Thonotosassa is an unincorporated community in northeastern Hillsborough County bordered by the Hillsborough River and home to Lake Thonotosassa. Mold in local homes usually follows humidity, AC moisture and leaks. Call the number on this page to be connected with a local mold remediation company in Thonotosassa.

Mold services in Thonotosassa
Thonotosassa sits about 14 miles from Tampa, framed by the Hillsborough River to the north, I-4 to the south and I-75 to the west. Lake Thonotosassa is the area's namesake, and U.S. 301, Fort King Road and Morris Bridge Road are the main routes. The community is mostly urban but about 23 percent rural, so homes range from subdivision houses to properties on larger lots.
Moisture sources around the lake and river
Living near water raises outdoor humidity, and Tampa Bay's long summers do the rest. Inside, mold usually starts in one of a few places: the air handler closet, where a clogged condensate line overflows; the attic, after a roof leak; under sinks and behind appliances, where small plumbing leaks go unnoticed; and bathrooms that don't vent well. EPA recommends keeping indoor humidity below 60 percent and drying any wet area within 24 to 48 hours.
Rural homes and wells
On rural properties with private wells, flooding raises another concern. The Florida Department of Health in Hillsborough County advises disinfecting a private well after it has been flooded and boiling water if you're unsure it's safe. That's a separate job from mold remediation, but it belongs on the list if water reached the wellhead.
Flood maps and their limits
Hillsborough County explains that high-risk Special Flood Hazard Areas, Zones A and V, have a 1 percent annual chance of flooding, and that FEMA flood maps drive insurance and building requirements. The county also notes its floodplain maps don't account for coastal storm surge, and most homeowner policies don't cover flood damage.
County offices for Thonotosassa
As an unincorporated area, Thonotosassa gets building permits from Hillsborough County Development Services. After storms, structural repairs in a Special Flood Hazard Area need a permit. Cosmetic work such as drywall removal and replacement doesn't, though the county asks for its Substantial Damage packet.
Renters have a useful option here. Hillsborough County Code Enforcement handles housing-standards complaints in unincorporated areas, and its report-a-violation page lists mold along with A/C and heating among those standards. Reports go through the county's online form, and anonymous reports aren't accepted. For health questions, contact the Florida Department of Health in Hillsborough County.
What happens next
When you call, you'll be connected with an independent local company. Florida's s. 468.8419 means the company that assesses a structure can't remediate it within 12 months, and the remediator can't assess it, so assessment and removal are normally separate hires. Ask the remediator about their Florida mold remediator license and check it on DBPR's online search.
