Most screen doors don’t slide properly after a few seasons because the are not maintained right. The screen door has rollers and need to be cleaned and oiled with wd40. You can do s screen cleaning by hosing off the screen door right on the spot, letting it dry and then spray the track and rollers with some lubricant. Adjusment on each roller is also necisary and can easily be done with a philips screw driver, turn one way and the frame drops turn the other and it lifts.
One of the most important things to check when doing screen door repair is, look at the track, is it clean, is there rocks and dirt in it, is it warped, rusted or oxidized, all these things will affect the way the patio door slides and need to be fixed in order to prevent you door from sticking.
