Dunedin homes face two main mold triggers: storm surge from St. Joseph Sound, which forced Baywood Shores owners to cut drywall out up to about five feet after Helene, and the aging roofs and plumbing of a housing stock that is mostly pre-1980. Remediation fixes the moisture, removes moldy materials and dries the structure. Call the number on this page to be connected with a local mold remediation company in Dunedin.

How far up the wall does flood-damaged drywall need to come out?
It depends on how high the water rose and how long it sat. After Helene's surge came over the seawall in Baywood Shores in 2024, walls throughout the neighborhood were cut out from the floor to about five feet, with furniture and appliances piled at the curb. A common approach is to remove drywall some distance above the visible water line, open the cavity, pull wet insulation and check the studs with a moisture meter before deciding where to stop. EPA's post-disaster guidance says that if a home couldn't be dried within 24 to 48 hours, you should assume mold is growing. Baywood Shores also flooded during Idalia in 2023, when one resident had about 18 inches of water inside, so some homes there may have older damage hidden behind newer repairs.
My house is from the 1970s. Is that a mold risk by itself?
Age alone doesn't grow mold, but it raises the odds of a leak. About 61 percent of Dunedin's housing was built before 1980, and the 1970s is the largest single decade. Original roof decking, old supply lines, aging window frames and ductwork that has been patched several times are common entry points. The classic signs are a ceiling stain that spreads after a storm, paint bubbling at the base of a wall and a musty closet on an outside wall.
I rent. Who can help if the landlord won't fix the leak?
About 29 percent of Dunedin homes are rented. Put your repair request in writing with photos. If the leak stays unfixed, the City of Dunedin Code Compliance Division enforces the city code, the Florida Building Code and the International Property Maintenance Code, and takes reports through its online Report a Violation form, which asks for your name and address.

Permits and rebuilding in Dunedin
Dunedin runs its own building department rather than relying on Pinellas County, so permits for new drywall, framing or other post-storm repairs come from the city's Community Development building and permitting staff. Under Florida law the remediation company can't also run the clearance check on your house within 12 months; a separate mold assessor handles that step.
