While the crawlspace probably does not look too much different than the before photos, the way that the CleanSpace was installed makes a world of difference. There are two ways that we seal the CleanSpace, one way is through a caulk/glue that adheres to the wall, and the second way is through a special tape that we use. They are both used during installation, and the tape is put at the top of the CleanSpace to keep the top sealed.
