Update:
Had them round today, went as expected really
As soon as he came in the plasterer mentioned the beading he'd joined and said he's sort it, I didn't realise he'd also done it on the other side. Then also mentioned a bit on the wall next to it saying he'd skim some marks out.
Apart from that they both couldn't see any other problems
I had to take them round and point them out even though the plasterer last night had drawn around them all in biro.
The basic feedback was 'you can't expect it to be perfectly flat, its not a machine finish' , 'its because you didn't have any skirting boards to work to' , 'your wiring was sticking out too far'
Basically told him its a bad job where he then got stroppy and said I might be better giving the job to the other guy. Told him I just want flat straight walls at the end of the day whoever does it.
He whinged a couple of times on the cost of materials to fix it, seemed to be more worried about his pocket than the walls.
Mentioned one of the worst bits of wall could do with the board replacing as its too far out. Its only 750x550mm, he pulled his face and said you're looking at £120 of board to sort it all out!! since when did a conservatory use 24 8x4 sheets of board?
They then asked for some more money towards the final cost due to the time its taking and they're out of pocket
Gonna have to make it 100% clear if its still not right after he's been again they aren't getting a bean till it is.
