Reply #36: I had estimates ranging from $4.5k-$12k for 12 windows

Local place was the cheapest. Sears and Home Depot 2-3x more. And this was essentially the same type of windows. I think ~$350-400/window is standard unless you are getting name brand (Pella, Anderson, etc.). My house is roughly the same age (1947 original windows).

The one thing that I remember looking for is that the window has a completely welded frame (not screwed), double pain, low e.

Check bbb and state licensing boards when you've narrowed down a contractor. And ask if they sub the work out (most places like Home Depot do).

Oh and check out the Home Improvement group here. Lot of knowledgeable people.
