Why Hearthstone Chimney Co. of Houston Is Humble’s Preferred Chimney Repair Company
We’ve worked on chimneys in Humble for over 42 years. That means we’ve repointed mortar on 1960s ranch homes near Charles Bender High School, waterproofed brick facades in the newer 77346 subdivisions, and replaced flue liners in Atascocita homes that sat under six feet of water during Hurricane Harvey. Dale Hutchins built this company on the principle that a craftsman explains what’s wrong in plain English, fixes it with materials that last, and stands behind the result without making the homeowner chase him down.
Our Chimney Repair in Humble customers get the same treatment as our Houston clients: a Level-2 camera inspection with photos you can see, a written verdict you can understand, and no-hassle upfront pricing. The number on the estimate is the number on the invoice. Most jobs finish in one visit. And if something isn’t right, our 90-Day Done Right Promise means we come back - in writing, no arguing.

Our Chimney Repair Services in Humble
Mortar Repointing
The older brick homes near historic Humble - the 1960s and 1970s ranches along Main Street and in the 77338 core - were built with mortar formulations that simply weren’t designed for decades of Gulf Coast humidity. We’ve ground out and repointed hundreds of these joints. The work runs $18-$32 per square foot in Humble, depending on access and how far the deterioration has spread. We match the new mortar to the existing compressive strength so the repair bonds properly and doesn’t accelerate erosion of the original brick. Done right, repointing stops water intrusion and buys another 25-30 years of service.
Spalling Brick Repair
Spalling in Humble is almost never freeze-thaw damage. Our winters are too mild. Instead, it’s moisture cycling - brick faces flake and pop because Gulf Coast humidity penetrates the masonry, then the summer sun drives it back out with pressure. We see this especially on south- and west-facing chimney stacks in Atascocita and the Timberwood subdivisions. Minor spall repair with proper sealing runs $350-$800. If the brick is too far gone, we source matching replacement units and rebuild the affected courses. Either way, we finish with a breathable waterproofing treatment that lets vapor escape without letting liquid water in.
Chimney Waterproofing
In Humble, a chimney can sit completely unused for ten months and still suffer catastrophic water damage. That’s not theory. After Harvey, we found chimneys in 77338 and 77346 with water-saturated mortar and cracked clay flue tiles concealed behind freshly renovated drywall - damage that insurance-driven rebuilds had simply skipped over. Our waterproofing service addresses this directly: we apply professional-grade siloxane-based sealants from trusted manufacturers, repair or replace deteriorated crowns, and ensure your flashing is intact. Full waterproofing with crown repair typically runs $1,200-$2,400 in Humble. For homes with any Harvey history, we strongly recommend starting with a camera inspection before water stains appear on interior walls.
Flashing Repair
Flashing failures are among the most common calls we get from Humble homeowners, and they’re often misdiagnosed as roof leaks. The constant expansion and contraction of our extreme heat cycles - 95 degrees in August, then a February cold front - separates step flashing from masonry faster here than in milder climates. We repair or replace flashing with galvanized or stainless-steel components, sealed with high-temperature urethane. Typical flashing repair in Humble costs $450-$950. We also inspect the surrounding roofline and cricket structure while we’re up there, because a chimney leak rarely travels straight down.
Chimney Rebuilding & Tuckpointing
When deterioration has compromised structural integrity, we rebuild. In Humble, this most often follows Harvey-era moisture damage that went undetected for years, or decades of humidity erosion in pre-1980s construction. Our Chimney Repair team rebuilds with matching brick, proper mortar, and structural reinforcement where needed. Partial rebuilds start around $3,500; full chimney rebuilds can reach $8,000-$12,000 depending on height and access. Every rebuild includes a new cap, proper flashing integration, and documentation photos.

Trusted Brands We Service in Humble

Olympia Chimney components round out our cap and damper installations. We stock common parts for Humble-area homes so we’re not ordering and making you wait. When our technician arrives, the truck carries what most jobs need.
Common Chimney Repair Problems We See in Humble Homes
- Harvey-concealed moisture damage. In the 77338 and 77346 ZIP codes, fast-tracked post-2017 rebuilds often skipped chimney inspections. Water-saturated mortar and cracked flue tiles hid behind new drywall. We find this with our camera system - damage the homeowner never suspected.
- Chimney swift colonization. Federally protected chimney swifts nest in uncapped chimneys on wooded Atascocita lots near Lake Houston from April through October. Once they’re in, the Migratory Bird Treaty Act prohibits any disturbance. Late-winter cap installation is the only prevention.
- Humidity-driven mortar erosion. Decades of Gulf Coast moisture cycling grind away mortar joints in 1960s-1970s brick homes near historic Humble, even when the fireplace hasn’t seen a log in years. The chimney deteriorates as a structural element, not just a fire feature.
- Flashing separation from thermal cycling. Humble’s extreme heat variation - summer highs near 100, winter lows in the 30s - causes metal flashing to work loose from brick courses. Water follows the gap into wall cavities, showing up as stains on ceilings far from the chimney.

FAQs - Chimney Repair in Humble
Post-Harvey rebuilds in 77338 and 77346 frequently skipped formal chimney inspections, leaving water-saturated mortar and cracked clay flue tiles concealed behind renovated interiors. That hidden moisture continues degrading the structure, and we’ve found flue tile collapse risks in homes that looked fully restored. If your home flooded in 2017 and the chimney was never camera-inspected, call (877) 516-5603 for a free Level-2 inspection - estimates are free, and the photos will show you exactly what you’re dealing with.
Yes. Chimney swifts are federally protected, and once they establish a nesting colony in your uncapped chimney between April and October, the Migratory Bird Treaty Act prohibits any chimney work until they depart in late fall. The only prevention is a properly installed cap before March. We install stainless-steel caps with appropriate mesh spacing that blocks swifts while maintaining proper draft. Call (877) 516-5603 in late winter - waiting until you hear chirping means waiting until November.
Humble’s Gulf Coast humid subtropical climate means your chimney sits idle in extreme heat and humidity for 9-10 months annually. That constant moisture penetration into dormant masonry produces efflorescence, erodes mortar joints, cracks crowns, and separates liner joints - all without a single fire being lit. Freeze-thaw spalling, common in northern climates, is essentially nonexistent here. The damage is slower but relentless, and it’s why we emphasize waterproofing and camera inspection even for homeowners who never use their fireplaces.
Yes - in Humble, minimal fire use is irrelevant to the most common failure modes. Humidity, Harvey-era concealed damage, and thermal cycling attack your chimney as a structural building component, not just a fire feature. We’ve repaired chimneys in Humble that hadn’t burned wood in fifteen years but had mortar erosion severe enough to threaten wall stability. A Level-2 camera inspection every 2-3 years catches what you can’t see from the ground. The $89 Seasonal Tune-Up makes that inspection affordable.
We specify DuraFlex stainless-steel liners for relining work, HeatShield and Gelco for crown repair and resurfacing, and Olympia Chimney for caps and dampers. These are professional-grade materials, not builder-grade substitutes, chosen specifically for their performance in Gulf Coast humidity and UV exposure. We do not use generic or unbranded components. Call (877) 516-5603 if you’d like to discuss material specifications for your specific repair.
