Crawl Space Vapor Barrier

Excessive moisture and humidity in your crawl space might damage your property and risk your family’s health. That’s because water intrusion often leads to mold growth, dampness, wood rot, and pest infestations that jeopardize your home’s foundation.

For example, our AquaStop™ CrawlSeal™ vapor barrier is a powerful defense against moisture in your home, helping you create a drier and safer living space for your loved ones.

What Are Crawl Space Vapor Barriers?

A vapor barrier is a durable plastic liner that covers walls and uncovered dirt floors in your crawl space. It protects against excessive moisture and blocks water vapor from appearing in this area of your home.

The Basement Guys use the AquaStop™ CrawlSeal™ vapor barrier as part of our holistic crawl space encapsulation service.
