Improve your interior air quality by totally encapsulating your crawl space. You may do so by installing a moisture/vapor barrier on the walls and the floor totally sealing it off. You can do this with a minimum 6 mil poly or you can increase the mils and have it to serve as a Radon blocker with 16 mils or more. The product we use for the most part is equivalent of 20 mils.

Benefits of a Sealed Crawl

• Improves indoor air quality 
• More energy efficient 
• Floors are warmer in the winter 
• Could add additional usable storage 
• No more high humidity and condensation in the summer with the use of dehumidifier or conditioned air
