Window frame replacement cost
Window frame replacement costs $200 to $600 for standard-sized windows and $600 to $1,200 for oversized and custom-sized windows or more complex installations. The cost of replacing window frames includes removing and replacing the outer frame structure that anchors to the wall and supports the window.
| Project | Average cost per window |
Description |
|---|---|---|
| Standard replacement | $200 – $600 | For standard-sized windows |
| Oversized / custom | $600 – $1,200 | For large, custom, or complex installations |
A window frame replacement removes and replaces the outer structure that supports the window, including the head (top), sill (bottom), and jambs (sides), which hold the sash and glass in place. The replacement process involves the following steps:
Preparing the rough opening
Measuring the space
Removing sashes, trim, and liners
Checking for repairs
Adding insulation
Leveling
Sealing
Reinstalling trim
Finishing surfaces
Because each of these steps is time consuming, labor is a significant portion of the total cost.
Cost of replacing window frames by material
The material you use when you replace a window frame also impacts your overall cost. Vinyl is often the least expensive. Wood is one of the most expensive and requires the most upkeep. Composite and fiberglass both offer improved durability, energy efficiency, and low maintenance with a mid-range price.
The following table shows a cost comparison of frame replacement by material.
| Window material | Cost comparison | Description |
|---|---|---|
| Vinyl | $ | Cost-effective; energy efficient; low maintenance |
| Fiberglass | $$ | Highly durable; excellent insulation |
| Composite | $$$ | Durable; low maintenance |
| Wood | $$$$ | High-end; classic look; higher maintenance needs |
Full frame window replacement cost
A full-frame window replacement costs $700 to $2,000+ per window, depending on window size, materials, and the labor involved. This process removes the entire window, including the frame, and installs a brand-new window unit.
Window repair companies recommend full-frame replacement when the outer window frame attached to the wall is too damaged to repair, or when the existing sash and glass cannot be reused. If the frame is still structurally sound, less extensive (and less costly) repairs may be possible.
The table below shows alternative repair options for windows with intact frames.
| Repair | Average cost per window | Description |
|---|---|---|
| Full frame replacement | $700 – $2,000+ | Removes frame, sash, trim, and sill and installs a completely new window assembly |
| Insert window replacement cost | $450 – $1,500 | Installs a new window unit inside the existing frame; trim and casing remain intact |
| Window sash replacement cost | $200 – $600 | Swaps out just the sash panels or glass, keeping the original window frame untouched |
| Window frame repair cost | $150 – $600 | Fixes damaged or rotted parts of the window frame, leaving sashes and glass in place |
Window frame replacement cost factors
The main cost factors for window frame replacement are:
Labor: Labor makes up 70% to 90% of the total cost, as replacing frames is time intensive. Labor costs also rise with difficult installations, higher stories, or additional repairs needed.
Window size and type: Larger, custom-shaped, or specialty windows cost more to replace due to increased materials and labor.
Frame material: Vinyl is usually the least expensive, while wood, composite, and fiberglass cost more.
Condition of existing frame: If there is hidden damage, rot, or structural issues beyond the frame, the cost will increase because of needed repairs or extra preparation.
Location: Costs can vary by state and city due to differences in labor rates and building codes.
Additional features: Add-ons like custom finishes, energy-efficient options, or decorative trim can increase the final price.

Professional installation also ensures the work meets building codes and maintains warranty coverage.
