How to Replace Hinges on Bifold French Doors How to Replace Hinges on Bifold French Doors

Bifold French doors take up only a little space, but after lots of use, they may require some maintenance. Most bifold doors use piano-style hinges to open and close. These have long lengths of strong hinge with a lot of fixing holes. Follow these steps to successfully replace the hinges on your bifold French doors.

Step 1 - Removing the Doors

Remove the bifold sliding doors from the tracks by pressing down the retaining pins and pulling the doors off the tracks. At this point, you may also want to remove the door furniture from the doors so that they can lie flat on the floor.

Step 2 - Removing the Old Hinges

Place the doors face down so that the hinges on the back are clearly visible. Unscrew the old hinges and remove them. This should be very easy, though there will be a number of screws which need to be loosened and undone.

Step 3 - Measuring the Hinges

Next you should measure the old hinges to make sure you are replacing it with the right sized hinge. The width isn't very important, but the length needs to be roughly the same. You will find it easier if you cut this to the same length because you don't need to worry about anything catching.

Step 4 - Cutting the Hinges

Once you know how big the hinges need to be, you can then start cutting them. Piano hinges can be cut using a hacksaw or electrical circular saw. Grind down the rough cut edges of the hinges to make sure that they don't catch or cut you.

Step 5 - Fitting the New Hinges

Use the screws to fix the new hinges onto the wall, make sure that these are positioned so that they allow the doors to open freely. Also be careful if you are using hinges which are a different thickness to your original, you don't want to risk poking the end of the screw through the front of the door.

If possible, try to fix into the same holes that were used last time. If this isn't possible, you may need to first drill new holes.

Step 6 - Re-assembly

Once the new screws are attached, you just need to screw the door hardware back onto the doors. After this, you can place the doors back into the tracks by pressing down the small pin and pressing it into the track. Make sure that the bifolding French doors open and close properly without catching or moving slowly. They need to have a smooth gliding movement so that they are very easy to open and close.
