The owners Shawn was so incredibly helpful & knowledgeable. He came to inspect our property the next day. We pulled our permits as "owner builder" which was a hard project, but got through it pretty well. However, I had trouble understanding what this report was all about. Shawn totally gave me the rundown on how it worked, sharing so much information with me so I was able to comprehend what was needed. We had a lil hiccup with our report, it required our plans to be modified, which he took the extra steps to help us overcome. After a long season of working with many tradesmen, handymen, other workers, inspectors, ect.... I'm grateful to have had Shawn see us over the finish line. He's great, and I recommend him to anyone who has a project requiring a HERS report. Thanks again Shawn!
