How much should new windows really cost you?
Windows are priced by frame, glass and install method — and homeowners often spend on the wrong one. Our editors on what's worth paying for.
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.
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.
Spend where it counts — the glass package for your climate — and don't default to a premium frame material without a reason. Whatever you do, don't cut install quality to hit a budget number.
