Can I Replace Casement Windows with Double Hung? A Comprehensive Guide


When it comes to home improvement, one of the most significant changes you can make is replacing your windows. Not only do new windows enhance the appearance of your home, but they also provide better energy efficiency and functionality. If you have casement windows in your home and are considering replacing them with double hung windows, you're not alone. Many homeowners find themselves asking, "Can I replace casement windows with double hung windows?" The answer is yes, and this comprehensive guide will walk you through the process and explore the benefits of making this change.

The Difference Between Casement and Double Hung Windows

Before diving into the process of replacing casement windows with double hung windows, it's essential to understand the differences between these two window styles.

Casement Windows

Casement windows are hinged on one side and open outward, usually with a crank or lever. They provide excellent ventilation and unobstructed views when open. Casement windows are ideal for hard-to-reach areas, such as over sinks or countertops, because they can be easily operated with one hand.

Double Hung Windows

Double hung windows have two sashes that slide vertically, allowing you to open the top, bottom, or both for ventilation. This classic window style is found in many homes and offers a timeless appearance. Double hung windows are easy to clean, as both sashes can be tilted inward for easy access to the exterior glass.

Benefits of Replacing Casement Windows with Double Hung Windows

There are several advantages to replacing your casement windows with double hung windows. Some of the most notable benefits include:

1. Improved Energy Efficiency:Double hung windows often provide better energy efficiency than casement windows because they create a tighter seal when closed. This can help lower your heating and cooling costs and make your home more comfortable year-round.

2. Easier Maintenance:As mentioned earlier, double hung windows are easier to clean than casement windows because both sashes can be tilted inward. This makes it simple to clean the exterior glass without having to go outside or use a ladder.

3. Increased Home Value:Updating your windows can significantly increase the value of your home. Double hung windows are a popular choice among homebuyers, so making this change can make your home more attractive on the market.

4. Aesthetic Appeal:Double hung windows offer a classic, timeless look that can enhance the overall appearance of your home. They are available in a wide variety of materials, colors, and finishes, allowing you to customize the look to suit your home's style.

The Process of Replacing Casement Windows with Double Hung Windows

Now that you understand the benefits of replacing your casement windows with double hung windows, let's discuss the process involved.

1. Measure Your Windows:The first step in replacing your casement windows is to take accurate measurements. Measure the width and height of the existing window opening, as well as the depth of the window frame. This will help you determine the correct size of the replacement double hung windows.

2. Choose Your New Windows:With your measurements in hand, you can now select your new double hung windows. Consider factors such as energy efficiency, material, and style when making your decision. It's also essential to choose windows that meet your local building codes and requirements.

3. Remove the Old Casement Windows:Before installing the new double hung windows, you'll need to remove the existing casement windows. This process will vary depending on the specific type of casement window you have. In most cases, you'll need to remove the sash and any hardware, such as the crank or lever, before removing the window frame.

4. Install the New Double Hung Windows:Once the old casement windows have been removed, you can begin installing the new double hung windows. Follow the manufacturer's instructions for proper installation, ensuring a tight seal and proper operation of the sashes.

5. Finish the Installation:After the new double hung windows are in place, you'll need to finish the installation by sealing any gaps with caulk or insulation, installing any necessary hardware, and painting or staining the window frame as desired.

Final Thoughts

In conclusion, replacing casement windows with double hung windows is a worthwhile investment that can improve your home's energy efficiency, functionality, and appearance. By following the steps outlined in this guide, you can successfully make this change and enjoy the benefits of your new double hung windows for years to come.

Casement Window


Casement windows are the most common style of window. They feature hinged panels that swing open and closed. Casement windows are available in single panels or multiple panels. The direction a door swings, either to the right or the left, is called the handing. In addition to handing, window are identified as either inswing or outswing depending on whether they open into the house or towards the outside.
