Black Mold Removal in Longboat Key, FL

Signs to watch for

• Black spotting low on drywall in a ground-floor unit that took water
• Mold on closet walls and stored linens in a condo that was closed up
• Dark stains around sliding doors and window frames facing the Gulf
• A musty smell when the AC is switched back on after months away
• Bubbling paint or loose baseboards after a storm

EPA says color doesn't tell you how risky a mold is. Less than about 10 square feet on a hard surface is usually a homeowner job; anything larger, or inside walls, needs a remediation company.

Longboat Key conditions

Longboat Key is a barrier island between Sarasota Bay and the Gulf, with Longboat Pass at its north end. During Helene in 2024, surge reached up to 8 feet on parts of the key. The Village, one of its lowest areas, had roughly 3 to 4 feet of water around homes and standing water inside some, ruining drywall and belongings; Gulfside Road and other mid-Key neighborhoods were badly damaged too. A 1921 hurricane once destroyed most of the island's buildings. Condominiums are a major housing type, and a large share of units are seasonal, so a leak in a closed unit can grow for weeks before anyone opens the door.

What affects cost

Angi reports typical Tampa-area remediation at $1,347 to $3,778 and HomeAdvisor at $1,248 to $2,550. Those are regional figures from about 40 miles north, not quotes. On the key, cost rises with the amount of drywall and flooring removed after surge, condo building rules on work hours and debris, the number of units affected by a shared leak, HVAC involvement and the rebuild. The town notes its barrier-island location brings building code standards that don't apply on the mainland, which can affect repairs.

What happens when you call

You'll be connected with an independent local remediation company. Expect questions about whether surge or a leak caused the damage, how long the unit sat wet and whether the association is involved. After a visit and written scope, removal proceeds under containment. A separate assessor handles any clearance check under Florida's 12-month rule, and the Town of Longboat Key Planning, Zoning & Building Department handles permits on both the Sarasota and Manatee sides.
