Hammer the cut 2-by-4-inch boards into place around the opening of the crawl space using a regular hammer and concrete nails. Make sure the boards are set at least 1 inch back from the exterior edges of the opening so the plywood can fit into the opening.
How do I cover my crawl space outside?
Seal and isolate the crawl space from the outdoors and inside of the home by air sealing and adding a vapor barrier over the foundation walls and structural supports inside the crawl space. All cracks, holes, and penetrations leading inside the home or crawl space should be sealed with caulk or foam.Oct 25, 2021
How do you seal a crawl space entrance?
Seal any gaps you find using a quality, flexible caulk or expandable foam. In addition, install weather stripping around the crawl space entry door. If the floor down there is either soil or gravel, carpet it with thick plastic sheeting (to combat moisture problems).Mar 21, 2015
