Garage door maintenance consists of the following:

Clean the tracks, rollers and hinges. Since oiled tracks collect dirt, clean the tracks, rollers, and hinges with a rag dampened in paint thinner.

With the door in the down position, apply penetrating oil to the tracks, rollers and hinges. Wipe away any excess oil with a paper towel or rag.

Inspect bolts and screw to ensure all are properly tightened and secured.

Check the mechanical components (chains, pulleys, rollers, hinges, etc.) for signs of excessive wear.

Check for loose putty around windows.

Inspect weather-stripping at the bottom of the door to ensure it makes a tight seal when the door is closed.

Note: Garage door springs are under great tension. Use extreme caution.
