Clay soil and hidden moisture
Upstate red clay drains slowly and pressures foundations, pushing water into basements and crawl spaces, and the humidity lets it turn to mold quickly. Knowing how long drywall takes to dry helps set expectations after a leak.
Bottom line
Greenville homeowners should watch foothill runoff and crawl spaces during storms, keep drainage directing water away, and dry intrusion completely.
