Friction hinges, commonly used on uPVC windows and doors, play a crucial role in ensuring smooth operation and longevity. However, over time, friction can build up, resulting in creaking, stiffness, and premature wear. Lubricating these hinges regularly is essential to maintain optimal performance and extend their lifespan.


uPVC-compatible lubricant (silicone, WD-40, or a spray specifically designed for uPVC)

Clean cloth or brush

Gloves (recommended)


1. Ensure Safety:

Wear gloves to avoid contact with the lubricant.

Choose a well-ventilated area to avoid inhaling fumes.

2. Clean the Hinges:

Wipe down the hinges with a clean cloth to remove any dirt or debris.

If the hinges are particularly dirty, use a soft-bristled brush to dislodge any stubborn particles.

3. Apply Lubricant:

Hold the lubricant a few inches from the hinges and spray or apply a small amount directly into the friction points.

Avoid over-lubricating, as excess lubricant can attract dirt and dust.

4. Work the Hinges:

Gently open and close the window or door several times to distribute the lubricant evenly.

If the hinges are particularly stiff, apply a little more lubricant and work them until they loosen up.

5. Wipe Away Excess:

Use a clean cloth to wipe away any excess lubricant that may have dripped or oozed out.

This will prevent it from attracting dirt and impairing the operation of the hinges.

Frequency of Lubrication:

For optimal performance and longevity, it’s recommended to lubricate uPVC friction hinges every six months to one year.

More frequent lubrication may be necessary in areas with frequent exposure to weather or heavy use.

Additional Tips:

To prevent the lubricant from freezing in cold temperatures, choose a lubricant that is designed for outdoor use.

Avoid using household oils, as they can damage uPVC and other plastics.

If the hinges continue to squeak or stick after lubrication, consult a professional to diagnose and resolve the issue.

By regularly lubricating your uPVC friction hinges, you can ensure smooth operation, prevent premature wear, and extend their lifespan. With proper care and maintenance, your windows and doors will open and close effortlessly, adding comfort and value to your home.
