Pro-Lock · Supported systems
Bifold door brands we repair.
Pro-Lock repairs major aluminium, uPVC, timber, and hybrid bifold door systems, including discontinued systems where compatible parts can be sourced. We work from the fault in front of us, with the aim of a long-term repair rather than a short-term fix.
A repair-first view
The brand helps identify the system. The assessment tells us what it needs.
We do not supply or fit new doors, so our advice stays focused on restoring the existing one wherever that is sensible.
No need to know the brand
You do not need to identify your doorset first.
You do not need to identify your doorset before getting in touch. Many bifold doors are unbranded or contain a combination of components from different manufacturers. Identifying the system, cross-checking component and part availability, and sourcing suitable parts through our established European network of suppliers is our job. Pro-Lock regularly repairs bifold door systems that other repairers have classed as obsolete, where a suitable repair route can be identified.
Major brands and ranges
Systems we can assess.
Every manufacturer has variations between ranges, ages, and hardware revisions. We confirm compatibility before carrying out a repair.

Siegenia Aubi
Siegenia-Aubi is a German hardware manufacturer whose folding gear is fitted into uPVC, timber, and aluminium bifold doorsets from many profile suppliers. The hardware itself is often the useful identification point rather than a badge on the doorset, so Pro-Lock inspects the rollers, hinges, locking gear, and threshold before confirming the fitted generation.

Materials and systems
The material matters to the repair.

Slim-profile systems where rollers, tracks, hinges, alignment, and locks need to work together.
uPVC
Systems where adjustment, rollers, seals, handles, and locking points can all affect closure and security.
Timber
Timber bifold doorsets assessed for movement, fit, hardware, alignment, and weather sealing.
Hybrid
Doorsets combining materials, where the interaction between frame, panels, hardware, and seals is part of the diagnosis.
All work carried out is backed by our market-leading 12 month warranty, covering our workmanship and any parts supplied and fitted as part of the repair where applicable.
