Window Replacement Cost Per Window in 2026

Window replacement cost per window in 2026 typically falls between $350 and $1,800 installed. The final price depends on the frame material, window style, glass package, and whether the project uses an insert or full-frame method. Because insert versus full-frame is decided only after the existing frame is inspected, these figures are planning estimates, not quotes.

How Window Replacement Is Priced

Window replacement is priced as separate line items: the unit, labor, removal of the old window, and trim work. A contractor will not finalize the installation method until the frame is inspected. If the wood is sound and square, an insert replacement can fit inside the existing frame. If the frame is rotted, water-damaged, or out of square, a full-frame replacement is required.

This separation matters because two windows with the same sticker price can have very different installed costs. Labor and removal vary by window height, accessibility, and whether interior or exterior trim must be replaced.

Cost by Installation Method

The two most common installation methods carry different price bands.

Insert replacement. The new window sash and frame fit inside the existing opening. This is less invasive and generally costs less.

• Vinyl double-hung insert: $350–$800 per window

Full-frame replacement. The entire existing frame is removed down to the rough opening, and a new unit is installed. This includes more labor and often new trim.

• Full-frame replacement: $550–$1,100 per window

Arithmetic example: if a vinyl double-hung unit costs $450, labor is $175, removal is $75, and trim is $100, the total installed cost is $800. If the same unit requires full-frame installation, labor might rise to $275 and removal to $125, pushing the total closer to $950–$1,050.

Cost by Frame Material

Frame material is one of the largest drivers of window replacement cost.

• Vinyl: $350–$800 for a standard double-hung insert; vinyl full-frame jobs often sit near the lower end of the full-frame band.
• Fiberglass: $600–$1,200 installed per window. Fiberglass is dimensionally stable and often painted, but the material and fabrication cost more than vinyl.
• Wood or composite: $900–$1,800 installed per window. Wood offers a traditional look but requires more maintenance and higher material cost. Composite blends wood fibers with polymer for reduced upkeep.

A homeowner replacing ten windows might compare materials like this:

• Ten vinyl double-hung inserts at $575 average: $5,750
• Ten fiberglass windows at $900 average: $9,000
• Ten wood or composite windows at $1,350 average: $13,500

These are estimates. Actual pricing requires an on-site measurement and frame inspection.

Cost by Window Style and Size

Standard sizes cost less than custom sizes. Common residential widths range from 24 to 48 inches, and heights from 36 to 72 inches. Larger or unusually shaped openings require custom units and additional labor.

• Bay or bow window: $1,500–$5,000. These units project from the wall, require structural support, and often involve roof or fascia work. A bay window typically has three panels; a bow window has four or more.
• Picture window: priced by glass area and frame material; fixed units cost less than operable windows of the same size because there is no hardware.
• Casement window: hinged at the side and cranks out; usually priced slightly above a comparable double-hung because of the operating mechanism.
• Sliding window: glides horizontally; often priced similarly to double-hung units of the same size.

Glass and Screen Replacement

Sometimes the frame is sound and only the glass needs attention.

• Glass pane or IGU replacement: $150–$450 per sash. An insulated glass unit consists of two or more panes sealed with a spacer. If the seal fails, the glass can fog and lose insulating value.
• Window screen replacement: $100–$350 per screen. Costs depend on mesh type, frame material, and whether the screen is standard or custom-sized.

Replacing glass only is viable when the frame is in good condition and the problem is limited to the glazing. If the frame is deteriorating, full-window replacement is usually the better long-term value.

Specialty Windows

Some window types carry higher costs because of size, weight, glass requirements, or installation complexity.

• Bay or bow window: $1,500–$5,000. The wide range reflects projection depth, number of panels, and whether new roofing or structural framing is needed.
• Impact or hurricane window: $1,200–$2,600. These windows use laminated glass and reinforced frames to meet wind-borne debris standards in coastal regions. They also require specific fastening and flashing details.

Labor, Removal, and Trim

Labor is not included in the unit price. Typical labor adds roughly $100–$300 per window, depending on:

• Window height and whether a ladder or lift is required
• Accessibility of the opening
• Condition of the existing frame
• Number of windows being installed in one visit

Removal of the old window usually costs $50–$150 per window. Trim replacement, including interior casing or exterior brick molding, can add another $75–$200 per opening.

Example calculation for a full-frame vinyl replacement:

• Unit: $600
• Labor: $225
• Removal: $100
• Trim: $125
• Total: $1,050

This arithmetic shows why comparing unit prices alone can be misleading. A lower-priced unit with high labor and trim needs may cost about the same as a higher-priced unit with minimal site work.

Energy Efficiency and Long-Term Cost

Efficient windows can reduce heating and cooling loads, but savings depend on climate, existing window performance, and local energy rates. Look for ENERGY STAR® certification and NFRC-rated U-factor and solar heat gain coefficient when comparing glass packages.

Lower U-factor means better insulating performance. Lower solar heat gain coefficient means less heat enters from sunlight. In cooling-dominated climates, a low solar heat gain coefficient may reduce air conditioning load. In heating-dominated climates, a lower U-factor helps retain indoor heat.

These are performance characteristics, not guarantees of specific dollar savings. Actual energy savings vary by home and usage.

What to Expect From an Estimate

A legitimate estimate should list the unit, labor, removal, and trim separately. It should also state whether the proposal is for insert or full-frame installation, subject to frame inspection. Avoid any document that presents a planning band as a firm quote.
