Electrical headache - solved




Had a vexing electrical issue with two outlets and a ceiling light. Matt came in, began assessing the situation and isolated the issue. He was prepared, methodical, and professional. Precisely what was needed to solve my issues. Matt from Black Diamond did a masterful job. Thank you!

Fast, efficient, courteous! Thanks!





Professional, courteous, and a pleasure to have worked with.





scheduling hassle.




Scheduling routine maintenance is difficult, and should not take 2-3 weeks to get done. Pre-pay for your services is a big (major) turn off for me. I do have confidence in the quality of your service and service people are great.

These guys are always prompt, knowledgeable, and thorough.

Panic Mode




I was in pure panic mode when I had an electrical issue at 5:30 am. Black Diamond to the rescue. The on call electrician lived miles away, but he responded as quickly as the traffic laws would allow. To top it off the electrician was pleasant and professional. There is no doubt in my mind I will be life time customer.
