Fast, Reliable Chimney Repair Across Houston
Most chimney repair in Houston runs $350-$2,800 depending on whether we’re patching mortar, replacing a rusted damper assembly, or rebuilding a chase damaged by the 2021 freeze. Our Chimney Repair team completes most jobs in a single visit, and a live person answers our phones 24 hours a day, every day, including holidays. We’ve been driving to homes from The Heights to Clear Lake for over 42 years, and we know the difference between a masonry chimney in a 1930s Montrose bungalow and a prefabricated zero-clearance unit in a 1985 Katy tract house. That distinction matters because the repair is entirely different. Call (877) 516-5603 for a free estimate with upfront pricing.

Our Chimney Repair Services in Houston
Mortar Repointing
Houston’s older masonry chimneys, particularly in neighborhoods like The Heights and Montrose where homes date to the 1920s-1950s, suffer mortar softening from our persistently high humidity. The February 2021 freeze accelerated this damage in chimneys never designed for freeze-thaw cycling. We grind out deteriorated joints to proper depth and repoint with color-matched mortar rated for Gulf Coast conditions. A typical mortar repointing job on a Houston chimney runs $850-$1,800.
Spalling Brick Repair
Spalling, where brick faces flake and crumble, shows up after water penetrates and freezes. In Houston, it’s less about annual freeze cycles and more about the 2021 event catching unprepared masonry combined with decades of humidity-driven saturation. We remove damaged brick, assess the underlying structure, and install matching replacements. For severe spalling on Houston chimneys, expect $1,200-$2,400.
Chimney Waterproofing
With Houston’s relative humidity averaging above 75% year-round, waterproofing isn’t optional for masonry chimneys, it’s preventive maintenance that pays for itself. We apply vapor-permeable sealers that let the chimney breathe while blocking liquid water, critical in a climate where moisture never really dries out. Most Houston waterproofing jobs run $650-$1,400 depending on chimney size and accessibility.
Flashing Repair
Houston’s driving rain, especially during tropical systems and summer thunderstorms, finds every gap at the roof-chimney intersection. We repair or replace step flashing, counter flashing, and cricket diverters using professional-grade materials. Proper flashing repair in Houston typically costs $450-$950.
Chimney Rebuilding & Tuckpointing
When damage exceeds what spot repair can address, we rebuild. In Houston, this often means reconstructing stucco-clad wood chases around prefabricated units where framing has rotted from humidity intrusion, or rebuilding masonry stacks compromised by the 2021 freeze. Full rebuilds range from $3,500-$8,500. Tuckpointing, the cosmetic and functional renewal of mortar joints, runs $1,000-$2,200 for Houston homes.

Trusted Brands We Service in Houston
We work exclusively with professional-grade materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield, no builder-grade substitutes. For Houston’s humidity-battered prefabricated fireboxes, we stock Famco damper assemblies and HeatShield refractory panel repair systems locally, so we’re not waiting on shipping while your fireplace sits unusable. In Katy, we repaired a 1980s prefab firebox where the refractory panels had deteriorated and the damper was rusted shut. Our crew replaced the damper assembly with a new Famco unit and patched the panels using HeatShield. Same-day completion, documented with photos, backed by our 90-Day Done Right Promise.
Common Chimney Repair Problems We See in Houston Homes
- Rusted dampers and firebox components. Houston’s humidity averages above 75% year-round, and that moisture sits inside unused metal fireboxes for months, aggressively corroding damper assemblies, firegrates, and prefabricated metal panels. We replace more rusted dampers in August than most northern markets see all year.
- Cracked clay flue liners from the 2021 freeze. The February 2021 cold snap exposed a regional vulnerability. Masonry chimneys and clay flue liners in homes built without meaningful freeze-thaw cycling in mind sustained cracking that many owners still haven’t addressed. We inspect with Level-2 camera systems and document the damage with photos you can see.
- Animal intrusions and chimney swift nesting. Chimney swifts, small migratory birds federally protected under the Migratory Bird Treaty Act, routinely nest inside uncapped Houston chimneys from roughly late April through October. Once a nest with eggs or chicks is active, any cleaning, capping, or liner work is legally off-limits until the birds depart. We proactively schedule jobs before May or after October.
- Moisture damage to prefabricated chase structures. The overwhelming majority of Houston chimneys are prefabricated zero-clearance metal firebox units set inside wood-framed chases clad in stucco or brick veneer, a product of rapid suburban tract-home construction during the 1970s-1990s oil-boom years. These chases rot from humidity intrusion, requiring inspection of wood framing integrity, not mortar tuckpointing.

FAQs - Chimney Repair in Houston
Houston’s relative humidity, averaging above 75% year-round, aggressively rusts metal dampers, firegrates, and prefabricated firebox components during the long months when your fireplace sits unused. We replace rusted damper assemblies with Famco units and repair deteriorated refractory panels with HeatShield, typically completing the work in a single visit. Call (877) 516-5603 for a free inspection and exact quote.
Stop using the fireplace immediately and call us. You likely have chimney swifts, federally protected migratory birds that nest in Houston chimneys from late April through October. Once eggs or chicks are present, any cleaning, capping, or repair work is legally prohibited until the birds depart on their own. We can inspect, confirm the species, and schedule proper work for November through April. Call (877) 516-5603, we’ll advise you on timing at no charge.
Not necessarily. Many Houston chimneys sustained cracked clay flue liners or spalled brick from that freeze event, but the damage is often localized and repairable with targeted repointing, liner replacement, or partial rebuilding. We perform Level-2 camera inspections to document exactly what failed and provide photos with a plain-English verdict. Full rebuilds are only recommended when structural integrity is compromised. Call (877) 516-5603 for a free assessment, estimates are free and carry no obligation.
Yes, and it’s one of our most common Houston repairs. Prefabricated zero-clearance fireboxes dominate the city’s post-1970s housing stock in areas like Katy, Sugar Land, and Clear Lake, and their metal dampers rust shut from humidity exposure. We replace the assembly with a new Famco unit and inspect surrounding refractory panels for heat damage, completing most jobs in one visit. Typical cost in Houston runs $650-$1,350. Call (877) 516-5603 for an exact quote, estimates are free.
Yes, particularly for masonry chimneys in older Houston neighborhoods like Montrose and The Heights. Our humidity never gives brick and mortar a true drying season, so water penetration causes efflorescence, mortar softening, and accelerated freeze damage when cold snaps do arrive. Vapor-permeable waterproofing blocks liquid water while letting the chimney breathe, a square deal that prevents costlier repairs later. Most Houston waterproofing jobs run $650-$1,400. Call (877) 516-5603 for a free evaluation.
