Roger is extremely professional. However, he does not respond to telephone calls or emails in a timely fashion. Roger originally told us that he would be out on July 15th to take up sod and put down 3/4-1" rock. A week before, I called him to confirm and told him that I would be taking the day off so to be on sight during the work. I didn't hear from him until after July 15th, after I had taken the day off. He called a couple days later to schedule a start date the following week, which he missed by one day.He specified 3/4-1 inch rock for the yard. However, in a random review of 3 12x12 areas, there is more small (1/4-1/2 inch rock) than there is 3/4-1 inch rock. I called him about this issue. In his response, he said he contacted the place where he bought the rock and they said that some smaller stones would get into the mix. However, in this case, it appears that some larger stones got into the smaller stone mix.His polish does not match his delivery.
