Homes near Reidville Road and the Inland Port Greer (nearby) corridor frequently show the same progression: ground moisture evaporates into the crawl space, humid outdoor air enters through open foundation vents, and relative humidity climbs above the 60% threshold where mold grows on floor joists and subfloor.
