How BAM Installs Crawl Space Vapor Barriers in West Des Moines
We begin with a thorough crawl space inspection to locate water entry, damaged insulation, and soil contact areas common in Polk County homes. Technicians remove debris, grade where needed, and install a minimum 20–30 mil commercial‑grade polyethylene liner, sealing seams with industry‑grade tape and mechanically fastening the barrier to foundation walls. Perimeter sealing, vapor‑tight duct connections, and tie‑ins to existing sump or drainage systems are completed to create a continuous moisture barrier. When needed we add insulation and decommission vents to maintain stable, dry conditions tailored to West Des Moines climate patterns.
West Des Moines homeowners need vapor barriers because Iowa clay soil retains moisture and seasonal freeze‑thaw movement pushes dampness upward into crawl spaces. A properly installed barrier reduces humidity, prevents mold and wood rot, and helps stabilize indoor comfort and energy bills.
