The price of a replacement window depends mostly on frame material, style, size, glass package, brand and installation type. Standard-size vinyl windows sit at the low end; large, custom, wood or fiberglass windows from premium brands cost several times more.

What affects the price
- Material: aluminum and vinyl are cheapest; wood and fiberglass cost the most (see vinyl, fiberglass, wood).
- Style: single-hung and fixed windows cost less than casements, bays and bows.
- Insert vs full-frame: a full-frame replacement (new frame to the studs) costs more but fixes rot and air leaks around the frame.
- Glass: double-pane low-E is standard; triple-pane adds about 15% (This Old House averages: $529 vs $609).
- Brand and installer: national full-service brands with in-house installers usually quote the most.

- Choose standard sizes where you can; custom sizes cost more.
- Ask about off-season pricing (late fall and winter).
