uPVC Door Gearbox Replacement in Hertford
A uPVC door in Hertford had become difficult to lock because the door had dropped out of alignment.
The continued pressure caused the multipoint gearbox to fail. I replaced the faulty gearbox and realigned the door so the replacement mechanism operated correctly.
Work completed: 1 March 2025
Locks and Doors I Work On
The correct repair depends on the type of door, lock and fault. A problem that appears to be caused by the lock can sometimes be the result of door movement, worn components or poor alignment.
- Mortice deadlocks and sashlocks
- British Standard BS3621 locks
- Night latches and rim cylinders
- Euro cylinders and thumbturn cylinders
- TS007-rated and anti-snap security cylinders
- uPVC and composite door mechanisms
- Multipoint locking gearboxes and locking strips
- Door keeps and alignment problems
- Patio and French door locks
- Commercial aluminium door locks
- Mechanical code locks
- Communal entrance door hardware
Replacing a gearbox without correcting the door alignment can place the new mechanism under the same pressure that caused the original failure. I check how the complete door and locking system operate before recommending the repair.
