What maintenance can homeowners safely do themselves versus leaving to pros?

The one maintenance task most homeowners can handle safely is lubricating the hinges. Over time, hinges can dry out and become noisy, but a quick application of the right lubricant can restore smooth, quiet operation.

Beyond that, other components should be left to a professional to avoid potential safety risks. Homeowners can also listen for unusual noises and watch for changes in how the door moves, but any repairs involving springs, cables, tracks, rollers, or the opener system should be handled by a trained technician.
