Beaufort bifold door repair.
We regularly assess Beaufort systems for difficult running, worn rollers, threshold faults, dropped panels, and shootbolts or locks that will not engage cleanly.
Positioning
Beaufort is an older aluminium bifold system that is now part of AluK — Beaufort Secure Design was acquired and the range was rebranded as AluK (GB) Limited in 2013. Because of that lineage, replacement parts for these older doorsets can still be sourced, and we are able to source them. That matters where a doorset has been treated as obsolete: an older Beaufort door does not have to mean a new door. Less manufacturer-level technical material exists for the Beaufort name than for the current AluK ranges, so the assessment establishes the actual hardware on the doorset rather than assuming it from the brand.
Beaufort bogie wheels, thresholds and intermediate shootbolts — what we see most on Beaufort doorsets
The Beaufort material describes a distinctive running arrangement: four-wheel bogie assemblies travelling on twin stainless-steel tracks, with a defined maximum panel weight. If the doors become heavy or uneven, we check the bogie assemblies, both tracks, panel alignment and the load transferred through the frame, rather than assuming a single conventional roller has simply worn.
Threshold selection is particularly important on Beaufort doors. The published range includes a standard weather-rated threshold, 34mm low and ramped low thresholds, and a 22mm internal room-divider threshold. A threshold that is unsuitable for the exposure, or a drainage route that is obstructed, can present as water ingress or catching at the bottom of the panel.
The intermediate panels use pop-out T-handles operating top and bottom locking bolts, while the traffic door uses a lever handle and multi-point locking. A locking fault therefore needs to be traced to the relevant panel and mechanism rather than described simply as a failed "bifold lock". We check the locking-bolt travel, keeps, hinges and panel position together, and verify the actual section and part numbers before quoting.
How the assessment supports the right repair.
The assessment follows nine connected stages, from reviewing the doorset’s history and measuring its condition to checking operation, components and manufacturer tolerances. The findings give us a clear basis for an accurate quotation.
We start with the background and history of the doorset, then take extensive measurements for distortion and check the frame for square and twist. We test operation under load, check drainage paths, and inspect glazing, gaskets and packers. Where parts are involved, components and part numbers are verified against the manufacturer, and every measurement and observation is cross-checked against the manufacturer's recommended tolerances. After that cross-check, we provide an accurate quotation based on the assessment findings.
The full process is set out stage by stage on our How it works page.
Open the assessment processWhat we assess
- Fractured or damaged hinges
- Broken, worn, or disconnected rollers
- Dragging, dropped, or misaligned panels
- Panels catching the threshold or header
- Difficult closing or locking
- Faulty locks, cylinders, handles, keeps, tracks, guides, and seals
How the assessment supports lasting performance
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.
An experienced engineer assesses the complete bifold doorset, talks you through the findings on site, and provides a written report with a quotation for any recommended repairs.
The findings are followed by a comprehensive report and itemised quotation by email, with repairs arranged separately. No repair work is carried out during the assessment.
The £79 fee covers a professional bifold-door assessment of the complete doorset. £79 professional assessment, credited against any repair, or refunded if we cannot quote. 12 month warranty on completed repair work.
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.
Warranty
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.
