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 Repair Across San Antonio
San Antonio Chimney Repair typically runs $350 to $1,800 depending on the specific fix, and most masonry repairs get scheduled within three to five business days. That’s not a vague estimate, it’s the range we quote over the phone before anyone books a truck. If you live in Alamo Heights, Stone Oak, or Monte Vista and you’re seeing cracked mortar, a rust-streaked firebox, or water stains near the chimney chase, call (830) 251-4560 and we’ll give you a written price before we even schedule the visit.
We know San Antonio chimneys the way a local should. Those 1940s bungalows off Fredericksburg Road, the 1980s production builds in Westover Hills, the big custom jobs up in Sonterra, each one ages differently. And San Antonio’s caliche-clay soil does something specific to masonry that you won’t see on the Gulf Coast or up in the Hill Country. More on that below.
Why Flint Chimney Sweep Is San Antonio’s Preferred Chimney Repair Company
We run on a simple process. You call (830) 251-4560, a live person answers, we schedule a time and send a background-checked, uniformed technician. That tech arrives in the window we gave you, performs the inspection or repair, and hands you a written report with photos before any work moves forward. Every repair carries a 365-Day Done Right Promise, backed in writing, valid for one full year from the service date. If a covered repair fails inside that year, we return at no charge. No argument, no re-billing. That’s the Garrison Standard, and it applies on every job we do in San Antonio.
We run the same code every Garrison Partners location follows. The Garrison Code means a written price before work begins, every time. The number you approve is the number on the invoice. Our San Antonio customers call us back for that reason more than any other. When a homeowner in Shavano Park needs a crown rebuilt or a flue relined, they don’t want a handshake promise. They want it on paper.
Since 2002, as part of the Garrison Partners family of independently owned chimney service companies, we’ve built a reputation in San Antonio on showing up when we say we will and standing behind repairs with a guarantee you can hold us to. Hank Delano leads our team, and the standard he set applies the same on a small tuckpointing job in Terrell Heights as it does on a full chimney rebuild in Olmos Park.
Chimney Repair Companies in San Antonio
Chimney Repair Companies in San Antonio generally fall into two camps: sweep-only outfits that may not carry masonry expertise, and full-service crews like ours that handle everything from mortar repointing to full rebuilds. What separates us is the written guarantee and the camera proof. When our team works on your chimney, we document every stage and hand you the photos.
Here’s what a typical Chimney Repair call involves in San Antonio. First, the inspection. We run a camera up the flue and through the smoke chamber, because what you can see from the firebox floor is maybe 10 percent of the story. Then we give you a written quote. Then we do the work, photograph it, and leave you with a report.
Flashing Repair and Leak Stops
San Antonio’s spring and fall storms push wind-driven rain against chimney flashing at an angle that tests every seam. We routinely replace rusted or lifted flashing with new step and counter flashing, sealed properly at the roofline. A flashing repair on a standard one-story San Antonio home typically runs $450 to $900.
Crown Rebuilds and Water Management
The crown is the concrete cap on top of the chimney, and it’s the first thing that fails on older San Antonio homes. When it cracks, water gets into the smoke chamber and eats away at the mortar and damper hardware. We rebuild crowns with a proper overhang and drip edge, and the typical cost in San Antonio runs $800 to $1,600.
Chimney Masonry Repair in San Antonio
Chimney Masonry Repair in San Antonio covers the brick-and-mortar structure itself: repointing, spalling brick replacement, tuckpointing, and partial or full rebuilds. This is where the local soil story matters most. San Antonio sits on caliche and clay that expand and contract hard through our wet-dry cycles. That movement transfers up through the chimney stack, and the mortar joints, being the most brittle part of the structure, start cracking well before the brick itself fails.
What that means in practice: a chimney in San Antonio that’s still structurally sound at the roofline can develop crown cracks and upper-course mortar failure years before a similarly built chimney in, say, Corpus Christi where the soil moves less. We factor that into every inspection.
Mortar Repointing and Tuckpointing
Repointing means scraping out the failing mortar and replacing it with fresh material matched to the original. On an average San Antonio chimney, full repointing of the exposed stack above the roofline runs $900 to $2,200 depending on height, access, and how much mortar needs removal. Tuckpointing, which is the finer work of restoring a specific joint profile, lands in a similar range.
Spalling Brick Repair and Partial Rebuilds
Spalling, where the brick face pops off due to trapped moisture and freeze-thaw stress, is common on San Antonio homes built before 1970. We cut out damaged brick, replace it with matched salvaged or new material, and repoint the surrounding joints. A partial rebuild of a badly spalled chimney above the roofline generally falls between $1,500 and $3,500, full rebuilds run higher and get quoted after a structural assessment.
Here’s the Chimney Repair in San Antonio work we know best: older masonry chimneys on pier-and-beam homes in Jefferson, Beacon Hill, and Alta Vista, where 60 to 80 years of soil movement and deferred maintenance have left their mark. We don’t recommend repairs you don’t need. We show you the photos and let the chimney make the case. If it can safely wait, we tell you that in plain words and note it in the report.
