West Lake Hills carries a median household income near $211,471, well above the roughly $121,750 median across the wider Austin service area, and that shows up in what's already been upgraded versus what's original. More owners here have replaced a noisy chain-drive opener with a belt or screw-drive unit than the typical household elsewhere in the service area - but the door itself, the springs, the track, often haven't been touched since the house was built around 1988. That's a full decade behind the service area's overall median build year of 1998, which runs newer stock with lighter panels and different spring tension. The mismatch is what causes the odd calls: a brand-new opener straining against original springs it was never sized for, or a quiet belt drive masking a track that's been out of alignment for years. Fixing the opener without checking the door underneath just moves the failure point.
