I called Black diamond,about having my kitchen drain cleaned. Mario,was the plumbing technician who arrived on time. He looked over the situation,and got to work. He took great care in making sure my issue was resolved to the best of his abilities. I would highly recommend Black diamond,if all of their employees are as committed to excellent work,this is a company worth having a positive experience with.

Life savers! And I’m not even a customer. Well, I am now. I had a flat and without hesitation a representative from Black Diamond pulled over and hopped out with a battery operated compressor to help. It ended up being a pretty bad gash in the sidewall and wasn’t holding air. So he went back to the truck and got some rubber cement to help hold the air so I could get to a safer spot to change the tire. It was a busy two way street and he went above and beyond trying to help. And he did! Thank you so much. Praying I don’t having any plumbing issues, but if I do, I know who I’m calling.

I am so thankful for Black Diamond! They have single handedly helped me repair and maintain my home with ease and savings since 2019. Over the years, they have installed my furnace, air conditioner, replaced water shut off valves, garbage disposal, electric doorbell (Brennan was awesome), and most recently my water tank heater (Trevor and Keith were wonderful). I always get several quotes for big repairs and Black Diamond is always the best!! They are worth every penny. Honest up front pricing, no surprises, service windows are convenient, always on time, no employee turnover (i have had the same techs) and always knowledgeable and respectful. Their scheduling/customer service team is so kind and literally always answers my calls. Their quality is so good even my HVAC permit inspector raved about them when he came. It is a god send to have one company offer the best service in all areas, plumbing,HVAC, and electrical and with the most experienced technicians, best schedulers/customer service, and for the best prices. Thank you!

I’m a proud Diamond Member and officially part of the prestige family! My electrician was hands down the best — knowledgeable, patient, and professional from start to finish. I asked about 101 questions in under a minute, and he still managed to multitask, explain everything clearly, and get the job done right. He even fixed the light in my kitchen over the sink — someone before me thought it made more sense to put a plug there instead of an actual light switch and outlet combo (don’t ask 😅). But he got it working perfectly! Now I’ve got lights shining where there were no lights before! My utility room is beautifully lit with new canned lights — oh my God, excellent, très bien! As a single woman, finding honest, respectful professionals means everything. I felt comfortable, informed, and completely taken care of. Black Diamond is a true one-stop shop — they go the extra mile and make your home shine, literally and figuratively!

First off I like to share that my family and I are not familiar with well water as we come from Chicago. We are not familiar with how well water works and almost gotten taking for a hell of a ride but thanks to Colten and black diamond they have been a blessing for my family and I. we HIGHLY recommend them especially Colton. Very intelligent, understanding, respectful, honest person. I work from home and the staff respected that and worked around my schedule. Everyone from the customer service department to the staff that came to work on our house were very polite and kind to us. Thank you for everything you have done for us. May God bless you guys.
