Why exactly are you replacing all windows? Are the old ones rotting or broken, or just stuck? Do the old one not insulate well enough?
I used to make my living restoring windows on very old houses, both hung windows and ones that swung open or slide open. They can almost always be restored to function like new if they were of quality in the first place. A 1953 house would not be an old house in my world, however. I worked on pre-war stuff, back to the late 19th century.
Can you post some photos of the offending windows you plan on replacing? Sometimes replacement is a smart move, especially in extremely cold or hot locations where R-factor can be improved dramatically. Still, I've seen a lot of beautiful original windows ripped-out to install cheap, schitty vinyl or plastic windows from some warehouse in China. To me, it's like replacing the interior of an old 911 w something from Autozone because the seats needed to be rebuilt.
There are of course very high-quality replacement windows as well. Further info needed.
