Fast, Reliable Chimney Repair Across San Antonio
Chimney repair in San Antonio typically costs between $350 and $2,800 depending on the scope, with most standard mortar repointing and flashing jobs falling in the $650-$1,400 range. Our technicians complete most repairs in a single visit, and we answer the phone with a live person 24 hours a day, every day, at (844) 803-1545.
We’ve been driving to San Antonio from our shop for over 42 years, and we know the difference between a chimney in Monte Vista that needs a quick flashing tune-up and a crumbling 1920s stack in Dignowity Hill that hasn’t been opened in a decade. The limestone construction, the sudden blue northers, the humid summers that never quite dry the masonry out - this is not generic chimney work. San Antonio’s chimneys fail in specific ways, and we repair them with materials and methods built for exactly what this climate and housing stock deliver.
Why Hearthstone Chimney Co. Is San Antonio’s Preferred Chimney Repair Company
Our reputation in San Antonio was built one repair at a time, mostly by homeowners who called us after a bad experience with someone else. They stay because we document every inspection with photos they can see, explain the verdict in plain English, and put our Chimney Repair guarantee in writing with no arguing. The 90-Day Done Right Promise means if it’s not right, we come back. No paperwork to dig up, no runaround.
San Antonio customers tell us the same thing repeatedly: they called because a live person answered at 7 p.m. on a Saturday, or because our technician showed up in a marked truck, in uniform, and actually looked at the chimney instead of pitching a full rebuild from the driveway. Most of our San Antonio jobs are completed in a single visit. We give upfront pricing before any work starts, so the number on the estimate is the number on the invoice.
Russell Haines has led this company since its founding in 1984, and that continuity matters when you’re inviting someone onto your roof. We’re not a franchise rotating through crews. We’re the same shop, the same standards, the same phone number for over four decades. When we say we’ll be there when we say, we mean it. A company that plans to be in town in thirty more years acts accordingly.
Our Chimney Repair Services in San Antonio
Mortar Repointing
The soft lime mortar used in San Antonio’s pre-1950s chimneys - especially in the King William Historic District and Lavaca - deteriorates faster than modern Portland cement in our humidity cycles. We grind out the failed joints to proper depth and repoint with mortar matched to the original composition and color, not whatever’s cheapest in the truck. A typical mortar repointing job on a San Antonio chimney runs $850-$1,600 for partial work, $1,800-$2,800 for full stack restoration.
Spalling Brick Repair
San Antonio’s local limestone and porous soft brick absorb moisture through our long humid summers, then spall and flake when a sudden January cold front drops temperatures forty degrees overnight. We’ve replaced spalled courses on chimneys in the 78210 corridor where the brick face had literally peeled away from freeze-thaw cycling that never even involved a fire. We source matching brick when possible, or use compatible replacement units rated for our climate, with repairs typically ranging $650-$1,500 depending on height and accessibility.
Chimney Waterproofing
A chimney in San Antonio that sits unused for ten months a year never gets the heat-drying cycle that helps evaporate absorbed moisture. We apply vapor-permeable waterproofing agents - never film-forming sealers that trap moisture inside - specifically formulated for porous limestone and soft brick. This is critical work in neighborhoods like Westside and Dignowity Hill where original masonry has no Chimney Liner & Rebuild - San Antonio protection. Waterproofing a standard San Antonio chimney runs $400-$750, with larger or multi-flue stacks up to $950.
Flashing Repair
The metal junction where your chimney meets the roof takes abuse from San Antonio’s intense UV exposure and sudden wind-driven rain. We see lifted, corroded, or improperly step-flashed installations constantly, especially on the older homes near Broadway and in Alamo Heights where previous repairs used caulk as a substitute for proper metalwork. Our flashing repairs use custom-fabricated galvanized or copper components, with typical San Antonio jobs running $450-$950 for standard repair, $1,100-$1,800 for full counter-flashing replacement on steep or tile roofs.

Trusted Brands We Service in San Antonio
We stock professional-grade materials from HeatShield, Olympia Chimney, and Famco - brands we specify because they hold up in our climate, not because they’re easy to order. HeatShield’s cerfractory resurfacing system handles the thermal shock of San Antonio’s rare but intense firing cycles. Olympia Chimney’s stainless liners resist the acidic condensation that forms in cold, damp flues. Famco caps and dampers keep out the wildlife that colonizes idle chimneys from March through October. We don’t substitute builder-grade parts to hit a price point. The job is done right, with materials that last.
Common Chimney Repair Problems We See in San Antonio Homes
- Lime mortar turned to dust in historic chimneys. The original mortar in King William and Lavaca homes was never meant to survive 130 years of humidity and neglect. We open the joints and find sand held together by memory, not binder.
- Spalling brick from moisture trapped in porous limestone. San Antonio’s local stone wicks water upward from the roofline, then the face pops off in sheets when temperatures crash. It looks like fire damage but it’s weather damage.
- Failed or missing flashing after decades of UV and wind. The 78211 and 78213 ZIPs see a lot of DIY flashing repairs with roofing cement and hope. We remove it all and install proper step and counter-flashing.
- Chimney Swift nests blocking flues in uncapped masonry. From roughly March through October, federally protected Chimney Swifts roost in older San Antonio stacks. Any cleaning or cap installation requires a nesting check first, or the homeowner faces federal wildlife liability. This is a scheduling reality we handle carefully, not skip.

What moves the number? Height and roof pitch affect labor time. Matching historic brick or specialty mortar adds material cost. Accessibility - chimneys tucked behind additions or over fragile tile - requires scaffolding or specialized setup. We inspect, photograph, and quote before any work begins. The estimate is free, and the price we give is the price you pay.
We also offer $50 off any repair over $250, a free second opinion on any written estimate you’ve already received, and a permanent 5% discount for seniors and veterans. Call (844) 803-1545 to schedule.
