Long story short. Builder has done some works for us. Started off fine but then at the plastering stage took absolutely ages eg 2 half days of work in a 2 weeks period. This went on for a while. Also some other issues but the plastering was a crap job we've untidy finishes in every room. There's also some unfinished work but we were getting fed up with the builder not taking responsibility with stuff that has happened / denying things and we got rid of them. During this time he sent over an unqualified guy to paint an unfinished plastered room to keep us sweet which he threw in for free even though we disagreed. Work was shoddy as the lines are jagged where the 2 paint colours meet etc. So basically now have to buy and repaint the room ourselves inc filling and sanding. Before we did this we asked now much was outstanding. He told us and we paid. He then said we owe him money for the painting. Our last conversation was quite heated and we said we weren't paying and that's it.
It's all a bit of a mess but he's wanting to take us to small claims court which I have no idea what that involves.
Would be grateful for any useful advice and are we in the wrong - should we just pay it?
