Our house is single glazed and we get a lot of condensation, especiallyon our dormer window, which seems to be getting worse, I wipe it down every morning but it is starting to cause damp on one wall. Is this because of drying clothes on aires, although they are dried downstairs? I was going to get the double glazing film as I saw this mentioned on another thread, but not sure if it will solve the problem by itself? I think if we are going to carry on drying clothes on airers we need to get a dehumidifier, but I am becoming more and more tempted to just get a tumble dryer, as it would mean we didn't have to have airers put all the time. But that will be expensive to buy and they use a lot of electricity if using all the time in winter.
