Why mold is common in Miami
Miami International Airport averages 67.4 inches of rain a year, and most of it falls during the wet season from mid-May to mid-October. June and September each bring more than 10 inches. Average relative humidity sits around 73%, so drywall, carpet, and wood that get wet rarely dry out on their own.
The housing stock adds its own risks. About half of Miami's homes are in buildings with 20 or more units, where a leak in one condo can travel through shared walls, ceilings, and AC chases into the next. About half of all housing units were built before 1980, long before current roof, window, and plumbing standards.
Storms are the third factor. When Hurricane Wilma broke windows in downtown high-rises in 2005, rain soaked interiors floor by floor. After any storm or plumbing leak, the EPA advises drying wet materials within 24 to 48 hours; after that, mold growth becomes likely.

Florida mold licensing: what to check
Florida licenses mold assessors and mold remediators through the Department of Business and Professional Regulation (DBPR). Before anyone takes samples or opens a wall in your Miami home, ask for the license number and look it up at myfloridalicense.com.
State law also keeps the two jobs apart. A company that assessed your home may not remediate it within the next 12 months, with a narrow exception for certain certified contractors, and a remediator may not assess a home it remediated in that window. Most Miami homeowners use one company to find the problem and another to fix it.
Will insurance cover it?
Most Florida homeowners policies cap mold coverage at a set amount, often $10,000, and pay only when mold follows a covered sudden loss such as a burst pipe. Mold from slow leaks or long-term humidity is usually excluded.
In a condo, two policies may be involved. The association's master policy generally covers common elements, while your HO-6 policy covers the interior of your unit. Report water damage to the association and to your insurer right away, and photograph everything before cleanup. Our guide on whether insurance covers mold explains the details.
