This home owner in Windsor, CT had called us to come out to her home and check out her basement. One thing that we have to know when dealing with basements is that this area of the house is where a lot of air infiltration occurs. Due to the rim joist not being insulated or air sealed, she definitely had a problem. To fix this, our crew went down there and sprayed the rim joist with a 2-part expanding poly foam. This will seal up all the cracks and opening in the rim joist and help stop conduction loss by giving it some much needed insulation. Now this home owner will no long have to worry about her cold floors in the winter!
