Electrical Black Diamond is proud to be a sponsor of the Operation Click program. We have donated 9 cars to date, that are awarded to High School students that have pledged to drive safely and responsibly. Congratulations to our most recent winner, Yonni Gaglos of Elk Grove High School.
The service call was handled quickly, the service person was friendly and courteous and did awesome work!
The team came to install multiple electrical outlets in our house. This was no easy task as they were going in places which required going through and around studs. The guys did an excellent job of making recommendations, installation the outlets, then went above and beyond and hung the wall mounts and mounted the TV;s and hooked up all the gaming devices etc. I have used Black Diamond for many different electrical and plumbing needs, and they have always been top notch!!!
My wife and I are happy to continue our working relationship with Black Diamond. Our recent experience is a good example of promptness, ability, and personable service.
