Electrical Excellence

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!!!

Extremely prompt. Professional and fair priced.

We are hoping the circuit board will last longer than 3 years!! Can you offer a discount for services if we have multiple houses?

The Best!

I never use anyone else, their techs are pleasant, freindly, professional and know what they're doing. If you want them BEST, call Blk Diamond, (and no, I don't work for them!)
