I have an old house with old windows that are covered in layers of paint, which I think is a good thing, because the wood has not been ruined. It is a historic house and the windows are worth saving. I have removed the paint, but I don't know where to buy replacement weatherstripping. Most of the windows have the metal strips and copper on the top windows and metal on the frames. Can anyone direct me to a source for weatherstripping in the Chicago area?
