Common Trade Diagnostic Faults
Offices and industrial units in Northwood regularly need rapid fixes for slamming Dorma closers.
- Aluminium shopfront doors scraping heavily on the floor, making them difficult for clients to operate.
- Commercial glass doors violently slamming shut, posing a severe liability risk to staff and customers.
- Floor springs leaking hydraulic fluid, indicating a blown internal seal that requires urgent extraction.
- Automatic swing operators making grinding noises or stopping mid-cycle due to motor strain.
- Automatic doors remaining stuck open or failing to detect pedestrians due to faulty motion sensors.
- Commercial locks failing to engage properly, leaving business premises unsecured after hours.
