They turned up without any materials and we had difficulty getting any. The fence has been put up in a bad way with short posts, and screws dangerously protruding through to next door. My old patio was not taken up as quoted, and new slabs were laid over the top. It is not level and slopes forward & sideways with a bump in the middle. Slabs are uneven, the built step has all broken away, as there is little support under it. And the grouting has gaps and different grouts used. Too many other probs to list.
