I have a re-occuring problem each winter once the wet weather starts with wet and damp patches in the bedroom and also living room.
Since last winter i have removed the wallpaper and painted with damp proof pain once it had dried out. I have also purchased a de-humidifier and ensure a small window is open in all rooms at all times.
I woke this morning to find a damp patch in the top corner of the room and what i would describe as tears of water across the top of the outer wall beneath the coving.
Could this be a problem other than condensation?
