If you're struggling to open and close your sliding glass door, you may assume that the whole thing needs replacing. However, that is rarely the case. Don't go out and buy a new sliding glass door just yet. In many cases, the door's rollers are likely worn out. These small wheels sit underneath the door to help it glide along the track. When they wear down or break, the door becomes frustrating to use. Replacing the rollers is a manageable DIY project that will likely cost less than $20 for parts from your local hardware store and can give you back smooth and effortless movement for your sliding door in no time.

In addition to replacing the rollers, you can boost the life expectancy of your sliding glass door by performing some upfront maintenance. Start by cleaning the track. Dirt and debris can contribute to your door's roller issues, so if you vacuum and wipe down the track, you'll keep anything from sticking to them. You may also want to use a silicone-based lubricant (not grease) to help move your rollers along without attracting dust.

For this project, you'll need a Phillips-head screwdriver to raise and lower the rollers as well as to remove them. Have a flathead screwdriverand some needle-nose pliers on hand to help pull out the old rollers and a blanket or drop cloth to rest the door on while you make repairs. First, clear the area for the door by removing any blinds or fabric panels covering the door. Note that the fixed section of the door system does not need to be removed. It doesn't have any rollers.

Your sliding glass door has two roller mechanisms, one on each side. When you look at the bottom side edge of the door, you'll see two screws. The screw on the top holds the roller mechanism in place. The bottom one is the adjustment screw to move the wheels up and down. Loosening the bottom screw will retract the rollers into the door frame, making it easy to remove the door. Once you have the rollers on the front and back retracted, lift the door and then angle the bottom outward. That allows you to remove the door. Sliding doors can be heavy, so it might be best to have a second person help.

Once the door is out, place it on its side on a blanket so you can see the rollers on the bottom. Loosen the top screw to detach the rollers. You may need to use some needle-nose pliers to pull them out. You can check the manufacturer's specifications for the proper rollers, but most mechanisms, like this Barton Kramer sliding glass door replacement roller, will fit multiple door types. It is helpful to take your old rollers to a hardware store so you can match them. These Barton Kramer rollers are less than $8, and you'll want to buy two. 

Back home with your new rollers, slide or snap each one into place. Hold the rollers straight while you secure them with the top screw, then push the adjustment screw into position. Make sure the wheels are still retracted. Then, reinstall the door by lifting it into the top track, then lowering it into the bottom track. You can adjust the screws to extend the rollers back down until the door is level and glides smoothly.
