Hi
Some time ago I constructed a built in wardrobe in my son's house which has solid external walls. The wardrobe is in the northeast corner of the house in an alcove over the hall, where there is a radiator, and the stairs. Since it was built there has been a problem with what appears to be condensation running down the walls. He has extractor fans in the bathroom and kitchen and his tumble drier is vented outside. I have put ventilators into the floor/hall ceiling and high up in the wall between the wardrobe and the stairwell to allow some circulation of air but all to little or no effect. The house also has had double glazing fitted.
Can anyone suggest other steps that I could take to try to cure this problem?
Thanks
