Doug came to add some circuits at my office and install floodlights for the parking lot. I cannot comment enough how great it is to work with Black Diamond. Every one that I have come into contact with is nice, enthusiastic about their job, knowledgeable, polite, on time, does great work and is clean. I just love the work they do, and can't recommend them highly enough. I have heard people say that they are pricey, but they are comparable to other quotes I have gotten, and worth every penny.
