Bifold doors are a popular choice for many homeowners due to their space-saving design and aesthetic appeal. However, one common issue that can arise with bifold doors is when they don’t close flush, leaving gaps and compromising privacy. In this article, we will explore the possible causes of this problem and provide practical solutions to help you address it effectively.

1. Incorrect Installation

One of the main reasons why bifold doors may not close flush is incorrect installation. If the doors were not installed properly, they may not be aligned correctly, resulting in gaps when closed. To rectify this, it’s advisable to consult a professional installer to ensure the doors are correctly aligned and adjusted.

2. Warping or Bowing

Over time, bifold doors may warp or bow due to changes in temperature and humidity. This can lead to misalignment and prevent the doors from closing flush. To address this issue, you can attempt to straighten the doors by applying gentle pressure or using weights to encourage them to realign. If the warping or bowing is severe, it may be necessary to replace the affected door panels.

3. Damaged or Worn Hinges

Faulty hinges can also contribute to bifold doors not closing flush. Inspect the hinges for any signs of damage or wear, such as loose screws or bent components. If any issues are detected, replace the hinges with new ones of the same size and type to ensure proper functionality.

4. Insufficient Clearance

Insufficient clearance around the bifold doors can hinder their smooth operation and prevent them from closing flush. Check if there are any obstructions, such as furniture or objects in the way, that may be interfering with the doors’ movement. Clear the surrounding area to provide sufficient space for the doors to operate freely.

5. Loose or Misaligned Tracks

The tracks on which bifold doors slide can become loose or misaligned over time, causing the doors to not close flush. Check the tracks for any loose screws or debris that may be obstructing the doors’ movement. Tighten any loose screws and remove any obstructions to ensure smooth sliding.

6. Inadequate Lubrication

If bifold doors are not properly lubricated, they may become stiff and difficult to close flush. Apply a suitable lubricant, such as silicone spray or powdered graphite, to the tracks, hinges, and pivot points. Regularly lubricating these components will help maintain smooth operation and prevent issues with closing.

7. Incorrect Door Size

In some cases, bifold doors may not close flush if they are not the correct size for the opening. Measure the dimensions of the opening and compare them to the doors to ensure they match. If the doors are too large or small, consider replacing them with ones that are the appropriate size to ensure a proper fit.

8. Excessive Weight

If bifold doors are carrying excessive weight, it can strain the hinges and prevent proper closure. Remove any heavy objects or decorations that may be adding unnecessary weight to the doors. If necessary, redistribute the weight evenly across the doors or consider using lighter materials.

9. Structural Settling

Over time, buildings can undergo structural settling, which may affect the alignment of bifold doors. If you suspect this to be the cause, it’s advisable to consult a professional contractor or engineer to assess the situation and recommend appropriate solutions, such as shimming or realigning the door frame.

10. Seek Professional Assistance

If you have exhausted all troubleshooting options and your bifold doors still fail to close flush, it may be best to seek the assistance of a professional door installer or repair specialist. They have the expertise and tools to diagnose the issue accurately and provide tailored solutions to ensure your bifold doors operate smoothly and close flush.


By addressing the possible causes mentioned above, you can troubleshoot and resolve the issue of bifold doors not closing flush. Remember to consult professionals when necessary and prioritize regular maintenance to keep your bifold doors functioning optimally. Enjoy the convenience and elegance that properly closing bifold doors can bring to your home!
