the latch, handle, hinge or ordinary running hardware no longer lines up or operates normally. Repair an accepted accessible rail or fit a compatible running insert or replacement section without changing the building envelope.
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: local damage to an accessible component rather than an assumed structural defect or loose fixings, minor alignment drift or ordinary timber movement.
Some systems accept a repair insert, while others do not. The insert must suit the profile, roller contact and available clearance. An improvised cover can change the panel height or movement, so compatibility should be established before materials are purchased.
Existing drainage features must not be obstructed by an ordinary repair. Show the complete threshold arrangement in the enquiry. Changes to a drainage or glazing system require the appropriate expertise and are not authorised simply because the damaged rail is nearby.
adjust and retain suitable existing hardware. replace an identified compatible component after measuring the existing item. Limits: Accessible non-structural running rails only. No threshold waterproofing alterations, drainage-system redesign, structural changes, major glazing or powered operators.
