Fast, Professional, Friendly

We are very pleased with our service today! I called at 5pm yesterday to report our clogged drain. I was connected directly with a human (no voicemail run around) who said they could send someone out in a few hours with an after hours service fee, or at 8am the next morning at standard pricing. Since we didn't have an active leak, I decided we could live until the next morning without the kitchen and opted for 8am. Dave showed up on time, got right to work, had all necessary parts and equipment on hand, was extremely clean and professional, and he had us up and running by 10:30am. We will absolutely use Black Diamond again in the future and highly recommend them!
