The definition of a Crawl Space:
A crawl space is an unoccupied, unfinished narrow space under a building, between the ground and first floor. The crawl space is so named because there is typically only enough room to crawl rather than stand; anything larger than about 1 to 1.5 metres (3 ft 3 in to 4 ft 11 in) would tend to be considered a basement. This is reprinted from Wikipedia.
Although Wikipedia explains that these are less likely to be found in the northern states, there are a lot that have been built in Southern Vermont. During our services we find many of them. They mostly do not have any vapor barrier and essentially the moisture from the ground (they often have a dirt floor) can gravitate upwards and increase moisture on the subfloor and possibly even into the home. This can eventually lead to mold on the subfloor and we have even seen it create mold throughout a home, especially if it has been shut up for a long period of time.
We have completed may jobs where this has happened and you can read about our mold remediation services on our mold remediation page.
Also we have removed the source of the moisture by installed vapor barriers. Visit our page about the vapor barriers we install.
