Commercial Mold Remediation in Tomball, TX

Tomball in brief

Tomball is a small city in northwest Harris County, about 24 miles from downtown Houston, that grew around the railroad running through downtown after 1906. Businesses line FM 2920 (Main Street), State Highway 249 and the Grand Parkway, and Tomball Regional Medical Center and nearby David Wayne Hooks Memorial Airport anchor the area. Spring Creek and Willow Creek drain the city. The Tax Day flood in April 2016 affected Tomball, and in Hurricane Harvey water rose into homes near Spring, Willow, Mill and Walnut creeks, with about 15 water rescues, though the city saw relatively little damage compared with Houston. The city stresses that buildings outside the mapped 100-year floodplain can still flood, often from local stormwater ponding.

What to do now

1. Stop the leak or ponding water and start drying; EPA's target is 24 to 48 hours.
2. Do not run an air handler that may be contaminated.
3. Estimate the size. Below 25 contiguous square feet, a non-residential owner or tenant and their employees may clean it.
4. At or above that size, bring in a mold assessment consultant to write a protocol, then a separate remediation company.
5. Expect the remediation company to notify TDLR at least five days before a project that size starts.
6. Apply for rebuild permits through the City of Tomball SmartGov portal once remediation is cleared.

What you see and what usually causes it

Cost factors

Area involved, access to ceilings and wall cavities, containment, after-hours work in medical or retail space, and HVAC cleaning all shape the price. Budget for both the consultant and the remediation company. HomeGuide's 2026 national figures list $15 to $30 per square foot. Tomball has its own floodplain administrator, and the city's Code Compliance officers enforce the 2021 International Property Maintenance Code.
