DIY-safe lubrication
A homeowner can handle wiping down tracks and putting garage-door-specific lubricant on rollers and hinges every few months. What you shouldn't touch is the torsion spring itself - winding or unwinding it under tension is how people lose fingers, not an exaggeration. Housing in this service area was built mostly between 1959 and 2014, with the bulk of it going up in the 1980s and 90s, so a lot of these doors are running original torsion springs and openers that are decades past their rated cycle count.
