"Diamonds" are forever.

We think Keo was exceptional. He was very fast and efficient and reviewed all the necessary details. Also, he was a very nice man to have for a service call.

Excellent Experience

Tom from Oakwood Hills, IL

Daniel was friendly, knowledgeable, and established a positive rapport. His work was efficient and completed in a professional manner. It is evident Daniel is an expert on his field. In addition, he clearly explained everything he needed to do and went above and beyond to service our needs. I have given an awful rating for the pricing of the work done today as the total we paid today was $1000 more than communicated to us by the person who gave us the estimate.

Gerald is a great person. Very patient and answers all questions..

Great price and even better service!

Dave K did a fantastic job fixing our plumbing issues in our laundry room and bathroom. The work was done quickly and cleanly. He fixed the problem and it’s now better than it has been since we’ve bought our house three years ago!

great service

Beth from Oakwood Hills, IL

Jesus came today to work on some plumbing problems that have been an issue for a while. He solved everything quickly and professionally. Absolutely meticulous and perfect after job clean up. GREAT work.

Everything went smooth

We were happy with the installation of our ceiling fan.

Excellent, thorough, friendly

Dale from Oakwood Hills, IL

Very personable rep, and knew his business. On another issue, a "confirmation" call was made to our home on Sunday morning, REQUESTING a call back for confirmation. I find this intrusive and inconvenient. Try switching this to an online return. Much more convenient. The Drs dentists do this. Why can't you? Dale Dungan

Thank You!

Kate from Oakwood Hills, IL

I made the call at 8:30 on Saturday morning and had a technician arrive at 9:30. Amazing customer service, extremely knowledgeable and professional technician, repair was completed quickly and at a reasonable price. I highly recommend Black Diamond and becoming a member of the Crystal Club!

Worked with us on what time worked well to complete the job.

We've grown accustomed to having excellent service from Black Diamond and I have to say today's visit did not disappoint. It's really great to know someone likable and professional is going to be coming to my home.

Mike's here - Gather 'Round

Lyon and Fran from Oakwood Hills, IL

We've had Mike at our house twice now. Mike is forever nice, very caring and sympathetic and also very informative. The interesting thing about Mike's visits is the timing. First visit: entirely new furnace system and duct cleaning; Second visit: entirely new AC system. He makes us love Black Diamond!

Great service and results.

Susan from Oakwood Hills, IL

Doug did a great job! He was very polite and cleaned up when he was done. I am very happy with the results!
