Beaufort & ALUK Bifold Door Repair: Fixing Roller and Alignment Issues

If you have a set of bifold doors installed between five and fifteen years ago, there is a very high chance they are Beaufort or ALUK systems. These aluminium doors were industry favourites for their slim profiles and durability. However, even the best-engineered aluminium systems eventually feel the effects of time, heavy usage, and the British weather.

At Pro-Lock, we frequently see homeowners struggling with Beaufort doors that have become stiff, noisy, or impossible to lock. Because Beaufort was acquired by the ALUK Group, many homeowners are left wondering if parts are still available or if they need to fork out thousands for a full replacement.

The good news? Most of these issues are entirely repairable. This guide explores the common faults associated with Beaufort and ALUK systems and how our specialist repair service can restore them to like-new condition.

The Beaufort to ALUK Transition: Why It Matters

Before ALUK became a household name in the UK glazing industry, Beaufort was widely specified for slim, high-end aluminium bifold doors. As the system evolved into the ALUK product family, many homeowners were left with older Beaufort-branded doors that now sit within an ALUK lineage, with design links to later BSF70 and Visofold style systems.

That history matters when it comes to repairs. On external bifold doors, replacement rollers and hinges are not just chosen by appearance. The carriage design, wheel profile, fixing points, load rating, hinge geometry, and adjustment range all need to match the original system correctly. A door that started life as a Beaufort configuration may now require an ALUK-compatible or legacy-pattern part, and getting that wrong can create more drag, poor locking engagement, accelerated track wear, or even permanent damage to the aluminium frame.

While these doors are incredibly robust, their specific mechanical design, particularly the bottom-rolling carriages and integrated hinges, requires a specialist touch. You cannot simply swap these out with generic "off-the-shelf" hardware. Using the wrong parts or incorrect adjustment techniques can lead to permanent track damage, which is a far more expensive problem to solve.

Common Problems with Beaufort & ALUK Systems

Through years of specialising in ALUK bifold door maintenance, we have identified three recurring issues that affect these specific systems:

1. The "Dragging" Door (Panel Misalignment)

Aluminium is light, but the large double-glazed units inside the frames are incredibly heavy. Over time, the weight of the glass can cause the door panels to "drop" or shift slightly within the frame. This is known in the trade as "heeling and toeing" issues.

Symptoms of misalignment:

• The door drags along the bottom track, leaving scratches.

• You have to lift the handle or pull the door hard to get the locks to engage.

• Visible gaps appear at the top or bottom corners when the doors are closed.

2. Failed Roller Carriages

The Beaufort system relies on a set of rollers at the bottom of the main "slave" panels. These rollers use precision bearings designed to carry significant weight. However, once the internal bearings fail or the wheels flat-spot due to debris in the track, the door will feel like it’s "grinding" or "jumping."

✅ Pro-Lock Tip: If you hear a "clunk-clunk" sound when sliding your doors, your rollers have likely failed. Continuing to use them will eventually wear a groove into the aluminium track itself.

3. Hinge and Handle Resistance

Beaufort doors often feature high-security multi-point locking systems. If the door isn't perfectly aligned, the locking bolts won't line up with the keeps in the frame. This puts immense pressure on the handle and the internal gearbox. If the handle feels stiff, do not force it. Forcing the handle is the quickest way to snap the internal drive gear, leaving your home insecure.

Why Specialist Knowledge is Essential

Many general double-glazing companies or local handymen will look at a Beaufort or ALUK door and suggest a total replacement. They do this because they don't have access to the specific bifold door services required to source legacy parts or the technical training to realign these complex multi-panel systems.

At Pro-Lock, we take a different approach. We are specialists, not salesmen. We carry an extensive range of ALUK-compatible components, including the GreenteQ rollers and hinges specifically designed for the BSF70 systems.

Because Beaufort systems evolved into ALUK, correct part sourcing is one of the most important parts of the job. In plain English, that means we do not guess. We identify whether your external bifold door needs a true legacy Beaufort-pattern component, a current ALUK-compatible replacement, or a matched alternative that preserves alignment, smooth running, and locking performance.

Our repair process includes:

• Full Mechanical Audit: We check every hinge, roller, and lock to identify the root cause of the failure.

• Precision Realignment: We re-set the glass and adjust the hinges to ensure the doors are perfectly square.

• Part Replacement: We only use high-grade, compatible components that meet or exceed the original manufacturer's specifications.

• Track Restoration: We clean and lubricate the tracks using specialist silicone-based lubricants that don't attract dirt.

Transparent Pricing & Peace of Mind

We believe in total transparency. When you call us, you aren't just getting a "man with a van." You are getting a specialist assessment.

• Written Quotes: We provide a clear, written quote before any work begins.

• Warranty: All our repair work and replacement parts come with a comprehensive guarantee.

• No Pressure: We don't sell new doors, so we have no ulterior motive to tell you your doors are "unrepairable."
