"I hired Prime Sine Electric LLC for a complete new electrical service and wiring on our 1937 home when purchased. It was in need of a complete gut-job. Spence did an amazing job bringing it up to today's standards. I mean, totally amazing transformation. Spence was professional the entire time through the quote process, customer service and final completion. He listened to our needs and gave input and helped us with planning the electrical needs of this old house. We can't recommend Spence enough and would hire him again in an instant."
