If you've lived in Tampa through even one summer, you know the drill: 90% humidity outside, AC working overtime inside, and that telltale musty smell creeping into bathrooms and closets. Mold doesn't need much — just moisture, warmth, and 24–48 hours. Florida supplies the first two for free.

The good news: prevention is mostly about airflow and a five-minute weekly habit. Here's the routine our crews recommend to every Tampa client.

1. Squeegee the shower — every time

The single highest-impact habit on this list. A $10 squeegee run over shower walls and glass after each use removes the standing water mold feeds on. It takes 30 seconds and also prevents hard-water spots.

2. Run the bathroom fan longer than you think

Most people turn the exhaust fan off when they leave the bathroom. In Florida, leave it running 20–30 minutes after a shower — that's how long it takes to actually clear the moisture. No fan? Crack the door and a window instead.

3. Keep indoor humidity under 55%

  • A cheap hygrometer (under $15) tells you where you stand.
  • Set the AC fan to AUTO, not ON — running the fan continuously re-evaporates moisture off the cold coil and pumps it back into the house.
  • For chronically damp rooms or closets, a small dehumidifier or even moisture-absorber tubs make a real difference.

4. Don't forget closets and AC vents

Closets on exterior walls are mold hotspots because air barely moves in them. Leave doors cracked, don't pack clothing wall-to-wall, and skip storing anything damp. Glance at your AC supply vents monthly — black speckling around the louvers is an early warning that your system needs attention.

5. Treat mildew the moment you see it

Small surface mildew on tile, grout, or painted walls: spray with a mix of one part white vinegar to one part water, let it sit 10 minutes, scrub, and dry the area thoroughly. For tougher spots, a bathroom mold-and-mildew cleaner with the fan running works fine.

Safety first: never mix bleach with vinegar or ammonia-based cleaners — the combination releases toxic gas. Pick one product, finish, and rinse before ever switching to another.
Pro tip: if a musty smell persists after cleaning, the source is usually hidden — under a sink, behind a washer, or inside the AC air handler. Mold larger than about 10 square feet, or anything inside walls or HVAC, is a job for a remediation specialist, not a sponge.

Stay ahead of the humidity and mold never gets a foothold. Fall behind, and Tampa's climate will happily take the opening — so put the squeegee where you can't ignore it.
