Misaligned Doors
A bifolding door is a fashionable feature to any home. However it may develop issues that can hinder its ability to open and close. Many of these problems are easy to fix, and don't require a professional.
The first step is to evaluate the issue and figure out what is causing your doors to not align. You'll need a level to determine the gap between the track of the door and the track. If you notice gaps that are larger at the top of the door than at the bottom the doors are not aligned. You can remedy this by loosening the pivot bracket's screw and moving it to another spot on the bracket.
You may have to replace your pivot anchors or pins if you still have doors that are not aligned. They are typically made from wood, and can wear out with time. To replace them, you will have to open the door and then remove the old pin from the wood with pliers or a flathead screwdriver. The damaged pin will need to be removed and a new hole drilled for it. You'll also have to cut the wood where the pin damaged was positioned, if needed.
After replacing the pin, attach it to the door and place it on the brackets. If the door still does not sit properly you can try shimming it by adding more wood or plastic. Be aware, however, that in the event that your door is out of alignment it may be easier to fix it rather than shim it.
If your doors make scraping sounds when they are opened, this could usually be caused by debris getting lodged in the running tracks. You'll need to get rid of the debris that is blocking the tracks, then grease them. If the rattling is coming from the inside of the door, the hinges or mechanisms have to be replaced. It is best to choose a reputable business to install your new doors.
