Gibsonton homes face two routes to AC mold: everyday condensation in a system that runs most of the year, and floodwater like the Helene flooding on Oak Street reaching ducts or air handlers. In many manufactured homes the ducts run through the underbelly, where moisture can sit unnoticed. Call the number on this page to be connected with a local mold remediation company in Gibsonton.

Gibsonton at a glance
Gibsonton sits where the Alafia River meets Hillsborough Bay, with U.S. 41 running through its center and a long history as the winter home of carnival and circus performers. About 27 percent of its housing units are mobile homes, roughly two-thirds are detached single-family houses, and the median build year is 2002, though about 17.7 percent of units predate 1980. During Helene in 2024, most homes on Oak Street, a peninsula jutting into the Alafia, flooded; residents said the street had never flooded before, and one family was rescued by boat from waist-deep water.
What to do now
- Switch the system off. EPA says running a contaminated system can spread mold through the house.
- Look at the drain. Find where the condensate line exits and see whether it drips on a hot afternoon, then check the pan for standing water.
- In a manufactured home, look under the skirting. Torn belly fabric, sagging insulation or water under the home means the floor ducts may be wet.
- Note any flood contact. If water touched ducts, a return or the air handler and the house wasn't dried within 24 to 48 hours, EPA says to assume mold growth.
- Photograph registers, stains and damaged duct before anything is removed, for your records and your insurer.
- Ask for a scope that covers the moisture source as well as the mold.

What you see and what it usually means
| What you see | Likely cause |
|---|---|
| Musty smell at startup | Growth on the coil, pan or blower |
| Water on the closet floor | Clogged condensate line or cracked pan |
| Spots on vent covers | Condensation on cold registers, or growth inside the duct |
| Soft floor or musty skirting | Wet belly insulation or a leaking floor duct in a manufactured home |
| Water lines on lower walls | Flood contact with returns or ductwork |
Cost factors
Angi's typical Tampa-area range for HVAC mold remediation is $3,225 to $10,750. Expect the price to reflect how much duct must be replaced (EPA says wet or moldy duct insulation can't be cleaned effectively), how hard the belly or attic is to reach, whether an HVAC contractor has to replace the air handler, and how much other flood-damaged material is involved. Rebuilding or structural repairs in a Special Flood Hazard Area need a permit from Hillsborough County Development Services.
