Polyvinyl Chloride Unplasticised (UPVC) windows are widely used in modern buildings due to their durability, low maintenance, and energy efficiency. However, like any mechanical component, UPVC window hinges can encounter issues that hinder their proper functioning. This article will address some of the most common problems with UPVC window hinges and provide practical solutions to resolve them.

Sticking Hinges

Cause: Corrosion, dirt, or misalignment can result in hinges sticking and becoming difficult to operate.

Solution: Clean the hinges thoroughly using a damp cloth and a mild detergent. If the problem persists, apply a lubricant specifically designed for hinges. For misalignment issues, consult a professional window technician.

Loose Hinges

Cause: Over time, the screws holding the hinges in place can loosen, causing the hinges to become loose and unstable.

Solution: Tighten the screws using an appropriate screwdriver. If the screws are stripped or damaged, it may be necessary to replace the hinges altogether.

Dropping Windows

Cause: Worn or damaged hinges can lead to the window sash dropping or sagging when opened.

Solution: Inspect the hinges for wear and damage. If necessary, replace the worn hinges with new ones. Additionally, make sure the window frame is level and properly installed.

Hinge Pin Breakage

Cause: Excessive force or improper handling can cause the hinge pins to break, resulting in the window hinge becoming inoperable.

Solution: If the hinge pin is broken, it is recommended to replace the entire hinge. Attempting to repair the hinge pin yourself is not advisable due to the complexity of the mechanism.

Hinge Adjustment

Cause: Over time, UPVC window hinges may require adjustment to ensure smooth operation and proper alignment.

Solution: Some hinges feature adjustable screws that allow for fine-tuning the movement and tension of the hinge. It is important to consult the manufacturer’s instructions for specific adjustment procedures to avoid damaging the hinge.

Lubrication and Maintenance

Cause: Regular lubrication is essential to keep UPVC window hinges functioning smoothly.

Solution: Apply a lubricant specifically designed for hinges to all moving parts every six to twelve months. This will help prevent corrosion, reduce friction, and extend the life of the hinges.


While UPVC window hinges are generally robust and reliable, they can occasionally encounter problems that affect their performance. Understanding the common issues and knowing how to resolve them can help homeowners maintain their windows in optimal condition. By implementing the solutions outlined in this article, you can ensure that your UPVC window hinges function smoothly, provide secure operation, and enhance the overall functionality of your windows.
