No More Watery Mess !!!

My water heater must have been a lemon because within two years I had a watery mess in my basement!!! The water seemed to come out so quickly that practically the whole room in the basement was filled with water! A number of items got wet & I don’t know if they’ll be good anymore☹️ Nick Christiansen really knows what he’s doing because after inspection, he was quick at work, spending half the time another company with two men took. He was also very polite & courteous, offering to dry up the floor with some rags since I have a back issue. Couldn’t of asked nor gotten better service!!! Thank you Black Diamond for being so quick to get service for me & for sending me such a reliable & courteous worker!!! It was also wonderful to find out that you have other services as well. Since I have health issues, there are things I can no longer do by myself. You’ll be hearing from me soon & I ask only that you send Nick Christiansen, no one else because I finally have a reliable as well as courteous handyman!!! In gratitude, V. D.

Fast and Courteous Service

We had a partial power outage after normal hours and called the emergency line. We had an electrician, Dan, at our home in less than 20 minutes. Dan did a complete inspection and found the issue was not with our electric, but rather with the ComEd service. The peace of mind that we were given knowing the issues was not withy our homes’ Electric was invaluable. I so appreciate the quick and courteous service.

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.
