Crawl Space Encapsulation Before

Most homeowners have issues with cobwebs, water stains, spiders, drafts, and some without concrete or gravel and water management interior drainage system resulting in soggy dirt floors.
Crawl space encapsulation materials are installed to prevent moisture mold mildew and rodent issues. The moisture barrier also creates a clean durable finished space suitable for storage and climate control.
