“Didn't know if I wanted to replace my stove with gas or electric. My original appliances were hardwired. Black Diamond 1st sent a plumber. Gas line was going to be too much work. Within 20 minutes had a Electrician at my house. I live in Marengo. Everything is a haul. ***** understood my need to have the work done asap. ***** had his schedule adjusted to do the job the same day. The work is excellent. The personality of ***** and *** the plumber were outstanding. I cant say enough of how grateful I am that I chose Black Diamond.“
