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: normal wear in hinges, latches or compatible mechanical hardware or local damage to an accessible component rather than an assumed structural defect.
The agreed repair is checked with the accepted panel and its hardware. Catching at one point can differ from resistance along the entire run. Any roller or alignment work should be listed separately so a track-only quote does not imply every movement problem will disappear.
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.
Repair an accepted accessible rail or fit a compatible running insert or replacement section without changing the building envelope. Limits: Accessible non-structural running rails only. No threshold waterproofing alterations, drainage-system redesign, structural changes, major glazing or powered operators.
