Most of what we see in Gardner traces back to builder-grade equipment reaching the end of its first life cycle. Openers installed when these houses were new are now old enough that the logic board or the drive gear is the thing that goes, not the motor itself - a chain drive from that era running loud and slow is usually the gear, not a reason to replace the whole unit. Torsion springs on a factory-spec door at this age are also right in the window where they're due, whether or not they've broken yet; we'd rather replace a spring that's close to its cycle count on a scheduled visit than get the call after it snaps on a cold morning. Rollers are the other common one - stock nylon rollers from a 2000s build start chipping and binding right around now, and swapping them out before they seize the track is a cheap fix compared to what a bent track costs. With about 8,175 households in Gardner, the pattern repeats often enough that we can usually tell what we're walking into before we open the truck.
