Crews excavate to the footing, apply a membrane coating, install French drains and footing drain tile, and regrade the lot so runoff moves away from the crawl space.
Hillsborough soil and why crawl spaces fail here
Enon and Wilkes soils near Hillsborough form over slate and mafic rock with shallow, poorly drained profiles. The Eno River plain adds persistent atmospheric humidity that keeps crawl space air near saturation for much of the warm season.
Sustained high humidity feeds surface fungus across subfloor sheathing and softens old-growth joists until floors feel bouncy underfoot. Historic homes with hand-hewn sills are especially vulnerable at the sill-to-pier contact points.
Preservation-minded repairs matter in Hillsborough's historic district, where replacing original framing is a last resort rather than a default.
