⚡ QUICK ANSWER A Carolina crawl space inspection covers seven areas: moisture and standing water, structural wood condition, insulation, vapour barrier, pests and wildlife, mechanical systems (HVAC, plumbing, electrical), and ventilation.

⚡ QUICK ANSWER Crawl space wood rot is fungal decay of floor joists, sill plates, and subfloor caused by sustained moisture above 19% wood moisture content. In Carolina crawl spaces, wood rot is not a rare problem — it is the predictable outcome of years of uncontrolled humidity. The good news is that early-stage rot…
