Tomball is a small city in northwest Harris County in the Spring Creek and Willow Creek watersheds, and the city itself warns that homes outside the mapped floodplain can still flood from local ponding. That water, plus humid summers and attic AC systems, is what feeds mold here. Call the number on this page to be connected with a local mold remediation company in Tomball.

Mold services in Tomball
Tomball grew around the railroad, which arrived in 1906 and ran right through downtown, and it takes its name from Thomas Henry Ball. The city of about 12,300 people (2020 Census) sits on SH 249 and FM 2920, which is Main Street, about 24 miles in a straight line northwest of central Houston, with the Grand Parkway passing nearby.
Local conditions
The Harris County Flood Control District lists Tomball among the communities affected in the April 2016 Tax Day flood. Harvey did less damage here than in Houston, but floodwater still rose into homes near Spring, Willow, Mill and Walnut creeks, and first responders made about 15 water rescues. The City of Tomball has its own floodplain administrator and posts FEMA maps, a revised city floodplain map and flood studies for Spring Creek and Willow Creek. It stresses that FEMA maps are estimates and that homes outside the mapped 100-year floodplain can still flood, often from local stormwater ponding. A surveyor can establish a home's elevation relative to the base flood elevation, and the city urges residents to carry NFIP flood insurance.
Inside the house, the drivers are the same as across the region: long, humid summers; air handlers and ducts in hot attics; condensate lines that clog; roofs that take heavy tropical rain.
Inspection or testing?
| Inspection (assessment) | Testing (sampling) | |
|---|---|---|
| What it is | A visual and moisture check that finds mold and its source | Air or surface samples sent to a lab |
| When it helps | Almost always the first step | When mold is suspected but hidden, or to confirm cleanup |
| EPA view | Fix moisture and remove growth | Usually unnecessary when mold is visible; no federal limits exist |
Tomball offices
The Building Division of Community Development issues building permits through the SmartGov portal ((281) 290-1451, building@tomballtx.gov). Mold removal itself isn't permitted work, but repairs afterward may be, and floodplain properties may have added rules. The Building Division's Code Compliance Officers enforce the city's adopted 2021 International Property Maintenance Code, which is where renters can turn about unaddressed leaks after giving the landlord written notice. Texas Property Code 92.052 sets the landlord's repair duty for conditions affecting health or safety, when rent is current (general information, not legal advice). Harris County Public Health is the county health department.
Texas licensing and the call
TDLR licenses mold assessors and remediators, and the two must be different companies on the same project. Expect a written protocol, a clearance check and a Certificate of Mold Damage Remediation. When you call, you'll be connected with an independent company serving Tomball.
