Black mold in Dunedin homes usually grows where water lingered: walls that took surge from St. Joseph Sound, or older houses with tired roofs and plumbing. Removal means fixing the moisture, sealing off the area, cutting out colonized drywall and insulation and drying the structure.

My Dunedin house flooded. How much drywall has to come out?
As much as the water and the mold reached, plus a margin. In Baywood Shores after Helene in 2024, surge came over the seawall and homes throughout the neighborhood had walls cut out from the floor up to about five feet. The same neighborhood flooded in Idalia the year before, when residents found the tidal valves meant to keep water out weren't working. Soaked drywall and insulation that didn't dry within a day or two should be treated as moldy, even when the face looks clean. A remediation company will cut above the wet line, remove insulation, clean and dry the studs and check moisture readings before anything is rebuilt.
Why does an older Dunedin home keep growing black mold?
Age gives water more ways in. Dunedin's median home was built around 1976, about 61 percent of units date from before 1980, and the 1970s is the biggest single decade. Original roofs and flashing, galvanized supply lines, single-pane windows and AC systems added years after construction all leave damp spots. The removal is the same whatever color the mold is; EPA says color doesn't tell you how risky it is. The lasting fix is stopping the water: a repaired roof, a new supply line, a clear condensate drain, or a working bath fan.
Who handles permits and complaints in Dunedin?
Dunedin runs its own building department through Community Development, so permits for new drywall, structural repairs or post-storm work come from the city rather than Pinellas County. Renters with a leak the landlord won't fix can use the city's online Report a Violation form; the Code Compliance Division enforces the city code, the Florida Building Code and the International Property Maintenance Code.

A local note
From downtown Main Street to the Dunedin Causeway, Dunedin faces St. Joseph Sound and the Gulf beyond Honeymoon and Caladesi islands. DOH-Pinellas has warned that moisture from leaks or flooding speeds mold growth that keeps damaging materials long after a storm, so walls that look dry but smell musty deserve a second look. For any clearance check, use an assessor who didn't do the removal, as Florida's 12-month rule requires.
