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.
Wake Forest soil and why crawl spaces fail here
Wake Forest sits over Vance and Appling soils weathered from the Rolesville granite pluton. Saprolite gives way to shallow granite shelves that behave like an underground roof, redirecting infiltrating water sideways until it collects against footings and crawl space walls.
Water arriving from uphill saturates the perimeter, wicks into block, and keeps humidity in the 70s all summer. Fiberglass batts absorb that moisture, sag out of the joist bays, and leave the subfloor exposed to continuous vapor drive.
Downtown Wake Forest's century-old homes on brick piers and the newer Hasentree and Heritage builds need very different scopes, so an on-site assessment matters more here than a phone quote.
