Cyrnel might be on to something. I think there would be other signs if the moisture was coming from the walls, such as stains, bubbly wallpapers and such. How is the house ventilated? We throw open the windows for a few minutes once or twice a day during winter to change the air, it's a bit nippy for a while afterwards but since everything else is still warm the air heats up pretty fast.
The bathrooms and kitchen needs to be aired out well, after a shower a window should be opened to let the steam out, same after cooking something or doing the dishes.
How well insulated are the windows by the way? We have modern triple-glass ones, and get very little condensation on them since they don't get as cold as double- or single-glass windows.
So my advice is to reduce the amount of moisture in the air by strategic ventilation and make the cold spots less cold.
