Mold & Mildew Cleanup in Missouri City, TX

Why does mildew keep showing up in my Missouri City home?

Missouri City is a suburb of about 74,300 people in eastern Fort Bend County, with part in Harris County, about 15 miles from downtown Houston. Zoned since 1981, it is mostly single-family homes in areas such as Quail Valley, Lake Olympia and Lakes of Brightwater, and Oyster Creek flows south through the city. The weather is the main driver: humid air, a cooling season that lasts most of the year, and heavy rain. In the Memorial Day 2016 Brazos River flood, runoff came within feet of covering Highway 6 and fourteen city streets were impassable. Inside the house, mildew keeps returning when:

• A bath fan is too weak or turned off right after a shower
• The AC cools the house without pulling enough moisture from the air
• Vent covers sweat where cold air meets humid room air
• A slow leak under a sink or behind a tub keeps a wall damp
• Stormwater sits against the slab on slow-draining clay

Can I clean it myself, and how?

Usually. Texas lets homeowners clean mold in their own homes without a license, and EPA says areas under about 10 square feet are typically manageable. Scrub hard surfaces with detergent and water, dry them completely, and wear gloves, eye protection and an N-95. Don't paint or caulk over mildew, and discard porous items such as old bath mats that have grown mold. Then deal with the moisture, aiming for indoor humidity below 60 percent, ideally 30 to 50 percent.

What does professional cleanup cost, and who does it?

Angi's Houston cost data reports mold removal averaging $2,016, typically $863 to $3,329, and national ranges (HomeGuide, 2026) put a bathroom at $500 to $2,000. On a professional project, Texas law requires two separate companies: a mold assessment consultant who holds a TDLR license writes the protocol and later checks clearance, and a company with a TDLR mold remediation contractor license does the cleanup. After the job you receive a Certificate of Mold Damage Remediation.

A local note

Rebuilding after cleanup goes through Missouri City Development Services, Permits and Inspections. The city's Code Enforcement division enforces property maintenance rules such as keeping exterior walls free of holes and rot. Fort Bend County Health and Human Services does not take mold complaints.
