Do You Really Need New Bifold Doors? Here’s the Truth About Professional Repairs

Don’t replace, repair! 🛠️

If your external bifold doors are dragging across the floor, catching on the frame, or refusing to lock properly, your first thought might be that they’ve reached the end of their life. You might even have had a general builder or a door salesman tell you that "they’re past it" and you need a full replacement.

In the vast majority of cases, this simply isn't true.

At Pro-Lock, we specialise exclusively in the restoration and mechanical repair of external bifold doors. Whether yours are aluminium, uPVC, timber, or hybrid systems, these are complex pieces of engineering that require specialist calibration, not a skip.

In this guide, we reveal the truth about bifold door longevity and why a specialist repair is almost always the smarter, more cost-effective choice.

1. The Cost Comparison: Repair vs. Replacement

Replacing external bifold doors is usually far more disruptive and expensive than many homeowners expect. It often involves far more than just the doors themselves, with additional installation work, associated surveys, and the upheaval of removing a complete system.

In contrast, a professional mechanical overhaul and realignment from Pro-Lock is often a far more practical and cost-effective route. Our goal is to prolong the life of your existing doors and restore smooth operation wherever repair remains the sensible option.

✅ Cost-Saving: Professional repairs are often significantly more economical than full replacement. ✅ Sustainability: Reduce waste by keeping high-quality materials out of the landfill. ✅ Efficiency: Most repairs are completed within a few hours, not days.

Important: We do not provide fixed pricing or guesswork online. Every bifold door system is different, so pricing is only provided after an assessment visit and a proper inspection of the fault, hardware, alignment, and overall condition.

2. Why Your Doors Are Dragging (And How We Fix It)

If you find yourself using two hands to "heave" your doors across the track, the issue is rarely the door panels themselves. It is almost always a failure of the bottom rollers or a misalignment of the track.

Over time, dirt and debris can act like sandpaper on the nylon or stainless steel rollers. Eventually, the bearings fail, causing the door to "drop" and drag.

Our Solution: Restore and Realign

We don't just "spray some WD-40" and hope for the best. Our specialist process includes:

• Component Replacement: We carry a vast range of high-quality rollers and hinges for leading systems like Visofold, Schuco, and Origin.

• Track Cleaning & Lubrication: Removing the abrasive grit that destroys hardware.

• Height Adjustment: Re-setting the rollers to the exact millimetre to ensure the weight is distributed evenly across the carriage.

3. The "Won't Lock" Myth: It’s Often "Toe and Heeling"

One of the most common reasons homeowners think they need new doors is because the locking mechanism has "failed." The handle feels stiff, the key won't turn, or the shootbolts don't line up with the keeps in the frame.

In 9 out of 10 cases, the lock isn't broken, the door is simply out of square. This is solved through a technical process called "Toe and Heeling."

Bifold glass is incredibly heavy. If the glass isn't braced correctly within the frame using internal packers, the door panel will "sag" or "kite," pulling the locking points out of alignment.

✅ Professional Re-setting: We remove the beads and re-pack the glass to "lift" the door back into its original factory shape. ✅ Shootbolt Relief: By realigning the frame, we remove the pressure on the gearbox, preventing your handle from snapping. ✅ Security Upgrades: While we’re there, we can upgrade your cylinders to 3-star anti-snap locks for ultimate peace of mind.

4. Eliminating Draughts and Whistling

Are your doors letting in a cold breeze? Over years of exposure to the British weather, rubber seals (gaskets) can shrink, perish, or become trapped in the hinges.

We provide a comprehensive seal replacement service for external bifold doors. By installing fresh, high-compression gaskets, we can eliminate draughts and improve the thermal efficiency of your home instantly.

Please note: While we are experts in external door weather-proofing, we do not service internal wardrobe or room-divider bifolds, as these do not use the same heavy-duty weather-sealing technology.

5. The Pro-Lock Advantage: Unbiased, Specialist Advice

This is our most important USP: We do not sell new doors.

Most double-glazing companies are set up to sell and install. If they come to look at a "broken" door, their incentive is to tell you it’s unfixable so they can sell you a new one.

At Pro-Lock, our entire business model is built on restoration. Because we don't manufacture or install new systems, our advice is 100% unbiased. If your door can be saved, we will save it.
