Savannah's average summer relative humidity exceeds 70 percent, and secondary mold can begin in as little as 24 hours after saturation. Hurricane Matthew caused widespread flooding across Chatham County in 2016, and the NFIP maintains active policies throughout the county — including the Historic District, Ardsley Park, and Hudson Hill — confirming ongoing federal recognition of flood exposure.
The Savannah River and aging combined sewer infrastructure generate consistent supply-line failures and storm drain overflows during heavy rain. Historic homes with heart-pine floors and plaster walls require specialized drying — original hardwood typically needs five to eight days, plaster walls seven to fourteen — making contractor experience with historic materials essential.
Georgia follows the IICRC S500 standard. Ask for written moisture logs and confirm your policy includes replacement cost coverage for historic materials, not just actual cash value. Call 24/7 for emergency response in Savannah or Chatham County now.
