Spring replacement is a big part of the call volume - torsion springs on doors installed from the 90s onward, extension springs on the older stock still standing from the 1976-1986 run. We replace rollers, cables, and bottom brackets, realign bent tracks, and swap out openers when the motor or gearset has had it rather than when the remote just needs a battery.
Madison sits in a cold-moderate climate band, which doesn't mean brutal winters, but it does mean a door with a bad bottom seal or a misaligned panel lets real cold into an attached garage for a good stretch of the year. That's a common complaint we hear from owners of the 1980s and 90s builds that make up most of this area's housing.
Across the service area there are more than 12,600 owner-occupied houses, and a good share of them are sitting right at the age where openers start failing - the logic boards and drive gears in units installed a decade or two back wear out before the door itself does. We replace full door systems too, when a repair isn't worth chasing anymore. We don't do new garage construction - that's a different trade - but anything on an existing opening, we handle.
