How to Troubleshoot and Fix an Andersen Casement Window That Won't Close

Andersen casement windows are known for their durability and ease of use. However, like any other window, they can sometimes experience issues that prevent them from closing properly. If you're facing this problem with your Andersen casement window, don't worry – we've got you covered. In this comprehensive guide, we'll walk you through the steps to diagnose and fix the issue, ensuring your window is back in working order in no time.

Identifying the Problem

Before diving into the solutions, it's essential to identify the root cause of the problem. There are several reasons why an Andersen casement window may not close properly:

1. Sash issues: The sash may be warped, damaged, or misaligned, preventing the window from closing.

2. Hardware problems: The window's hardware, such as the hinges, operator, or handle, may be damaged or malfunctioning.

3. Obstructions: Debris or dirt may be obstructing the window's tracks or hinges, preventing it from closing smoothly.

4. Weatherstripping issues: Damaged or worn-out weatherstripping can cause the window to get stuck or not seal properly when closed.

Inspecting the Window

Before attempting any repairs, it's essential to thoroughly inspect your Andersen casement window to determine the cause of the issue. Follow these steps to inspect your window:

1. Check the sash: Examine the window sash for any signs of warping, damage, or misalignment. If you notice any issues, this may be the cause of your problem.

2. Inspect the hardware: Look for any visible damage or wear on the window's hinges, operator, and handle. If any of these components appear to be damaged or malfunctioning, they may need to be replaced.

3. Look for obstructions: Open the window fully and inspect the tracks and hinges for any debris, dirt, or other obstructions that could be preventing the window from closing smoothly.

4. Examine the weatherstripping: Check the weatherstripping around the window for any signs of damage or wear. If it appears to be in poor condition, it may need to be replaced.

Fixing the Issue

Once you've identified the cause of your Andersen casement window not closing properly, it's time to address the issue. Here's how to fix the most common problems:

Addressing Sash Issues

If the sash is warped, damaged, or misaligned, you may need to replace it. To do this, follow these steps:

1. Remove the sash: Open the window fully and carefully remove the sash from the hinges by lifting it up and out of the hinge channel.

2. Order a replacement sash: Contact Andersen or an authorized dealer to order a replacement sash that matches your window's specifications.

3. Install the new sash: Once you've received the replacement sash, carefully install it by sliding it into the hinge channel and securing it in place.

Repairing Hardware Problems

If the window's hardware is damaged or malfunctioning, you may need to replace the affected components. Here's how:

1. Remove the damaged hardware: Unscrew and remove the damaged hinges, operator, or handle from the window.

2. Order replacement hardware: Contact Andersen or an authorized dealer to order the necessary replacement hardware.

3. Install the new hardware: Once you've received the replacement parts, carefully install them according to the manufacturer's instructions.

Clearing Obstructions

If debris or dirt is obstructing the window's tracks or hinges, follow these steps to clear the obstructions:

1. Clean the tracks and hinges: Use a soft brush or cloth to gently clean the window's tracks and hinges, removing any dirt or debris.

2. Lubricate the hardware: Apply a silicone-based lubricant to the hinges and operator to ensure smooth operation.

Replacing Weatherstripping

If the weatherstripping is damaged or worn out, you'll need to replace it to ensure your window closes and seals properly. Here's how:

1. Remove the old weatherstripping: Carefully peel off the old weatherstripping from around the window.

2. Measure and cut the new weatherstripping: Measure the length of the window's perimeter and cut the new weatherstripping to size.

3. Install the new weatherstripping: Carefully press the new weatherstripping into place around the window, making sure it forms a tight seal.

By following these steps, you should be able to diagnose and fix the issue with your Andersen casement window that won't close. Remember, if you're unsure about any aspect of the repair process or need further assistance, it's always best to consult with a professional window technician to ensure the job is done correctly and safely.

This newly built private house is in Sydney, Australia. The area occupied by the fenestration system in our scheduled design drawings was up to more than 110 square meters. A wide range of design details made the perfect mix of modern aesthetics and traditional sophistication, the simulated vertical hung windows with tilt & turn opening systems in this home are absolutely breathtaking.

Doorwin’s 61S simulated hung windows with tilt & turn openings is a respectful modernization of a classic architectural masterwork.

Why choose the tilt and turn opening method?

Because it generally has better air seals than sliding, single hung, or double hung window frames. Tilt and turn windows form a complete seal when fully closed, this means they are less prone to water leakage, and cold draughts and you’ll keep more of your heating indoors where it belongs. They can be opened in the upper tilt way to ventilate at a minimum opening status and are easy to clean outside of the glass; when there’s a good day, they can be opened as normal inward casement windows.
