I have had an extension built and the builder has messed up pretty badly.
We may need to sue him for breach of contract ( he hasn't supplied and fitted 2 quite major things in the contract we signed. We have held money back from him because we need to pay someone else to do them. He also agreed that we could get someone else in to correct the shoddy workmanship
He is now saying that the he wants to come back and do the work, having agreed in writing that he didn't want to carry on as he wasn't able to complete the task. He was already 6 weeks over the deadline when he left and it took the new builder another week to finish ( but without the two major missing things)
We don't want him back as the standard of the other work is so bad. This for example is a window frame he put in.
