Mold in Walls & Drywall in Gibsonton, FL

A local picture

Gibsonton sits where the Alafia River meets Hillsborough Bay, with U.S. 41 running through the middle of town. Hurricane Helene in 2024 flooded most of the homes on Oak Street, a peninsula that pushes into the river, and residents there said the street had never flooded before; one family was rescued by boat from waist-deep water. About 27 percent of homes here are mobile homes, and roughly 18 percent of housing was built before 1980, so thin interior panels and aging roofs are part of the picture alongside newer slab houses.

What to do now

1. Stop the water. Shut the supply valve, clear the AC drain line, or tarp a roof leak if you can do it safely.
2. Photograph the stains, the water line and any soft spots before anything is moved.
3. Pull furniture a few feet away from the wall so it can be inspected and dried.
4. Don't sand, scrub or paint the area. EPA advises against painting or caulking over mold.
5. If the wall stayed wet more than 24 to 48 hours, plan on the drywall and insulation coming out.
6. Keep anyone with asthma or a weakened immune system out of the room, as EPA advises.
7. Call your insurer if the water came from a storm. Flood damage usually needs a separate flood policy.

What you see and what it usually means

Cost factors

Angi reports that wall remediation around Tampa typically falls between $1,075 and $21,500, and that many companies charge about $10 to $25 per square foot. The low end fits one wall in one room; the high end fits a house where floodwater reached every room. What pushes a job up or down:

• Square footage of drywall and insulation removed
• Whether a mobile home's wall panels need full replacement
• Containment needs, including how many rooms are involved
• Rebuild work afterward, such as new drywall, trim and paint

Gibsonton is unincorporated, so Hillsborough County Development Services handles any structural permits during the rebuild.
