St. Petersburg's older housing, with a median build year of 1969, and Helene's surge of more than 6 feet in neighborhoods like Shore Acres make mold a common follow-up to leaks and flooding. Remediation means stopping the moisture, removing moldy materials behind containment and drying the house before you rebuild. Call the number on this page to be connected with a local mold remediation company in St. Petersburg.

Signs of a mold problem
- Drywall that stayed damp after floodwater receded
- Paint blistering or peeling on plaster walls in an older home
- Mold on the underside of furniture or at the back of closets
- A musty smell from the AC that lingers after the system shuts off
- Repeat growth on a bathroom ceiling where the exhaust fan doesn't do its job
What's behind mold in St. Petersburg
The city reported more than 6 feet of storm surge during Helene in 2024. Shore Acres was among the hardest-hit neighborhoods, with some homeowners saying water reached their doorknobs, and one family climbed into their attic to stay above it. Fire Rescue boats went to Shore Acres, Snell Isle and Venetian Isles, and more than 100 miles of city roads were affected by flooding. FOX 13 described it as Shore Acres' fourth flooding event in four years, so some homes have been through repeated wetting and partial repairs.
Away from the water, the age of the housing does the damage. With a median build year of 1969, many homes have older roofs, plumbing and ductwork. About 37 percent of occupied homes are rented, and renters with leaks a landlord won't fix can report code issues through the city's Codes Compliance Assistance office.

What affects cost
Angi reports a typical Tampa-area job at $1,347 to $3,778 and a whole-house project at $10,750 to $32,250, the range heavily flooded homes can approach. HomeAdvisor puts the typical Tampa job at $1,248 to $2,550. In St. Petersburg, expect the scope to depend on flood height, plaster versus drywall, the number of rooms, any duct contamination and the rebuild. The city's 49% Rule matters here: in flood hazard areas, if repair and improvement costs reach 49 percent of the building's pre-storm market value, the structure must meet current zoning, building and floodplain rules. Storm-damaged properties need a permit before repair, applied for online with the "Storm Related Damage" user class through City of St. Petersburg Building & Permitting.
What happens when you call
You're connected with an independent local remediation company. They'll ask about the water source, how long it's been wet and how much area is affected, then schedule a visit and give you a written scope. Under Florida law the remediator can't assess or clear the same structure within 12 months, so testing comes from a separate mold assessor.
