When Looking After Your Door

Every Month

Wipe down the door with a damp, lint-free cloth using only mild warm soapy water.

To keep your furniture sparkling, we recommend wiping it with a clean cloth soaked in warm water and mild detergent every month. Moving parts should be lightly lubricated twice a year.

Every 6 Months


Open the door and place an old sheet underneath it. Lubricate all of the moving parts with silicone spray, apart from the locking cylinder.

To maintain the smooth operation of your locking cylinder, lubricate your cylinder using graphite powder. Dust your key with graphite powder and move it back and forth in the cylinder 10-15 times to fully lubicate.

What Should I Consider?

Cleaning Your Door

To keep your composite door looking fresh, all you will need to do is give it a light clean with mild, soapy water. If you find yourself facing tough stains, it is important to note that you should never use an abrasive cleaner. This includes PVC cleaner, as you can remove any stubborn stains by using a non-abrasive cleaner. Further to this, ensure drainage holes are clear on a yearly basis.

Using Your Door Properly

To avoid any damage to the door panel, it’s important that you close the door properly. This includes ‘throwing the handle’ when the door is closed, which engages the top and bottom hooks for increased security and support. If you do not throw the handle you will leave the door solely on the latch, which can cause problems in the long run.

Cleaning Door Furniture

We know that keeping up appearances is important when it comes to your home, which is why it is important to keep the door furniture (handles, hinges, numerals etc.) looking nice and clean. To do this, we recommend you wipe it with a clean cloth soaked in warm water and mild detergent every month. This way, you’ll maintain a consistent appearance.

Maintaining Your Lock

The lock is a key player in ensuring your door can protect your home, so it’s useful to know how to look after it. To maintain smooth and consistent operation, all you will have to do is lubricate the working parts of the mechanism at least every 6 months. If you have any questions, don’t hesitate to get in touch with your nearest Endurance Installer.

Adjusting Your Hinges

Over constant use, it is natural for your door to need some hinge adjustment. To keep the door in top shape, all you will have to do is adjust the screws on the hinges or adjust the locking keeps from time to time. This means that your door will sit perfectly as it was installed to do, allowing you to enjoy simple and efficient operation.
