Crank windows, also known as casement windows, are popular for their ease of use and ability to provide excellent ventilation. However, over time, they may develop issues such as difficulty in opening or closing, a broken crank handle, or a malfunctioning operator. If you're experiencing problems with your crank windows, don't worry! This guide will walk you through how to fix crank windows quickly and efficiently.

Common Issues with Crank Windows

Before diving into the repair process, it's essential to identify the exact problem with your crank window. Some common issues include:

• Stiff or stuck windows – This may be due to dirt buildup, rust, or a misaligned mechanism.

• Broken crank handle – The handle may break due to frequent use or excessive force.

• Stripped gears in the operator mechanism – This can prevent the window from opening or closing properly.

• Worn-out hinges – If the window sags or doesn’t close completely, the hinges may need replacement.

To fix your crank window, you will need -
