Most of the houses in this service area went up between 1938 and 2015, with a median build year of 1983, which means the steel panels on a lot of garage doors here are the same style that was standard in the early 1980s and hasn't been made in years. Across the twenty named communities we cover, housing is mostly 1980s and 90s stock, so a single cracked panel often has no factory match left to order.
Mission Viejo sits in a mild temperate climate band, so panels here fail from sun fade and dings more than from freeze-thaw cracking or hail dents. You don't get the expansion-and-contraction damage that shows up in colder markets - instead you get UV fade on the sun-facing side, a basketball-shaped dent from a backed-into trash can, or a bottom panel that's rusted out from sprinkler overspray hitting it for twenty years straight. None of that is dramatic. It just adds up slowly until one panel looks nothing like the rest of the door.
With 80,921 owner-occupied houses among 172,061 households across the area, a lot of these garage doors are original equipment that the builder installed once and nobody has touched since. That's the root of most panel calls we get: not storm damage, just age and sun doing what they do over three or four decades.
