How Much Does Window Replacement Cost in 2026?

Updated September 2026 · Sourced from BLS, FRED & EIA

Window replacement costs $509 to $1,600 per window installed in 2026, with a national average of about $749. A typical whole-house project of 10 to 15 windows runs $5,090 to $24,000. 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 carpenter wages, FRED producer price indexes and NREL install-time benchmarks. For an estimate tuned to your zip code and window count, use the window replacement cost calculator below.

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.

Double-hung windows ($509 - $1,013)

Double-hung windows are the most popular residential style. Both sashes slide vertically, making them easy to clean. They work in almost every room and come in every frame material, and they hit the sweet spot between cost and function.

Casement windows ($405 - $1,044)

Casement windows crank open outward on a hinge, creating a wide opening that catches breezes. They seal tighter than sliding styles, which makes them one of the better choices for energy efficiency.

Bay windows ($2,162 - $5,832)

Bay windows project outward from the wall in three panels — a large centre picture window flanked by two operable side windows. The structural support drives the cost, and the calculator quotes them separately from standard units for that reason.

Egress windows ($3,046 - $7,669)

If you are finishing a basement bedroom, building codes require an egress window large enough for emergency escape. That means excavating outside the foundation, cutting a larger opening, installing a window well and waterproofing — excavation, the well and drainage are quoted separately by the contractor.

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.

Vinyl

Vinyl holds roughly 55% of the U.S. window market and is the lowest-cost frame for a quality product. Frames never need painting, resist moisture and insects, and insulate well. For most homeowners it is the value pick.

Fiberglass

Fiberglass is among the most durable frames available. It expands and contracts at nearly the same rate as glass, which reduces seal failures, and it insulates well. The longer lifespan and lower failure rate can make it the better long-term investment.

Wood

Wood delivers classic looks and excellent insulation — the go-to for historic homes and high-end builds. It demands real maintenance (periodic painting or staining) and is vulnerable to rot and insects. It is the most expensive standard frame option.

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. For rebates specifically, see which window rebates are still available by state, and for what the upgrade actually returns each year, see our estimated energy savings by state.

Low-E glass and gas fills

Low-E coating is a microscopically thin metallic layer that reflects infrared heat; it is standard on any quality double-pane unit and pays for itself through energy savings within a few years. Argon fill is denser than air and reduces heat transfer — standard in most quality double-pane windows. Krypton is denser still and is preferred for triple-pane. Double-pane with Low-E and argon meets or exceeds ENERGY STAR requirements for most climate zones.

What Affects Window Replacement Cost

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

• Labor. Installation is 17-32% of the total. Rates follow local carpenter 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.

Window Installation and Labor Costs

Labor is the part of the quote that follows your zip code — the calculator prices it from the BLS carpenter wage for your metro. See the full window installation labor cost guide for the wage tables.

Retrofit (insert) vs full-frame installation

Pocket (retrofit) installation fits the new window into the existing frame. It is faster, less expensive, and works when the frame is in good condition — but first, make sure replacement is the right call over repair. Full-frame installation removes everything down to the studs. It costs 40% to 67% more in labor but is necessary when frames are rotted or you are changing window sizes.

DIY vs professional installation

DIY saves $124 - $207 per standard window on labor, but most homeowners should hire professionals. Improper installation voids manufacturer warranties, can cause water damage, and reduces energy efficiency. Bay, egress and second-storey replacements should always be professionally installed.

Window Replacement Cost by Location

Labor rates, building codes, climate requirements and permit costs drive the regional spread — coastal Florida's hurricane-impact requirements and metro California's energy codes sit at the top, rural markets at the bottom. See detailed pricing for California, Texas, Florida, New York, Illinois, Pennsylvania, or browse all 50 states. The calculator above localises the whole estimate from your zip code.

Energy Savings and Tax Credits

Energy-efficient windows can cut heating and cooling costs by roughly 7% to 30%, with the biggest payoff when replacing single-pane units; the Department of Energy explains how window performance affects energy use. Savings alone rarely justify replacing windows that are in decent condition — the real value combines energy, comfort, noise, home value and curb appeal. Our energy savings by state page runs the numbers for your climate.

Window replacement tax credits in 2026

The federal Section 25C Energy Efficient Home Improvement Credit expired on December 31, 2025. If you installed windows before that date you can still claim it on your 2025 return (30% of material costs, up to $600) using IRS Form 5695. For 2026 installations, check state and utility rebates, which vary by location.

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. If you are not sure whether to replace yet, our guides on signs you need new windows and repair vs replace can help. To bring the cost down, see how to save money on window replacement.

How much value do new windows add?

According to the 2025 Cost vs. Value Report:

Vinyl delivers the higher ROI percentage even though wood adds slightly more absolute dollar value at resale.

When replacement makes financial sense

• Your windows are single-pane or have failed seals
• You feel drafts or notice condensation between panes
• Your energy bills are notably higher than your neighbours'
• You plan to sell within the next 5 years
• Your windows are 20+ years old

How to Save Money on Window Replacement

Timing

Timing the project right can save 10% to 20%: winter (Dec–Feb) has the lowest prices and motivated contractors; late fall brings end-of-year clearance; spring and summer are peak season with the highest prices and longest waits.

Getting good quotes

1. Get 3 to 5 quotes. Pricing varies widely between contractors.
2. Compare like for like. Each quote should name the same brand, model and glass package.
3. Never pay more than 20–30% upfront. A reasonable deposit is standard.
4. Ask about volume pricing. Ten or more windows gives you leverage.
5. Check credentials. Licence, insurance and references.

Budget-friendly choices

• Vinyl double-hung with double-pane Low-E is the value champion at $606 - $1,256 installed.
• Standard sizes over custom. Custom windows cost 25–50% more.
• Phase the work. Replace the worst-performing windows first.
