Derrick was exceptional. We called late Sunday afternoon because the main breaker kept tripping. This was not my first call, but I'm glad I called them anyway. Derrick diagnosed the problem within minutes finding a bad main breaker in the house panel. He was able to explain everything to my wife and me without talking down to us. Unfortunately, he couldn't fix it right away because parts were not available. However, he came out first thing Monday and had both the house breaker panel and the outside breaker panel changed out by 4 pm as well as the power back on. He also was able to install a whole-house surge protector. Not only that but he didn't leave a mess behind for us to clean up. Everything was returned to the way it was when he got here or better. Thanks, Mister Sparky.
