Over time your bifold door tracks and runners can wear or change, or even move. This could cause your bifold doors to become incorrectly aligned or even damaged. This can be a hassle, especially if your bifold door isn't shut properly. This can affect the security of your home. But, if you know where to look and what you should do, then it can be repaired fairly quickly.
First, you must look for any debris that may be present in your tracks and get rid of the matter. Alternately, you can clean the track, and then re-lubricate it and help smooth things out. If the issue persists, you may try tightening or loosening the top screw to align the tracks.
Another common issue with bifold doors is that they begin to slide and scratch the floor. This can be a real pain and can be caused by a number of causes, such as overuse or if they've been improperly fitted. Luckily, there are small adjustments you can make to get your doors back in line.

The bottom pivot can sometimes break. This is a frequent issue for older bifolding doors and can happen in the event that they aren't used regularly or abused. This is usually due to a crack or split on the nylon or plastic cap that holds the metal pivot pin.
This is a simple fix that will require patience and a lot of care. You'll have to replace the plastic or nylon cap, and the pivot pin made of steel. You'll need to replace the bottom brace with a brand new one, and then put it back on the rail.
Doors that are not aligned
A bifold door can be an elegant design for any house, but over time it can develop problems that affect its ability to close and open. Many of these problems are easily fixed and don't require a professional.
The first step is to analyze the problem and determine what is causing your doors to misalign. You will need a level to measure the gap between the track of the door and the track. If you find a gap that is larger at the top of the door than at the bottom, the doors are not aligned. You can fix this by loosening the screw on the pivot bracket and moving it to another notch on the bracket.
If your doors are misaligned, you may need to replace the pivot or anchor pins. They are usually constructed of wood and will wear out over time. To replace the pins you'll need to take off the doors and then remove the pin using flathead screwdrivers or pliers. The damaged pin needs to be removed and a new hole cut for it. If you are required, you will need to cut away the wood where the pin was damaged.
After replacing the pin, attach it to the door and place it on its brackets. If the door does not sit properly you can shim it by adding more wood or plastic. You should be aware, however, that when your door is severely out of alignment it may be simpler to replace it than just to shim it.
If your doors make a scraping noise when they are opened, this could typically be due to debris getting lodged in the running tracks. You will need to remove the obstructions blocking the tracks, and then lubricate them. If the rattling originates inside the door, then the hinges or mechanisms will need to be replaced. You should only trust an established company to install your new doors.
