Cary soil and why crawl spaces fail here
Cary's Cecil-Appling complex carries a sandy surface horizon over a stiff clay hardpan. Rain infiltrates the first several inches quickly, then stalls on the hardpan and spreads out under the home as a shallow perched table that never fully drains between storms.
Executive-scale footprints in Preston, Lochmere, and Amberly enclose enormous volumes of ground vapor. That vapor condenses on cool ductwork and drives moisture content in the subfloor above 18%, which shows up as cupped and crowned hardwood in formal living areas.
Cary homeowners typically hold their homes long term and expect documented humidity readings before and after work, not just a plastic liner.
