When a sliding screen door starts giving you problems sliding, it might be time for repair. We come out check it to see is the frame is in good condition, then we check the roller set to see if it still turns good. All four rollers should spin good and adjust up and down. If you use a screw driver you should be able to raise and lower each wheel.
If the doors frame is good and straight we should be able to rescreen it,our different meshes are, regular fiberglass for simple insect protection,then we carry the pet screen which is for dogs cats and kids. This pet proof mesh is 7 times stronger then the regular screen mesh and also last just as long.
