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.

Sealing Your Crawl Space...

• Controls Mold & Rot
• Save Money On Utilities
• Keeps Away Pest/Insects
• Passive Radon Mitigation
• Seals Away Odors
• Increased Comfort - No Drafty Floors
• Increases Home Value
• Additional Storage Space

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 CleanSpace® 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 SaniDry™ dehumidifier.

Before and After Installing Moisture Barrier

Moisture that enters the crawl space through vents and soil can ruin insulation and also encourage mold growth and wood rot.

Covering the crawl space floor and walls with a heavy-duty moisture barrier eliminates moisture problems, makes the living space more comfortable and cuts heating & cooling costs.
