As home inspectors we know that moisture coming up from a dirt crawl space into the sub floor of an average home can carry with it gallons of moisture. Moisture that will be deposited on the sills, joists, main beams and sub floor.
On a recent inspection in Hamilton NJ I saw a vapor barrier that was a bit unusual. It did not stop at the crawls edge. It went up the side of the foundation and was attached to the sill plate.
This barrier will keep moisture from building on the sub floor expressed as mold, rot, white rot and cubicle rot. If the conditions are not reversed the damage can mount to the thousands.
This is a picture of a vapor barrier the way it should be installed.
