1. If your sliding door is getting stuck, you might be able to save loads of money by repairing them.

2. Firstly look at the track to see what is causing the issue, in most case its either the worn rollers or track.

3. If you find the rollers are the issue, proceed to remove the door from the track. (An experienced person should do this job)

4. Carefully tilt the door onto its side where you can see the rollers

5. Now you should be able to see them.

6. Check both rollers to see how they're attached to the door. Usually, you'll find two hidden screws.   

7. Now carefully remove the rollers by undoing both screws.

8. Once you've got the correct replacement rollers, go ahead and install them. Next is to re-hang the door in its position, fit the top guide first.

9. Make sure the door is aligned back in the correct position if it's not square you'll need to adjust the rollers to make them fit neatly.
