"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

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.

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!

Excellent, thorough, friendly

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!

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!
