Engineering Process
- 1
Specialist Commercial Sourcing
Our dynamic response vehicles house authentic parts from Record, FAAC, Axim, and Dorma to enable single-visit commercial remediation.
- 2
Precision Calibrations
We physically source new machinery modules, implement hardware profiles, and precisely scale closing cycles and detection radii.
- 3
Compliance Evaluation Tests
Every automated system repair concludes with an exhaustive check to enforce absolute building compliance with UK BS EN 16005 metrics.
- 4
Automated System Triage
Our trade engineers deploy rapidly to map sensor connectivity, power lines, and structural clearway alignments to pinpoint operational failures.

Common Trade Diagnostic Faults
Busy high-street shops in Welwyn Garden City often require structural realignment of aluminium doors.
- Break-out system limit switches misaligned, halting high-traffic entrance cycles altogether.
- Hydraulic door closures or floor springs discharging dangerous oily fluid indicators of severe internal breakdown.
- Automatic commercial doors lingering open or halting midway through sliding cycles due to internal logical loops.
- Concealed transom systems grinding and binding because internal gear spindles dropped beneath standard clearance parameters.
