Hidden Moisture: What Long Island Homes Teach Us About Water Damage
After every big storm on Long Island, I see the same issue—homes that look dry but aren’t. A recent case showed 78% indoor humidity and wall studs at 25% moisture content. Six days of controlled drying (dehumidifiers + airflow) brought readings down below 15%, preventing mold.
A few quick lessons from the field:
-
Act within 24–48 hours after a leak or flood.
-
Use moisture meters or hygrometers—don’t rely on sight or touch.
-
Track readings until materials reach normal levels (around 8–15% MC for wood).
-
Keep gutters clear and sump pumps tested before storm season.
Anyone else tracking drying data or using instruments after storms? Curious what’s working best for other pros in coastal areas.
