@PenguindreamsofDraco I'm with you on the money point, he should absolutely have included that in his quote if it's needed to pass building control!
I am also hating it now. I am having glazed internal doors which I've sourced and my joiners are building a frame for them. I think I should have asked the builders joiners to do this as it's been a bit disjointed. Anyways the builder knocked the wall out, told the joiners he was going to "dot and dab" the walls either side of the opening but that would mean that the new walls stand proud of the original coving on either side of the opening. So i rang the builder and said no, I want it rough plastering then skimming and he basically said Oh I'll wait till you're back and bring Steve (plasterer) over. So another two days delay as I'm away till Wednesday. Any excuse not to bloody turn up.
