South Houston is a small city between Houston and Pasadena, and mold remediation here mostly follows roof leaks, plumbing failures, AC condensation and storm water rather than one local cause. Texas requires a mold assessment consultant and a separate remediation company for each project. Call the number on this page to be connected with a local mold remediation company in South Houston.

South Houston in brief
South Houston, about 16 miles from downtown Houston, was incorporated in 1913 and borders both Houston and Pasadena along roads like Spencer Highway, Allen Genoa Road and South Shaver Street. Manufacturers moved in after the Ship Channel was built, and a 1915 hurricane wrecked many local industries. Homes here face the region's usual moisture: humid summers, months of air conditioning, sudden heavy rain and flat ground that drains slowly. Without a creek or bayou to blame, most South Houston jobs trace back to something inside the house, which is good news: once the leak is found and fixed, remediation tends to hold.
What to do now
- Find and stop the source. Roof, plumbing, water heater, AC drain line or exterior grading.
- Dry within 24 to 48 hours. Fans and a dehumidifier help; EPA suggests indoor humidity under 60 percent.
- Size it up. Under about 10 square feet, a homeowner can usually clean it. Larger areas or hidden growth call for professionals.
- Book the assessment. A mold assessment consultant who holds a TDLR license writes the protocol.
- Book a different remediator. Texas does not allow the assessor's company to do the removal on that job.
- Ask about permits. Check with the City of South Houston whether your drywall or structural repairs need a permit before rebuilding.

Signs and likely causes
| What you see | Likely cause |
|---|---|
| Brown ring spreading on a ceiling | Roof leak or AC pan overflow in the attic |
| Black spots along the bottom of a wall | Water pooling outside or a slab-level plumbing leak |
| Moldy grille on a supply vent | Cold air meeting humid room air |
| Mildew on shoes and clothes in a closet | Stale air and high indoor humidity |
Cost factors
Angi's Houston cost data puts most removal jobs between $863 and $3,329, with a full span of $500 to $5,500. The size of the affected area, how much drywall and insulation must be removed, attic access, containment, and the assessor's separate charges for the protocol and clearance determine where a South Houston job lands. Repairs after remediation are budgeted separately. Harris County Public Health is the county health department for questions about mold and health.
