Casement windows are a popular choice for many homeowners due to their ease of use and excellent ventilation. However, like any other window type, they can sometimes develop issues that prevent them from closing properly. If you find yourself struggling with a casement window that won't close, don't worry—this guide will walk you through the steps to diagnose and fix the problem.

1. Identify the Problem

Before you can fix the window, you need to determine what's causing the issue. Common problems with casement windows that won't close include:

• Obstructions: Dirt, debris, or foreign objects can get lodged in the window track or hinges.
• Warped Frame: Wood frames can warp over time due to moisture, making it difficult for the window to close properly.
• Faulty Hardware: Broken or misaligned hardware, such as hinges, cranks, or locks, can prevent the window from closing.
• Paint Buildup: Layers of paint can interfere with the window's operation.

2. Gather Necessary Tools

Depending on the identified problem, you may need some or all of the following tools:

• Screwdriver
• Pliers
• Utility knife
• Lubricant 
• Sandpaper
• Replacement parts (if necessary)
• Cleaning supplies

3. Clean the Window

Start by cleaning the window thoroughly. Remove any dirt, debris, or obstructions from the track and hinges using a brush or vacuum cleaner. Sometimes, a simple cleaning can resolve the issue.

4. Inspect and Adjust the Hardware

Check the window's hardware for any signs of damage or misalignment. Tighten any loose screws and ensure the hinges and crank mechanism are functioning properly. If the hardware is damaged, you may need to replace it. Here’s how to do it:

• Hinges: If the hinges are bent or broken, unscrew them from the frame and replace them with new ones.
• Crank Mechanism: If the crank is not operating smoothly, it may need lubrication. Apply a small amount of lubricant to the gears and moving parts. If the crank is broken, replace it by unscrewing the old one and installing a new mechanism.

5. Check for Warped Frames

If the window frame is warped, it can be more challenging to fix. Minor warping can sometimes be corrected by sanding down the high spots until the window fits properly. For more severe warping, you might need to replace the entire window frame or consult a professional.

6. Remove Excess Paint

Excess paint can cause the window to stick. Use a utility knife to carefully remove any paint buildup from the window frame and moving parts. Sand down any rough areas to ensure smooth operation.

7. Lubricate Moving Parts

Lubricate all moving parts, including hinges, tracks, and the crank mechanism, with a silicone-based lubricant. Avoid using oil-based lubricants as they can attract dirt and cause further issues.

8. Test the Window

After making the necessary adjustments and repairs, test the window to ensure it opens and closes smoothly. If it still doesn't close properly, re-examine each component to identify any issues you may have missed.

9. Seek Professional Help if Needed

If you've tried all the above steps and the window still won't close, it may be time to call in a local professional. A skilled window repair technician can diagnose and fix more complex issues that you might not be able to handle on your own.

Conclusion

Fixing a casement window that won't close can be a straightforward task if you identify the problem and follow the correct steps. Regular maintenance and prompt repairs can keep your windows in good working condition and prolong their lifespan.
