Patented, proven basement waterproofing solutions

As part of the Basement Systems dealer network, we have access to the highest quality and most effective products for basement waterproofing. We can customize a drainage system for your basement’s specific needs, depending on your foundation type and your home’s unique condition. Our different sump pump systems can handle heavy water evacuation, and many feature battery backups, alarms, and extra pumps, reducing the chance of a basement flood to statistical insignificance.

Crawl space encapsulation, insulation, and support systems

With our patented solutions for crawl space encapsulation, we can repair moisture intrusion issues, mitigate mold or mildew growth, and prevent structural damage caused by wood rot. If you’re suffering from a sagging crawl space, we have support systems manufactured for that exact purpose. Don’t let your crawl space leave you exposed to asthma and allergy symptoms, foul odors, or property damage; contact the experts at Seattle Basement Systems!

We also provide insulation specifically designed for the crawl space. A properly encapsulated and insulated crawl space will bolster the energy efficiency of the home while also promoting healthy indoor air quality. Another additional benefit is that the floors above the crawl space will be much warmer after installing insulation.
