I have a 1950's ranch style house that is in very, very good condition and I want to do some updating but since it was so well cared for I don't want to go overboard with renovations. I started updating in the back bedrooms and the windows are double hung Anderson, wood windows in what I would call "good" condition and I'm contemplating replacing them with better, higher end fiberglass/vinyl windows (wood is too expensive). So my question is: is this a good idea and would I get my money back when selling the house? I've had people say they like the old windows (they're not too drafty) and I'm not sure how much I would gain by adding new, white windows with updated white trim. I just wanted some ideas from people with a better eye for this stuff.
