Largo mildew shows up on bathroom ceilings, around windows, in closets and under manufactured-home floors, and near McKay and Church creeks it can follow Milton's flooding. EPA says patches under about 10 square feet on hard surfaces are usually a homeowner job if the moisture is fixed; larger or returning growth needs a professional. Call the number on this page to be connected with a local mold remediation company in Largo.

Largo's housing and mildew
Largo's homes skew older and mixed: more than half were built before 1980, about a third in the 1970s alone, and mobile or manufactured homes make up about 26 percent of housing units, nearly as many as detached single-family houses. About 38 percent of occupied homes are rented. During Hurricane Milton in 2024, McKay Creek overflowed into homes including along Crescent Drive, and residents near Church Creek reported similar flooding. Rooms that took creek water need their drywall and flooring checked, not just wiped, while the rest of the city deals with the everyday kind: humid closets, steamy baths and old windows.
What to do now
- Look for the water source: a roof seam, a window corner, a drip under the sink, a sweating AC line, or dampness under a manufactured home.
- Dry the area with the AC, fans and a dehumidifier. EPA says to dry wet areas within 24 to 48 hours.
- Put on gloves, goggles and an N-95 respirator for small cleanups and ventilate the room.
- Scrub hard surfaces with detergent and water, rinse and dry completely.
- Remove moldy caulk and bag porous items that won't come clean.
- Call a company if the growth is larger than about 3 ft by 3 ft, the wall or floor is soft, or the area took creek water.

Signs and likely causes
| What you see | Likely cause |
|---|---|
| Gray spots on paneling in a manufactured home | Roof seam or window leak, or humid air under the floor |
| Spongy floor near a tub or toilet | Slow plumbing leak |
| Mildew band low on walls | Creek or rain flooding that wasn't dried fast |
| Dark film on 1970s window frames | Condensation on old single-pane glass |
| Musty supply vents | Humid air or a clogged AC drain |

Angi reports Tampa-area bathroom mold remediation typically costs $525 to $1,075 and crawl-space work $525 to $2,150; HomeAdvisor's typical Tampa range for mold jobs is $1,248 to $2,550. Those are regional figures, not quotes. A Largo price depends on how much material comes out, access under the home or behind cabinets, containment, and repairs to the leak itself. Inside city limits, drywall or floor rebuilding is permitted by the City of Largo Building Division; unincorporated Largo-area addresses go to Pinellas County.
