Sometimes it s an issue with the closing mechanism.
Reattach the head stop first otherwise it could fall out.
Close the door to check the fit.
Open and close the door to make sure that the turnbuckle isn t blocking the door seal then mark its screw holes with a pencil.
Determine which hinge must be shimmed to adjust door and create even spacing.
Continue tightening and checking until the door no longer sticks.
Flatly position the turnbuckle by the bottom corner of the door.
Close door and check the spacing at the top and latch side of the door.
Other times the hinges or latch on the storm door aren t screwed in tightly.
Hold door hinge against cardboard and use utility knife to cut around hinge.
Roll the door toward the latch side jamb then turn the adjustment screws until the door is parallel with the jamb.
