"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."

"Used this company previously and again it was a pleasure from beginning to end. I would give him 10 Stars if I could. Referred William to a close friend of mine and she was just as pleased. We both sleep better during our bad Florida thunderstorms. A friend of mine lost their home due to lightning. They got out just in time couldn’t save anything but their lives barely. I urge all to install lightning rods."
