Costa Mesa's housing stock spans 1938 to 2005 with a median build year of 1970, but Cerritos sits a few years past that midpoint, closer to 1974. That gap matters more than it sounds. A house built in 1974 is more likely to have come with a standardized torsion spring setup than the mixed bag of extension and torsion hardware you find in the older pockets closer to Costa Mesa. It doesn't mean the springs last longer - a spring is rated for a cycle count, not a birth year - it means when one fails on a Cerritos door, the replacement is usually a known part rather than a hunt through three different spring gauges to find what a 1940s conversion left behind. The mild coastal-influenced climate across this part of Orange County also means we're not chasing the kind of temperature-swing fatigue that cracks springs in harsher climates. Around here, springs give out from cycle count and lubrication neglect, not from winter cold snaps.
We drive the 17 miles out from Costa Mesa for these calls, and the housing-era difference is the first thing we check before we open the truck doors.
