Casement windows are a popular choice for homeowners due to their ease of operation and ability to provide excellent ventilation. However, over time, the crank mechanism that allows these windows to open and close can become worn or damaged. In this blog post, we will provide you with a step-by-step guide on how to repair a casement window crank, ensuring that your windows continue to function smoothly and efficiently.
Before diving into the repair process, it's important to first identify the issue with your casement window crank. Common problems include:
1. The crank handle is difficult to turn or doesn't turn at all.
2. The window doesn't open or close properly.
3. The window sash doesn't stay in place when opened.
Once you've determined the issue, you can gather the necessary tools and materials to begin the repair process.
To repair a casement window crank, you'll need the following tools and materials:
Screwdriver
Adjustable wrench
Replacement casement window crank (if necessary)
Lubricant (such as silicone spray or lithium grease)
Clean cloth or rag
To access the crank mechanism and determine the cause of the problem, you'll need to disassemble the casement window crank. Follow these steps:
1. Remove the crank handle by loosening the set screw located on the base of the handle. Use a screwdriver to turn the screw counterclockwise until the handle can be pulled off the crank mechanism.
2. With the handle removed, you should now be able to see the crank mechanism. Inspect it for any visible signs of damage, such as stripped gears or a broken crank arm.
3. If the crank mechanism appears to be in good condition, try turning it with your hand or an adjustable wrench. If it's difficult to turn or doesn't turn at all, the issue may be due to a lack of lubrication.
If the crank mechanism is difficult to turn or doesn't turn at all, applying a lubricant can often resolve the issue. Follow these steps to lubricate the casement window crank:
1. Clean the crank mechanism and surrounding area with a clean cloth or rag to remove any dirt, debris, or old lubricant.
2. Apply a generous amount of lubricant (such as silicone spray or lithium grease) to the crank mechanism, focusing on the gears and any moving parts.
3. Turn the crank mechanism several times to work the lubricant into the gears and moving parts.
4. Reattach the crank handle and test the window to see if the issue has been resolved. If the window still doesn't operate smoothly, it may be necessary to replace the casement window crank.
If lubricating the crank mechanism doesn't resolve the issue, you may need to replace the casement window crank. Follow these steps to replace the crank:
1. Remove the crank handle as described in the disassembling section.
2. Use a screwdriver to remove the screws that secure the crank mechanism to the window frame.
3. Carefully remove the crank mechanism from the window frame.
4. Install the new casement window crank by aligning it with the screw holes in the window frame and securing it with screws.
5. Reattach the crank handle and test the window to ensure it operates smoothly.
If your casement window doesn't stay in place when opened, the issue may be with the window sash or the sash lock. Follow these steps to troubleshoot the issue:
1. Inspect the window sash for any visible signs of damage, such as a bent or warped frame. If the sash is damaged, you may need to replace it or have it repaired by a professional.
2. Check the sash lock to ensure it's functioning properly. If the lock is damaged or doesn't engage properly, you may need to replace it.
By following this comprehensive guide, you should be able to identify and repair any issues with your casement window crank, ensuring that your windows continue to operate smoothly and efficiently. Remember, regular maintenance and lubrication of your casement window cranks can help prevent issues from arising in the first place, so be sure to keep your windows in top condition.
Casement windows are the most common style of window. They feature hinged panels that swing open and closed. Casement windows are available in single panels or multiple panels. The direction a door swings, either to the right or the left, is called the handing. In addition to handing, window are identified as either inswing or outswing depending on whether they open into the house or towards the outside.

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. SDLS (Simulated Divided Lites with Spacer Bar) brings some historical vintage feeling to the whole building without losing any energy saving performance. Long narrow fixed windows creating larger-than-life expenses, coupled with German high-end systems made this project stand out from the rest.
The client's idea was to maintain a certain vintage feel, and our aim was to meet the energy efficiency needs and standards of modern houses as much as possible while maintaining a retro design. 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.
Our well-crafted bespoke systems enhance the functionality and panoramic view of this modern house.
Huge, fixed glass walls up to seven meters long and two meters high bring great lighting and open views, making it really refreshing to the mind. Five meters high long narrow windows give the whole building a contemporary aesthetic.
Every window’s placement and shape not only add to the uniqueness of this home but also provide a more energy-saving ability for the owners.
Doorwin energy-efficient integrated glazing units feature double-pane glass, warm-edge spacers, argon gas fill, Low-E coatings, and fully tempered glass, they can not only create a comfortable and natural indoor environment but also save electricity bills and heating bills of more than 100 USD for the owner, it’s a real bargain compared to choosing a regular glazing set.
Aluminum Door offered an air of uniqueness and elegance to a home. With their luxurious patterns and beautiful finishes, it provides this house with a bounty of aesthetics and security. Aluminum entry doors allow you to resist any weather extremes, corrosion, and pests. So aluminum is one of the most resilient and durable materials you can select for front doors considering the price/performance ratio.
With pieces of double panes, and Low-E tempered glass. The door provides a good insulation performance.
