We work on residential garage doors and openers - springs, cables, tracks, rollers, panels, and the opener units themselves. We don't do commercial rolling steel doors or fire-rated doors, and if a job needs structural framing work because the header's rotted or the opening was never square to begin with, that's outside what we take on.
One honest limit: because we're driving in from Salinas, we schedule Gonzales calls rather than treat them as drop-in emergency stops. If a spring snaps on a Saturday night, we'll get you on the list, but we're not claiming a same-hour response out here the way a shop based in town might. Most of the time that's fine - a broken torsion spring means the door won't move at all, which is annoying but not dangerous if you leave it alone and don't force the opener.
