How Much Does Window Replacement Cost in 2026?

Window replacement costs $450 to $1,200 per window installed in 2026, with a national average of about $750. A typical whole-house project of 10 to 15 windows runs $6,500 to $18,650. The price you pay depends on five things: the window type, the frame material, the glass package, your local labor rates, and whether you do a retrofit or full-frame installation.

This guide breaks down the cost every way that matters — by type, by material, by glass, by number of windows, and by location — so you can see where your project lands before you ever talk to a contractor. Every number here comes from the same data that powers our free calculator: U.S. Bureau of Labor Statistics glazier wages, FRED producer price indexes, and RSMeans labor standards.

Average Window Replacement Cost

Here is the quick answer for the most common ways homeowners ask the question. These are installed prices, including labor and a standard double-pane Low-E glass package.

Window Replacement Cost by Type

The style of window is the single biggest driver of price after material. Standard operating windows like single- and double-hung are the most affordable; specialty windows that involve structural work or multiple sashes cost far more.

For a deeper breakdown on the most common styles, see our dedicated guides: double-hung window cost, casement window cost, bay and bow window cost, and egress window cost.

Window Replacement Cost by Frame Material

Frame material affects both the upfront price and the lifespan of the window. Vinyl is the value leader; fiberglass and wood cost more but last longer and insulate better.

Vinyl accounts for the majority of replacement windows sold because it delivers good performance at the lowest price — see our vinyl window cost guide. If you are weighing the upgrade to fiberglass, our vinyl vs fiberglass comparison covers the trade-offs in detail.

Cost by Glass and Energy Package

The glass package is where energy efficiency lives. Moving from standard double-pane to Low-E with argon adds about 30 percent to the glass cost; triple-pane adds about 80 percent but pays back through lower energy bills in cold climates.

Energy-efficient glass also affects whether a window qualifies for utility rebates and ENERGY STAR certification. Our energy-efficient windows cost guide covers glass options, ENERGY STAR 7.0 requirements, and the status of the federal tax credit in 2026.

What Affects Window Replacement Cost

Beyond the window itself, five factors move the final number on your quote:

• Labor. Installation is typically 40 to 50 percent of the total. Rates follow local glazier wages and the complexity of the opening — see our window installation labor cost guide.
• Installation type. A retrofit (insert) window drops into the existing frame and costs less. A full-frame replacement removes the frame and trim down to the studs and costs more, but is necessary when the existing frame is rotted or out of square.
• Location. Labor and material costs vary widely by metro. The same window can cost 30 to 50 percent more in a high-cost-of-living area — see window cost by state, or see which metros are cheapest and priciest for installation in our 2026 Window Cost Index.
• Brand. Premium national brands cost more than value brands for comparable specs. Compare in our best replacement windows guide.
• Number of windows. Bulk projects lower the per-window price because the crew mobilizes once.

Cost by Number of Windows (Whole House)

Most homeowners replace 10 to 15 windows at once. Here is what a whole-house project costs by window count and frame material.

See our whole house window replacement cost guide and cost to replace windows by quantity for room-by-room and phased-project planning.

Is Window Replacement Worth the Cost?

New windows typically return 60 to 70 percent of their cost at resale and reduce heating and cooling bills, especially when upgrading from single-pane or failed double-pane units. The payback period depends on your climate, energy rates, and how long you stay in the home — our window replacement ROI guide runs the numbers.
