Our service area sits in a moderate-heat climate band, and that heat cycling is part of what ages the hardware on a door built in the late '90s or early 2000s - lubricant breaks down faster, rubber seals dry out, and steel track expands and contracts enough over 20-plus years to loosen fasteners. Perris's median income runs around $82,523, close to the wider area's $83,246, so we're not seeing a pattern of deferred maintenance tied to cost here - it's more that newer doors just don't get flagged as due for service the way an obviously old door does. The door looks fine from the driveway. The spring and rollers don't know how old the house is; they know how many cycles they've run and how much heat they've sat in.
