James W. provided great service and expertise when my main breaker went bad. He shared useful information about the construction, function, and capacity of the breaker box. He was able to offer illustrative examples from his experience with other homeowners facing a similar issue to address my ""what if"" questions and other questions. He laid out the options available and the relative pricing clearly so I could understand and evaluate the trade offs to make a good decision in my situation. Then he went to work on installing the new breaker in an efficient and productive manner. He got the job done the same day faster than he estimated. The whole time he was courteous and positive in his attitude. It was a pleasant and reassuring experience in view of the circumstances. I found him to be trustworthy and reliable.
