In Katy, mold usually grows where an AC system, plumbing line, roof or heavy rain kept something wet longer than a day or two. Fixing the water source comes first; then damaged material is removed under a written Texas protocol. Call the number on this page to be connected with a local mold remediation company in Katy.

Mold services in Katy
Three counties, one city
The City of Katy sits where Harris, Fort Bend and Waller counties meet, about 19 miles from downtown Houston in a straight line on I-10. It is the center of the larger Greater Katy suburban area, historically a railroad town known for rice farming, with Old Towne Katy, Katy Mills and the Grand Parkway nearby.
The word "Katy" on a mailing address covers far more ground than the city. Inside city limits, the City of Katy Permit and Building Services Division handles building permits, plan review and inspections, and permits are required for all new construction, remodeling and roofing. Unincorporated areas with a Katy address fall under Harris, Fort Bend or Waller County instead. Before rebuilding walls after a mold job, confirm which office covers your address.
Prairie, bayous and slow drainage
Cane Island Creek, a branch of Buffalo Bayou, runs through the area, and Buffalo Bayou's floodplain and tributaries cross the surrounding prairie. Flat former rice land and clay soil drain slowly after heavy tropical rain, so yards and slabs can stay wet. Inside the house, the usual Houston-area sources apply: attic air handlers, clogged drain lines, sweating ducts, and bathrooms that never fully dry. EPA advises drying wet materials within 24 to 48 hours and not running an HVAC system you suspect is contaminated.
Renters and code enforcement
Within city limits, the City of Katy Code Enforcement Division handles nuisance, zoning and property maintenance issues, including building maintenance, through its complaint form. Construction or remodeling without a permit is reported to the Permits Department. Statewide, Texas Property Code 92.052 requires landlords to make a diligent effort to repair conditions that materially affect a tenant's health or safety after notice. This is general information, not legal advice; TexasLawHelp has more.
Health department depends on county
On the Fort Bend side, Fort Bend County Health & Human Services is the county health department, and its Environmental Health division lists mold complaints among services it does not provide. On the Harris or Waller side, check with that county's health department. EPA notes mold can irritate eyes, skin, nose, throat and lungs; take symptoms to a health professional.
Texas licensing in short
Expect two companies: a TDLR mold assessment consultant who writes the protocol and later confirms clearance, and a separate remediation company that does the removal. At the end you receive a Certificate of Mold Damage Remediation. When you call, you will be connected with an independent local company serving Katy.
