Problems with Composite Doors: Common Issues and Solutions

Ensuring your door remains functional and retains its appearance requires understanding the potential problems and knowing how to address them. Regular upkeep can prevent common issues like draughts caused by worn seals or problems shutting the door due to swollen materials. Additionally, questions often arise about the energy efficiency and thermal performance of composite doors, and how maintenance plays a role in preserving these benefits.

If you want to change your composite door because you’ve encountered too many problems consider upgrading to an aluminium door and frame. They do cost more but you won’t have warping or discolouration problems. They also look much more secure so might deter thieves.

Composite doors have become a favourable choice for many homeowners due to their robustness, security features, and aesthetically pleasing designs. While they’re engineered for durability and low maintenance, it’s important to recognise that, like any product, they may face issues over time. You might encounter challenges with sticky locking mechanisms, swelling due to weather conditions, fading or wear and tear on seals and gaskets.

Key Takeaways

• Regular maintenance enhances door performance and longevity.
• Understanding common issues can prevent future complications.
• Composite doors combine style, security, and energy efficiency.

Common Problems with Composite Doors

What are composite doors made of? A composite door is a type of door that combines various materials to provide enhanced durability, insulation, and aesthetic appeal. At its core, a composite door typically has a solid timber section, which lends strength and natural insulation, reducing the passage of cold air. This timber core is then surrounded by layers of other materials. Cheaper versions have a foam interior.

The most common additional material is uPVC, known for its versatility and weather resistance. In adverse weather conditions, uPVC maintains its appearance for an extended period, protecting the internal timber from damage like cracking, warping, and rotting. The combination of materials in a composite door ensures it remains functional and aesthetically pleasing for many years, requiring minimal maintenance.

Some composite doors also feature lamination layers, which add extra strength and contribute to better heat retention within the home, potentially leading to energy savings. Another option for the outer layer is GRP (Glass Reinforced Plastic), also known as fibreglass. GRP is highly resilient and adds to the overall robustness of the door.

However, like all types of doors, they can encounter specific issues over time due to temperature fluctuations (which are more extreme these days), humidity changes, and general wear and tear.

Dealing with Warping in Composite Doors

Warping can occur in composite doors, typically from exposure to direct sunlight causing the door materials to expand. To minimise warping, check for and replace any worn weather stripping and ensure that your door is properly shielded from extreme temperatures where possible.

Preventing Cracking in Composite Doors

Cracking may happen in the outer layers of a composite door due to extreme temperature changes or physical impact. To prevent this:

• Regularly inspect the door for any signs of damage.
• Apply a protective varnish or paint that is recommended for composite materials to guard against weather extremes.

Addressing Fading and Discolouration

Fading and discolouration are common issues with composite doors, often resulting from prolonged exposure to sunlight. To counteract fading:

• Clean your door with a gentle cleaning solution to remove any stains.
• Consider using a specialist composite door treatment. We recommend Polytrol which is available on Amazon to help maintain colour and protect against UV rays. We also recommend Door Restore on Amazon. Click here to take a look

Understanding Problems with Composite Door Locks

The locks on composite doors can sometimes become sticky or less secure over time. To ensure home security and maintain the easy function of your locking mechanism:

• Lubricate the locks regularly with a graphite-based product.
• Check the fitting of the door; it should not be too tight or too loose within the frame.

By undertaking routine maintenance and addressing these issues promptly, you can extend the life and performance of your composite front doors.

Regular Maintenance for Your Composite Door

Your composite door is designed to be low maintenance and highly durable, but to ensure it remains in the best condition and operates securely, a regular upkeep routine is essential. Here’s how you can maintain the different aspects of your door effectively.

Maintaining the Finish of Your Door

To keep the aesthetic appeal of your door, clean the surface periodically with a mild detergent such as liquid hand soap and warm water. Dry it with a soft, lint-free cloth. For deeper cleaning, use multi-surface plastic restorers to help protect the finish and keep it looking new.

Addressing Drafts and Air Leaks

Check the weather seals annually for any wear and tear that might cause draughts. Ensure the insulation is intact; if you have a draughty door, consider replacing the seals or engaging in minor hinge adjustments to improve the closure and reduce air leaks.

Repairing Scratches and Dents

In case of any scratches or dents, some composite doors can be fixed using touch-up pens or fillers specifically designed for UPVC or composite materials. Follow the manufacturer’s instructions to repair the affected area promptly to prevent further damage.

Ensuring Longevity with Proper Maintenance Tips

Regular lubrication of moving parts with products designed for self-lubricating bearings will ensure operational smoothness and reduce wear. Check the door’s alignment; if it’s off, realigning can be as straightforward as adjusting the hinges, which often enhances both the door’s function and its weatherproof integrity.

Remember, taking these steps will contribute significantly to the long-lasting performance and security of your composite door.

Optimising the Functionality and Appearance

Enhancing your composite door’s functionality and appearance involves addressing common mechanical problems and ensuring elements like glazing and colour remain pristine. Each aspect contributes to both the longevity and curb appeal of your front door.

Dealing with Swelling and Sticking Issues

Door swelling can be a common issue due to changes in humidity and weather. To combat swelling and sticking:

• Check for swelling around the door edges and sand down these areas slightly if necessary.
• Apply a thin layer of lubricant to sticky locks or components. A silicone-based lubricant works well for this. We recommend Holts available on Amazon.
• Ensure your door frame is free of debris and obstructions, which can hamper functionality.

Fixing Dropped Hinges and Handle Problems

Dropped hinges can cause a misalignment in your door, leading to further issues such as difficulty in securing the latch. For hinge and handle issues:

1. Adjust the screws on the hinges to realign the door with the frame.
2. If the handle is loose or difficult to turn, tighten the fittings or replace worn parts.

Enhancing Door Security Features

The security of your composite door is paramount. To enhance home security:

• Secure the locking mechanism by ensuring multi-point locks are fully engaged when closed.
• Check the lock cylinder for any signs of damage and replace if necessary to prevent snapping.

Maintaining Drainage and Addressing Water Ingress

Adequate drainage is crucial for preventing water damage and preserving the durability of exterior doors. To maintain drainage and address water ingress:

• Inspect and clear drainage holes to ensure they are not blocked by rainwater or debris.
• If water ingress is a problem, check the built-in drainage system and clear any obstructions in the door frame.
