Great organization from the first phone contact through to the completed service call. The culture at Black Diamond is all about great customer service. Call center answered promptly,explained service call pricing upfront. I have used Black Diamond now twice once for plumbing and now for an electrical repair. What was the tell that this is a well run company is that both of my experiences were equally impressive. The technicians "Josh -plumbing" and "Gerad Electrical" were skilled,courteous and polite. It gave me piece of mind that these gentlemen were working on my home.
