Today I attended a rental property in Bentley, Doncaster, where the tenant couldn’t secure the front uPVC door. The locking mechanism had become increasingly difficult to operate before eventually failing.
Failed Lockmaster gearbox caused by poor alignment
After inspecting the door, I identified a failed Lockmaster gearbox. Poor door alignment had placed excessive strain on the multipoint locking mechanism.
When a uPVC door drops out of alignment, the locking points no longer engage smoothly with the keeps. Forcing the handle can eventually damage the gearbox.
Gearbox replacement and complete door adjustment
I replaced the faulty Lockmaster gearbox, adjusted the door hinges and realigned the keeps to ensure the locking points operated correctly.
The hinges had also become stiff, so I serviced and lubricated them. I then checked the door for draughts and made sure it closed securely against the frame.
Simply replacing the gearbox without correcting the alignment could have led to another premature failure.
Saving the landlord an unnecessary replacement
The completed repair restored smooth locking, eliminated draughts and left the tenant with a secure front door.
Importantly, the landlord avoided the expense of replacing an otherwise serviceable door.
Repair the faulty mechanism, correct the underlying problem and keep the existing door working properly.
