Replacing a sliding door track is a fairly simple job that you may eventually have to do. Over time, the door tracks become worn out and bent. The rollers may also be broken. After a few years, sliding doors may not close properly and sometimes they can become difficult to operate because they repeatedly get stuck. In some cases, the rollers and tracks can simply be cleaned, but eventually, they will need replacing. Replacing bent or damaged tracks is not a particularly difficult or time-consuming job.
Remove the Doors
Depending on the size of the door, you may need somebody to help you with this step. To remove the door, grip both of the sides and lift it so that the roller is clear of the track. Pulling the bottom of the door towards you, gently remove the door from the frame. Do the same with the other door.
Inspect the Tracks
Remove any dirt from the track and examine the track carefully. Do not replace it if you don’t need to. If there are any wear and tear on it and especially if the track is bent, it will need replacing.
Remove the Old Door Track
Remove the old door track by taking out the screws that hold it in place. Have somebody to help you by holding down one end of the track so it doesn’t buckle when you move it. Measure the length of the old track so you know how long the new one needs to be. Remove the track from the top of the door in the same manner. Take the old track to your home improvement store and use it as a guide for getting the new one.
Cut the New Track to Size
Hold the old track to the new one to compare the size. Make sure that the holes line up. Use a marker pen to place a mark on the track where you will need to cut it. Cut the track to the right length using the hacksaw. Do the same for the track which is to be installed at the top of the frame.
Attach the New Tracks in Place
Screw the new tracks in place with the replacement screws. Clean the door rollers using a brush and denatured alcohol. It is also a good idea to apply some lubricant onto the rollers. Make sure you remove any excess using a rag. Ensure that the tracks are properly attached and then you will be ready to lift the doors back in place.
Return the Doors
Place each door by lifting them into the upper track at an angle. Bounce the rollers back into the lower track and then test the doors to see if they slide as they should. You will likely need somebody to help you with this.
