Keeping moisture out of a Beaverdam, VA Crawl Space

All crawl space vents, the sill plate, and any penetrations to the outside through the foundation walls are all sealed. The rim band is insulated and sealed with spray foam insulation to stop air infiltration, which can also help with drafts in the first level of the home. The crawl space is also sealed off from the earth's moisture with a CleanSpace vapor barrier, which is sealed at all seams, wrapped and sealed around all piers, and attached and sealed to the foundation walls. All of these steps are taken to keep as much moisture out of the crawl space as possible so we can control the relative humidity and protect the substructure of the home.
