Hi Eric! We have lived in our home for three years, and in those three years in the winter my windows accumulate water and ice. I clean them often but my windows are framed with wood and they have began to rot and mold grows throught the winter. Our windows are double glass to help the temperture inside the house. I had many suggestions and advise. Some say we need new furnace to even open the window in the winter slightly. Eric help please what should we do.
