Read the instruction manual that came with your storm door at least once before beginning the mounting process so that you understand the basic procedure. Measure the inside dimensions of the door jamb, horizontally and vertically, on the outside face. Check the acceptable range of dimensions in the instructions. If the frame is improperly sized, cut 1-by-2 lumber strips to fit and nail and screw them to the face of the jamb to adapt it.
Most storm doors come only partially assembled. Attach the hinges, bore for hardware and any other tasks that the directions call for. Fit the hinge side piece of the metal frame to the door and attach the hinges. Double-check the action of the handle and switches to ensure proper action before installation. On some models, screens and glass may be installed or adjusted at this point, as well.
Attach the handle side piece of the frame to the jamb with the screws provided with the door. Use a wood chisel mortise out behind the deadbolt opening as required. Fit the top along the top of the jamb. Add a piece of 1-by-2 to shim it out, if needed, to make it even with the other frame pieces. Stand the door upright and fit the hinge side of the frame in place. Attach the hinge side of the frame to the hinge side face of the jamb, or the 1-by-2 shims you added.
Mount the closer hardware to the wall first, following the directions with the door for placement and height. Fit the door end plate on the closer to the face of the door and mark it for screw holes. Drill the screw holes and attach the closer firmly. Adjust the height of the sweep along the bottom of the door, if needed. This places the rubber against the floor for a good seal.
