Do composite doors need maintenance to keep them functional? While composite doors are known for their durability and incredibly low maintenance compared to other types of doors, they are not entirely maintenance-free. Over time, regular cleaning and occasional care can help preserve their appearance and functionality.

Composite doors are crafted from a combination of materials and depending on the manufacturer, the materials used may require different cleaning materials or frequency in cleaning. At Endurance, our composite doors are made with a combination of solid timber and heat-reflective PVC skins. These work together to protect your door from the elements and reduce the need for frequent maintenance.
With their specialised design, composite doors are very low maintenance. However, they still need semi-regular cleaning. The main question is how to clean composite doors using the right cleaning supplies so that you don’t cause damage.
We recommend only using mild detergents with warm water if the door is somewhat dirty. Most of the time, you can count on a simple wipe-down with a damp cloth to remove any debris. Our composite doors are all built with protective layers that prevent UV damage and weather-related abrasion. This technology is made specifically with low upkeep in mind. The use of overly strong cleaning materials, especially anything with bleach or acidic chemicals, may go on to impact the performance of this layer of high-value protection and lead to colour fading.
How to maintain your composite door
Contrary to popular belief, maintenance and cleaning are 2 different routines. To maintain your composite door, open it and line it with an old sheet underneath. Lubricate all of the moving parts with silicone spray, apart from the locking cylinder. To ensure your locking cylinder operates smoothly, use graphite powder for lubrication. Coat your key with graphite powder and insert it into the cylinder. Move it back and forth 10-15 times to distribute the lubricant thoroughly.
How often should you maintain your composite door?
Thanks to the components that come together to create a composite door, you’ll hardly notice the amount of maintenance needed. Their durability makes it so that most of the time you’ll only need to clean your door on an ad-hoc basis depending on your regular activities (i.e hiking and bringing dirt with your shoes!). At the very most, you’ll only have to clean it once a month with a wipe down. Your maintenance routine only needs to be done once every 6 months.

Here at Endurance, we don’t leave anything to chance. We’ve put together an aftercare page with a video guide on how to clean composite doors & carry out maintenance if you need further information.
