How much should new windows really cost you?
Frame material, glass package and install type decide the price. Our editors on what's worth paying for.
The efficiency case
Where winters bite or summers punish, upgrading the glazing — triple-pane or a gas-filled low-E package — returns real money on heating and cooling bills, and ENERGY STAR-rated units can open the door to rebates. Put that upgrade money into the glass before you spend it on a fancier frame.
The install case
A perfect window installed badly leaks and fails. Full-frame replacement with proper flashing beats a cheap pocket insert in a rotted opening — match the install method to your home's condition, not just the price.
The value case
Vinyl, double-pane, low-E windows deliver most of the comfort and efficiency for the lowest price. For whole-home replacements on a budget, they're the sensible default.
Windows reward homeowners who spend deliberately: glass tuned to the climate, a vinyl frame by default, and an installer who won't skip flashing. Trim the frame line before you touch either of the other two.
