Over a two month period my upstairs neighbour's boiler leaked and as a result my living room wall has mould growing on it and smells of damp. My bathroom which is adjacent has had a mushroom grow out of the ceiling but my council landlord has no interest in doing anything besides suggest 'airing' the place out which isn't realistic in winter. Waiting for it to dry out naturally could take 'months'. I got a dehumidifier in for a week and that seemed to make things much better but after it's removal the problem seems to be getting back to normal. If anyone has any ideas how to speed up this process, how to get rid of the mould or even let me know what the protocol should be then please let me know as I'm sure it isn't healthy to live in? All help is much appreciated.
