Sliding Screen Door Stuck At Top
Determine exactly where the door is sticking before deciding on a remedy.
Sliding screen door stuck at top. The metal frame around the screen door is easy to bend and warp. If the edge of the door is hitting the frame try tightening the screws on the top middle or bottom hinge on both the door frame and the door being careful not to over tighten and strip the screws. If it fits too loosely in the tracks any vertical movement of the door will cause it to come unseated and it will fall. Find the rollers at the bottom of the door.
If your sliding door is sticking or dragging along the tracks making a grinding noise the springs in the rollers could have become loose causing it to sag. If the track is bent or squashed straighten it with smooth pliers and file. Almost all sliding patio doors are adjustable when it comes to height. To fix this you can adjust the height of the rollers by the screws on the rollers.
These hole are often covered with a plastic plug. Locate the spring assembly which is often on the top. Again this is a fairly simple problem to fix. First look at the lower track.
Your door is old and worn out. Most sliding patio doors have one or two small holes at the top and bottom of the door for adjusting the roller height. In some instances the sliding screen door will fall out repeatedly because it is too small. Most sliding patio screen doors can be unstuck with a little maintenance.
