This is the second time we have used Sprinkler Doctors and both experiences have been fantastic. They had trouble reaching me this time, but were very apologetic and made sure I was not inconveniences. Mark Dern, the technician was friendly, knowledgeable and listened to my concerns. He was honest about the issue, and took the time to explain the problem and answer my questions. They are very reasonable and I do not feel they are out only to make a $, but to help their customers. Thanks Mark and thanks Sprinkler Doctors!
