How BAM Installs Crawl Space Vapor Barriers in Runnells
We start with a full inspection and moisture assessment to locate water entry, high-humidity zones, and damaged insulation. Technicians remove debris, repair or replace compromised insulation, and install a heavy-duty 20–30 mil polyethylene vapor barrier with overlapped seams sealed using waterproof tape. The barrier is mechanically fastened to the foundation and sealed around piers, plumbing penetrations and the access hatch; optional encapsulation includes a sealed hatch and commercial-grade dehumidifier. A final inspection and moisture reading confirm the crawl space meets BAM performance standards.
Runnells sits on expansive Iowa clay that holds groundwater and amplifies freeze-thaw movement, which pushes moisture into crawl spaces. A properly installed vapor barrier reduces humidity-driven mold, wood rot and foundation stress common to Polk County homes.

Look for musty odors, visible mold or mildew, damp or sagging insulation, increased allergy symptoms, or higher-than-normal humidity in the home; Iowa's clay soils and seasonal freeze-thaw cycles make these issues more likely.
