A very impressive company. Daniel met us at our home within one day of our request for an estimate. He told us what the work would entail and answered all of our many questions. He was able to schedule the job within 10 days thereafter. He ALWAYS returned our phone calls before and during the job. We had met with two other paving companies and were unimpressed with both of them. Black Diamond crew and equipment arrived exactly when expected. Daniel texted us that morning to advise that he would be 10 minutes late. He arrived 10 minutes later. They prepped the existing driveway thoroughly and worked incessantly on two very hot days. Our driveway includes a basketball area, and a fork off to a pole barn. They had to remove several sections of the driveway that had deteriorated with age, then they built up those areas and lastly put down 1 1/2+ inches of asphalt over the entire 8,450 sq ft . It was a major undertaking and not inexpensive. We had never had to contract for asphalt paving before. It looks fantastic. It has enhanced our entire property.
