I was impressed by the way Gutterman, particularly Charles, addressed the repairs on my step-daughter's roof. The man knows his trade, and is not one to try to encourage repairs beyond what is needed. He found what needed to be done, and was clear about why and how he would make the repairs. He is very bright and well spoken, so there was no problem understanding the issues, and he was able to dumb them down for me. He also called me as requested prior to arriving so that I could meet him each time, and sent me texts of before-and-after photos. The day of the repairs, the temp was up to 100 degrees. I asked if I could bring him a drink, and he refused, saying, "We are professionals. We are prepared for this sort of thing". He also refused a tip. Lastly, it was clear to me that Charles is very loyal to Gutterman, which speaks to them as an employer, as well as to him. Although everyone I spoke to at Gutterman was efficient, it was Charles who makes Gutterman the kind of company who I will choose to do business with again.
