Carpenter came to change the bathroom door. Hes left the old door in the middle of my garden, quite literally and has left screws and bits of metal in the garden aswell. Ds loves being outside so finding these was a bit of a worry and i'm not sure if i have missed any. I have recently decorated it and he has scratched the doorframe quite a lot. To me this is poor workmanship and he should have thrown screws etc away and put the old door out of the way for safety reasons. Should i complain?
