What Is a Casement Window?
A casement window opens outward like a door. It has one or two hinges on the side and opens fully to the left or right by a cranking handle mechanism. This style lets in breezes and improves airflow in the home.
Whether you’re considering installing casement windows for new construction or an upcoming remodel, our guide will help you understand the pros and cons of this type of window. We’ll also compare casement windows with other window options.
Pros of Casement Windows
Casement windows are functional and energy-efficient while providing beautiful views of the outdoors. Homeowners with casement windows enjoy the following benefits:
Energy Efficiency
Unlike traditional hung or picture windows, casement windows close by pressing against their frames, creating a tight seal. As a result, casement windows don’t allow air leakage and help maintain consistent indoor temperatures. You may enjoy lower energy bills year-round with casement windows installed.
Ventilation
Casement windows open fully by swinging outward, providing ventilation. This window type allows more fresh air inside than double-hung windows, which often have unopened parts.
Unobstructed View
Since casement windows operate like a door, you can open them fully and enjoy an unobstructed view of the outdoors. The single-sash design, coupled with minimal framework, allows homeowners to take in the beauty of their surroundings.
Simplified Operation and Cleaning
Unlike windows that require lifting or sliding, casement windows open with a straightforward crank mechanism. The simple design and operation of casement windows contribute to ease of cleaning. Since you can open each window fully, it’s possible to reach all the corners of the glass and frames.
Cons of Casement Windows
While casement windows have many advantages, they are expensive and have some limitations. Review the following drawbacks of casement windows before choosing them for your next window project.
Cost
Casement windows are more expensive than many other typical window types. Depending on window size, style, and material, the average cost of casement windows is between $600 and $1,400.

Potential Mechanical Failures
Casement windows rely on hinges and cranks to open and close. These mechanical components can fail over time, so invest in regular cleaning and maintenance to prevent this issue.
Limitations
Casement windows are usually available in standard sizes, which limits opportunities for customization. Also, because of the window’s structure, an air conditioner unit cannot be installed in a casement window.
Safety Concerns
While casement windows offer advanced ventilation, they may not be as safe as other window types. Their outward-swinging design makes them more vulnerable to break-ins, and poorly installed or worn hinges could make it easier for intruders to access your home.
Casement Windows vs. Hung Windows
Hung windows, which open and close vertically, are a common window choice. Review how hung windows differ from casement windows in design, functionality, and more.
Design
Hung windows slide open and closed vertically. You operate them by pushing the sash up and down. These windows are popular thanks to their simplicity and cost-effectiveness. They can either be single-hung (when just the lower part of the window moves) or double-hung (when both the upper and lower parts of the window can slide).

Functionality
Casement windows are more functional than hung windows because they open fully. They provide excellent ventilation control when opened and a tight seal when closed. Thanks to the crank mechanism, these windows are easy to operate.
While hung windows are less functional, they can accommodate an air conditioner. With double-hung windows, you can choose how to keep them open.
Placement
Casement windows function well in hard-to-reach areas where sliding the sash can be problematic (for example, above countertops or kitchen sinks). They are also appropriate in areas where increased ventilation is welcome (kitchens and bathrooms).
Hung windows can be installed in any room where sufficient access is available for operation. They are also good in areas where exterior obstructions may limit the use of casement windows.
Installing Casement Windows
Casement window installation is rarely a DIY project. While these windows are easy to operate, they are complex to install correctly. Here are the steps to install a casement window to give you an idea of what window installation is like:
Step 1: Prepare the Opening
Measure the existing window or the window opening to ensure you buy the right replacement window. Remove the old window, frame, trim, and debris from the opening.
Place the new window into the opening to check that it fits properly. You may need to adjust the opening’s structure to ensure an ideal fit.
Step 2: Insert the Window
Apply high-quality sealant around the perimeter of the opening. Then, insert the window and check that it fits well. Use a level to ensure the window is positioned correctly.
Step 3: Secure the Window
Secure the window in place by driving screws through the pre-drilled holes in the frame and into the wall studs. Follow the window manufacturer’s recommendations about placing the screws. Then, fill the gaps between the frame and the opening with expanding foam.
Step 4: Install Trim
Install interior and exterior trim around the window frame to cover any gaps. Finishing nails secure the trim in place. Trim installation is one of the trickiest parts of your casement window project. It requires precise measurements and seamless placement.
Step 5: Apply Finish
After testing the window to ensure it operates properly, you can paint or stain the window frame.
The installation process may vary depending on the window brand and the characteristics of your home’s structure. In most cases, homeowners prefer outsourcing this job to professionals.
The nuances of casement window installation create many opportunities for mistakes. A poorly installed casement window could cause mold growth, drafts, and security issues.
Maintaining Casement Windows
Casement windows don’t require complicated maintenance. However, without proper care, they can wear out. Here are a few practices to implement:
Clean Regularly
Clean the glass and frame of the window regularly using a mild detergent and water solution. Avoid using abrasive cleaners or rough materials that could scratch the glass. Clean the frame at least once a month and wash your windows at least twice a year.
Check the Seals
Inspect seals and weatherstripping on your window each year. If you notice any damage or wear, replace the seals. Also, check for gaps between the window and the wall. If any appear, use a sealant to fill them immediately.
Inspect the Hardware
While checking the seals, pay attention to hinges, handles, and locks. If you notice any signs of rust or corrosion, remove it immediately. The durability and longevity of your window depend on how fast you fix minor problems.
Lubricate the Crank Mechanism
Lubricate the crank mechanism once a year. Use a silicone-based lubricant or light machine oil to lubricate all the moving parts, including hinges and gears. Apply the lubricant sparingly to avoid excess buildup, which can attract dirt.
Repaint or Refinish
If you have clad wood or wood casement windows, repaint or refinish them every few years. It will protect the frame from moisture and UV damage.
Our Conclusion
Casement windows are functional windows that can be installed in any room. They are easy to operate and clean while being aesthetically appealing and versatile. These low-maintenance windows can be an excellent choice if you want a simple method of opening a window.
While it may be possible to install these windows yourself, the process is complicated. Consider professional installation with a warranty to prevent errors and ensure window longevity.
