VFI did a great job at my house. We had an old drafty stone-walled basement – full height and crawlspaces. VFI covered the dirt-floored crawlspaces with a heavy-duty plastic we had found & foamed the basement walls from the sills down to the plastic vapor barrier. Made a huge difference. Where they foamed the stone walls – that solved a long-standing water penetration issue, and even brightened up the basement. Customer service was great. The crew was very professional and left the place clean as a whistle. I highly recommend VFI.
