| Professional deep clean + reseal | Annually | Resets protection baseline |
Why Florida Showers Grow Mold Faster
In most of the country, bathroom humidity drops after a shower because ambient humidity is low. In Florida, ambient humidity is already 70–90%. Your bathroom never fully dries out. This constant moisture environment turns unsealed grout into a mold incubator within weeks, not months.
The exhaust fan is your most important tool. If your fan is loud, weak, or barely pulls air, replace it. A properly sized exhaust fan (80+ CFM for a standard bathroom) vents moisture outside rather than into the attic.
If mold has already set in, surface cleaning won't solve it. The roots (hyphae) grow beneath the grout surface. Our shower restoration service includes deep extraction, mold treatment, regrouting damaged areas, fresh caulking, and professional sealing. Call (772) 879-5722.
