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 closes poorly despite an otherwise sound visible opening or the door sags, rubs, sticks or has uneven gaps around the opening. Causes: local damage to an accessible component rather than an assumed structural defect or loose fixings, minor alignment drift or ordinary timber movement.
Show the points where movement catches as well as the full track. Local damage may have a different repair option from extensive wear. Photographs help describe the problem but cannot establish that the track, rather than the rollers or frame, is the only cause.
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.
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.
