I have used them in the past and will continue to do so

Had Black Diamond out to the house twice in one weekend; plumbing problem and then again for a ceiling fan install. Black Diamond employees are always courteous, neat and go beyond. I also appreciate the fact that they warranty their work !

Awesome Service of course

Reviewing how great Black Diamond's service is, is almost boring. Yes, they were prompt, professional, polite, neat, and thorough. *yawn* What else is new? Seriously, they are great, and I call them for everything.

AC Repair

I called Black Diamond in the morning regarding my AC not working. They were able to schedule me in the same day. The technician, Nick, came out, quickly diagnosed the problem and fixed it on the spot. Extremely pleased with level of service from Black Diamond and Nick.

Another excellent job done well

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.
