Raleigh soil and why crawl spaces fail here
Raleigh sits on the Cecil soil series, a red clay loam weathered from granite and gneiss of the Raleigh Belt. Beneath the topsoil, dense clay subsoil sits on saprolite and shallow bedrock, so the 46 inches of rain the city receives each year cannot percolate downward. Water moves laterally instead, riding the top of the clay until it reaches a foundation footing.
Inside-the-Beltline homes from the 1940s through 1960s were built with open vents and bare dirt floors. The stack effect pulls that soil dampness up through the floor system and into ductwork, seeding Cladosporium colonies on subfloor sheathing and carrying musty air into bedrooms upstairs.
From Five Points and Hayes Barton to Brier Creek and Wakefield, Raleigh's housing stock spans eighty years of construction standards, and almost none of the pre-2005 crawl spaces were sealed.
