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 closes poorly despite an otherwise sound visible opening or the door sags, rubs, sticks or has uneven gaps around the opening. Causes: loose fixings, minor alignment drift or ordinary timber movement or local damage to an accessible component rather than an assumed structural defect.
Show the arm’s path and surrounding trim or walls. The door must have the clearances required by the selected arrangement. Moving the arm to avoid an obstruction without following the maker’s instructions can create a different problem rather than a suitable fit.
A closer needs to suit the door it controls. Provide leaf dimensions and product weight where available. An oversized or undersized unit should not be compensated for with extreme adjustment, and unsupported heavy doors need a different handling assessment.
adjust and retain suitable existing hardware. replace an identified compatible component after measuring the existing item. Limits: Ordinary non-rated surface-mounted mechanical units only. No fire, smoke or egress certification, powered systems, structural reinforcement or specialist mechanisms.
