My house is now about 40 years old and the original Anderson Narroline windows are starting to fall apart. Several of the sashes are pulling apart at the corners and almost all of the sashes are getting soft on the outside and along the bottom. I am planning to install vinyl replacement windows and I’m looking for recommendations for what brand/model. Does anyone have experience with the American Craftsman 70 series sold at Home Depot or the Thermastar windows sold at Lowes? Or would it be best to go to a building supply place (like ABC) and get another brand? Thanks for the help!
