Longboat Key is a barrier island where Helene's surge reached up to 8 feet in places and left 3 to 4 feet of water around homes in the Village, ruining drywall and belongings. Remediation after that, or after an AC or roof leak in a condo or house, means removing wet and moldy materials, drying the structure and fixing the source. Call the number on this page to be connected with a local mold remediation company in Longboat Key.

Signs to check for
- Drywall, baseboards or cabinets that sat in floodwater, even briefly
- A musty smell in a unit that has been closed up for part of the year
- Spotting around sliding doors and window frames
- Stains on ceilings below an AC closet or a neighbor's unit
- Mold on items stored in ground-level closets or garages
Local conditions on Longboat Key
The town sits on a barrier island south of Anna Maria Island, with the Gulf of Mexico on one side, Sarasota Bay on the other and Longboat Pass at the north end. In Helene, surge reached up to 8 feet on parts of the key. The Village, one of its lowest-lying areas, had roughly 3 to 4 feet of water around homes and standing water inside some houses that ruined drywall and belongings; Gulfside Road and other mid-Key neighborhoods were also badly damaged. The island's storm history runs deep: a 1921 hurricane destroyed most of its farmland and buildings, including the post office.
Condominiums are a major housing type, and a large share of homes are seasonal. A unit left closed for months can grow mold from a slow leak or high humidity with nobody there to notice. The Florida Department of Health advises drying wet materials and carpet within 24 hours after water gets in.

What affects the cost
Angi reports Tampa-area remediation typically running $1,347 to $3,778 and HomeAdvisor reports $1,248 to $2,550; treat both as regional ranges. On the key, the main cost drivers are flood height and how much drywall comes out, condo building rules and access, the number of rooms contained, and whether the AC system needs cleaning. The Town of Longboat Key Planning, Zoning & Building Department handles permits for both the Sarasota and Manatee sides of the island, and the barrier-island location brings building code standards that don't apply on the mainland, so ask about them before rebuilding.
What happens when you call
You'll be connected with an independent remediation company. Share the address, the water source and how long the space was wet. If you're away for the season, ask whether a building manager can provide access. The company inspects, measures moisture and writes a scope. Clearance testing comes from a separate mold assessor, as Florida's s. 468.8419 bars the remediator from assessing its own job within 12 months.
