DIY DONNY

toilet flooded in my son’s new en suite and there are now discoloured patches. We think pink mould is coming through the vinyl from the moisture. After removing the vinyl should we remove the plywood put down to lay the vinyl. Or do we treat with a spray? vegetation and scrape moss off. Then, run a strip/line of flat copper over the ridge of the roof – copper is supposed to prevent moss forming. I must say I have never tried this myself but I’ve heard good results.

HAVE small patches of blue fungus type marks on my living room wall. We had artex for years so we put plasterboard over it, then skimmed and painted. I’m thinking damp could be down to moisture between the artex and plasterboard. What do you think?
