What is Crawl Space Encapsulation

Crawl space encapsulation is a specialized procedure designed to protect the crawl space beneath a building from moisture, mold, pests, and other environmental hazards.

It involves the installation of a thick, durable polyethylene barrier that covers the entire area, including the floors, walls, and potentially the ceiling.  

Moreover, by sealing the crawl space, encapsulation helps to improve overall air quality in the home and enhances the efficiency of heating and cooling systems, leading to potential energy savings.

This method not only helps maintain the structural integrity of the building but also turns a previously vulnerable area into a clean, dry, and energy-efficient space.

Before and After
Crawl Space Encapsulation

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.

Crawl space encapsulation done right includes a thermal barrier using insulation. Common insulation materials installed are spray foam around seams and box sill, and a vapor barrier over gravel or dirt floors. If the floor is concrete, no vapor barrier is necessary.

Spray Foam Crawl Space Encapsulation

Control moisture from outside the crawlspace by extending gutter downspouts 4-6 ft from home, standing rain water management drain tile and more. Temperatures in the crawl space is neutral.

It is unconditioned (not heated or cooled by HVAC systems), as there is no reason to condition it to room temp. Crawlspace may need a dehumidifier if its prone to moisture from exterior water management and grading issues (flood zone or water runoff towards structure).
