Hi have read the information but would be glad of any opinions.
My house is about 200years old, thick stone walls. Have ongoing problems with one small area of external wall in diningroom, damp patches and flaking paint mainly behind curtains. (Walls are paint on plaster)
This wall is very cold even when the heating is on, and the room opens into the kitchen on the opposite side of the room so is subject to some condensation from cooking.
Although I have been told by an expert I had in to look at it that the curtains have nothing to do with it is it likely that the condensation is worse behind the curtains because trapped there?
My plan is to replace curtains with blind, get a small dehumidifier ( any recommendations welcome) and redecorate!
Any comments welcome. also any suggestions about improving ventilation (sash window, painted shut.)
