I contacted Tony (the owner) by e-mail on a Sunday to request an estimate on repairing the outlet in the back of my home that was no longer working. Tony contacted me back on the same day which happened to be a Sunday (which is outstanding in itself). After a couple of e-mail exchanges back and forth,Tony asked if he could call me so that we could further discuss what I was looking to have done. I also was intereseted in getting an outlet installed in the front of my house as well. He provided an estimate, and we made an appointment for the coming Saturday of that week. I explained that I had an appointment to get to later that afternoon, so the earlier he could get to me would be better. He said that he would call before coming to make sure the time still worked for me. On Saturday that is exactly what took place. Vinny one of Tony's workers called to see if it was still okay to come. I said yes , and Vinny along with Jason were at my house in no time. I showed them what needed to be done. They took the time to explain what they were going to do and how. Everything was done within an hour, and they left no trace that they were even there besides a working outlet and a new one. I also asked them about some additional work I might need and they took measurements and noted, so that Tony could provide an estimate for those jobs which he did. All in all, I can see why Diamond Electrical is highly rated on Angie's List. Excellent customer service! I will definitely use them again.
