How to Fix the Sliding Door for a Closet

For narrow closets or toilet stalls in a corridor, sliding or bifold doors is a fantastic space-saving option. Nevertheless, these doors have a tendency to become bumped and need to be readjusted when that happens. With the steps below, you’ll see how easy it is to fix a bifold door. It’s much simpler than you think. 

Closet doors typically glide down a track that is mounted above the closet opening. Folding doors, or bifolds, are secured at the bottom and top of a single side. A top channel on the other side allows a guide pin to move smoothly. Replacement sections for these entrances may be purchased from any home improvement shop, hardware store, or even online. 

Cleaning the bottom track of a sliding closet door with a moist cloth can keep the door moving smoothly. Keep the track dry; rollers need lubrication, but they will attract dust if you put them on the track. To take out a door, you have to raise up on its bottom and then tilt it out. Unscrew the roller and pull it out if it becomes stuck. If cleaning doesn’t help, you’ll need to get a new roller unit.

Why Do Closet Sliding Doors Get Stuck? 

Identifying the root cause of the issue is the first step in repairing your sliding closet doors. The most common cause of sliding door difficulties is dirt buildup, followed by wheels coming loose from the tracks. Damage and loose screws can make it difficult to open and shut your closet. If your sliding doors are difficult or impossible to open, try these solutions. 


Unconventional Guide Track – The roller wheels often come loose from their guide track, which is one of the most typical problems. As the wheels fall off, the door might become difficult to open and close. 


Build up of Grime and Rust – The track of your sliding closet doors may accumulate grime and rust if you don’t clean it regularly. The debris, when combined with the lubricating oil in the track, forms a paste that makes the door difficult to open and close. 


The Screws Are All Loose – The door may squeak or scrape against the floor, ceiling, or walls if the screws holding it in place are loose. 


Deteriorated Tires or Barrings – Barrings and wheels wear out with time, which is not very common but may happen. If opening your door is a sluggish, grinding, or skipping process, this is likely the cause. 


Broken Doors or Tracks – If the door’s track is bent or warped, the door won’t slide smoothly. A stuck or locked door might be a sign of damage.


Here are some steps on how to fix a sliding door in general: 

Take a deep breath and stand back to analyze the issue before you start taking your closet door apart and taking it off the track. Does the closet door seem to be slanted to one side? The door may need its screws tightened before it can close properly again. After that, proceed as follows:

  • Inspect the Screws 

Make sure that no screws on your sliding door’s hardware are missing or loose. To adjust as necessary, tighten. You should replace any screws that are particularly worn or old. 


  • Activate the Rollers 

Do you have fresh flooring? The friction created by walking on the new floor may have jarred your closet door loose. 

You may prevent the door from scratching the floor by adjusting the roller height using the screws on the rear of the door. To fix a pocket door that has sagged on one side, use a wrench to secure any loose bolts. 


  • Take the Guide out of its screw 

There is a wide range of closet door types, each with its own unique hardware configuration. Bypass doors glide over rollers mounted in the upper door jamb of the frame and are held in position by a hinged guide set into the floor. 

The “fold” that the door uses to disappear into the wall is guided by guides in most cases when using a pocket door. Standard bifold door construction calls for guides that swivel on pins to provide the accordion-fold effect. 

The pins are inserted into the top and bottom of one door panel, while the guide is situated at the opposite top corner of the second door panel. The panel cannot be opened or closed because of this guide, which slides along a track. 

Locate the guide in your closet door, unscrew it, and then remove the guide entirely to take the door down for examination and repair. 


  • Get Rid of That Door! 

After the door’s hardware has been removed, you may take the doors down. To protect the floor while you work on the door, spread a thick blanket or mat there. Raise the door 30 degrees, so that the bottom is closest to you and the wheels are lifted clear of the track. Carefully set it down on the floor or blanket while you troubleshoot the issue. 


  • Find Any Potentially Hazardous Waste 

It’s possible that a little cleaning is all that’s needed to get the door back on its track. Dirt and debris may accumulate in the closet track and eventually push the door out of alignment. 

To remove the stubborn dirt, use a toothbrush or a tiny brush and scrape the area with soap and water before vacuuming. After you’re done, lubricate the track with WD-40 or silicone spray. For best results, it’s recommended to do this maintenance on a seasonal basis. 


  • Check the Rails 

Now that the door is no longer attached to its track, you may inspect it thoroughly to find any problems. Check the track for any sharp turns that might be causing the door to move erratically or even to leap the rails. 

Bends in the track may be straightened by inserting a piece of wood into the track and standing on it while tapping the track with a hammer. To replace the track totally if this doesn’t work due to a sharp turn, have a professional closet installer have a look. 


  • Dust Off That Door 

Using a hammer, knock out any tack nails that may be embedded in the door’s threshold. Sanding the door’s base with sandpaper should release the tension between the door and the track, allowing the door to slide freely down the track once more. The door may be made level by fastening a plank of wood to its base. 


  • Repair or Replace Worn-Out Roller Wheels 

If your roller wheels have flat patches, the doors will become stuck in the track. Any broken or worn-out roller wheels should be replaced immediately. 


  • Secure the Door Again 

As a final step, replace the door in the exact same way that it was removed. At a 30-degree angle, bottom nearest to you, insert the top roller into the top track of the bypass door. You may connect the door into the track by straightening it and then pulling it down slightly. 

To re-establish the door’s stability, all of the components must be replaced in their respective guides. To install a bifold door, insert the pivot pin into the top-right bracket, raise the door slightly, and then drop the bottom pin into the bottom bracket.

What Should I Do If My Bifold Door Is Stuck Open? 


  1. Take off the faulty folding door. Depending on the size of the bifold door, you may be able to just raise it up and it will slide off the track. A spring pin may need to be depressed vertically or horizontally to be removed. 
  2. Discover the bracket that runs along the top of the framework. Loosen the bracket with a screwdriver and slide it so that it is just within the door frame. Tighten the screw one more. 
  3. Mount the door back where it belongs and ensure a secure latch. If the door is still awry, try pushing the bracket farther away from the inside of the door frame.


Final Words

It’s a pain to realign the tracks on your closet door. A door or track may require some care or modification if it continues falling off its tracks, but the problem may sometimes be fixed quickly. The door has to be taken off its hinges so that it may be readjusted and cleaned before being reattached. 

If you believe this will be too challenging, you may always get help from a professional or a friend, or a relative. You might save time by doing things this way.
