Nathan's performance was exceptional. He was prompt, professional, and knowledgeable, but what set him apart was his willingness to explain his findings in detail. I followed him around for hours as he patiently explained each issue we discovered. His report was so much more meaningful because I clearly understood each item, including why it was a problem and how to resolve it. Additionally, Nathan's sense of personal ownership was awesome. When we discovered a leak in the roof, Nathan spent a good hour crawling around in the attic and on the roof until he was confident that he understood the root cause (and solution) to the problem. I highly recommend Nathan and will definitely use him again.
