Expert Automatic Door Repair in Hersham
Business owners in Hersham 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.
Threshold Track Cleaning
Grit in the floor guide destroys rollers. We deep clean the sub-floor track and replace stainless steel inserts to ensure gliding operation in Hersham.
Manual Breakout Testing
For sliding doors on escape routes, we test the 'Green Box' breakout. We ensure Hersham staff can push the doors open manually in an emergency.
Pressure Mat Servicing
For older Hersham doors, we replace worn rubber pressure mats, eliminating dead spots and ensuring reliable activation.
Brushless DC Motor Diagnostics
The drive unit is the heart of your system. In Hersham, we troubleshoot high-torque DC motors, replacing worn carbon brushes or faulty encoders to restore silent operation.
Swing Door Operator Tuning
We adjust latching action and backcheck on swing operators (like Record DFA 127). This ensures your Hersham door closes securely against wind pressure.
