Seminole saw heavy flooding in Helene and Milton, and walls that took on water then can still hide mold if the drywall and insulation weren't removed and dried. Everyday leaks from plumbing, roofs and AC lines cause the rest. Fixing it means opening the wall, removing what's wet and drying the framing before rebuilding. Call the number on this page to be connected with a local mold remediation company in Seminole.

Local conditions
The Tampa Bay Times reported that Helene and Milton in 2024 were called the worst storms in Seminole's history. The city manager said hundreds of single-family homes were damaged, and residents of Grove Terrace reported heavy flooding. Homes that were patched quickly after the storms sometimes had drywall replaced only up to the visible water line, leaving wet insulation or framing behind. That's the kind of wall that develops a musty smell months later. Pinellas County reminds residents that everyone in the county lives in a flood zone and that standard homeowners and renters policies typically don't cover flood. Outside storm season, Seminole walls get wet the same way walls do across the region: AC condensate overflows, supply line leaks and roof or window failures. Because the air conditioner runs most of the year, a slow drip from an air handler closet can keep one wall damp for a long time before a stain appears.
Patch it or open it?
| Situation | Wipe and watch | Open the wall |
|---|---|---|
| Small surface spots, firm drywall, no smell | Yes, after fixing humidity | No |
| Stain returns or spreads within weeks | No | Yes |
| Wall was under storm water, even briefly | No | Yes, check the insulation and plates |
| Musty smell with no visible growth | No | Consider an assessment first |

Signs to look for
- New drywall from a storm repair that is already staining at the bottom
- Gaps between baseboard and floor where the trim has shrunk or swollen
- Outlets on exterior walls that smell damp when the cover is removed
- A sharp smell after rain in one room
Timing
EPA says to dry wet materials within 24 to 48 hours and to assume mold if a flooded home couldn't be dried in that window. If your walls were repaired fast after the 2024 storms, it's worth having suspect areas checked, especially before the next hurricane season starts in June. Permits for drywall and structural work inside city limits come from the City of Seminole Building Division on 113th Street; addresses with a Seminole mailing address in unincorporated Pinellas go to the county. Renters can contact City of Seminole Code Enforcement, or Pinellas County Code Enforcement for unincorporated addresses.
