Salt Air and Storm History on a Barrier Island
Dauphin Island sits at the mouth of Mobile Bay and has been rebuilt more than once -- Hurricane Frederic destroyed its bridge in 1979, and Hurricane Katrina split the island itself in 2005, a breach the state didn't finish repairing until 2014. Homes here are built to survive direct Gulf exposure, but that same exposure means salt-laden humidity is a constant presence, not an occasional storm event.
Elevated Construction Doesn't Eliminate Moisture Risk
Pier-supported, elevated homes are standard on Dauphin Island, and while that construction style keeps living space above storm surge, the underside framing, utility runs, and any enclosed lower-level storage still need real ventilation to keep salt air and Gulf humidity from becoming a mold source.

Assessing a Storm-Hardened Structure
On the island, checking pier framing, under-house utility chases, and roof penetrations matters as much as anything found inside the living space itself.
