How Do I Fix a Sagging or Misaligned Wardrobe Door?

Most sagging or misaligned wardrobe doors are a straightforward fix that a confident DIYer can tackle in under an hour. The solution depends on whether you have hinged swing doors or sliding/bi-fold doors, but in most cases it comes down to adjusting the hardware rather than replacing anything. Here's how to diagnose the problem and sort it out.

Diagnosing the Problem First

Before reaching for a screwdriver, take a good look at what's actually happening:

• Door drops at the latch side — usually a hinge issue (loose screws or worn hinge)
• Door rubs on the frame or floor — could be hinge sag, a swollen frame, or a warped door
• Sliding door jumps off the track — worn rollers, bent track, or misaligned guides
• Bi-fold door won't close flat — pivot pin or top guide out of alignment
• Gap is uneven around the door — hinges need adjusting or the frame has moved

A quick check: close the door slowly and watch where it first makes contact. That tells you which end needs adjustment.

Fixing Hinged Wardrobe Doors

Tighten or Replace Loose Hinge Screws

This is the most common cause of a sagging door. Open the door and check every screw on every hinge — both the door leaf and the frame leaf. If screws spin without gripping, the timber holes have stripped.

To fix stripped screw holes:

1. Remove the screw and pack the hole with wooden toothpicks or a matchstick dipped in PVA glue.
2. Let it dry for at least an hour.
3. Re-drive the original screw — it will grip into the timber filler.

For a more permanent fix, use a slightly longer screw (e.g. step up from 30 mm to 45 mm) to reach fresh timber behind the jamb lining.

Adjusting Concealed (Euro-Style) Hinges

Many modern wardrobe doors use concealed cup hinges, which have built-in adjustment screws — a real bonus. There are typically three adjustments:

Use a Phillips screwdriver and make small turns (quarter-turn at a time), then close the door to check. Most doors need only 1–2 mm of correction.

Fixing a Warped or Swollen Door

NZ's humidity — especially in older homes or rooms without good ventilation — can cause timber doors to swell. If the door is only slightly warped, adjusting the hinges to compensate can help. For significant warping, the door may need to be planed or replaced. Check your home's ventilation while you're at it; Energywise has good guidance on managing indoor moisture.

Fixing Sliding Wardrobe Doors

Adjusting the Rollers

Sliding doors hang from top rollers that run in a track. Most rollers have a small adjustment screw or nut underneath the door that raises or lowers the roller, lifting or dropping the door.

1. Open the door to access the roller at the bottom edge (or top, depending on the system).
2. Use a Phillips or flat-blade screwdriver to turn the adjustment screw.
3. Raise the door until it clears the bottom guide and runs smoothly.

If the rollers are cracked, flat-spotted, or won't adjust, replacement rollers are available from Bunnings or Mitre 10. Take the old roller in to match the size and style.

Cleaning and Straightening the Track

Dirt, hair, and debris in the bottom track is a very common cause of sliding doors jumping or sticking. Vacuum the track out, then wipe it with a damp cloth. A light application of silicone spray lubricant (not WD-40, which attracts dust) keeps things running smoothly.

If the track is bent, you can often gently straighten it with pliers. A badly damaged track will need replacing — these are usually aluminium extrusions available from hardware stores or specialist door suppliers.

Realigning Bi-Fold Doors

Bi-fold doors have a pivot pin at the bottom and a top guide that slides in a track. If the door swings out at the bottom or won't fold flat:

1. Check the bottom pivot — it usually has a height-adjustment nut. Raise or lower it until the door sits plumb.
2. Check the top guide bracket — loosen the screws, shift it slightly, and retighten.
3. Make sure the track is level. Use a spirit level; if the track has dropped, the fixing screws into the ceiling may need to be repositioned.

Tools You'll Need

• Phillips and flat-blade screwdrivers
• Spirit level
• Tape measure
• Toothpicks or matchsticks + PVA glue (for stripped holes)
• Silicone spray lubricant
• Replacement screws (longer gauge) if needed

When to Call a Professional

Some wardrobe door problems point to bigger issues that go beyond a simple adjustment:

• The door frame or surrounding wall has moved — this could indicate foundation movement or structural settling, which should be assessed by a Licensed Building Practitioner (LBP).
• The floor has dropped or the ceiling has lifted — again, get a structural assessment before assuming it's just the door.
• The door is part of a fire-rated or acoustic-rated assembly — repairs must maintain the rating; consult a professional.
• You're not confident working at height (e.g. tall robe doors on a ladder) — safety first.

For anything beyond basic hardware adjustment, it's worth getting a qualified carpenter to take a look. You can find experienced local carpenters on tradedirectory.co.nz.
