Having made the decision to install solar panels in our backyard, we entered into a contract with Rick Milburn of PassivWorks. Rick had explained to our satisfaction the benefits of solar energy and what the expected savings would be in our case.

Rick Milburn and his PassivWorks crew built a new home in the Passive House Standard for my wife Jennifer and I, which was completed in 2012. Rick has been a great pleasure to work with. Everything Rick did in building our home was done thoroughly and thoughtfully. His work is exacting and of great quality. If I were to build again in the future, I would work with no other builder than Rick.
