Expert Bifold Door Repairs in Sevenoaks and Across West Kent
Pro-Lock provides specialist bifold door repair services in Sevenoaks and across west Kent, covering the town and its surrounding villages and rural communities throughout the district.
Unlike locksmith-based services that focus on replacing individual components, our engineers take a whole-door approach, diagnosing and addressing the underlying cause of the fault rather than the symptom. Payment is only taken on completion.
Bifold Door Problems We Repair in Sevenoaks
One of the most common calls we receive from Sevenoaks homeowners is a bifold door lock that keeps failing or a door that will not close properly. In many cases the lock is not the problem. Bifold door locks fail because the door has dropped out of alignment, putting stress on the shootbolt mechanism until it breaks. Replacing the lock without correcting the alignment means the same fault will return.
Our engineers diagnose and repair the root cause across the full range of bifold door faults in aluminium, uPVC, and timber systems, including:
-
Worn rollers, trolleys, and tracks causing doors to stick, scrape, or come off their guides
-
Misaligned panels resulting in gaps, draughts, and uneven closures, including toe and heel correction
-
Bifold door lock failure caused by misalignment where the shootbolt mechanism is under stress and the top and bottom rods will not engage correctly
-
Faulty handles, hinges, and magnet catches where wear or misalignment is the underlying cause
-
Perished seals and gaskets letting in draughts, water, or noise
-
Bifold doors that won't close, fold properly, or lock securely
-
Larger and more complex bifold installations including barn conversions and multi-panel systems
-
Doors overdue for general servicing and lubrication
Addressing the root cause rather than replacing individual parts means your doors stay working and you avoid the cycle of repeat callouts.
How the Process Works
Step 1. Professional Assessment, £79 Fully Refundable
One of our engineers will visit your Sevenoaks property and carry out a thorough inspection of all panels, rollers, tracks, hinges, seals, and locking mechanisms, including checking toe and heel alignment and frame fixings. This whole-door assessment is what allows us to identify why a lock, handle, or roller has failed, not just that it has failed. The assessment fee is £79, fully refundable against any repair you choose to go ahead with. You only pay for the work you actually need, with a clear written quote before anything is confirmed.
Step 2. Clear Written Quote
Following the assessment you will receive a written quotation listing essential repairs separately from any optional improvements. You are free to approve, decline, or ask questions before any work is booked.
Step 3. Repair Appointment
Once you approve the quote we schedule a convenient appointment. Our engineers carry out all agreed repairs using quality replacement parts, including realignment and servicing of misaligned or dropped panels, roller, hinge, handle, and gasket replacement, lock and mechanism adjustment, and sourcing of hard-to-find or discontinued parts through our trusted UK and European supplier network.
Step 4. Payment on Completion
Payment is only taken once the work has been completed to your satisfaction. There are no deposits, no hidden charges, and no payment until you are happy with the result.

Why Choose Pro-Lock for Bifold Door Repairs in Sevenoaks?
With over 20 years of experience in bifold door repair and the locksmith industry, we understand how bifold door locks, handles, and mechanisms fail and more importantly why they fail. A locksmith can replace a broken lock. Our engineers identify whether misalignment, dropped panels, or worn rollers are causing the lock to fail in the first place, correct those issues, and then repair or replace the hardware. This whole-door approach is what breaks the cycle of repeat failures and avoids unnecessary ongoing repair costs.

Which bifold door brands do you repair in Sevenoaks?

My bifold door lock keeps failing. Do I just need a new lock?
Not necessarily. In most cases a repeatedly failing bifold door lock is caused by misalignment rather than a faulty lock itself. When a door drops out of alignment it puts stress on the shootbolt mechanism until it breaks. Replacing the lock without correcting the alignment means the same fault will return. Our whole-door assessment identifies the root cause so the repair lasts.
Is there a call-out charge?
The £79 assessment fee covers the engineer's visit, inspection, and written quotation. It is fully refundable against any repair you proceed with, so if you go ahead with the work you are not paying for the assessment separately.
