homeowners schedule their sweep in October or early November, before that first sharp cold front triggers a rush of emergency calls. We service all of San Antonio, including the rural properties along the 281 corridor and out west toward Alamo Ranch. Dispatch and scheduling are coordinated from our Miami office, but our crews serve San Antonio locally, which means your slot isn’t competing with calls from three counties away.
Gas Fireplace Cleaning in San Antonio
Gas Fireplace Cleaning in San Antonio is a different animal than a wood flue sweep, and skipping it because “it’s just gas” is a mistake we see constantly in the 1980s – 2000s suburban homes around Stone Oak and Alamo Ranch. Those prefab zero-clearance fireplaces and gas-log inserts shift the service focus away from creosote and toward venting integrity, burner condition, and firebox liner inspection. A gas fireplace cleaning in San Antonio typically runs $129 – $229, and it includes cleaning the burner assembly, inspecting the venting run, checking the firebox liner for hairline cracks, and verifying the pilot assembly ignites cleanly.
Venting Integrity for Gas Logs
San Antonio’s long idle season lets dust and debris settle inside gas-log venting runs, and when the first cold night hits, that restriction can push combustion byproducts back into the house. We check the entire vent path and clean what needs cleaning. If the liner shows hairline cracking from years of heat cycling, we’ll show you the camera footage before we recommend anything.
Firebox Liner Inspection Included
Every gas fireplace cleaning includes a liner inspection with a camera. You’ll see what we see. If the liner is sound, we’ll tell you plainly that it can safely wait. If it’s not, we’ll show you exactly where the failure is and quote a repair using professional-grade materials like HeatShield or Olympia Chimney, not a patch job.
Trusted Brands We Service in San Antonio
Alcott installs and services professional trade brands that chimney professionals actually specify: DuraFlex liner systems, HeatShield resurfacing, Gelco, Olympia Chimney, and Famco. When a San Antonio repair calls for a new flue liner or a resurfaced smoke chamber, we’re not improvising with box-store substitutes. We carry these materials for fast turnaround on San Antonio jobs. That matters when you’re trying to get a wood stove back online before the next cold front, not three weeks after it passes.
Common Chimney Sweep Problems We See in San Antonio Homes
- Rural wood stoves with second-degree creosote. We were out on a rural property near the old U.S. 281 corridor outside San Antonio where a freestanding wood stove had been the family’s primary heat for three seasons. Our tech pulled the baffle and ran the flue liner brush, then hit a stubborn glaze patch in the smoke chamber that had to be addressed with a chemical creosote remover and follow-up sweep. The homeowner had skipped inspections since the install because “we only burn during cold snaps.” That’s exactly how second-degree creosote creeps toward third-degree.
- Uncapped chimneys collecting debris during the dormant season. San Antonio’s mild winters mean most flues sit inactive for months, and an uncapped chimney is an open invitation for leaves, nesting animals, and moisture. By the time a tech is called, first-degree creosote has hardened while mortar joints have started spalling. The firebox and chimney crown need more than a sweep at that point.
- Pre-1940s limestone chimneys in King William, Monte Vista, and Mahncke Park. These historic San Antonio homes were built with soft local limestone and lime mortar that erodes measurably faster than standard brick under the city’s episodic flash-flood-level rainstorms and rare but sharp freeze-thaw events. Moisture intrusion and spalling mortar joints are the dominant deterioration mechanism here, not creosote.
- Prefab fireplaces in Stone Oak and Alamo Ranch with hairline liner cracks. The 1980s – 2000s suburban expansion on the north and west sides of San Antonio is heavily stocked with zero-clearance fireplaces and gas-log inserts. Years of heat cycling plus long idle periods cause hairline cracks in the flue liners. A rushed inspection misses these. Our camera inspection doesn’t.

FAQs About Chimney Sweep in San Antonio
Once a year, no exceptions. That’s the short answer. Even if your wood stove only fires up during three or four blue norther events each winter, the flue never warms evenly because the house has been cold all season. That uneven heating promotes first-degree creosote formation faster than most homeowners expect, and if it glazes into second-degree creosote, a standard brush won’t remove it. Annual sweeping costs $189 – $319 in San Antonio, which is far less than a chimney fire or a failed flue liner. Call (336) 863-3889 and we’ll get you on the schedule before the next cold front.
If Chimney Swifts have an active nest in your chimney, we cannot legally sweep it or cap it until the birds leave. These are federally protected migratory birds, and the Migratory Bird Treaty Act prohibits disturbing active nests. They typically depart by late September or early October in San Antonio. The smart move is to schedule your sweep and cap installation for after that window, or get a cap installed in early spring before nesting season begins. A capped chimney means no swifts, no debris, and no moisture damage. Call us and we’ll explain the exact timing for your property.
Yes. A wood stove flue is typically a stainless steel liner inside a masonry or prefab chimney, and it accumulates creosote differently than an open fireplace flue. Wood stoves burn hotter and more efficiently, but they also pull more creosote-forming gases through a narrower flue path. The sweep itself requires different brushes and more attention to the baffle, the connector pipe, and the smoke chamber. A standard open-fireplace sweep in San Antonio runs $189 – $259, while a wood stove sweep with a liner typically runs $259 – $319. The extra cost reflects the additional disassembly and the more aggressive creosote stages we usually find.
Because your chimney is likely built from the soft local limestone and lime mortar common in San Antonio’s pre-1940s inner neighborhoods like King William, Monte Vista, and Mahncke Park, while your neighbor’s brick house is, well, brick. Limestone and lime mortar erode measurably faster under San Antonio’s episodic flash-flood-level rainstorms and rare but sharp freeze-thaw events. Moisture gets into the mortar joints, freezes on those rare cold nights, and expands the cracks. Over a few seasons, you get spalling: the visible flaking and crumbling of the masonry surface. A Level 2 inspection will show you exactly how far the damage has progressed and what needs to be done about it.
A Level 1 inspection is a visual check of the accessible portions of the chimney, interior and exterior. It’s included free with every San Antonio sweep. A Level 2 inspection adds a camera run down the full flue length and is required when you’re changing the appliance, selling the home, or after a chimney fire. It runs $125 – $250. A Level 3 inspection involves removing masonry or other construction materials to access hidden areas, and it’s only needed when a Level 2 reveals serious structural concerns. Most San Antonio homeowners need a Level 1 with their annual sweep, and a Level 2 if their chimney cap is missing or if they’ve bought a home with an unknown service history. Call (336) 863-3889 and we’ll tell you which one fits your situation; the quote is free.
