Hi, I’m Matt, the owner here at Pro-Lock. If you’ve landed on this page, chances are you’re currently wrestling with a bifold door that just won’t behave. Maybe it’s a bifold door dragging on the floor, or perhaps the bifold handle is stuck, leaving your home vulnerable or your garden inaccessible.

I see it every single day: homeowners who have been told by "general" window fitters that their expensive doors are past their sell-by date and need a full replacement. Stop right there.

At Pro-Lock, we live by a simple rule: Don’t replace, repair! 🛠️

Most bifold issues: even the ones that look terminal: are actually mechanical failures or alignment problems that can be expertly restored. Whether your doors are aluminium, uPVC, or timber, we specialise in the complex mechanics that keep them running.

Note: We specialise exclusively in external bifold doors. We do not service internal doors, such as wardrobe or cupboard bifolds.

Why is your Bifold Door Dragging on the Floor?

When you feel that sickening "thud" or hear a scrape as you slide your doors, it’s a clear sign of a system under stress. A bifold door dragging on the floor isn't just an annoyance; it's a mechanical emergency.

The Root Causes

Dropped Panels: Over time, the weight of the double-glazed units can cause the panels to "drop" or go out of square. This is common in aluminium systems where the "toe and healing" (internal packing of the glass) has shifted.
Worn Rollers: Your bifold doors weigh a significant amount. This entire weight sits on the bottom rollers. If these bearings collapse, the bottom of the bifold door catching on the track is the first symptom.
Track Obstruction or Damage: Small stones or debris in the track can cause the rollers to jump, leading to misalignment.

How We Restore It

We don't just "give it a shove" and hope for the best. Our specialist technicians perform a comprehensive re-alignment and re-set.

✅ Precision Adjustment: We recalibrate the hinges and pivot points to millimetre accuracy.
✅ Component Replacement: If the rollers are shot, we replace them with high-quality, genuine parts from brands like Origin, Aluk, and Alutech.
✅ Track Restoration: We clean and lubricate the tracks to ensure a "one-finger" operation.

The "Stuck Handle" Nightmare: When it Won't Lock

There’s nothing quite as stressful as a bifold handle stuck when you’re trying to lock up for the night. If your bifold door won't lock properly, it’s usually down to one of two things: alignment or the multi-point locking mechanism itself.

Why the Handle Jammed

Bifolds use a complex series of rods and shoot-bolts. If the panels are even 2mm out of alignment, those bolts won't line up with the keeps in the frame. When you force the handle to try and engage the lock, you risk snapping the internal gearbox.

Our Solution

Non-Destructive Entry: If you're locked out (or locked in), we can open the door without damaging the frame or the glass.
Gearbox Replacement: We carry a wide range of replacement lock gearboxes and cylinders. We can often upgrade your security at the same time with anti-snap cylinders.
Peace of Mind: Once we’ve repaired the lock, we realign the doors to ensure the locking points glide into place with zero resistance.

Repair vs. Replacement: The Honest Truth

Why commit to the cost and disruption of new doors when a specialist repair is often significantly more economical?

Feature	Repair (Pro-Lock)	Full Replacement
Cost	Typically far more cost-effective	Usually a much higher overall outlay
Time	Often completed within a single visit	Commonly more involved, with lead times
Disruption	Minimal (No mess)	High (Building work/re-plastering)
Outcome	Restored to original performance	New product (often unnecessary)
Warranty	All repairs guaranteed	Standard product warranty

We are not door salesmen. We don’t sell new doors. This means our advice is 100% unbiased. Our goal is to prolong the life of your existing doors and restore them to their former glory.
