Brentwood's median home was built around 2003, which puts most of this town's garage doors a full generation newer than what we see in older parts of the service area. That matters more than people think. A door built in 2003 almost certainly came with a factory-wound torsion spring system, a steel sectional door instead of a one-piece wood slab, and a photo-eye safety sensor pair wired into the opener from day one, because that was already required hardware by then. The failures we get called out for here are different from the failures in 1970s neighborhoods. You're less likely to have a dead sensor from age and more likely to have a spring that's simply worn out its cycle count, a plastic idler pulley that's cracked after two decades of summer heat, or an opener logic board from the early 2000s that's finally quitting. The climate here runs on the moderate side for heat, so you're not fighting the kind of extreme thermal swings that crack springs early, but twenty years of normal use still wears out the same parts in every house built in that window at roughly the same time.
