Fort Myers homes built before 1980 in the River District and McGregor often have lath-and-plaster walls and slab-on-grade foundations that trap water after Lee County flooding. Post-flood mold treatment starts with moisture mapping using infrared cameras to locate saturation behind baseboards and under flooring that homeowners miss. Technicians remove affected porous materials like carpet pad and drywall up to 18 inches above the water line, then apply EPA-registered antimicrobials followed by HEPA air scrubbing to capture spores released during demolition.
The tropical savanna climate brings high humidity even in winter, so drying equipment must run longer than in drier regions. After Hurricane Ian many Cape Coral and Downtown Fort Myers properties showed mold returning within ten days because dehumidifiers were removed too soon. Treatment includes installing temporary containment barriers and monitoring moisture levels daily until readings stay below 12 percent on wood and 55 percent relative humidity in the air before any reconstruction begins.
In low-lying McGregor and near Centennial Park, storm surge or canal overflow can push water under cabinets and into HVAC returns. Post-flood mold treatment requires pulling registers, cleaning coils, and replacing insulation in ductwork that has wicked moisture. Technicians also inspect attics where roof leaks from wind-driven rain combine with flood water to create hidden colonies above ceilings that standard visual checks miss.
Technician insight
In Fort Myers the thing that catches most people out with Post-Flood Mold Treatment is how quickly spores take hold again once the sun comes out. Our tropical savanna humidity keeps wood and concrete damp for days after the water recedes, especially in older River District homes with poor slab drainage. Homeowners often pull fans too soon and the growth restarts behind baseboards within a week.
McGregor Home After Canal Overflow
Water entered a 1960s McGregor slab home through the garage and laundry room during heavy rains. Infrared scans showed saturation under the kitchen cabinets and into the HVAC return. Crews removed baseboards and lower drywall, dried the slab for six days, treated framing, and cleared the home before new flooring was installed.
