A casement window is perhaps the oldest form of moveable window&#; , and essentially is hinged to the frame so the window opens much like a door. An individual casement window panel is called a casement sash. Overtime you might encounter problems with the window sash, frame, or hardware.

All of these components contain moving parts that must be maintained for them to work properly, and these are where most issues occur.

A hinge arm or hinge arms are used to keep the window stable as it opens and closes. A crank and a gear system attached to those arms enables opening and closing the window by turning the crank handle.

Casement windows are hinged on the top and bottom of each casement sash. Many casement windows have multiple casement sashes, and each opens independently of the others, but if they come together at a central point, they may share a latch or locking system.

Common Casement Window Problems

What are the most common casement window issues? There are a few, and some will likely be covered by a manufacturer&#;s warranty.

1. Casement Window Will Not Close All the Way

This is a common issue and could be due to a couple of reasons. The hinge arms could be binding, stuck, or damaged. Also, the casement sash may have debris or dirt stuck on the outside that makes it difficult to close.

Also, check to make sure that the lock is not in a locked position and blocking the window from closing all the way. A quick inspection will often reveal the problem.

2. Casement Window Stuck Shut

If a casement window is stuck shut, first check to make sure that the lock is not engaged or sticking. If it still refuses to open, try to move it outward gently. Often in aging casement windows the hinge arms may be stuck or damaged, and attempting to force them open can cause serious damage.

As this point, call a local window professional to come inspect the window and make any repairs. Some windows may be covered under warranty.

3. Broken Casement Window Crank

It is possible that the casement window crank can stop working. This can happen for a variety of reasons. The crank handle itself can be stripped, and the gears inside may no longer be gripping the gear mechanism properly. Usually, the handle can be removed and you can examine it pretty easily.

Sometimes rust and maybe even dirt and grime can build up in the gear mechanism, causing them to stick and even fail. If unlubricated for several seasons, the gears can even become stripped. To prevent this, use the recommended lubricant to maintain the windows. If the gears are already stripped, contact your local window professional to repair them.

The handle can also break over time, but it often does so because of stripped gears or a sticking window. Instead of simply replacing the handle, it is a good idea to check for other issues at the same time.

And if the crank pops out when closing the window, it is also a good idea to inspect for other issues as well.

4. Sagging Casement Window Hinges

Some casement sashes can be heavy, depending on the type of window. Hardware strong enough to bear the weight of the sash is important, but even the best of hardware can wear over time. This can cause the frame to bow or warp, or create the need to replace the hinges themselves.

5. Casement Window Lock Problems

The lock mechanism on a casement sash can have issues, but most often these are due to other issues, like sagging hinges or warped frames that no longer allow the lock parts to align. But the locks can also stick if they are not properly lubricated, or they can become bent or damaged over time.

If the lock mechanism is not working and it is not something you can fix yourself, contact a window professional right away.

6. Damaged weatherstripping

Another common issue with casement windows is worn weatherstripping. Since windows are opened more often, they occasionally pull at the weatherstripping or even compress it more than other window styles. If opened when it is cold or if it has been a while since the window was opened, it is possible for it to stick to the weatherstripping and tear it upon opening.

This can cause everything from drafts to moisture leaks. Be sure to replace any damaged weatherstripping right away to ensure your windows are operating as efficiently as possible.

Letting the air in

When it comes to casement windows, one feature to keep in mind is air flow. Their unique hinged design makes them great at capturing the air that travels along the outside of your home, &#;scooping&#; it inwards for a refreshing breeze. The entire sash (part of the window that opens and closes) opens, allowing for ventilation across the entire open area &#; where as double-hung window sashes can slide upwards from the bottom of the window or downwards from the top, but the sash will still cover a portion of the window opening. This makes casements a great style option for homeowners who enjoy having windows open, or for rooms that can benefit from additional ventilation, like kitchens or bathrooms.

Casement windows are also a great option during cooler months. Because they have one sash to seal (rather than two), they will typically have slightly lower air leakage (the measurement of how much air will enter a room through a product). When strong winds blow against a casement window, it presses the window against the frame and the window's seal.

Beyond temperature control and ventilation, casement windows are easy to clean, simple to operate, and come in a variety of styles that can change the way they look, operate, and control airflow. See what casement window styles you can choose from below.
