Common problems with composite front doors and how to fix them

As a popular, durable and reliable choice for front doors, composite doors have become more and more popular with homeowners. But, just like any other kind of wooden door or uPVC door, extra care and attention is a must to keep your composite door in excellent condition. Knowing the problems that can occur with composite doors, whether it’s the door frame, lock or glass, is the best way to avoid common issues.

In this guide, we look at some of the most common problems with composite front doors to help you identify and resolve issues swiftly and effectively, as well as prevent these problems from occurring or understand the maintenance that may be required when choosing a new door for your home.

Common problems and how to solve them

Composite doors are a much longer lasting solution than other types of front door and experience far fewer problems. However, it’s important to be aware of the problems you may encounter with a composite front door and how you can solve them or prevent them from happening.

Problem 1: Door won’t shut properly

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

Not only will an ill-fitting door affect the functioning of your front door, it will also let in draughts and outside weather, as well as making your property less secure. When looking for a new front door, it’s important to get the correct measurements and have the door fitted properly by a professional to prevent problems in the future.

In addition, 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.

Problem 2: Sticky lock

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.

Problem 3: Dropped hinges

Whether you’re living alone or you’ve got your whole family at home, your front door will be used multiple times every day. Self-lubricating bearings will keep your composite door in excellent condition for a long period of time. However, maintenance can help to prevent hinges from dropping which, in turn, makes your door easier to open without additional repairs or management required for plenty of daily use.

Problem 4: Drainage issues

By their nature, exterior doors are designed to weather the elements. For composite doors, timber doors and uPVC doors, that means an inbuilt drainage system. You can usually spot the drainage though a series of small slots and holes that allow rainwater to drain away, leaving your door in excellent condition and protecting your home.

However, over time, these holes can become blocked or dirty. Taking the time every six months or , when you spot a problem, can prevent drainage problems and ensure no floods occur in your entrance hall due to blockage issues.

Problem 5: Fading

As with any of the outdoor parts of your home, your doors are likely to fade and weather over time due to their exposure to the sun and other harsh weather condition. Over time, the effects of these corrosive elements can lead to a door that looks on the tired side. While you can’t just polish up or paint a composite door in the same way you might a timber door, there are options available to help you restore the door to pristine condition.

Whilst composite doors are less susceptible to wear and tear than other types of door, eventually they can begin to suffer. Multi-surface plastic restorers can help to revive your door’s look and feel while also protecting against future damage. In addition, scheduled re-application can ensure your door looks it’s best for as long as possible.

One of the biggest benefits of composite front doors is they do not require as much maintenance or care as a uPVC door or timber door and they are much longer lasting in comparison.

Problem 6: Draughts

While a solid front door is vital for the security of your home, it’s also crucial for keeping the warmth in and the cold out, or vice versa. Draughty doors can be a common problem, whether it’s due to a poor seal on the door itself or an obstruction causing a problem. Looking at your door in closer detail is the best way to find and diagnose draught issues. In many cases, you may be able to fix the draughts yourself with care and attention. In other cases, a professional may be able to help.


Do composite front doors expand in the heat?

Unlike wooden doors or uPVC doors, composite doors are not affected by prolonged exposure to heat or water or problems such as warping. These conditions can make some types of front door expand and contract and, eventually, the door will become warped making it difficult to open and close.

With a reinforced skin and strong core, composite doors are not subject to the same problems and will stay watertight and functioning well despite the varying weather conditions in the UK.

Can you repaint a composite front door?

If you’ve got the right materials and paint, it is possible to change the colour of your composite front door. It’s possible to paint your composite front door but you will need to prepare the surface properly to get a good finish. Due to the plastic outer layer of the door being glass reinforced plastic, it can be prone to chipping or flaking if it’s not done properly.

It can be very difficult to paint over a composite door so it is not usually recommended. A professional service can help to make sure it’s done properly and that the finish looks good.

If you notice scratches on the surface of the door, you can touch the door up to keep it looking pristine or, for a door that has faded, there are various products available to help restore the colour of the door. However, if you’ve decided you want to change the colour of the door completely, a new composite door may be the only option.

How long do composite front doors last?

A typical composite front door is built to last for around 30 years with the proper maintenance and good care. By knowing more about the problems we’ve listed above and preventing them from happening, your composite door can remain in perfect condition for its entire lifespan.
