Mike Diamond looks like they're very interested in satisfying their customers. About a month ago, I had to replace a sewage backflow gate because another plumber had broken it. I had initially spoken to their tech and was going to do it myself. I got straight advice from him and that was it. I had only called him after a few days because I had such a hard time finding a part myself. They gladly came by and put it a good day's work. Both tech's were very professional and friendly.
Pros: Friendly. Good guys.
