By J. E.January 24, 2020Connect new gas range.
George provided excellent customer and technical service. I couldn’t have been more pleased with the outcome of his connecting my gas stove. He was attentive and listened to my questions-happily answering all them. I have told my friends about George and will be contracting him again soon for some additional work. He is definitely a find!
