UPVC window stays play a crucial role in ensuring the proper functioning and longevity of your windows. They provide support to keep windows open securely, allowing for ventilation and fresh air circulation. However, like all mechanical components, UPVC window stays require regular maintenance to perform optimally. Here are some essential maintenance tips to keep your UPVC window stays in top condition:

Visual Inspection and Cleaning

Regularly inspect your window stays for any physical damage or signs of wear, such as cracks, chips, or loose parts. Clean them thoroughly with a soft cloth and warm, soapy water. Avoid using harsh chemicals or abrasive cleaners, as these can damage the surface.


Moving parts within UPVC window stays, such as hinges and gears, need to be lubricated periodically. Apply a few drops of silicone spray or a light machine oil to these areas to reduce friction and ensure smooth operation. Wipe off any excess lubricant to prevent dust and dirt from sticking.

Tightening Screws

Over time, screws and bolts holding the window stays in place may become loose due to vibrations or environmental factors. Inspect the fasteners regularly and tighten any loose ones using a suitable screwdriver. Ensure not to overtighten, as this can strip the screws or damage the stay.

Adjusting Tension

Many UPVC window stays feature an adjustable tension mechanism that allows you to fine-tune the force required to open or close the window. If you notice any difficulty in operating the window, check the tension setting and adjust it as needed.

Replacing Worn Parts

If you notice any significant wear or damage to any components of your window stays, such as broken hinges or stripped gears, it’s advisable to replace them promptly. Use genuine replacement parts from the manufacturer or an authorized distributor.

Periodic Inspection and Maintenance Schedule

Establish a regular maintenance schedule for your UPVC window stays. This could involve inspecting and cleaning them every three to six months, lubricating them annually, and tightening screws or adjusting tension as needed. Sticking to a maintenance routine will help prevent problems and extend the lifespan of your window stays.


Proper maintenance of your UPVC window stays is essential to ensure their reliable operation and prevent costly repairs down the road. By following these simple maintenance tips, you can keep your window stays in top condition, ensuring the smooth and secure functioning of your windows for years to come.
