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
A standard chimney sweep in San Antonio runs $189 – $329 for a typical wood-burning fireplace, and most jobs are done in 60 to 90 minutes. That price includes the full sweep, a camera scan of the flue liner, and a photo report you keep. If you live anywhere from Alamo Heights to Helotes, call (830) 251-4560 and we’ll give you a written price before any tool comes off the truck.
We know San Antonio chimneys because we work on them every week. The 1920s bungalows off Broadway, the 1970s ranches in Castle Hills, the newer builds out toward the Dominion – each one brings different liner materials, different creosote patterns, and different questions. Our Chimney Sweep team serves the entire metro, and dispatch runs from our San Antonio office, so you won’t wait on a crew driving in from another county.
Why Flint Chimney Sweep Is San Antonio’s Preferred Chimney Sweep Company
Hank Delano runs our San Antonio operation, and he runs it under The Garrison Standard: every job gets a written price first, every repair carries the 365-Day Done Right Promise in writing, and every technician shows up background-checked and in uniform. That’s the whole pitch. You know the price before we start, you know what’s covered for a full year, and you know who’s walking through your door.
Our San Antonio customers tend to say the same thing after a service call: the flue liner photos told them more than any other sweeper ever had. That matters here specifically because so many San Antonio chimneys are masonry with clay tile liners. Our camera work shows you exactly what’s happening inside – not a verbal guess, not an upsell pitch. A photo report.
Phones are answered by a live person 24 hours a day, seven days a week. When you call (830) 251-4560 at midnight because you smelled smoke after a cold front moved through, you get a person. No voicemail tree, no “we’ll call you back Monday.”
Chimney Sweep Certified in San Antonio
Chimney Sweep Certified in San Antonio means the full sequence, not a brush-and-go: we sweep the flue liner, remove creosote and soot from the firebox and smoke chamber, check the damper, and then run a camera up the liner so you can see the condition of the clay tile or metal with your own eyes. A standard sweep in San Antonio runs $189 – $329 depending on flue height, creosote load, and whether there’s a cap or spark arrestor needing attention. The written price is delivered before any work begins, so the number you approve is the number on the invoice.
Creosote and Soot Removal
Creosote builds differently in San Antonio than it does in wetter climates. Our long dry spells and the sudden cold snaps that push fireplaces into heavy use for a week or two at a time create hard, flaky first-degree creosote that can ignite if it’s left to build. Soot removal is part of every sweep, and the camera scan confirms the liner is clear, not just that it “looks okay” from the top.
Annual Sweep and Inspection
An annual sweep is what most San Antonio homeowners schedule before burning season begins in late November. We clean the flue and check the chimney cap, crown, damper, and firebox. If the camera shows cracked tiles or spalling mortar, you get a straight answer on whether it can wait or needs attention soon. No pressure. The photo report tells the story.
Gas Fireplace Cleaning in San Antonio
Gas Fireplace Cleaning in San Antonio is not the same job as sweeping a wood-burning flue, and doing it wrong does nothing for your venting. A gas fireplace service here runs $149 – $249 and includes cleaning the glass, checking the burner and pilot assembly, inspecting the venting, and following the manufacturer’s service schedule for the unit you have. Many San Antonio homes built since the early 2000s in areas like Stone Oak and Alamo Ranch run gas inserts or gas log sets that get ignored for years, and we see the results: sooted glass, lazy flames, and venting that hasn’t been checked since the house was bought.
Venting and Manufacturer Service
The actual risk with a gas fireplace is carbon monoxide, not creosote. If the venting is compromised or the burner is running rich, you may not smell anything – which is exactly why the service matters. We check the flue, the termination cap, and the combustion air path, then note anything off in the written report.
Dust and Debris Removal
Gas logs collect dust, pet hair, and the fine grit that San Antonio’s dry, windy months push into a home. We clean the logs, the burner pan, the pilot shield, and the glass. It’s a straightforward job, but it makes a real difference in how cleanly the fireplace burns through the winter.
