In La Porte, post-flood mold removal starts once the water source is stopped and drying has begun, and it focuses on the drywall, insulation and flooring that stayed wet. A mold assessment consultant writes the plan and a different company removes the damage, as Texas law requires. Call the number on this page to be connected with a local mold remediation company in La Porte.
La Porte and the bay
La Porte sits on the Galveston Bay shoreline at the bay's northwest end, about 25 miles from downtown Houston, near the mouths of Buffalo Bayou and the San Jacinto River and next to the Port of Houston's Bayport Terminal. Hurricanes have hit the town since its resort days: the 1900 Galveston hurricane seriously damaged its attractions, a 1915 storm struck again, and a 1943 hurricane destroyed most of the tourist attractions that had grown up around the old Sylvan Beach resort. Today the city is known for many small 1940s frame houses alongside newer homes. Older frame homes that sit on pier-and-beam foundations can hold water underneath as well as in the walls.
What to do now
- Stop the water and get the house drying. If you can, aim for 24 to 48 hours, the window EPA gives before mold should be assumed.
- Photograph every wet room, the waterline and damaged contents.
- Pull wet rugs and furniture out of the rooms if it is safe to do so.
- Do not run the AC if water reached the air handler or ducts.
- Arrange a mold assessment. The consultant's protocol lists what comes out and how the area will be cleared.
- Hire a remediation company separate from the assessor and check it on TDLR's license search.

Cost factors
Angi's Houston cost data reports an average of $2,016 for mold removal, with a low-to-high range of $500 to $5,500. Flood jobs commonly exceed that, and national ranges (HomeGuide, 2026) run $15 to $30 per square foot. In La Porte, price depends on the wet area, how long it stayed wet, access under raised homes, cabinets and flooring, containment and the assessor's separate fees. After removal, rebuilding is permitted through the City of La Porte Inspection Services Division.
