The specialist difference
Pro-Lock is a bifold door repair specialist with extensive experience working with aluminium, uPVC, timber and hybrid bifold doorsets. That includes major systems from Origin, Vufold, and Schüco, as well as timber doorsets manufactured by Henderson, Brio, and Centor.
Each material behaves differently in use. Aluminium systems are often affected by running gear and alignment; uPVC systems by rollers, seals, and locking adjustments; timber doorsets by movement, fit, and hardware; and hybrid systems by the interaction between those materials. We assess the complete doorset so the repair matches the system.
These are precision systems with several connected moving parts. A door may feel like it has a lock problem when the real cause is a worn roller or a panel that has dropped. Our job is to understand the complete doorset, find the underlying fault, and restore it properly.
Seasonal changes in temperature, sunlight, and weather can make bifold door panels and frames expand and contract. That is why a temporary adjustment may not be enough; we look for the underlying cause and aim to leave you with a long-term repair.
That specialist focus means practical, repair-first advice. We explain what your existing door needs and how the recommended work can restore its operation. If replacement is genuinely the sensible option, we will explain why.
Pro-Lock assesses the complete doorset and recommends repairs with the aim of returning it to operation as intended by the manufacturer. Understanding how the panels, running gear, seals, locks and frame work together helps reduce unnecessary strain on connected components, support reliable operation and minimise repeat repairs over the long term.
A thorough first step
We know you want the issue resolved as soon as possible. The assessment gives our experienced engineer time to understand what is affecting your doorset and recommend a repair that fits the problem.
Photos can help us understand the symptoms, but they can’t show how the panels, hinges, rollers, tracks, seals, locks and frame are working together. An experienced engineer assesses the complete doorset and discusses the findings with you on-site. We don’t carry out repair work during the assessment; you’ll receive a written report and quotation afterwards. The £79 assessment fee is credited against any repair, or refunded if we cannot quote.
A bifold doorset works as a connected system. By checking how the panels, hinges, rollers, tracks, seals, locks and frame relate to one another, the engineer can understand what is affecting movement and operation and shape a quotation around the repair your doorset needs.
Addressing the cause helps reduce unnecessary strain on connected components, supports smoother day-to-day operation and can reduce the chance of the same fault returning. Taking the time to assess the whole system supports more dependable use of your existing doorset over the long term.

The doors we work on
From anthracite aluminium and timber to wide exterior doorsets, we work on the existing doors that keep your home connected to the garden. A thorough assessment focuses on what your existing doorset needs and whether it can be repaired.
Repair-first advice
Pro-Lock does not supply or fit new bifold doors. That matters: our recommendation is based on the condition of your existing door, not on selling you a replacement.
We will always look for a sensible repair first. When a part needs replacing, we explain why. When adjustment or servicing is enough, we will tell you that too.
Detailed bifold door services
A lasting repair starts with understanding how the complete doorset works together. The assessment helps us identify which parts are affecting operation and recommend work that supports smooth, reliable use.
Assess hinge damage and wear where panels are folding, sitting, or moving incorrectly.
Trace heavy, noisy, or failing running gear and check whether suitable parts are available.
Address movement and alignment faults as part of the complete doorset, not as an isolated adjustment.
Investigate panels catching at the threshold or header, including track, frame, and panel position.
Assess doors that are difficult to close or lock before force creates further damage.
Repair or replace faulty security and closure hardware where the right part can be sourced.
Assess damaged or worn tracks, guides, magnets, catches, and related working hardware.
Trace draughts, rattles, and poor contact through seals, panel position, and closure.
Toe and heel is one important area checked when appropriate: manufacturer-specific glazing packers positioned at diagonally opposite corners of the glass help keep the sash square and level, supporting smooth movement and, where relevant, lock alignment.
A complete doorset overhaul is a repair option used when frame distortion is beyond the manufacturer’s tolerances and/or panel realignment cannot compensate for the degree of frame distortion. It can include structural repairs where the frame is distorted, but not every complete overhaul requires structural frame repair.

03
We can work with original, obsolete, or OEM manufacturer parts where they are available and appropriate for the repair.

Customer feedback
Clear communication, careful work, and a proper diagnosis are part of every Pro-Lock repair.
“Exemplary customer service and quality of work. Pro-Lock diagnosed the problem urgently and repaired it with an OEM part. Communication was prompt, and the professionalism, value, and specialist knowledge were excellent.”
“Punctual, clear in their explanations, and confident in their diagnosis. The problem was resolved.”
“Pro-Lock serviced and updated our extensive bifold doors, which had been jamming and were not closing properly. The workmanship was skilled and tidy, and we strongly recommend them.”
“I called Matt when I identified my bifold doors weren’t working as well as they had been. At the initial appointment, he honestly advised what work was needed, which I agreed to following a detailed quotation. Another Matthew undertook the work to a very high standard. He was very professional and thorough in his work, and my doors now glide open and closed. I can thoroughly recommend this company.”
“The traffic door on our Kloeber bifolds had gone out of alignment and was no longer lining up. The Pro-Lock engineer arrived as arranged, diagnosed the problem straight away and had it fixed in about 25 minutes. The door now opens, closes and locks perfectly. He was professional and knowledgeable, with no upselling, just the repair we needed at a fair price. I wouldn’t hesitate to call Pro-Lock again.”
