DOOR ALIGNMENT & LOCKING
Help with UPVC and composite doors that have dropped, catch on the frame or become difficult to lock in Cambridge and surrounding areas.
Door movement can place extra pressure on a multipoint locking system. If a door needs pushing, pulling or lifting before it locks, the alignment should be checked rather than repeatedly forcing the handle.
The locking points may be meeting the keeps incorrectly, increasing resistance when the handle is lifted.
A door that rubs or catches may have moved out of its correct position.
If the mechanism works with the door open but becomes difficult when closed, alignment is an important possibility to investigate.
Continuing to force a misaligned door can put unnecessary load on the gearbox and multipoint mechanism. Correcting the underlying alignment issue may prevent further damage where the mechanism itself is still serviceable.
