Crawl Space Services NW

Turn your crawl space into a clean healthy space

Crawl Space Services, a division of Perma Dry Waterproofing and Drainage, has the experience to repair all of your crawl space clean up and improvement needs. We don’t just do vapor barriers, we do it all. When we’re done, the result is a cleaner healthier home for you and your family.
From damaged insulation, construction debris, rodent and insect clean up to water problems, foundation cracks, mold and mildew remediation…One call solves it all!


Moisture in the crawl space 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 crawl space encapsulation products you can stop the damaging effects caused by water.



With our special blend of concrete for application in tight spaces, we seal all exposed dirt surfaces under your home with 3-4” inch thick permanent rigid concrete encapsulation barrier. It is the only material to provide a 100% guarantee of rodent control, while adding structural integrity to your foundation.



At Perma Dry Waterproofing, we take the time to assess the problem and determine the best way to solve it. As a result, what we make dry stays dry. In fact, we’re so confident in the quality of our work that we offer a written guarantee to back it up. Ask your System Design Specialists for a copy of our complete guarantee.
