Great Service!




Our water heater stopped working, and Jimmy was here quickly to look at it. New one was brought by another employee, and they both installed it in no time. We are very happy with Black Diamond.

Quick and easy!!




After calling three other electricians and having no luck getting someone to my house we called Black Diamond. They were here the next day and problem was solved within 45 minutes!! Great service! Friendly electrician who was very good at explaining what he was doing. Will definitely be calling Black Diamond in the future for any of our plumbing or electrical needs!!
