You'll pay about $815 for the cost of casement windows, or anywhere from $260 to $950 depending on its size, frame material, and installation cost.
Casement windows cost an average of $815 and range from around $260 to $950. Larger windows or energy-efficient options will fall on the higher end of the cost range, and homeowners should factor in costs for professional installation, prep work, and the specific type of casement window before starting this project.
Casement window costs depend on a number of different factors, from the size of the window to the type of material the frame is made from. You’ll also need to consider installation costs, plus the fees for any prep work necessary to get the wall prepared for a window replacement.
Casement windows range from about $260 for a standard 24-inch-by-36-inch window to around $630 for a larger window of 36 by 60 inches. The larger size of the window, the more it will cost for materials and installation.
Some common casement window sizes and their costs include:
| Window Size (Inches) | Cost |
|---|---|
| 24 x 36 | $260–$360 |
| 24 x 48 | $350–$515 |
| 24 x 60 | $420–$450 |
| 30 x 36 | $275–$400 |
| 30 x 38 | $215–$470 |
| 30 x 60 | $460–$480 |
| 36 x 60 | $335–$630 |
When you prepare to buy any type of window, you’ll need to decide which material is right for your home and your budget. Casement window frames can range from around $200 for standard vinyl windows to over $2,000 for customized wood casement windows—and that’s just for the cost of materials.
You may opt for single, double, or even triple-pane windows. The more panes, the more energy-efficient and insulating the windows will be. Typically, double-pane windows cost about $150 more than single-pane windows and triple-pane windows cost about $250 to $550 more.
Single-pane casement windows: $150–$400
Double-pane casement windows: $150–$600
Triple-pane casement windows: $400–$950
Highly efficient casement windows cost a bit more on average than those without these special features. Energy-efficient window prices often factor in:
Double- or triple-pane windows
Low-E windows or insulated glass
Argon or krypton-filled windows
Fiberglass window frames
Casement windows with any of these features push the price to $200 to $950 per window. Keep in mind, however, that some window designs will qualify you for an energy-efficient tax credit.
Once you get casement windows on your radar, you'll start spotting them everywhere and in various designs. Casement windows can adapt to many wall and ceiling sizes, making them ideal for oddly shaped skylights or sidelights and flanker windows that sit beside doors. Here are some popular types and casement window costs below.
| Type of Casement Window | Cost Range |
|---|---|
| Single casement | $200–$450 |
| Double (French) casement | $450–$950 |
| Push-out casement | $350–$950 |
| Top-hinged casement | $150–$1,000 |
| Cottage-style casement | $150–$1,000 |
| Flanker casement | $600–$1,100 |
| Egress casement | $600–$2,300 |
Hiring a professional window installer will add about $100 to $300 per window to the casement windows cost. If you need to remove an old, existing window to make way for the new casement window, you’ll spend about $60 more per window. The pros can remove the older windows and properly dispose of them for you for the added cost.
You may have some extra prep work to handle before you can install the casement window. Maybe you’re adding a window into a wall that doesn’t have a window already, or you’re planning to replace a small picture window with a much bigger casement window for more light in the living room. Enlarging a window costs $800 to $5,000, while putting in a new opening in a wall can cost an additional $1,000 to $5,000.
A window is much more than just its glass. The type of window frame is a detail that significantly affects the cost of a casement window. The frame can provide more insulation, and some materials will better withstand harsh weather conditions than others. Not only that, but with casement window costs ranging from $200 to over $2,000 based on the material, it’s an important factor to consider when budgeting.
| Material | Cost (Material Only) |
|---|---|
| Wood | $260–$2,000 |
| Vinyl | $200–$780 |
| Aluminum | $200–$1,180 |
| Fiberglass | $535–$1,575 |
| Composite | $350–$1,450 |
Wood casement windows cost $260 to $2,000, with prices depending on the size, panes, and any other customizations. Wood is a popular frame material because it looks great and is pretty strong. But this material requires a lot of maintenance, usually painting or resealing the frame every few years to protect against moisture.
Vinyl casement windows, which cost $200 to $780, are popular for their durability and budget-friendly costs. Vinyl is easy to clean and requires very little maintenance. The downside to vinyl is that this material may warp or crack when exposed to extreme temperatures.
Aluminum casement windows cost $200 to $1,180. These windows are lightweight and easy to install, plus they add a sleek, modern look to any home. But aluminum is vulnerable to corrosion and isn’t great for insulating, so it works best for homes in mild climates.
