Sliding glass patio doors operate on a set of small rollers that allow them to travel back and forth on the track. Over time, normal wear and tear can require that you replace these rollers to get the door moving smoothly again. Rather than pay up to £65 to have a professional installer replace your sliding patio door rollers, do it yourself with some basic tools. With a modest investment of time, you can save yourself some money and bask in the satisfaction of a job well done, all while improving the function, security and value of your own home.

Remove the sliding glass door from the frame. It is best to have someone help you with this task because the door may be quite heavy. Lift the door up off of the track and pull it out, bottom first. If you have lifted the door all the way up and the door still won't come out, adjust the rollers lower with a screwdriver to create more room.
Remove the screw that holds the rollers in place. There are usually two rollers, located on each end of the door. In many cases, the screws that hold the rollers in place are the same screws that hold the bottom piece of the door frame on. If the rollers are indeed screwed on through the bottom piece, remove that as well. If it won't just pull off, tap on it with a rubber mallet to remove the piece.
Take the old rollers with you to purchase matching new rollers.
Screw the new rollers onto the door frame, remembering to go through the bottom piece of the door if you had to remove it. Adjust the rollers all the way down initially to make it easier to get the patio door back into the frame.
Replace the door back into the frame, top first. Again, ask someone to help you with this task. If you adjusted the rollers all the way down it should go in fairly easily.
Adjust the new rollers. Use a screwdriver to turn the screw that adjusts roller height. Raise the rollers a small amount and test the door. If it feels loose, adjust them a bit more and check again. The door should have a snug fit, yet slide smoothly back and forth without a lot of effort.
Tips and warnings
- Replace both rollers at once, even if one of them is in better condition. Using one old roller with one new one makes the new roller wear out faster because it must compensate for the lower performance of the old roller.
- Adjusting the rollers for a snug fit improves home security by preventing would-be burglars from lifting the door off of its frame to gain entry to your home.
