This Fayetteville, NY ranch retrofit resulted in big savings and comfort improvements for this homeowner. The project saved a lot this past winter and prevented the huge ice dams that many homes experienced. In this project Zerodraft’s skilled spray foam insulation crew foamed the drafty, chilly, crawlspace, which stopped the cold, damp air from cooling the floors above. We also air sealed the penetrations between floors and foamed the rim joists for maximum comfort and savings. We even insulated the basement outside Bilco door to help keep their home Zerodrafted!
