If you have a damaged sliding door track, it can make opening and closing a patio door difficult. Replacing the sliding door track may also be necessary when replacing a patio door or upgrading from aluminium rails to stainless steel for easier sliding. These types of tracks are available in many widths and are used for sliding doors rather than French doors, which are hinged. You can replace a section of the track or the entire thing, depending on the reason for replacement. The track can be replaced with a sliding door replacement rail or sill track cover.
Measure the width of the existing track before purchasing a new one to ensure that you purchase the right replacement for the sliding door.
Remove screws from the door track area to be replaced. If you are replacing the door, the entire track needs to be removed. If the track is damaged, only remove the screws in the area to be replaced.
Measure the door frame or the damaged area to get the length of track that will be needed for this project.
Use the saw to cut the track for removal.
Pry up the piece of track to be replaced using the prybar or a flat head screwdriver.
Cut the new track to the measurement in Step 2. The new track piece should fit snugly.
Replace the damaged track and fasten with screws. If replacing only a portion of the track, be sure that the door slides smoothly along the new piece without catching. If the problem has not been eliminated, consider replacing the entire track.
