A Comprehensive Guide to Jalousie Window Hardware Repair

Home windows play a crucial role in enhancing the aesthetic appeal, functionality, and energy efficiency of a house. Jalousie windows, known for their unique design and practical ventilation benefits, are a popular choice for many homeowners. However, like any other window type, jalousie windows may require occasional maintenance and repair. In this guide, we will delve into the world of jalousie window hardware and provide valuable insights into repairing these distinctive windows.

Understanding Jalousie Windows:

Jalousie windows, also known as louvre windows, consist of multiple horizontal glass slats or blades that open and close in unison. These slats are attached to a metal or plastic mechanism that allows users to control the amount of ventilation by adjusting the angle of the slats. While jalousie windows are renowned for their ability to provide excellent airflow, the intricate hardware involved can sometimes lead to issues that necessitate repair.

Common Jalousie Window Hardware Issues:

Worn or Broken Crank Handles:

  • The window operator is an essential component that controls the opening and closing of jalousie windows using a crank handle. Over time, handles may become worn or broken, requiring replacement. To fix this issue, homeowners can purchase replacement handles from hardware stores or online suppliers (that’s us!), ensuring they match the specific model and size of their existing hardware.


Damaged Linkages:

  • The linkages are the metal arms that connect the crank handle to the individual glass slats. Damaged or bent linkages can hinder the smooth operation of the jalousie window. Replacing these linkages involves removing the old ones and installing new ones with the help of basic tools such as pliers and screwdrivers.

Stuck or Misaligned Slats:

  • Jalousie window slats can become stuck or misaligned due to dirt, debris, or rust accumulation in the track. Regular cleaning and lubrication of the tracks can prevent these issues. In cases where slats are damaged, they may need to be replaced, requiring the removal of the frame and careful installation of new slats.


Rusty or Corroded Hardware:

  • Exposure to the elements can cause jalousie window hardware to rust or corrode over time. Rust can be removed using a wire brush, and applying a rust-inhibiting primer and paint can help prevent further corrosion. Lubricating moving parts with a silicone-based lubricant can also improve the overall performance of the hardware.


DIY Jalousie Window Hardware Repair Steps:

Gather Necessary Tools and Materials:

  • Before starting any repair work, gather the required tools, including screwdrivers, pliers, wire brush, lubricant, and replacement parts if needed.

 Remove the Window Panel:

  • In some cases, it may be necessary to remove the entire jalousie window panel to access and repair the hardware. Follow the manufacturer's instructions or seek professional guidance if needed.

 Inspect and Identify Issues:

  • Carefully inspect the hardware components, including crank handles, linkages, slats, and tracks. Identify the specific issues that require attention.

Replace Damaged Parts:

  • If any components are damaged beyond repair, replace them with new, compatible parts. Consult the window's manufacturer or a hardware professional to ensure the replacement parts are suitable for your jalousie window model.

Clean and Lubricate:

  • Clean the tracks, linkages, and other moving parts thoroughly. Remove dirt, debris, and rust using appropriate tools. Apply a silicone-based lubricant to ensure smooth operation.

 Reassemble the Window (ICON*):

  • Once the repairs are complete, carefully reassemble the jalousie window, ensuring that all components are securely in place.


Regular maintenance and timely repairs are essential for preserving the functionality and longevity of jalousie windows. By understanding the common hardware issues and following the DIY repair steps outlined in this guide, homeowners can keep their jalousie windows in optimal condition, enjoying the benefits of improved ventilation and a well-maintained home environment.
