Mold risk beneath elevated post-Hugo homes
Sullivan's Island is a barrier island where Hurricane Hugo damaged every home during its direct 1989 hit, and the elevated, piling-supported homes built in the rebuilding wave that followed still trap humidity in the crawlspace beneath the living area.
What that split means for mold risk
Elevated, post-Hugo homes trap humidity in the crawlspace beneath the living area, while older pre-1939 cottages may have less ventilation built in to begin with — different housing eras on this island need different moisture strategies.

What to describe
Tell us roughly when the home was built or rebuilt, whether it's elevated, and where you've noticed odor or moisture.
Regional humidity context
Charleston-area humidity runs 72% on average and closer to 79% in August; on a barrier island with a 2024 stormwater-improvement plan still underway, that moisture load stays a standing concern.
