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 Alamo Heights
Chimney repair in Alamo Heights typically runs $450 – $2,800 depending on whether we’re rebuilding a crown, repointing masonry, or replacing flashing. Most jobs take one day, and every repair carries a written one-year guarantee. If you’ve noticed water stains on the ceiling near your fireplace, crumbling mortar on the exterior chimney stack, or a draft that wasn’t there last winter, call (830) 251-4560 and we’ll walk you through what we’re seeing and what it costs to fix.
Alamo Heights sits on Edwards Limestone, and that fact drives more chimney repairs here than anything fire-related. The soil shifts, the masonry moves with it, and crowns crack before creosote ever becomes the problem. Our crews know the difference because Hank Delano has been running Flint Chimney Sweep under the Garrison Partners umbrella since 2002, and the discipline hasn’t changed: written price before work starts, background-checked techs in uniform, and a live person on the phone around the clock.
Why Flint Chimney Sweep Is Alamo Heights’s Preferred Chimney Repair Company
We built our reputation in Alamo Heights on doing exactly what the estimate says, then showing you the camera footage that proves it. Homeowners off Broadway and Patterson have called us back for years because the invoice matches the approved number and the repair holds. Every job gets documented with photos before and after, so you can see what was actually fixed inside your flue or along your chimney stack.
Hank Delano runs Flint Chimney Sweep under The Garrison Standard, a code every Garrison Partners location follows: the 365-Day Done Right Promise means if a covered repair fails within one full year, we return at no charge and make it right. No argument, no re-quote, no fine print. That’s the difference between a company that sells chimney work and one that stands behind it in writing.
When you call (830) 251-4560, a live person answers. Not a voicemail tree, not a callback form. If you’re in the 78209 ZIP code or over by Cambridge Oval, we’ll get a uniformed, background-checked technician to your door and hand you a written price before a single tool comes off the truck.
Chimney Flashing Repair in Alamo Heights
Chimney flashing repair in Alamo Heights addresses the metal barrier where your chimney meets the roofline, and on older homes here it’s one of the most misdiagnosed problems we see. The flashing takes direct hits from the Texas sun and the soil movement underneath shifts the chimney stack just enough to break the seal. When water finds that gap, it travels inside the chase and shows up as a ceiling stain or peeling paint near the fireplace. On Alamo Heights homes, a flashing repair typically runs $350 – $900 depending on whether we’re patching a section or replacing the full step and counter flashing assembly.
Step Flashing vs. Continuous Flashing
Alamo Heights homes built before 1960 often have step flashing cut into the masonry, which was standard at the time but leaves more failure points than modern continuous flashing. We assess what’s there, show you photos, and tell you plainly whether a patch will hold or whether the full assembly needs replacement. The answer goes in writing before any work begins.
When Flashing Fails on Limestone Sites
On this shallow rocky soil, the chimney and the roofline move at slightly different rates when the ground settles, especially after a wet spring. The first sign is usually a water stain, not a fire hazard. If you’ve spotted one, call us before it becomes a mold problem inside the chimney chase.
Chimney Crown Repair in Alamo Heights
Chimney crown repair in Alamo Heights fixes the concrete cap that sits atop the masonry chimney, and on this limestone substrate it’s our single most common repair call. The crown’s job is to shed water away from the flue and the brick below, but soil movement cracks the crown and lets moisture into the chimney system. Once water gets in, it starts spalling the brick face, rusting the damper, and in worst cases degrading the liner. In Alamo Heights, a crown repair typically runs $600 – $1,400, with a full rebuild on the higher end when the existing cap is beyond salvage.
Spalling Brick Repair
When a crown cracks and lets water in, the first visible casualty is usually the brick face. Freeze-thaw cycles here in south Texas are less severe than up north, but the summer heat bakes moisture into the masonry and the bricks start popping face fragments. We cut out the failed units, rebuild with matching brick and proper mortar, and the repair goes into the written guarantee.
