I highly recommend Rocky Mountain Spray Foam. We built a home in Fraser and Steffen Builders uses them for their new home builds. I am so glad that they did. The moment we met Joe Gould we liked him. Now our home is so tight it's actually warm in the winter with -20 degree temps. We barely hear the train from inside the home! I can't believe how sealed and tight the spray foam makes a home. We actually have to keep the heat turned down or the home is too hot. If you are building a new home call Joe Gould he's a top notch guy and his work is awesome. read more
