I has multiple quotes for interlocks and decided to go with one of the cheapest ones which happened to be Park Hill Paving.
The jobs was a shoddy and poorly done with many amateur cuts and uneven stones , right at completion. They were paid in full , my mistake they were difficult to reach and once we did get hold of them, had agreed to come to remedy the issues but they never returned again.
Pay a higher rate elsewhere but not to this company. Today the work has to be redone.
