uPVC Door Mechanism Repair
The multipoint mechanism is the long metal strip inside a uPVC door's edge that throws hooks, rollers and bolts into the frame. When it fails, the door may not lock at all. We source and fit the right replacement.
Signs the mechanism has failed
- The handle moves but the hooks or bolts don't
- There's a grinding or clicking noise when lifting the handle
- The door locks but won't unlock
- Parts of the mechanism have visibly snapped
How we solve it
Your locksmith will remove and identify the mechanism by its backset, centres and faceplate. Often only the centre gearbox needs replacing. Otherwise a full matching or universal replacement is fitted.
