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!

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