Superior Service!!




Though it was not urgent, they were prompt, courteous, clean and explained everything clearly. Jorge Sema was so polite, and courteous and made sure no other issues before he left. I highly recommend Black Diamond!!

Electrical Job




They did a fantastic job. Highly recommend them!


Fast Response




We appreciate the consistent, fast response and the courtesy we can always expect from Black Diamond. The work is always done to a high standard and the site is left neat and clean. They are always are first call when there is a plumbing need.


Power outage




As per usual, the response was quick and the service succinct. Although the problem could not be resolved by Black Diamond, their serviceman was helpful in identifying the cause of the problem and directing me to ComEd.


Friendly, clear spoken repairman




Furnace was acting up. Frigid morning. Repairman arrived same day. Needed new control board. Gave me a discount since it was his second call on our furnace. Working great now!


Speedy service with a smile!




Rick completed our light fixture service quickly and efficiently today. The flickering is gone now - no more migraines! Thanks, Rick!

Prompt, Efficient Install




Prompt and quick installation of an exterior lighting project.


Great service and response.




At around noon or so on Super Bowl Sunday we discovered our sewer line was clogged, we called several companies to no avail then we call Black Diamond the phone was answered right away and they said James would be there within the hour. James showed up about 35 minutes later and proceeded to rod on the sewer pipe with the root cutters and got the drain unclogged just before our 20 or so guests arrived. Thank you very much.


Great service




Took care of replacing moen guts in shower fixture. I couldn't get it out myself. Very knowledgeable. Highly recommend Dave to do any plumbing work in the future.
