Replaced our beat up casement windows (half of them didn’t open/ close properly and were starting to rot and some were drafty) with double hung. It’s so nice to have windows that work, look nice and keep the heat out in the summer and cold out in the winter. We didn’t like having to buy new windows for a house that was less than 12 years old (we had only been there for a few years) but it was some of the best money we ever spent!
