a house which was empty for nearly 2 years now went in to discover upstairs in one bedroom, 1 whole wall is mouldy and wet. I peeled the wallpaper off,and inside is wet and mortar keeps falling off to the touch.
mould is green
in colour and black.
its an end terrace 2 beds.
the wall which is affected badly located to the end of the house so could it be the poitning from outside, i looked it seems fine.
and other bedroom is wet just slightly from ceiling to the wall same on the stairs ceiling to the wall not bad at all and no mould there just wet patch.
no issues downstairs at all no sign of water or damp\mould.
i tried to share some photo as it would have been very useful to illustrate what i am talking about however it keeps saying image failed.
any help i would really appreciate it, i will get someone to have a look at it but i just need to have an idea of what it might be.
thank you in advance
