- RMRob MorisSep 9, 20255.0After the severe hailstorm in April, Brian happened to be helping a neighbor with some immediate patchwork and offered to check out my house as well. He took over the conversations with both my insurance agency and the solar company to really help get get the house restored beyond what the insurance company originally proposed coverage on. The process for me was overall painless. He was great with communication, even responding after hours at times when I wasnt expecting a response until the next morning. Solid company to work with and looking to get a quote from them for some additional home improvement work.
