How Quickly Does Mold Grow After Flooding? What to Do in the First 48 Hours
Floodwater may be gone, but the clock is still ticking. โฑ๏ธ๐ง Mold can begin developing on damp drywall, insulation, carpet, and wood within just 24โ48 hours.
During the first two days, homeowners should document the damage, stop the water source, remove standing water, begin professional drying, and remove materials that cannot be completely dried. Even when the surface looks normal, hidden moisture may remain behind walls, baseboards, and flooring. ๐ ๐
A professional Mold Inspection can help locate hidden moisture and possible mold before the damage spreads or affects your indoor air quality.
