Yep you are correct, he is stuck in his ways, been doing house building for 40 years blah blah blah! I think to keep the peace I will do the job correctly, only going to cost me some ply, primer and time. I will still earn out of the job, just not as much as I wanted, but as you say family and buisness do not mix. £xx per metre is the going rate for contractors down here in Devon. I quoted £xx and he nearly fell off his chair, this was the guide the course give us, saying that they are based in Harlow so prices differ to deepest darkest Devon, wish I was back in Herts sometimes..
Thanks for all your replys, you are an understanding bunch lol!
