the latch, handle, hinge or ordinary running hardware no longer lines up or operates normally. Install a suitable ordinary supplied surface closer, make permitted adjustments or replace an unsuitable leaking unit within the agreed scope.
Signs: the door sags, rubs, sticks or has uneven gaps around the opening or the latch, handle, hinge or ordinary running hardware no longer lines up or operates normally. Causes: loose fixings, minor alignment drift or ordinary timber movement or local damage to an accessible component rather than an assumed structural defect.
Adjustment options vary by model. A suitable closer can be checked within its permitted range, but stiffness may also relate to hinges, alignment or seals. The enquiry should describe the movement rather than assume turning an adjustment screw is the complete repair.
The last part of the closing movement should be checked with the ordinary latch and frame. Increasing force is not a substitute for correcting an incompatible or misaligned latch. Any separate hinge or hardware repair needs agreement before extending the closer task.
Do not force the closer arm or alter adjustments beyond its instructions. Report a return of uncontrolled closing for review. Limits: Ordinary non-rated surface-mounted mechanical units only. No fire, smoke or egress certification, powered systems, structural reinforcement or specialist mechanisms.
