Because so much of Hollister went up around 1989, we see a fairly consistent pattern: steel sectional doors, torsion springs mounted on a center shaft above the opening, and openers old enough now that the logic boards and drive gears are the first things to go, not the door itself. Torsion spring failure on these doors is loud and sudden - usually a bang from the garage, then a door that won't lift or lifts crooked. The springs on a late-80s double door are sized for a heavier panel than the old one-piece slabs in older neighborhoods nearby, so a wrong-size replacement spring will wear out fast or strain the opener.
With median household income in Hollister at $101,979, most of what we're asked to do here is straightforward replacement of worn parts - springs, rollers, the opener itself - rather than full custom retrofits. The building stock is uniform enough that we're not guessing at nonstandard track widths or odd ceiling clearances as often as we do in older sections of the broader area.
