Fix sticking, scraping or wobbly sliding wardrobe doors by adjusting the roller screws and cleaning the tracks.
AD-01Clear the doors and check how they runTake clothes off any hangers near the doors so nothing gets in the way. Slide each door fully open and closed once, watching and listening for where it catches, scrapes or drags. Wipe dust off the top and bottom tracks with a dry cloth so you can see the rollers and guides clearly.
AD-02Work out what's wrongScraping along the floor or catching at one end usually means the door needs a height adjustment. Wobbling or rubbing the frame at the top means the top roller needs realigning. If a door jumps out of its bottom channel, the floor guide is probably worn or knocked out of place.
AD-03Find the adjustment screwsMost sliding wardrobe doors have a small adjustment screw on each roller carriage at the top, reached from the top edge of the door or behind a small plastic cap. Some older wardrobes adjust at the bottom instead. Check any manual you have, as the exact position varies by make.
AD-04Adjust the door heightTurn the adjustment screw clockwise to raise the door, anticlockwise to lower it. Make small quarter-turns, sliding the door after each one, until there's an even 3-5mm gap along the bottom. Adjust both rollers on the same door by the same amount so it doesn't tilt.
AD-05Level the door side to sideHold a spirit level against the door's leading edge to check it hangs straight. If one side sits lower, adjust just that roller until the door is level and slides past its neighbour without scraping.
AD-06Clean and lubricate the tracksVacuum grit and fluff out of the top and bottom tracks, then wipe them dry. Spray a light coat of silicone lubricant along both tracks and over the rollers, then slide each door back and forth a few times to work it in. Avoid oil-based lubricants, as they attract dust and turn gritty.
AD-07Check the floor guideLook at the small plastic or metal guide block fixed to the floor between the doors. Check it's screwed down tight and sitting centrally in the door's bottom channel. Tighten any loose screws or reposition it if a door keeps jumping the track.
AD-08Test and fine-tuneSlide each door fully open and closed several times, checking for smooth movement, even gaps and no scraping. Make small further tweaks to the roller screws if needed. A well-adjusted door should close with a light push and sit flush with the frame.
AD-09Tidy upWipe any excess lubricant off the tracks and door edges. Put clothes and shelves back once you're happy the doors run smoothly. Keep the screwdriver handy, as these adjustments sometimes need a small tweak again after a few weeks of use.
