I have just got off of the phone with the plumber, he has has received my letter and wanted to discuss how we can move forward. He said he did not want things to get messy and was hoping we could sort things out amicably between us and reach an agreement that is fair.
I then explained that the cost of rectification is most likely going to cost around the same as his final invoice and then we have to buy more tiles as well so we are most definitely going to be out of pocket, I asked him what he thought was fair under those circumstances? After much discussion he has agreed to walk away with nothing and has said he will confirm this in writing as I said that I was not willing to have anything done to the bathroom by someone else until we have reached an agreement officially. I said I wanted to cover my back so that he cannot try and make a claim against me further down the line once the evidence is gone.
To be fair, he was very apologetic and said that he was really sorry for all the inconvenience he has caused. If I do get confirmation from him in writing that he is happy to walk away and "draw a line in the sand" as he put it, then I will consider myself extremely lucky on this occasion and ensure that I am more careful when choosing tradesmen in the future!! I really do hope he is not trying to pull a fast one somehow but surely if I have a letter from him saying he is happy to walk away without payment then that would stand up in court if he did ever try to chase payment from me?
