Excellent Work




Jared and Matt showed up promptly as always, and did a remarkable job running a dedicated electrical line to my copier. They left no mess, and the work was done in an unobtrusive manner. They showed me what they did when they were done, explaining thoroughly so that I could understand it. Just like I have come to expect from everyone at Black Diamond, they were prompt, polite, professional, neat, and just a joy to work with. I can whole-heartedly endorse and recommend Black Diamond!

Outstanding Service!




Tony and Jared came over to do an estimate for some electrical work. They were scheduled to be here between ten and 2, and arrived promptly at 10:00. They spent two and a half hours thoroughly investigating the situation, asking questions and explaining their findings and the estimate. The estimate was explained in person, then carefully written out and explained again. While they were there, they saw that one of my storm windows was flapping free in the wind, scattering glass around. They screwed the window shut, picked up the glass, and refused payment, since that's not what they were called for. They explained every single item on the estimate, as to why it was necessary, what it did, and why it cost what it did. Most importantly to me personally, they are enthusiastic about their work and have great attitudes. I've said it once and I'll say it again, Black Diamond is the only company I will call for my electrical and plumbing needs!

Great Service




Marlon was awesome! Our basement drain was overflowing again so Black Diamond sent him over on a Sunday to check it out. He did a thorough inspection and went beyond what he needed to do to explain and show me everything going on. I know more about plumbing in my home now thanks to his expertise and explanations. His customer service skills are amazing and he had a great personality!

Fast,Experience and Knowledgeable




I've used plumbers from an home improvement store where they gave the profession a bad name. I've had the pleasure to work with Chris twice, Here and at my sons with the same fast service, quality work and willing to answer questions. Black Diamond must ensure the performance of there staff. Thank You Chris and Black Diamond
