Most “my storm door won’t latch” calls here come down to two things: the opening is slightly out of square (common with small seasonal movement over loamy alluvial soils with caliche layers) and the door hardware gets cooked by heat and sun. Add Vegas wind and you get hinge stress, closer seals drying out, and screws loosening in soft trim. During monsoon bursts, wind-driven rain finds any tiny gap, so weatherstripping and sweep alignment actually matters even in a dry climate. The clean install is: verify reveal, shim hinge side, hit solid framing with long fasteners, set closer speed + backcheck, and tune the latch/strike so it closes smooth instead of slamming. Homeowner telltales are pretty consistent—door “bounces” off the latch, rub marks at the top corner, or it yanks open when the wind kicks up.