Trusted Brands We Service in San Antonio
Flint Chimney Sweep works with professional-grade chimney materials including HeatShield, Olympia Chimney, and Famco. If your San Antonio home has a ceramic-coated flue system, a stainless steel cap, or a liner that needs repair, those are the products we specify by job – not by whatever’s left in the warehouse. For local customers, that means faster turnaround when a part does need ordering, and a repair that’s built on a manufacturer’s tested system rather than a patch. We stock common San Antonio repair components in our metro office, so many repairs don’t wait on shipping at all.
Common Chimney Sweep Problems We See in San Antonio Homes
- Cracked clay tile liners from shifting soil: San Antonio’s shrink-swell clay soils expand and contract with rain and drought cycles, and that movement transfers through the chimney structure. Older masonry chimneys in neighborhoods like Monte Vista and Olmos Park commonly show cracked tiles near the crown, which a camera scan picks up long before a chimney fire does.
- Bird nests and debris in uncapped chimneys: San Antonio’s grackle and starling populations build aggressively inside chimneys that lack proper caps or spark arrestors. A nest on the smoke chamber shelf can restrict draft and send smoke back into the living room, which is exactly what our tech found in that 1940s bungalow off Broadway near Alamo Heights.
- Gas fireplace inserts that haven’t been serviced since installation: We regularly service gas units in Stone Oak and The Dominion that have never been cleaned or had their venting checked. The homeowner assumes gas means “no maintenance,” which is how small problems become carbon monoxide risks.
- Creosote buildup from wet or unseasoned wood: San Antonio’s mild winters mean many homeowners burn whatever firewood is available, often oak or mesquite that hasn’t seasoned fully. Green wood produces more creosote per fire than dry wood, and that accumulates fast inside a clay tile liner that’s already rough from age.

FAQs About Chimney Sweep in San Antonio
Once a year if you burn wood regularly during the November through February season, and every two years if you only light fires occasionally. Creosote builds faster in San Antonio’s dry air than people expect because the temperature swings between cold nights and warm days create condensation cycles inside the flue. If you burn green mesquite or unseasoned oak, sweep annually no matter how little you use the fireplace. Call (830) 251-4560 and we’ll help you figure out a schedule that matches how you actually use your fireplace.
The flat price covers the complete sweep, creosote and soot removal, damper check, chimney cap and spark arrestor inspection, a full camera scan of the flue liner, and a written photo report. You get that price in writing before any work starts, and you pay the same amount when the job is done. No add-ons appear at the door. If the camera shows a problem that needs repair, you’ll get a separate written quote for that work, and you decide whether to move forward or not.
Yes, and we do it on every job. The camera footage and photo report are what make that answer honest. Cracked clay tiles near the crown of a San Antonio chimney on shifting clay soil might be stable enough to monitor for a season, or they might be a fire risk that needs attention before the next burn. We’ll tell you which one applies to your chimney, in plain words, and you’ll have the photos to verify it. Call (830) 251-4560 to schedule a camera scan.
We service both. Gas fireplace cleaning in San Antonio runs $149 – $249 and includes cleaning the glass and burner assembly, checking the pilot and venting, and following the manufacturer’s service schedule. Many gas units in San Antonio homes have never been serviced because homeowners assume gas means no maintenance. The venting still needs checking each year for carbon monoxide safety, even if there’s no creosote involved.
The photos give you evidence instead of a verbal claim. We’re looking for cracked clay tiles, spalling mortar, missing or deteriorated flue tile joints, bushings, bird nests, and creosote buildup that the sweep didn’t fully remove. In San Antonio’s older masonry chimneys on shifting clay soil, cracked tiles are the most common finding, and those cracks are what a Level 2 inspection is designed to catch before a sale or a chimney fire forces the issue. You keep the photo report regardless of whether you schedule any repair.
