Union City's garage stock skews to the two-car, two-door layout typical of homes built in the late 1970s, and with a median household income of $137,194 - below the wider Alameda service area's $163,199 - a lot of those original sectional doors and their factory track have never been swapped out, just patched. That's a long service life for steel track, and it shows: thirty-plus-year-old galvanized rail that's taken one too many bumps from a car mirror or a basketball is the single most common cause of off-track calls we see out this way.
The mild climate here doesn't stress the hardware the way heat-cycling or heavy freeze-thaw would elsewhere, so when a track does fail, it's almost always mechanical wear or impact, not weather. That's a small mercy - it means the fix is usually straightforward once we're looking at it - but it doesn't change the fact that original 1979-era track wasn't built to last indefinitely, and a lot of it in this area is overdue.