For the durability and longevity of fiberglass, you’ll spend $535 to $1,575 per window for materials. This material is popular because it comes in a wide variety of colors and styles. There are even fiberglass frames designed to look like wood. Fiberglass is one of the most expensive window frame options.
Composite casement windows cost $350 to $1,450. Like fiberglass, composite windows are durable, easy to maintain, and come in a variety of appearances. Manufacturers can even design composite windows to look like metal or stone. The drawback to this type of window is that they are another more expensive option.
Installing new windows can come with a variety of factors to consider to stick to a budget. You may need to pay for permits before you start enlarging a window opening to fit the new casement window, or you may want to keep in mind the ongoing costs to paint or seal wood window frames over the years.
Window repair costs range from $175 and $610. Because casement windows have so many moving parts, they may require more frequent repairs than a picture window or double-hung window. You may need to replace the hardware for $75 to $200 or fix the seals for $200 to $600.
Any windows, casement windows included, need regular maintenance. This mostly means keeping the tracks, seals, and glass clean. Window cleaning costs about $150 to $300 total, or about $4 to $15 per window. You should deep clean your windows at least twice per year.
However, wood casement windows need more TLC. You could spend about $50 to $110 in materials and tools to repaint or seal wood window frames. Repaint or seal window frames every five years or so to protect the wood against moisture.
Building permits cost about $50 for windows. You may not require a building permit for your project if you’re simply replacing an existing window with a new casement window. But if you need to create a new opening or enlarge an existing opening to fit the new window, you’ll likely need to obtain permits before starting construction.
Installing casement windows yourself costs about $200 to $2,000 for just the window materials. You may also need to spend money on the following tools and supplies:
Power drill: $20–$150
Pry bar: $5–$50
Putty knife: $5–$10
Screwdriver: $5–$20
Hammer: $5–$25
Safety gear, including goggles and work boots: $20–$250
Ladder: $150–$500
Caulk gun: $5–$25
If you just need to replace casement window glass or a screen, this can be an easy to intermediate DIY project. However, if you’re installing a full-frame window, enlarging an existing window, or demoing a wall for a new window opening, you should hire a window replacement specialist to securely install your new casement windows.
Unless you have extensive construction experience and all of the necessary tools in your toolbox, casement window installation is best left to a local window contractor. Window installation could involve rerouting electrical wires, repairing drywall and/or roofing, or fixing siding, in addition to handling a heavy window.
Not only that, but if the window doesn’t slot into place correctly, it won’t insulate your home against extreme temperatures and rain. Any moisture that leaks into improperly installed windows can lead to mold and costly water damage.
While you are installing new casement windows, you may dream of adding remote-control blinds or a UV-blocking window film for more energy-efficient windows. Here are some costs for common add-ons you may consider for your casement windows:
Energy-efficient windows cost: $120–$1,200
Window treatments cost: $150–$1,650
Blinds or shades cost: $200–$1,350
Window cleaning cost: $150–$300
Window seat cost: $500–$8,000
Casement windows are a worthwhile investment to your home. They add a charming look, and they are easy to pop open for a breath of fresh air. However, if you’re looking to cut down your budget, there are some ways to save money on casement window costs.
Shop in winter: Look for off-season deals by shopping for windows in the winter. Wintertime installations may also score you a deal.
Bundle with more windows: You can typically save money when installing multiple windows at once over a one-off.
Go standard: Choose standard colors and sizes whenever possible, as custom casement windows can cost into the thousands.
DIY when you can: If you can remove the old window and dispose of it yourself, you could save a little cash.
Keep up with maintenance: By keeping your windows in good condition, you can save on repairs in the long term.

Casement windows are more expensive than some other window types, such as single-hung or double-hung windows. However, casement windows are not the most expensive type of window. Bow and bay window costs tend to be the highest, because they involve multiple large windows that jut out from the exterior of the home.
Casement windows are safer against intruders than double-hung windows, because they are extremely difficult to pry open from the outside. However, if you’re concerned about young kids or pets, double-hung windows have safety features you might prefer. With double-hung windows vs. single-hung or casement windows, you can lock the bottom sash and open just the top sash to keep children and dogs or cats safe.
High winds can be harmful to casement windows and all types of windows. Because casement windows can swing outward, high winds could slam the window against the side of the house, bend the hinges, or even rip the window off of the hinges. If you hear some strong gusts outside, it’s best to pull the casement windows shut until it all blows over.
