Quality level
Window replacement cost is largely a function of how many windows you're replacing, their size and style, and whether it's a simple insert or a full-frame replacement. Energy-efficient triple-pane and specialty shapes cost more. This calculator estimates replacing a batch of windows on a typical home.
What drives window replacement cost
- Number of windows — the main driver, since windows are priced per unit installed
- Window style — standard double-hung is cheapest; bay, bow, casement, and custom shapes cost more
- Insert vs. full-frame replacement — full-frame means removing trim and siding and costs more
- Glass and energy package — double vs. triple pane, low-E coatings, and gas fills add cost
Window Replacement cost — frequently asked questions
How much does it cost to replace one window?
A single standard double-hung replacement window typically runs a few hundred to over a thousand dollars installed, depending on size and glass package. This calculator estimates a whole-home batch — set size to Small for just a few windows.
Are energy-efficient windows worth it?
Triple-pane, low-E, gas-filled windows cost more up front but cut heating and cooling bills and improve comfort, especially in extreme climates. They may also qualify for energy tax credits. Model them with the High-end quality setting.
What's the difference between insert and full-frame replacement?
Insert (pocket) replacement fits a new window into the existing frame — faster and cheaper. Full-frame replacement removes the entire frame down to the studs, which is needed if the frame is rotted and costs more. Full-frame sits at the higher end of this range.
