Crawl Space Encapsulation in Renton, Serving the Issaquah, WA, Area

40% of the air you breathe comes from your crawl space.

With high levels of moisture, poor air circulation, and ample amounts of organic debris, your crawl space is the perfect breeding ground for mold & mildew and rodent damage that can cause poor air quality throughout the entire house. Moisture and the elements in your crawl space flow through the home from the “stack affect”. The upward airflow brings what is in your crawlspace and deposits it in your living environment through gaps in the floors, walls, and from poorly sealed heat ducting.

Moisture in the crawlspace is the most controllable factor to help prevent damage to your health and home. By isolating the wet and moist soil and damp foundation walls from the rest of your house structure with crawlspace encapsulation products you can stop the damaging effects caused by water.

The Perma Dry Waterproofing Clean and Dry liner system is a heavy gauge, 4-ply scrim reinforced plastic liner (like a pool liner) encapsulation product. This crawl space sealer is securely fashioned to foundation walls and sealed at all edges and overlaps to seal off the moisture from the rest of your home. Non-flammable and coated with an anti-microbial sealant, your home will be dryer, cleaner, and healthier from the ground up.

With our “conditioned crawl space” services, you can seal your crawlspace air vents from cold winter air and moisture.

Looking for something a little stronger and more permanent? Concrete for Crawl Spaces seals the dirt surface and is the only product to provide a 100% rodent free guarantee and provide sturdy storage space.
