The owner is easy to talk with and very personable. She really brought a lot of integrity and went out of her way to explain exactly what they were going to do and why. When I got the results of the auditing, she was able to really explain it in a way that I understood just what was going on with my house. She then provided me with solutions for dealing with it. They did both audit and insulation work for me. They get an A+ from me.
