The decking is sagging and moves every time you walk on it which we have to do to get out of the garden. The step also rocks when walked upon. The wood was left cracked in areas and there are some miss cuts. The concrete was undertaken during torrential rain and has resulted in constant dusting being trailed onto the decking and subsequently into the house. The concrete ran down the length of the driveway and cannot be removed. Phoned to complain 3 weeks ago and heard nothing further.

Shortly after finishing our renovation the floor began to lift, after a 2-year battle and almost court they admitted it was a fitting fault. Not ideal for a 12k job. Now our sink has fallen in, turns out he has used the world's smallest bit of wood and some sealant to fix it to the underside of our granite worktops rather than correctly fitting it using the fixings on the actual sink. Add to this, gaps between drawers and misaligned cupboards and you get the idea.
