Sam has helped us with a few crises, and has always been incredibly reliable. We have always been satisfied with the work - he is serious, honest, and thinks carefully about what solution makes the most sense. This time, he completed the work ahead of schedule, and seems to have resolved a leak that 3 other people over the past 12 years have claimed to fix but never managed to get rid of. He's also timely and responsible to a stunning degree for the business. But my loyalty to him comes largely from the time this past winter when we had a little emergency, and I couldn't find any one else to help. Sam was off on vacation, but texted me several times a day with questions and advice, and arranged to come to my house the day after he got back from vacation; he was waiting in front of my house before I even got home from work. He's the first person I will turn to the next time I need anything done on our house.
