Electric panel freak out

Showing up early and upon helping out with trying to trouble shoot an problem, we learned that our Electrical main had some serious issues including 27 recalled breakers and illegal grounding lines. So we moved forward with replacing the whole thing. The hard part was shutting down the house for close to 5 hours. But it went perfect. Thank you.

Great Service

Black Diamond calls ahead and gives the name of the tech. Keo arrived within the first 10 minutes of my scheduled appointment even though the weather was bad. He used covers for his shoes. He was polite and explained about a worn part that needed replacing. Great Service as always.
