How Much Does Window Frame Replacement Cost? [2026 Data]

In 2026, the national average cost for window frame replacement is $392, based on 17,857 verified projects from Angi Pros. Most homeowners pay between $184 and $616 per window, with the spread driven by window size, frame material, and the extent of the damage.

How Much Does Window Frame Replacement Cost by Size?

Window size is one of the most significant factors in the cost of frame replacement, with prices reaching up to $1,200+ for a large bay window or an oversized picture window. A single professional can often handle a standard 4x3-foot window on their own. Larger windows require multiple pros, which increases both labor costs and the amount of frame material needed. 

The table below shows average window frame replacement costs by window size:

Window Pro Costs: Hourly Rates and Project Totals

Labor accounts for 70% to 90% of your total window frame replacement cost, averaging between $270 and $340 per window. Window specialists often charge $50 to $130 per hour, and a full frame replacement generally takes 2 to 3 hours. Minor repairs that don't require removing the window can cost as little as $50 in labor and take under an hour to complete.

Window Frame Replacement Cost by Location: Where Prices Vary Most

Because labor accounts for the majority of window frame replacement costs—just as it does for window cleaning—where you live has a significant effect on your total cost. Labor rates scale with local cost of living, so homeowners in high-cost states and major metropolitan areas will pay more than those in lower-cost regions. The table below shows average window frame replacement costs by state:

Window Frame Replacement Cost Factors: What Determines the Price?

Several additional factors can influence your final window frame replacement cost beyond size and labor. Understanding these variables helps you budget more accurately and avoid surprises once a pro is on-site. The sections below cover the most common cost factors to keep in mind.

Window Frame Material

The window frame material you choose affects your replacement cost, with options ranging widely in price, durability, and energy efficiency. Most homeowners replace the old frame with the same material to keep their windows looking consistent. The type of window frame you select will ultimately shape your upfront cost and your long-term maintenance needs. 

The table below breaks down average window frame replacement costs by material:

Type of Repair

Window frame repair costs range from $20 to $1,000, with labor driving the price based on job complexity. Minor surface fixes—like patching small holes or cracks—cost just $20 to $1,000, while major structural projects like dry rot repair or full frame replacements require complete window removal and reach up to $1,000.

The table below outlines average window frame repair costs by type of repair:

Window Accessibility

Window location directly affects replacement cost, with first-floor windows averaging $392 and harder-to-reach windows costing more. Skylights and second-floor windows can push your total up to $425 or more, since pros need extra time and equipment to safely access, remove, and reinstall the window. The added difficulty of working at height increases both labor time and the care required to avoid damaging surrounding siding or finishes.

Extent of the Damage

Simple repairs run closer to $184, but discovering window frame rot or significant water damage can push your total to $616 or higher. In severe cases, the window itself may need to be replaced—window replacement costs an average of $750 per window, which should be factored into your overall budget. The full extent of frame damage often isn't clear until a pro is on-site, so your final cost may be higher than your initial estimate. 

Number of Windows

Replacing a single window frame costs $392 on average, but your total cost rises when you're replacing frames on multiple windows. Most window specialists offer per-window discounts when you commit to more work, so your cost per frame goes down even as your overall total increases. The table below shows how per-frame costs shift with the number of windows replaced:

Window Style

Window style directly drives frame replacement costs—larger, more complex designs require additional materials and significantly more labor to install. A basement hopper window, for example, can cost as low as $60 for frame replacement. Bay windows, which are often 5 by 6 feet or 6 by 8 feet, require two or three laborers to remove and reinstall, driving costs up to $1,000 or more. The table below shows average window frame replacement costs by window style:

Permits

Permits for window frame replacement cost between $50 and $150, depending on your local building department, and are most commonly required for egress windows. Not every municipality requires a permit for this type of work, so check with your local building department or window specialist before assuming you need one. When a permit is required, your window repair specialist will typically include the cost in their project estimate.

Warranties

Some window companies include a labor warranty with their work, guaranteeing that the installation won't cause window damage or water intrusion. Specialists don't charge separately for warranties, but you can expect to pay 5% to 10% more for a pro who offers one. Since windows are your home's first line of defense against the elements, hiring a qualified professional is a worthwhile investment that helps protect you from costly water damage down the road.

Why You Should Hire a Window Frame Replacement Pro

Swapping out a window frame means dealing with factors like structural fit, exterior flashing, and insulation layers that all have to line up precisely. Even a small misalignment can cause drafts, water seepage, or a window that never opens smoothly again. Bringing in a local window frame specialist will ensure the opening is rebuilt correctly from the start.

Here's why it's ideal to hire a window frame replacement pro

A window expert knows how to rebuild the opening so the new frame performs the way it should:

• They verify that the surrounding wall is solid and free of hidden moisture and decay.

• Pros set the frame so it sits perfectly plumb and level, preventing future sticking and rattling.

• They install proper flashing and weather barriers that protect the wall from rain and wind.

• Their tools allow them to anchor the frame cleanly without damaging siding or interior finishes.

• They can walk you through frame options that improve energy efficiency and complement your home's architecture.

If you want to DIY a part of a bathroom design

You can handle a few simple prep steps yourself before the installer begins work:

• Take basic measurements so you can discuss the overall size and style you want.

• Move any nearby furniture and remove window treatments to clear the workspace.

• Think about whether you want to keep the existing trim or switch to a new profile.

• Learn the differences between frame materials to narrow your preferences.

• Note any issues the old window had, like drafts or condensation, so the pro can address them in the new setup.

Window Frame Replacement vs. Repair

Window frame replacement costs $392, on average, while window frame repair—which often doesn’t require removing the window to access the frame—costs an average of $200 per window and can total as little as $60. As such, a repair will almost always be a more affordable option than a replacement.

However, you should also consider the long-term cost implications. In most cases, if the window repair cost is 50% or more of the replacement cost, it makes more sense to pay more now for a full replacement. The new material will last longer than repairing the old material, so you’ll see more long-term value from a replacement than a repair.

How to Save Money on Window Frame Replacement

Window frame replacement can be an expensive project, sometimes costing up to $1,200. Fortunately, you can do a few things to save money in the process.

• Choose your frame material carefully. It's best for curb appeal to match your frame to the existing window and to your other windows. If you have an option, consider more affordable materials, like aluminum or vinyl, over fiberglass or composite. Alternatively, choose one that will require less window maintenance if you see a lot of extreme weather.

• Hire in the off-season. Window specialists are often busiest in the spring and fall. If your issue can wait, try to hire in the summer or winter, as you may get a discount during times of lower demand.

• Hire a professional for replacement. While you'll save around $300 on average tackling window frame repair yourself, it's worthwhile to hire a pro to ensure your window won't leak water or create drafts in your home down the road.

• Consider DIYing simple repairs. On the other hand, simple repairs like caulking around a frame, painting the window frame, or sealing a small crack are relatively easy to DIY. Consider doing the work yourself to save on labor costs. You can also DIY the disposal of the old frame to save on dumping costs. Consider donating it to a local charity organization or bringing it to the dump yourself.

• Get estimates from at least three experts. Finally, get estimates from a few professionals to compare based on cost and value. Take any warranties the companies offer into consideration, as well.

Does Window Frame Replacement Increase Home Value?

Window frame replacement can have an impact on curb appeal, which means the project can add to your home’s value. If your old frame is visibly damaged from the exterior, replacing it could grant a return on investment (ROI) of up to 80% of the total. If the damage isn’t visible from the exterior, you’re likely to see a more modest return, as low as 50%, provided you let a potential buyer know that you’ve had a professional complete the repair.
