Damp in upstairs external wall bedroom

Postby B-nightingale » Wed Jan 12, 2022 3:56 pm

Hi everyone hoping for some help . We moved into our new home and soon noticed damp in one room particularly. I’m somewhat stumped about why this room is damp. The room is at the front of the house and is exposed to the elements however the adjoining room which it was once part of has no damp at all (white room in photo). On moving in decorating we noticed most of the externals walls had been lined with a thick thermal lining(very hard to peel off the wall and impossible to cut). This is the case for this room also. The internal walls without the lining have no damp at all. I don’t know whether to blame the lining ?? We recently stripped it from the bedroom and added a lime plaster to replace and haven’t had any issues. The room does feel warm , as you can see from the photos there is a large radiator. We don’t dry washing in there , we don’t sleep in there. The living room below has no damp at all and also has the thermal lining. Windows are fairly new , we don’t get much condensation in there.

I’m wanting to redecorate and I’m just so stumped on what’s best to do.

The mould is unlike that we had in the other bedroom we have decorated. It is very faint an cloud like - not in defined spots. I’m wondering if this is because it’s coming from under the thermal lining. I have attached a picture of that from the other room we removed it from.

Appreciate any advice.

Hi b-nightingale,
Since the same front wall is damp in one room not the other and you have solid walls, have you looked at the gutters above the damp room to see if they are overflowing?
