I live in a 1960?s semi and we have always had loads of condensation o
the windows, worst in the winter. We replaced the old aluminiu windows / doors with UPVC and while this has improved slightly we stil get misted up with puddles on the sills. Therefore, there must b another cause. We have a de-humidifier that reduces some of th condensation but it can only be in one room at a time.
Any ideas what could be causing this and how we can resolve it? Coul it be anything to do with the damp proof course?
Thanks
