Mold Removal & Remediation in Missouri City, TX

What causes mold in Missouri City homes?

Missouri City is a bedroom suburb about 15 miles from downtown Houston, mostly in Fort Bend County with a portion in Harris County. Zoned since 1981, it is mostly single-family homes, with master-planned areas such as Quail Valley, Lake Olympia and Lakes of Brightwater. Oyster Creek flows south through the city. In the Memorial Day 2016 Brazos River flood, runoff came within feet of covering Highway 6, fourteen city streets were impassable, and officers went door to door in neighborhoods of concern. Most mold calls, though, come from everyday moisture: attic air handlers that overflow, roof leaks, plumbing behind walls, and humid air meeting cold ducts.

How does a remediation job work in Texas?

A mold assessment consultant who holds a TDLR license inspects and writes a protocol, which you receive at least one calendar day before work. A separate company holding a TDLR mold remediation contractor license writes a work plan, sets up containment, removes damaged materials and cleans what stays. Texas law does not allow one company to do both the assessment and the remediation on the same project. Afterward the consultant performs a post-remediation assessment. Within 10 days after the job you receive before-and-after photos and a Certificate of Mold Damage Remediation.

Who do I contact locally?

For permits on repairs after remediation, contact the City of Missouri City Development Services Permits and Inspections division. The city's Code Enforcement division enforces property maintenance rules, such as keeping exterior walls free of holes and rot, which matters when siding damage lets rain in. Fort Bend County Health and Human Services lists mold complaints among the services it does not provide, so mold questions go to TDLR.

A note on cost

Angi's Houston cost data reports typical removal at $863 to $3,329. Expect a second invoice from the assessor for the protocol and clearance visit, and ask each company to put its scope in writing. A closet-sized job lands near the low end; growth that runs through a wall cavity or into the HVAC system pushes the price up. HomeGuide's 2026 national range for HVAC systems or ducts is $2,000 to $10,000.
