Looking after your Composite Doors

Maintaining your composite door is fairly simple and straightforward compared to other materials such as wood, which requires annual treatment.

Frame and slab

To clean down your door simply use a bucket of warm soapy water and a soft cloth. Do not use rough or abrasive materials as it could damage it. If you do this regularly then your door will not collect enough dirt and grime and you will not have to clean it so vigorously.

Make sure any drainage holes are clear.


Clean down the glass with a generic glass cleaner. No need to worry about any of this getting on your frames.


It is important to lubricate your door around every 6 months. Making sure you have the right lubrication is paramount. For hardware such as hinges, handles, letterplates and knockers, we recommend using a light engineering oil such as 3-in-1 or similar. Avoid using WD-40 or other cleaning agents, as these products tend to dry out quickly and won’t lubricate your door for long. For the locking mechanism, look to use a Teflon-based lubricant, which works to reduce friction and wear. Do not use oil or graphite powder as this will do more harm than good.

Seals and gaskets

Check seals and gaskets. If any have become dislodged, they should be relatively easy to slide back into their grooves.

Treat your comp door like a car door. Try to avoid scraping it or pushing bags against it. Use the handle to operate. Always engage the locking system when not in use.

Door won’t shut properly

If you find that your composite door won’t shut properly or is difficult to open and close, this could happen over time as a result of the door dropping or not being closed properly throughout it’s lifetime.

Making sure you shut the door correctly when you enter or leave your home will help to prevent any further problems. Making sure you ‘throw’ the handle to ensure both the top and bottom of the door is hooked in properly can help to prevent problems occurring over the long-term.

Even with regular maintenance, it’s perfectly normal for door hinges to drop, and you can even fix this yourself with the correct tools.

Composite doors are fitted with self-lubricating bearings, meaning your hinges only require minimal maintenance. The hinges may likely drop when a composite door is in constant use. If this occurs, it’s solved with a minor hinge adjustment.

Like sticking locks, you need to carry out basic hinge maintenance from time to time, and you can do this by spraying the hinges with a light oil lubricant every couple of months.

Sticky locks

Sticky locks or any other door lock problem, can happen on just about any door if they are not properly maintained or cared for. Composite doors are known for being low maintenance but keeping your lock clean and functioning properly is still importance.

A sticky lock is easy to identify once you experience it for the first time. Poor functionality, difficulty removing your key or extra force to turn the key can all indicate an underlying problem with the locking mechanism. If you want to keep the door lock in top shape and keep stickiness at bay, the best thing to do is to use lubricant in the lock regularly. Maintenance every six months can have long-lasting, positive results for smooth and easy access.
