Safe maintenance tasks
That's real maintenance and it costs you nothing. What you shouldn't touch is the torsion spring above the door or the cables running down each side. Those springs hold enough tension to break a bone or worse if the winding cone slips, and on the older torsion setups still common on houses built through the 1960s and 70s across Fremont's neighborhoods, the hardware is often original and more likely to let go under load than newer parts would.
