We have had a floor sanding man come to our house to sand and put an oil varnish on the floor. However, he left yesterday and on closer inspection the floor has specks of black fibres in it (I saw a black type rag he was using when I went to check on him). I also had to leave him whilst I had to go out with my children when he was finishing his job. When I got home we noticed a hole in our wall (only small) and some of his oil or varnish dripped down one of our doors - I’m not happy and we’ve only just realised this. He also helped himself to drink from our fridge without asking! I’m due to pay him £200 after paying him £500 initially for the works. I’m not sure how best to proceed but at the moment I am not happy with the finished works along with the damage he has caused to our property although only minor, I’m still irritated by his clear dishonesty. What would you do?
