The breakdown is really helpful, thank you. From what I've read online, if you have underfloor heating you shouldn't have an additional layer of plywood anyway as it will reduce the efficiency of the heating.
@GasPanic Is it not just easier to get alternative quotes for it ?
I'm asking because if £5k sounds about right then it's a waste of time as I can't afford it. I also have to be home for the appointment.
Removing glued down flooring doesn't see like an easy job to me, either to do or to make sure the surface is in good shape for relaying afterwards.
I should have said in the OP, they wouldn't be removing any glued down flooring. It would just be ripping up carpet which was laid when the flats were built. Current LVT is in the kitchen which is fine.
It maybe if he has not seen your floor he has just included the plywood as a standard floor prep levelling charge.
He pulled back a corner of the carpet to check the subfloor and said it all looked fine, that he didn't anticipate any problems.
Also, is he doing stuff like beading or removing the skirting boards ?
He didn't say anything about skirting boards. He did talk about beading but only in response to me asking about click. He said he doesn't recommend click as it doesn't last as long and because you have to have the beading round the edges. I don't care about either of those things as I don't intend to stay here long term, and I think the beading looks fine.
There's moths in the building and my carpet has been destroyed over the years. I treat everywhere, hoover constantly, steam the carpets regularly, but after a few months they always end up coming back because neighbours have them. It's driven me to the brink of insanity. Pest control say there's no point treating as they're getting under the carpets, and even if it were effective they say they'll just find their way back in. They advised hard floors as the bastards can also eat synthetic carpet, especially when there's pet fur around.
