When water gets into a Tomball home from Spring Creek, Willow Creek or local ponding and the house stays wet, mold removal means opening and removing the soaked materials and cleaning the framing under a written Texas protocol. A consultant plans it, and a separate company does the removal. Call the number on this page to be connected with a local mold remediation company in Tomball.
Tomball and its creeks
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. It lies in the Spring Creek and Willow Creek watersheds, and the Harris County Flood Control District listed it among the communities affected in the 2016 Tax Day Flood. Tomball saw relatively little damage in Hurricane Harvey compared with Houston, but water still rose into homes near Spring, Willow, Mill and Walnut creeks, and first responders made about 15 water rescues. The city's floodplain administrator stresses that FEMA maps are estimates and that homes outside the 100-year floodplain can flood, often from local stormwater ponding.
Steps to take
- Wait until it is safe, then stop the water and start drying.
- Record the damage with photos and note how high the water reached.
- Keep children and anyone with asthma or a weakened immune system away from the cleanup, as EPA advises.
- Keep the air conditioning off if the air handler or ducts took water.
- Book a mold assessment consultant to write the protocol.
- Hire a different company for the removal and check both on TDLR's license search.
- Apply for any rebuild permit through the City of Tomball's SmartGov portal before replacing walls.

Cost factors
Angi's Houston cost data reports typical mold removal at $863 to $3,329, averaging $2,016. National ranges (HomeGuide, 2026) list $6,000 to $15,000 for 300 to 1,000 square feet. In Tomball, the drivers are the wet area, how long it stayed wet, cabinetry and flooring, containment, and paying both the assessor and the remediator. The city urges residents to carry NFIP flood insurance, and a surveyor can show where a home sits relative to the base flood elevation, which helps when planning the rebuild.