Trusted Brands We Service in San Antonio
We stock and install professional-grade chimney products, and we specify them by job, not by margin. For flue relining, we work with HeatShield and Gold-labeled DuraFlex liners, both proven systems in San Antonio’s fire codes and climate. For crown and masonry sealing, we use Gelco repair in San Antonio with their crown coat and waterproofing products, brushed on and tooled for the wet-dry cycles our caliche soil creates. For dampers, caps, and chase covers, we carry Olympia Chimney and Famco hardware at our San Antonio shop, which means most repair parts don’t require a second visit or a week of waiting. We keep common sizes in stock so a crown rebuild or flashing replacement on a standard San Antonio chimney can usually be completed in a single appointment.
Common Chimney Repair Problems We See in San Antonio Homes
- Cracked crowns from soil movement. San Antonio’s caliche-clay ground expands in the wet months and contracts hard in the dry ones. That rhythmic flex, over decades, works cracks into chimney crowns and upper mortar courses, letting rain into the smoke chamber. We see it constantly on pre-1980 chimneys across the city.
- Rust-streaked fireboxes after rain. When a cracked crown or worn flashing lets water run down the flue, the first visible sign is usually a rust stain on the back wall of the firebox. By the time you see it, water has already been moving through the smoke chamber. A camera inspection tells us how deep the damage runs.
- Glazed creosote on rarely used chimneys. San Antonio winters are mild, so a lot of homeowners burn only on the handful of genuinely cold nights in December and January. That infrequent burning builds a first-degree creosote film that sits and seasons, and over several years, it hardens into second-degree buildup a standard brush can’t clear. The fix is a chemical treatment or rotary removal, then a proper sweep.
- Hidden mortar damage behind soot. The smoke chamber gets coated in a fine layer of soot on every fire. That layer hides cracked and spalled mortar joints until a Level 2 camera inspection lights them up. By the time a homeowner sees loose mortar falling into the firebox, the flue liner has usually taken damage too.
Pricing for Chimney Repair in San Antonio, TX
Here’s the straight answer, with real numbers for San Antonio’s market. A standard flashing repair runs $450 to $900. A crown rebuild sits between $800 and $1,600. Full mortar repointing of the exposed stack falls at $900 to $2,200. Spalling brick repair and partial rebuilds range from $1,500 to $3,500. A full chimney rebuild is quoted after we assess the structure, and we won’t give you a blind number on that until we’ve put a camera in the flue and looked at the foundation.
What moves the price: chimney height and roof access, the condition of the surrounding brick, and whether the damage runs into the smoke chamber or stops at the crown. What doesn’t move it: the price itself. We give you a written quote before any work begins, and that’s the number you pay. Call (830) 251-4560 for a free estimate.

FAQs About Chimney Repair in San Antonio
No. If you burn fewer than a dozen fires a year and the chimney has no known leaks, a visual inspection every other year and a professional sweep every 2 to 3 years is generally enough for San Antonio’s climate. What we do recommend every year is a quick check of the crown and flashing from the ground after the first big spring storm, because our wet-dry cycles are harder on masonry than the burn rate is on the liner. Call (830) 251-4560 and we’ll tell you honestly whether an inspection makes sense for your situation.
You’ll know from the report. A sweep handles what’s on the inside of the flue, the creosote and soot buildup. A repair handles the structure: the crown, the flashing, the mortar joints, the liner, the firebox. If you see rust streaks, water stains, or loose mortar, that’s a repair. If the fireplace just smokes a little or hasn’t been cleaned in years, that’s a sweep. We won’t sell you a repair when a sweep is what’s needed, and we won’t sweep over a repair and call it good. The camera tells us, and the photos tell you.
A Level 2 inspection, the one with the camera, is warranted when a home changes hands, when you’ve had a chimney fire even a small one, when there’s visible water entry, or after any major weather event like a hailstorm that battered the roof and chimney. For a San Antonio homeowner in an older pier-and-beam home who’s never had a Chimney Inspection in San Antonio, a one-time Level 2 is a smart baseline. After that, a Level 1 visual is usually fine year to year, unless something changes.
Third-degree creosote is hardened, tar-like buildup that has baked onto the flue liner from repeated high-heat fires or years of low-temperature smoldering. A standard wire brush slides over it. Rotary removal with a chain whip or a chemical treatment like a creosote conditioner is required, and in some cases, the liner itself has already cracked under the heat. If a San Antonio chimney has third-degree creosote, we’ll tell you what removal costs and whether the liner is still safe to use. Call (830) 251-4560 for an exact quote.
Usually not, and we won’t fake it. Some small jobs, like a simple flashing seal or a cap reset, can be done the same visit if we have the parts on the truck and the roof is safe to access. Most masonry repairs need a dedicated appointment, because the work involves staging, mortar mixing, and proper cure time. We’ll give you a written price at inspection and schedule the repair with a firm window. No same-day promises, because that’s how rushed work happens. We don’t do rushed.
If you’re seeing water stains, rust streaks, loose mortar, or a chimney that’s leaning even a fraction, call (830) 251-4560. We’ll send a background-checked, uniformed technician who documents everything with photos, gives you a written price before any work begins, and backs the repair with our 365-Day Done Right Promise. That’s how Chimney Repair should work in San Antonio.
