Expert Automatic Door Repair in St Albans
Business owners in St Albans know that a broken shopfront door kills trade. We provide rapid, industrial-grade repairs. As independent specialists, we work on all major brands including Dorma, Record, Geze, and Assa Abloy.
Control Board Logic Repair
We diagnose faults in the Microprocessor Control Unit (PCB). Our St Albans engineers can often reset factory parameters or update firmware rather than swapping expensive boards.
Telescopic Door Alignment
Telescopic doors in St Albans require precise belt synchronization. We align the slow and fast leaves to prevent jamming and ensure maximum opening width.
DDA Low Energy Systems
Make your St Albans shop accessible. We install 'Low Energy' push pads for wheelchair users, complying with the Equality Act (DDA).
Brushless DC Motor Diagnostics
The drive unit is the heart of your system. In St Albans, we troubleshoot high-torque DC motors, replacing worn carbon brushes or faulty encoders to restore silent operation.
Glass Alignment & Anti-Rise
Heavy doors drop over time. We adjust eccentric rollers and anti-rise bolts to lift the door leaf, preventing it from scraping the floor in your St Albans premises.
