Tools needed

  • Screwdriver set
  • Stiff wire bristle brush
  • Vacuum

Materials needed

  • Professional silicone lubricant spray
  • Replacement sliding door roller wheels (if worn)

Step-by-step

  1. 1

    Vacuum the track, then scrub out grit with a stiff wire brush.

  2. 2

    Locate the adjustment screws at the bottom edge of the door.

  3. 3

    Lift the door off its track if the rollers need replacing, and swap them.

  4. 4

    Spray silicone lubricant along the track and rollers (avoid oily grease that attracts dirt).

  5. 5

    Reseat the door and fine-tune the height screws until it glides and latches evenly.

Common mistakes

  • • Using petroleum grease that collects dirt and gums the track
  • • Forcing a stuck door and bending the track

Maintenance & next steps

Vacuum the track and reapply silicone a couple of times a year.

When to call a professional

For a cracked frame, shattered glass, or a severely bent track.
