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 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.
The efficiency case
In extreme climates, triple-pane or premium low-E/gas-fill glass pays back in comfort and bills — and ENERGY STAR units may unlock rebates. Spend on the glass package before the frame upgrade.
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.
Buy the glass package your climate needs, default to vinyl frames unless you have a reason not to, and never let install quality be the thing you cut to hit a number.
