The CrawlSeal® Crawl Space Vapor Barrier System

Seal the vents and install a liner to preserve & improve your crawl space

What It Does:

The CrawlSeal® Crawl Space Vapor Barrier is the heart and soul of the CrawlSeal® system. This durable, bright white crawl space liner installs on the walls and floors, preventing water vapor and humidity from passing through. By keeping your crawl space dry, you protect your structure and insulation from mold and rot.

With a 25-year warranty against rips and tears, this durable 20-mil poly-reinforced crawl space liner converts your crawl space into a usable storage area. And with its mold-resistant additive “UltraFresh”, CrawlSeal® will never support mildew or mold growth on its surface.

Installation Time:

The CrawlSeal® Crawl Space Vapor Barrier installs quickly in your home, attaching to the walls with plastic pegs. Typical jobs take less than a day.

Benefits of Crawl Space Encapsulation

Installing a crawl space vapor barrier is one of the most cost-effective ways to improve your home and prevent the need for future crawl space repairs.
Along with protection from mold and rot, a dry crawl space will also be inhospitable to termites, cockroaches, ants, crickets, and many other pests that need excess moisture to survive.

Mice and rats are deterred by the plastic vapor barrier, and flooding waters will be kept at bay.

By sealing a crawl space, you also keep away odors and allergenic mold spores that would otherwise rise up through the floor and into your home due to the stack effect.

By sealing your crawl space, you keep the summer heat out of your home and the winter cold away from your furnace, water heater, and other utilities.

As an additional benefit, the CrawlSeal® crawl space vapor barrier acts as a passive radon mitigation system. It is also compatible with your active radon mitigation system as well as products such as crawl space sump pumps and the Tar Heel dehumidifier.
