Lubrication Is Only One Part Of Maintenance
Garage doors combine rollers, hinges, bearings, springs, cables and an opener. Some moving metal joints benefit from a light application of a suitable garage-door lubricant, but lubrication cannot correct a loose cable, damaged roller, bent track or unbalanced door.
For Burnaby homes, moisture and seasonal temperature changes make periodic inspection worthwhile. Start with the door closed, disconnect electrical power if you are working near opener components and never loosen spring, cable or bottom-bracket hardware.
