More about our Crawl Space Products

For more than 50 years now, it's been consistently proven that vented crawl spaces result in mold, rot, and high energy bills.

About fifteen years ago, Basement Systems found a solution for this building epidemic -- one that has been successfully in hundreds of thousands of homes since it was first designed.

By installing a crawl space vapor barrier system in a home, we can best control your crawl space's environment, while eliminating the intrusion of humidity, cold air, and pests from outside your home.

Our system includes a crawl space liner installed on the walls and floors, airtight vent covers and doors, and a crawl space dehumidifier.

In cases with groundwater flooding, we also install a sump pump and perimeter drainage system.
