High year-round humidity means wet materials grow mold quickly, and sweating AC ducts cause mold even without leaks. From June through November, tropical systems bring wind-driven rain, roof damage and power outages that leave homes without AC to control humidity.
Three-story townhomes put laundry and bathrooms above living space, so a single leak can run down through two floors. Older homes in the Heights are often pier-and-beam, where water collects in the crawlspace. Slab ranches near the bayous have the highest flood exposure.
Licensing in Texas: Texas doesn't license general contractors statewide, but it licenses mold assessors and mold remediation contractors through the Texas Department of Licensing and Regulation (TDLR) for projects of 25 contiguous square feet or more.

Other risks in Houston
Bayou and street flooding
Brays, White Oak, Buffalo and Greens Bayous overflow in major storms, and flat streets flood in heavy rain even outside mapped floodplains. Hurricane Harvey in 2017 flooded neighborhoods across the city.
Subsidence and old sewer lines
Decades of groundwater pumping caused subsidence across the Houston area. Combined with shifting clay, that movement cracks older cast-iron and clay sewer lines under slab homes, which leads to backups and slow under-slab leaks.
Signs you need mold removal
- Visible spots or fuzzy growth on walls, ceilings or wood
- A musty, earthy smell, especially in closets, basements or crawlspaces
- Recent water damage that wasn't fully dried
How the work is done
Inspect and find the moisture, then Contain the area, then Remove and clean, then Dry and fix the source, then Verify. See the full mold removal process.
What affects the cost
Prices depend on the job, so restoration companies in Houston quote after an assessment. The main drivers are how much area is affected, how long it stayed wet, and what has to be removed or rebuilt. See the full list of mold removal cost factors.
Mold Removal questions
Do I need a permit to repair water damage in Houston?
Cleanup and drying don't. Rebuild work involving plumbing, electrical or structure requires a City of Houston permit, and substantially damaged homes in the floodplain may face elevation requirements.
How fast does mold grow after a leak in Houston?
In Houston's humidity, mold can begin growing on wet drywall and wood within 24–48 hours, which is why drying should start the same day if possible.
Is bleach enough to kill mold?
Not on porous materials like drywall and wood. Bleach mostly lightens the surface. Porous materials with growth are usually removed, and the moisture source has to be fixed.
Do I need mold testing?
Not always. If mold is visible, the priority is removing it and fixing the moisture. Testing helps when you smell mold but can't find it, or when clearance is required.
