Casement Window Cost Factors
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.
Size
Casement windows range from about $260 for a standard 24-inch-by-36-inch window to around $630 for a 36-by-60-inch window. The larger the window, the more it will cost for materials and installation.
Some common casement window sizes and their costs include:
| Window Size (In.) | Cost |
|---|---|
| 24-by-36 | $260–$360 |
| 24-by-48 | $350–$515 |
| 24-by-60 | $420–$450 |
| 30-by-36 | $275–$400 |
| 30-by-38 | $215–$470 |
| 30-by-60 | $460–$480 |
| 36-by-60 | $335–$630 |
Material
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.
| Material | Cost (Material Only) |
|---|---|
| Wood | $260–$2,000 |
| Vinyl | $200–$780 |
| Aluminum | $200–$1,180 |
| Fiberglass | $535–$1,575 |
| Composite | $350–$1,450 |
Number of Panes
You may opt for single, double, or even triple-pane windows. The more panes, the more energy-efficient and insulating the windows will be. In most cases, double-pane windows cost about $150 more than single-pane windows, and triple-pane windows cost about $250 to $550 more.
| Number of Panes | Average Cost |
|---|---|
| Single | $150–$400 |
| Double | $150–$600 |
| Triple | $400–$950 |
Energy Efficiency
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.
Casement Window Type
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. Take a look at some of the most popular types of casement windows and their 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 |
Number of Windows
If you have multiple casement windows, it may be more cost-effective to replace them all at once. Manufacturers may offer discounts for more than one window, and if the installer is already on site to replace one window, they may offer lower labor costs for multiple windows.
Brand
The brand of casement window you choose will also affect the cost. Expect to pay more for higher-end brands, while more budget-friendly brands may offer less expensive options.
| Brand | Average Cost |
|---|---|
| Pella | $475–$1,800 |
| Andersen | $425–$1,600 |
| Jeld-Wen | $250–$1,100 |
| Simontin | $200–$1,300 |
Labor
Hiring a professional window installer will add about $100 to $300 per window to the casement window 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.
Prep
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.
Ongoing Casement Window Costs to Consider
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.
Repairs
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.
Maintenance
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.
Permits
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.
DIY vs. Hiring a Pro to Install Casement Windows
Homeowners with experience installing casement windows and all the necessary tools can save on installation costs. DIYing casement window installation costs about $200 to $2,000 for the window materials. Since improper window installation can result in damage to your home, water intrusion, increased energy costs, or even broken glass, hiring a window replacement specialist is your best bet unless you have extensive window installation experience.
A local window contractor will properly install your casement window, ensuring that there are no gaps, safety concerns, or damage. The extra $100 to $300 per window in installation costs can give you the peace of mind that your windows are correctly installed.
Cost of Common Casement Window Add-Ons
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

Frequently Asked Questions
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.
