Producing The Perfect Crawlspace

Seal crawlspaces with a vapor obstacle along the floor as well as walls that goes to least 6-mil or much more. This will prevent wetness from getting in the home, termites from getting to lumber and also  dirt gases from leaching into the floor covering system. Attach the vapor obstacle mechanically at the 
edges as well as secure all seams joints with tape.  http://www.agreatertown.com/charleston_sc/charleston_crawl_space_pros_0001462539
