Lowcountry and coastal South Carolina
Charleston, Mount Pleasant, Summerville, North Charleston, Goose Creek, Johns Island, Beaufort, Port Royal, Bluffton, Hilton Head and Hardeeville. High humidity, shallow groundwater and heavy rainfall drive drainage and dehumidification work here.
Grand Strand
Myrtle Beach, North Myrtle Beach, Conway, Surfside Beach, Murrells Inlet and Pawleys Island. Sandy soils and a high seasonal water table keep crawl spaces damp even between storms.
Midlands
Columbia, Lexington, Irmo, West Columbia and Cayce. Long humid summers and exposed crawl space soil are the usual starting point, with sagging floors appearing in older housing stock.
Pee Dee
Florence, Darlington and surrounding Pee Dee communities, where flat lots complicate drainage routing.
Upstate
Greenville, Spartanburg, Greer, Anderson, Easley and Simpsonville. Clay-heavy soils hold water against foundations, and floor support questions come up frequently in older homes.
