Had a backup on my main outlet at 7:00 PM on a Sunday – someone was at our house by 8:00 PM, and the problem was solved by 9:00 PM. Also appreciate the 1-year warranty on the service.

Steve

Rockford, IL

Excellent service. Came right out when my furnace went down, diagnosed the problem, and even left space heaters to keep my home warm while they ordered parts. Very friendly and professional. Excellent service!

Jim

Byron, IL

The service was exceptional, and the time it took to perform the repair was also exceptional. Kevin knew what he was doing, found the source of the problem quickly, and made the repair in under an hour.

Eric

Cherry Valley, IL

Sump pump failed. Called Black Diamond, and they had a repairman out within 2 hours. Luis was very professional, explained the problem and options clearly, and completed the agreed-upon work quickly and efficiently. I would highly recommend them to others.

Tim

Grayslake, IL

I needed a new water heater. Nick was knowledgeable of the product, efficient in its installation, courteous, and didn’t mind that I watched the process. He alerted me to a rusted supply line elbow, saving me a future leakage problem. This kind of service and attention to detail will keep me coming back to Black Diamond.

George

Johnsburg, IL

Had Black Diamond out to the house twice in one weekend; plumbing problem and then again for a ceiling fan install. Black Diamond employees are always courteous, neat, and go beyond. I also appreciate the fact that they warranty their work!
