If your windows are refusing to close properly, it can be a frustrating and potentially concerning issue. Whether the problem is a result of a shifting foundation, warped wood, or simple debris buildup, there are several steps you can take to diagnose and resolve the problem. In this comprehensive guide, we’ll walk you through the common causes of windows that won’t close and provide practical solutions to get your windows functioning smoothly again.
Identifying the Underlying Issue
The first step in fixing windows that won’t close is to determine the root cause of the problem. There are several potential culprits, and the solution will depend on the specific issue you’re facing.
Shifting Foundation
If the foundation of your home has begun to shift, it can cause the window frames to become misaligned, preventing the windows from closing properly. This is particularly common with concrete slab foundations.
To fix a window that’s misaligned due to a shifting foundation, you may be able to simply lift and push the window and the area around the lock to get it back into place. However, if the issue is more severe, you may need to consult a professional foundation repair specialist to address the underlying problem.
Warped Wood
Over time, exposure to moisture can cause the wood in your window frames to warp, leading to misalignment and difficulty closing the windows. This is often the result of old or worn caulk around the window, which allows water to penetrate the frame.
To fix a warped window frame, you may need to replace the damaged section of the frame. In some cases, the wood may dry out and the window may still function properly, but it’s important to address the root cause of the moisture issue to prevent further damage.
Obstructions
Debris, dirt, and even corroded locks can obstruct the smooth operation of your windows, making them difficult to open and close.
In these cases, a simple cleaning and lubrication of the window tracks and mechanisms may be all that’s needed to restore proper function. If the issue is more severe, such as a damaged lock, you may need to replace the affected components.
Damaged Window or Frame
If the window itself or the surrounding frame is damaged, it may be impossible to get the window to close properly. In these cases, the only solution may be to replace the entire window unit.
