Union City's housing stock skews newer than most of the area we cover. The median build year here is 2002, well past the 1978 median for the service area as a whole, where most homes date to the 1960s and 70s. That gap matters more than it sounds like it should.
Homes built around 2002 mostly came with factory-installed steel sectional doors on torsion springs mounted on a center shaft above the opening - not the older side-mounted extension spring setups you'll find in the area's 1960s and 70s housing. The openers are more likely to be chain or belt-drive units from the early 2000s, with circuit boards instead of the simple relay switches in older garages.
With 11,533 households in Union City and a median income of $47,635, we see a mix of original builder-grade doors that are now over 20 years old and starting to show wear in the rollers and bottom seal, alongside some updated models where an owner already swapped the opener or panel once. Either way, the failure points are different from what we run into on older stock elsewhere in the area - it's rarely a seized torsion spring from decades of rust, more often a worn roller, a failing circuit board, or sensor wiring that's degraded.