Mortar Repointing and Tuckpointing
Once the crown is sound, the next step on a lot of Alamo Heights homes is pulling out the failed mortar joints and packing new mortar. We do this by hand because the older lime-based mortars on 1920s to 1950s chimneys don’t bind well with modern Portland cement. The wrong mortar is worse than no mortar, and we’re not willing to do it wrong.
Trusted Brands We Service in Alamo Heights
When we replace a liner or rebuild a crown, we’re not shopping by price. We use DuraFlex stainless liners and Olympia Chimney crowns and caps because they hold up to the specific conditions here: shifting soil, humid springs, and the occasional Texas gullywasher. Our techs stock the parts Alamo Heights homes need most, which means fewer second trips and faster turnaround when you call (830) 251-4560. We’ll tell you the exact brand and product going into your chimney before any work starts, because you should be able to verify the material quality independently.
Common Chimney Repair Problems We See in Alamo Heights Homes
- Cracked crowns from limestone soil movement. The shallow Edwards Limestone substrate means the ground under your chimney can shift just enough to crack the concrete cap, and that crack is where water gets in. We see this on Alamo Heights chimneys long before any creosote build-up becomes a threat.
- Shifted flashing after wet springs. When the soil takes on water and settles unevenly, the flashing seal between chimney and roof is often the first thing to break. On homes near Broadway where the tree canopy holds moisture in the ground, this cycle repeats year after year.
- Unlined or undersized flues in pre-war construction. Original Alamo Heights homes built between the 1920s and 1950s often have masonry chimneys without a properly sized flue liner. The cracking shows up inside the smoke chamber, not at the exterior, which is why a camera inspection matters.
- Moisture and animal intrusion on uncapped flues. Streets like Patterson have dense tree cover, and uncapped chimneys collect leaves, humidity, and nesting animals. The result is a rusted damper and a draft problem that looks like a creosote blockage but is actually moisture-related.

FAQs About Chimney Repair in Alamo Heights
Once a year, before burning season, is the right interval for most Alamo Heights homes. If you burn more than twice a week through the winter, split it into two checks. The inspection catches crown cracks and flashing gaps from soil movement before water works its way into the house. Call (830) 251-4560 and we’ll book the inspection and give you a written price first.
Hairline cracks in the crown can usually wait until spring without getting worse. Water stains on the ceiling, a strong smoky smell after rain, or crumbling brick on the exterior should not wait, because those mean water is already inside the chimney system. We’ll be straight with you on the phone and tell you if it’s a now-job or a season-job.
We show up in the window we gave you, assess the chimney, and run a camera inspection if there’s any question about the flue condition. Then we walk you through the photos, give you a written price, and you decide. No work starts until you approve the number, and the 365-Day Done Right Promise covers every repair for a full year.
Third-degree creosote is the hard, glazed tar that builds up when flue temperatures stay low and moisture is present. A standard brush won’t touch it, and the moisture from Alamo Heights humidity makes it more likely to form. That’s when we use a chemical treatment or a rotary cleaning head, and we’ll show you the before-and-after camera footage so you know it’s actually gone.
No, not usually. Most cracked crowns can be resurfaced or partially rebuilt without touching the rest of the chimney. A full rebuild is only needed when the masonry below the crown has already deteriorated, and we’ll show you the camera evidence before we recommend anything that invasive. The written estimate will state exactly what’s needed and what isn’t. Call (830) 251-4560 for a free estimate and a straight answer.
Contact Flint Chimney Sweep for Chimney Repair in Alamo Heights
If you’ve got a chimney problem in Alamo Heights, call (830) 251-4560 and talk to a live person. We’ll get you scheduled, put the price in writing before any work starts, and the repair is covered by the 365-Day Done Right Promise. On a 1940s bungalow off Broadway near Cambridge Oval, our tech found a spalling crown and a hairline crack running into the flashing after the homeowner noticed a ceiling stain following a spring storm. We rebuilt the crown, reset the flashing, installed a stainless steel cap, and ran a Level 2 camera inspection up the flue. The liner checked out, so the repair stayed exterior and the homeowner avoided a full reline. That’s the way it should work: find the actual problem, fix the actual problem, and prove it with photos.
