Mildew in Kathleen homes usually grows on bathroom ceilings, closet walls, window frames and around AC vents, where humid Polk County air settles and doesn't dry. EPA says patches under about 10 square feet on hard surfaces can usually be cleaned by the homeowner once the moisture is fixed. For larger or returning growth, call the number on this page to be connected with a local mold remediation company in Kathleen.

Kathleen and indoor moisture
Kathleen is an unincorporated community in Polk County, part of the Lakeland-Winter Haven area and about 28 miles from Tampa. It's inland, so storm surge isn't the issue here. The mildew drivers are central Florida's long, humid summers, afternoon downpours and air conditioners that run most of the year. An AC drain line that clogs, a bath fan that isn't used, or a closet on a west-facing wall with no air movement can grow a film of mildew in a few weeks. Florida DOH advises drying wet building materials and carpet within 24 hours after water gets in, since common molds can take hold when water stands that long.
What to do now
- Check for the source: look at the AC drain pan, under sinks, around the tub and at ceiling stains under the roof.
- Dry the room with the AC, a fan and a dehumidifier, and pull wet items out.
- For a small spot, wear gloves, goggles and an N-95 respirator, and open a window.
- Clean hard surfaces with detergent and water and let them dry completely.
- Replace caulk that stays dark instead of sealing over it.
- Bring in a company if the area is larger than about 10 square feet, keeps returning, or is on soft drywall or ceiling material.

What you see and the likely cause
| What you see | Likely cause |
|---|---|
| Black dots on the shower ceiling | Steam and a weak or unused fan |
| Musty smell near the air handler | Clogged condensate line or wet drain pan |
| Mildew on shoes and bags in a closet | Still, humid air |
| Ceiling stain with spotting | Roof or flashing leak |
| Spots at the base of a vanity | Slow plumbing drip |
Cost factors
Angi reports Tampa-area bathroom mold remediation typically runs $525 to $1,075 and larger jobs $1,347 to $3,778. Those are regional ranges, not Polk County quotes. Kathleen pricing depends on how far the growth reaches, whether drywall or flooring has to be replaced, travel and access, and what it takes to fix the moisture. If rebuilding is needed, Polk County's Building Division issues permits for unincorporated Kathleen from its office in Bartow.
