In Tomball, a mold inspection checks the home for moisture and growth, pins down the cause and documents everything in a written report. Texas treats this as mold assessment requiring a TDLR license, and the assessing company may not also perform the removal on that project.

Tomball overview
Tomball is a small city in northwest Harris County, about 24 miles from downtown Houston, that grew around the railroad and sits on SH 249 and FM 2920. Its water comes from the Spring Creek and Willow Creek watersheds. The Harris County Flood Control District lists Tomball among the communities affected by the 2016 Tax Day flood. During Hurricane Harvey the city saw relatively little damage compared with Houston, but floodwater rose into homes near Spring, Willow, Mill and Walnut creeks, and first responders made about 15 water rescues. The city stresses that FEMA maps are estimates and that homes outside the 100-year floodplain can flood, often from local stormwater ponding. That warning matters for mold: a house that took a few inches of water from a flooded street can hide wet drywall and carpet pad just as surely as one beside a creek.
Do this first
- Track down the moisture: street ponding at doors, roof leaks, plumbing or the AC drain.
- Dry wet materials fast; EPA's guidance is 24 to 48 hours.
- Don't paint, caulk or bleach over visible growth.
- Book a mold assessment and request a written report with photos.
- Before rebuilding, apply for permits through the City of Tomball Building Division's SmartGov portal (281-290-1451).

Signs and their usual causes
| Sign | Usual cause |
|---|---|
| Stained carpet tack strip at an exterior door | Stormwater ponding against the threshold |
| Musty AC closet | Clogged condensate drain or wet insulation around the air handler |
| Dark patches on attic decking | Roof leak or poor attic ventilation |
| Mold on drywall behind a refrigerator | Leaking ice-maker line |
Cost factors
Angi's Houston cost data reports an average of $453 for inspection and testing, typically $355 to $563. Home size, attic access, the number of AC systems and lab samples drive the final price. HomeGuide puts most inspections at 2 to 5 hours. If removal is needed, a different company does it under Texas law, and the assessor returns afterward for clearance. Tomball's Code Compliance officers work within the Building Division under the 2021 International Property Maintenance Code, and renters with unrepaired leaks can contact them. Tomball's floodplain administrator can help you read the city's flood maps, and a surveyor can establish your home's elevation.
