Hi,
For weeks we could smell something in the downstairs WC.
The builder kept saying that it was probably just that the extractor wasn't connected up.
Eventually though water started to leak into the WC along with drain flies appearing.
The leak has been fixed, but the flies are still there.
The leak was from an in wall cistern.
It seems that we have some water logging inside the wall and I now think it needs to be dismantled to get rid of the flies.
Has anyone ever seen screed get waterlogged however, noticeably the floor in the WC and the cupboard next to it are constantly way cold than the rest of the house, even in the current weather. I wonder if this is due to constant evaporation of water from somewhere. There is even now a small amount of moulding a corner.
As I say it looks like at the very least the wall needs to be dismantled but is there anything else we should be looking for before we put it back together?
Thanks
