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
Chimney repair in San Antonio typically runs $425 – $1,900 for crown work, repointing, or flashing replacement, and most jobs our crews handle on a single visit once we have your written approval on price. San Antonio is our backyard, from the ranch houses off Curley Road to the newer builds along State Road 52, and we know exactly how our clay soil and freeze-thaw winters punish chimneys here. If you want a straight answer, call (830) 251-4560. We’ll give you a flat price in writing before anything goes on the roof.
Why Flint Chimney Sweep Is San Antonio’s Preferred Chimney Repair Company
We’re part of the Garrison Partners family, founded in 2002, and we run every San Antonio job under The Garrison Standard: a written price before work starts, a uniformed and background-checked technician on the dispatch, and a 365-Day Done Right Promise on every repair. Our Chosen Chimney repair crew has worked neighborhoods from the Shady Hills side of San Antonio down toward the Mirada subdivision and out past the I-75 corridor, and we don’t treat your chimney like a learning exercise.
Homeowners in San Antonio tell us the same stories: a crew that no-shows, a price that changes at the door, or a repair recommendation nobody can justify. We answer that with camera evidence. Every inspection includes a photo report you can see with your own eyes. If the liner is fine, we’ll say so. If the crown is cracked, you’ll see the photos before you approve a dime. Our repair team is led by Hank Delano, and every job is backed by a written guarantee for a full year, with a free return visit if a covered repair fails.
Chimney Crown Repair in San Antonio
Chimney Crown Repair in San Antonio is the single most common repair we quote, because our shrink-swell clay soil shifts foundations enough to crack the concrete crown that caps your chimney. The crown is the flat slab at the very top, and its whole job is to keep water out of the brick below. Once it’s cracked, water works into the mortar every time it rains, and a few freeze nights turn hairline cracks into spalling brick within one winter.
How a crown repair runs
We clean the crown surface, fill cracks that are structurally sound, and apply a professional-grade flexible sealant from Gelco when the cracking is minor. If the crown is crumbling or the cracks run through the full thickness, we rebuild the crown with a proper pour and a slight overhang so water drips clear of the brick. Every crown repair in San Antonio carries our full-year guarantee in writing.
What you’ll pay in this market
A standard crown sealing job on a single-flue San Antonio chimney runs $425 – $700. A crown rebuild with form work and new concrete runs $1,100 – $1,900 depending on flue count and roof access. You’ll have the exact number in writing before we move a ladder.
Chimney Repair Companies in San Antonio
Chimney Repair Companies in San Antonio range from national chains that subcontract to whoever’s available, to one-truck operations with no written guarantee to speak of. We don’t subcontract, and we don’t ask you to trust a verbal promise. Flint Chimney Sweep dispatches our own background-checked, uniformed technicians on every job, and the 365-Day Done Right Promise is printed on your estimate.
What separates us from the others
We put the scope, price, and warranty in writing before a single tool comes off the truck. If we find something during the repair that changes the plan, work stops, you see the photos, and you approve the new number in writing. No pressure, no “while we’re up here” surprise.

Trusted Brands We Service in San Antonio
We install and specify chimney materials from brands whose products we can stand behind: HeatShield for resurfacing fire-damaged flue liners, Olympia Chimney for stainless-steel liner systems, and Famco for caps and dampers that fit San Antonio’s standard flue sizes. We keep common replacement parts stocked for fast turnaround on the jobs we quote in Pasco County, so you’re not waiting on a national backorder for a crown sealer or a chimney cap. Every material is specified by what your job actually needs, never by what moves the most margin.
Common Chimney Repair Problems We See in San Antonio Homes
- Cracked crowns from clay soil movement. Our wet springs and dry autumn stretches make the ground under San Antonio slabs and piers swell and shrink. That movement transfers up through brick chimneys and splits the crown along the flue opening.
- First-degree creosote on the first cold snap. Homeowners wait until the first Norther, then burn a cold, damp flue. That first fire glazes a thin, sticky creosote layer onto an already-compromised liner, and that’s when the downdraft smells start.
- Freeze-thaw mortar spalling. We don’t get many hard freezes, but the ones we do get put water into hairline mortar cracks, freeze it, and pop the mortar face off the brick. It looks cosmetic in July. By January, it’s structural.
- Flashing pulled loose from foundation settling. Where the chimney meets the roof line, the metal flashing takes the brunt of any movement. Once it lifts even a quarter inch, every Tampa Bay rain gets underneath and into the smoke chamber.
Pricing for Chimney Repair in San Antonio, FL
You should know the ballpark before you call. Mortar repointing in San Antonio usually runs $14 – $22 per square foot of brick face. Tuckpointing on a standard single-flue chimney runs $600 – $1,200 total. Chimney waterproofing after we repair the crown runs $350 – $550 for a typical two-story home. Flashing repair runs $450 – $850 depending on how much existing flashing is salvageable. A partial chimney rebuild where the top courses of brick have spalled runs $1,800 – $3,200. Full rebuilding from the roofline up starts around $3,500 and scales with height, access, and flue count. Every estimate is free, written, and in your hand before you approve anything. Call (830) 251-4560.

FAQs About Chimney Repair in San Antonio
Yes. The risk isn’t from heavy use; it’s from what happens between fires. San Antonio’s clay soil shifts with rain and drought, cracked crowns let moisture in, and a single fall fire on a damp flue can lay down first-degree creosote in one evening. An annual Level 1 or Level 2 inspection catches the crown and mortar changes while they’re still cheap to fix. If you’re only burning three or four times a year, your liner may not need a brush every visit, but the crown, flashing, and damper still need eyes on them. Call (830) 251-4560 to schedule yours.
First-degree creosote is a thin, sooty, mostly sticky film that forms on the flue walls when smoke from a cool fire condenses before it exits. A standard brush and HEPA vacuum removes it in one pass. Second-degree looks like flaky, hardened tar and may take a rotary clean. Third-degree is a thick, glazed, shiny coating that brushing won’t remove reliably; that’s when we discuss HeatShield resurfacing or a stainless liner rather than forcing a brush through. We show you the camera view so you see exactly which one you have before we quote a dollar amount.
Yes. The price for every chimney sweep, inspection, and repair in San Antonio is written and in your hand before any work begins. If we discover the job is smaller than we quoted, you pay less. If we find something during the repair that expands the scope, we stop, show you the photo evidence, and get your written approval before continuing. The number on your final invoice will be the number you approved. The 365-Day Done Right Promise is included at no extra charge, and it covers the repair for a full year.
If the cracks are purely cosmetic and the crown still sheds water away from the flue, then yes, it can wait a season while you watch it. If moisture is getting into the brick, or if San Antonio gets another freeze event with water sitting in those cracks, the damage will be compounded within months. The only way to know which situation you have is a camera inspection of the crown surface and the smoke chamber below. Our honest recommendation: if water is the cause, address the crown before the wet spring. If it’s just surface wear, we’ll tell you so and you can wait. Call (830) 251-4560 for a photo report.
We can sometimes route a technician to a San Antonio home the same day you call, especially for crown sealing, cap replacement, or repointing work that fits a standard dispatch window. We won’t promise a same-day repair by default, because the urgent issue isn’t the hour, it’s the season. The best time to have your chimney repaired in San Antonio is before the first fall fire, not after a panicked cold weekend. Call (830) 251-4560 and we’ll tell you honestly what our schedule looks like this week.
