In the top corner of a currently unoccupied cold room, there is always a damp area in the top corner of the wall. I have run a dehumidifier in the room to try and reduce the damp spot, but it gets damper again. There are more spots underneath that are also damp. The bottom of the wall isn't damp.
The outside wall brickwork needs repair, however the damp area starts a bit higher than the poor brickwork, closer to where the tiles are and the white skirting.
I don't see any cracks in the tiles so I don't know if the water is somehow getting in under the tiles.
