Re-Lock Interlocking Stone

I hired Re-Lock to repair my stone patio and to replace a horrible lawn with new sod. The patio was releveled well, except for a small area that pools when it rains. The lawn was replaced, but I thought they would have removed the existing lawn, and put new soil and regrade and put new sod. However, they put the soil on top of the existing lawn, and then put sod on top of it. This has increased the level of the lawn to that of my neighbours so I'm not sure how this will work out. However, they do a good job of keeping the worksite clean and cleaned up well except for the three bags of heavy soil in garden bags. (Not thrilled about that).
