In Gibsonton, attic and roof-cavity mold usually follows a roof leak after a storm, an overflowing AC drain or poor ventilation, and in mobile homes it often starts at a roof seam or vent boot. The job is to stop the leak, remove wet insulation and clean or replace affected wood or panels. Call the number on this page to be connected with a local mold remediation company in Gibsonton.

Gibsonton in brief
Gibsonton sits where the Alafia River meets Hillsborough Bay, with U.S. 41 through its center. About 27 percent of homes are mobile homes and roughly 18 percent of housing was built before 1980, so a lot of roofs here are older or have been patched. Hurricane Helene in 2024 flooded most homes on Oak Street, a peninsula into the river. Surge seldom reaches an attic, but wind-driven rain during a storm does, and a flooded house left closed up raises humidity all the way up to the roof deck.
What to do now
- Find out whether water is still coming in. Look for a fresh drip or wet insulation after the next rain.
- If the roof is leaking and you can do it safely, have it tarped or patched before any mold work.
- Check the AC drain pan and condensate line if the air handler is overhead. EPA advises keeping both clean and flowing.
- Take photos of the growth and any ceiling marks below it.
- Leave the growth alone; scraping or sweeping it spreads spores into the house.
- If the air handler or ducts may be involved, switch the HVAC off, as EPA recommends.

What you see and what usually causes it
| What you see | Likely cause |
|---|---|
| Dark spotting near a ridge, valley or plumbing vent | Roof or flashing leak |
| Sagging or stained ceiling panels in a mobile home | Roof seam, vent boot or skylight leak into the cavity |
| Wet, matted insulation beside the air handler | Clogged condensate line or rusted pan |
| Growth concentrated above a bathroom | Exhaust fan duct ending in the attic |
| Even, light spotting across the whole deck | Blocked soffit vents and trapped humid air |
Cost factors
Angi reports attic mold remediation in the Tampa area typically falls between $1,075 and $4,300. A small patch over one bathroom sits near the low end; a full attic of decking plus insulation sits toward the top. Price also depends on whether ceiling panels in a mobile home need replacing, how much room there is to work, and whether roof or AC repairs are billed separately, as they usually are.
