Courteous, prompt and professional

Sewer problems are never a happy occasion, however, Dave K of Black Diamond worked very hard to diagnose and solve the issue. He was tidy, patient in his explanations and thorough.

Outstanding Service

From making the call for service to questions about whether we had anything else we needed done while he was there our experience was outstanding. And not for the usual big name service provider prices which was awesome. We will definitely keep using Black Diamond!!

Professional, personable technician

Keo arrived on time, cleaned my furnace and left the area totally clean when he was finished. He explained the options in the Crystal Club as well. Keo was very polite and easy to talk with. I'm very happy with the work he did!

Rick provides excellent service with clear explanations of issues, solution options, recommendations, and reasons for recommendations. He never seems to be rushing to finish to get to another appointment. We highly recommend him and Black Diamond.
