Last night this random damp patch appeared on my kitchen wall.
We are in a first floor flat, there's one above, one below us.
The wall is a north facing wall, 1960s brick built, no insulation. Window is double glazed, but rubbish tbh.
There's no radiator in the kitchen. Wall feels pretty cold.
The damp patch is very inconveniently behind a kitchen cupboard, in a specific place.
The kitchen has been in place for about seven months.
There's a slight gap between the end of the cabinet and the wall.
The wall was replastered and painted a few months ago. This is the first time it's happened.
Measured it this morning and it's not gotten bigger.
After a year or refurbishment and the recent death of my best friend this is the last thing I need, esp before Christmas.
Any help or advice gratefully received, thank you.
