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 latch, handle, hinge or ordinary running hardware no longer lines up or operates normally or the door closes poorly despite an otherwise sound visible opening. Causes: normal wear in hinges, latches or compatible mechanical hardware or loose fixings, minor alignment drift or ordinary timber movement.
The running rail may sit within a larger threshold assembly. This service does not alter structural openings, waterproofing or the building envelope. Explain any water-entry concern separately rather than treating a track repair as a diagnosis or remedy for it.
A replacement rail or insert needs the correct shape and dimensions. Provide the system reference where available. Similar-looking tracks may support different rollers, so a generic strip should not be assumed to be a suitable repair for every sliding door.
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.
