Across the 136,012 owner-occupied houses in this service area, the calls cluster around a few things. Torsion springs that snapped on a door built before the 2000s and never got serviced. Rollers and hinges worn through on doors from the 1980s and 90s stock that make up most of what's out there. Openers that lost their force balance after years of a heavier door dragging on a stretched cable. Bent track from a bumper tap in a tight driveway, which shows up a lot in the older, narrower-garage layouts from that same build era.
We'll also tell you when replacement beats repair - a door from the early part of that 1958-2003 range, with a warped panel and a dead spring and a worn track all at once, usually costs more to patch piece by piece than to replace outright. We'd rather say that up front than sell you three repairs that don't add up to a door that lasts.
