What Is a Casement Window?
If you’re working on a new construction or an upcoming home remodel, one of the factors you’ll need to consider is the window type you want to use. One popular window option is the casement window, which opens outward like a door to let breezes into your home, thereby improving airflow. A casement window has one or two hinges on the side and opens fully to the left or right using a cranking handle mechanism.
Whether you decide to install casement windows yourself or hire a professional, our guide will help you understand the pros and cons of this window type and compare it to 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 may lower your energy bills year-round by preventing air leakage and maintaining consistent indoor temperatures.
Simplified Operation and Cleaning
Unlike windows that require lifting or sliding, casement windows open with a straightforward crank mechanism, similar to a door. This simple design makes casement windows easier to clean because you can open each window fully to reach all corners of the glass and frames.
Unobstructed View
Being able to open casement windows fully also gives you unobstructed views of the outdoors. Their single-sash design and minimal framework allow homeowners to take in the beauty of their surroundings.
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.
Cons of Casement Windows
While casement windows have many advantages, they are expensive and have some limitations. Consider the following drawbacks before choosing casement windows for your next window project:
Cost
Casement windows are more expensive than many other typical window types. The average cost of casement windows ranges from $600–$1,400 depending on window size, style, and material.

Limitations
Casement windows are usually available in standard sizes, which limits customization opportunities. You also cannot install an air conditioner unit in a casement window because of its structure.
Potential Mechanical Failures
Casement windows rely on hinges and cranks to open and close. These mechanical components can fail over time, so you’ll need to invest in regular cleaning and maintenance to prevent this issue.
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. Other Window Types
Next, we’ll compare casement windows to other popular window styles to help you better understand their unique features.
Comparison With Hung Windows
Casement windows differ significantly from hung windows in both design and functionality. Here are some key considerations:
- Casement windows offer superior airflow control and a tighter seal when closed. However, hung windows may be a better choice in areas where an outward-swinging window might create an obstruction or pose a safety concern.
- Hung windows—which include single-hung and double-hung varieties—operate by sliding vertically within the frame, while casement windows swing outward.
- While hung windows are often more affordable and can accommodate air conditioning units, they generally provide less ventilation and are less energy-efficient than casement windows.
Casement vs. Sliding Windows
Sliding windows, which open horizontally along a track, offer different advantages and disadvantages than casement windows. Consider the following differences:
- Casement windows can be easier to operate thanks to their crank mechanism, especially in hard-to-reach areas, while sliding windows may be better suited to wider openings.
- Casement windows tend to be more energy-efficient due to their tight seal when closed.
- Sliding windows are often easier to clean from inside the home.
- Sliding windows typically don’t provide as tight a seal as casement windows and may not offer the same level of ventilation.
Installing Casement Windows
Casement window installation is rarely a DIY project. While these windows are easy to operate, they are complex to install correctly. We’ve outlined the step-by-step installation process below to give you an idea of what window installation is like.
Prepare the Opening
- Measure the existing window or 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.
Insert the Window
- Apply high-quality sealant around the perimeter of the opening.
- Insert the window and check that it fits well.
- Use a level to ensure that you’ve positioned the window correctly.
Secure the Window
- Secure the window in place by driving screws through the predrilled holes in the frame and into the wall studs.
- Follow the window manufacturer’s recommendations regarding screw placement.
- Fill the gaps between the frame and the opening with expanding foam.
Install Trim
Trim installation is one of the trickiest parts of your casement window project. It requires precise measurements and seamless placement. Follow these steps to install your trim:
- Install interior and exterior trim around the window frame to cover any gaps.
- Use finishing nails to secure the trim in place.
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 your home’s structural characteristics.
In most cases, homeowners prefer outsourcing casement window installation to professionals. The nuances of the installation process create many opportunities for mistakes. A poorly installed casement window can cause mold growth, drafts, and security issues.
When To Hire a Casement Window Professional
While DIY installation is possible, hiring a professional is often the best option for casement window installation. Professional installers have the experience and tools to ensure a proper fit and seal. They can also navigate unexpected challenges during the installation process.
Consider professional installation if any of the following apply:
- The installation requires modifying the window opening.
- You’re not comfortable with home improvement projects.
- You’re replacing multiple windows.
- You want to ensure warranty coverage.
Professional installation can provide peace of mind and save you money in the long run by preventing issues caused by improper installation.
Maintaining Casement Windows
Casement window maintenance isn’t complicated, but these windows can wear out without proper care. The following maintenance practices will keep your casement windows in optimal condition:
- Check the seals: Inspect seals and weatherstripping on your window each year. Replace the seals if you notice any damage or wear. You should also check for gaps between the window and the wall. If any appear, use a sealant to fill them immediately.
- Clean regularly: Clean the window glass and frame 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 per year.
- Inspect the hardware: While checking the seals, pay attention to hinges, handles, and locks. If you notice any signs of rust or corrosion, address or remove them immediately. Your window’s durability and longevity 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 to protect the frames from moisture and UV damage.
Enhancing Home Value With Casement Windows
Installing casement windows can enhance your home’s energy efficiency and visual appeal, making them a useful long-term investment to boost your home’s value.
Energy Savings Impact
The energy efficiency of casement windows can significantly lower your utility bills. By reducing air leakage and improving insulation, these windows help maintain consistent indoor temperatures, reducing the workload on your heating and cooling systems. Over time, these energy savings can offset casement windows’ initial higher cost.
Visual Appeal
Casement windows can also improve the look of your home, both inside and out. Their sleek design and large glass area can create a modern, open feel in any room. Their unobstructed views can make spaces feel larger and more connected to the outdoors. This visual enhancement can be particularly valuable if you’re thinking about selling your home.
Our Conclusion
Casement windows are functional, low-maintenance windows that you can install in any room. They are easy to operate and clean while being aesthetically appealing and versatile.
While it may be possible to install these windows yourself, the process is complicated. Consider professional installation with a warranty to prevent errors and extend window lifespan.
