Before Crawl Space Repair:

Moisture Threatening the Home’s Health
The homeowner reached out to AFS with growing concerns about standing water and humidity in their crawl space. Water from rain and surrounding clay soil was seeping in, creating an ideal environment for mold and wood rot.

Poor Air Quality and Structural Risks
The moisture wasn’t just a comfort issue—it posed a serious risk to the home’s structure and indoor air quality. Without intervention, the crawl space was becoming a source of allergens, mold, and foundation problems.
After Crawl Space Repair:

Drainage and Humidity Control
An interior drainage system with a sump pump was installed to manage any groundwater that might collect beneath the barrier. A commercial-grade dehumidifier was added to keep the crawl space at a consistent 55% relative humidity.

Full Encapsulation Across 3,000 Sq. Ft.
Led by foreman Dean Sharpe, the AFS team installed a 120-mil vapor barrier to fully encapsulate the crawl space and isolate it from ground moisture. The barrier covered the entire 3,000 sq. ft. space, sealing off key entry points for water.
