I have a question. My husband was online almost a year ago and he found a great website that shows step by step how to fix old double hung windows. It showed what to do with the weights and how to replace the cords with a copper chain (I think) and a lot of other helpfull information. It showed lots of pictures and really explained things well. He started looking for it agian, and can't find it now. Does anyone know where we might be able to find a site like that again?? I would appreciate any help.
