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 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.
The efficiency case
Extreme climates are the one setting where premium glazing pays for itself over the years: triple-pane and gas-fill packages hold indoor temperatures steadier and trim the utility bill, with rebate eligibility a possible bonus on ENERGY STAR models. Between a better frame and better glass, the glass is where the payback lives.
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.
