Expert Automatic Door Repair in Hatfield
Business owners in Hatfield 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.
Finger Guard Compliance
For swing doors in Hatfield, finger entrapment is a major liability. We inspect and replace fabric roller guards at the hinge line to meet BS EN 16005 regulations.
Planetary Gearbox Renewal
Grinding noises usually mean nylon gear fatigue. Instead of replacing the whole operator, we rebuild the planetary gearbox on-site in Hatfield, saving you thousands.
Fire Alarm Interface
We verify the link between your door and the building fire panel. In Hatfield, the door must 'Fail Safe' (open fully) immediately when the alarm sounds.
Telescopic Door Alignment
Telescopic doors in Hatfield require precise belt synchronization. We align the slow and fast leaves to prevent jamming and ensure maximum opening width.
Brushless DC Motor Diagnostics
The drive unit is the heart of your system. In Hatfield, we troubleshoot high-torque DC motors, replacing worn carbon brushes or faulty encoders to restore silent operation.
