Crawl Space Vapor Barrier Experts in Des Moines
Des Moines homeowners face persistent crawl space moisture from Polk County's clay soils and fluctuating water table.

We focus on stopping ground moisture, preventing mold, and protecting floor systems and HVAC equipment with professional, code-compliant work.
How BAM Fixes Crawl Space Vapor Barriers in Des Moines
Our process begins with a full crawl space inspection to locate water entry, drainage needs, and insulation issues specific to Des Moines homes. Technicians remove debris, repair or install perimeter drains and sump pumps if needed, then install a heavy-duty 15–20 mil polyethylene vapor barrier with taped seams and sealed edges to footings and piers. For full encapsulation we seal vents, connect the barrier to foundation walls and piers, and recommend dehumidification or targeted ventilation based on seasonal Polk County humidity. Every job finishes with moisture testing and customer review.
Des Moines properties—many built on expansive Iowa clay—experience moisture migration and freeze–thaw movement that can force dampness into crawl spaces. A properly installed vapor barrier prevents ground vapor, lowers humidity, and reduces the risk of mold, wood rot, and HVAC inefficiency.
