Engineering Process
- 1
Compliance Testing
Every commercial repair concludes with a rigorous stress test to guarantee smooth operation, building security, and compliance with local fire regulations.
- 2
Commercial Hardware Sourcing
We carry heavily stocked vans with leading trade parts including Dorma, Geze, Axim, and Alpro mechanisms to ensure a first-time fix and minimal business disruption.
- 3
Precision Engineering
We safely extract the damaged hardware, install the commercial-grade replacements, and recalibrate the door's tension and closing sweep speeds.
- 4
Rapid Trade Diagnostics
Our engineers arrive equipped to assess the mechanical fault on your door—whether it's a blown Dorma floor spring, a slammed Axim closer, or jammed Adams Rite locks.
Common Trade Diagnostic Faults
Industrial units and warehouses in Marylebone frequently require immediate replacement of blown floor springs.
- Adams Rite commercial locks failing to engage properly, leaving the retail premises unsecured overnight.
- Glass office doors violently slamming shut causing shatter risks to employees and clients.
- Heavy metal industrial doors dropping on their hinges, preventing the crash bar from locking.
- Shopfront floor springs leaking black hydraulic fluid, indicating a blown internal seal.
