Author: Richard Collins - Operations Director



Bifold doors are an excellent addition to any home and are available in a large range of designs and materials. However, to ensure they continue to function properly, there are a few things you need to know, including how to adjust them. This guide will detail when and how to adjust a patio door as well as general maintenance advice.

WHY DO BIFOLD DOORS NEED ADJUSTING?

Bifold doors are both functional and attractive. However, like any door, they will require maintenance. While adjustments will be more straightforward if you've opted for high-quality folding doors, it's handy to know some of the common reasons why bifold doors may need adjusting so you're better prepared in future.

WEAR AND TEAR

It's important to remember that just because your bifold doors need adjusting, it doesn't mean there is something wrong with them. Like a car, they experience wear and tear over time, especially if they are in constant use . This includes elements such as hinges, pivots and rollers.

CHANGE IN SEASON

Whilst high-quality doors made from aluminium or treated timber are unlikely to be affected, changes in temperature and extreme weather conditions such as strong wind and rain may affect some bifolds, particularly those made from uPVC.

LOCKING DIFFICULTIES

If your patio door won't close or lock, check the actual lock for any issues with the door in the open position. If you cannot find fault with the lock, your door may have fallen out of alignment with the locking keeps.

THE DOORS DON’T OPEN FULLY

If your Vufold wooden and composite bifold doors won't open fully, side-to-side adjustments need to be made. To make these, follow the steps below:

Step 1: open your doors as far as possible so you can access the top and bottom pivots.

Step 2: using a Philips screwdriver, move the doors from side to side, left or right. Please see the spacing guide below based on your door type.

Step 2: if you're using the Allen key provided, insert this into the pivots and carriers.

LOCKING ISSUES

As previously mentioned, locking issues are relatively simple to solve - especially with a high-quality door supplied by Vufold. If you're experiencing problems locking and unlocking your Ultra, Elite, Master, follow the steps below.

Step 1: eliminate the chance of it being an issue with the actual lock by opening the access door and pulling the handle upwards - if you can turn the key, the lock is operating normally and the problem is most likely a result of incorrect door adjustment.

Step 2: move the bifold doors over to the side of the lock jamb by altering the pivots until the gap is 4mm.

Step 3: if the lock works, gradually adjust them back the other way to a maximum of 6mm to 7mm or until the lock will not work.

Step 4: make a final small adjustment back to the lock jamb until operational.

Step 5: the height and side-to-side adjustments can be combined, so try altering the height up or down in the top pivot and intermediate carrier using an allen key or screwdriver. Adjust these until the lock works or to the default spacings in the above table.

HOW TO CARE FOR YOUR BIFOLD DOOR

Maintaining your bifold door is important as it ensures the longevity of your door and reduce the number of times you need to adjust. In this section, you will find maintenance advice on the main types of bifold door materials.

WOODEN BIFOLDS

Regular maintenance is important for wooden bifold doors, to ensure longevity. You should check the finish of your timber bifold every six months and recoat if necessary.

Vufold recommends using wood care milk - a wax-enriched finish enhancer designed to protect the original finish of your timber door which can lengthen time between refinishing.

Vufold also offers several care and finish kits to help maintain your bifold door and ensure it remains in warranty.

What are the benefits of wooden bifold doors?

Because wood is a natural material, it requires less manufacturing compared to synthetic materials like uPVC. Less manufacturing means less carbon dioxide, which lowers your carbon footprint. Wooden doors are biodegradable and can be responsibly sourced. Vufold creates high-quality wooden bifolds that are designed to last. We offer a 15-year guarantee on all our bifold doors.

ALUMINIUM BIFOLDS

Aluminium bifold doors are incredibly durable. As a result, they also require less maintenance than other materials. However, aim for the occasional cleaning routine to ensure your doors remain in top condition. Using a non-abrasive cloth and soapy water (avoid solvent-based cleaning products), wipe away any dirt on the frame and glass panels. You can also use a small brush and hoover to clear the tracks of any debris. Doing this regularly will ensure debris doesn't build up and stop the doors from opening or closing smoothly.

What are the benefits of aluminium bifold doors?

Aluminium weighs 67% less than steel yet carries a lot of its strength properties. This means that it can create lighter and easier-to-operate doors and windows. Aluminium allows for slim sightlines to be achieved for maximised views and can be made in a range of configurations without compromising on performance or security.
