How to make a garage door less noisy?

To make a garage door less noisy, you need to address the root causes of vibration, friction, and loose hardware through a full maintenance routine. Start by disconnecting the opener with the emergency release cord so you can move the door by hand and isolate opener noise from door noise. First, tighten all bolts and screws on the tracks, roller brackets, and hinges, because loose hardware rattles loudly when the door moves. Use a socket wrench but do not overtighten. Second, clean the tracks with a damp rag to remove dirt and hardened grease that causes grinding, and then wipe them almost dry. Third, lubricate all moving metal parts with a proper garage door lubricant, not standard WD-40. Spray the roller bearings and stems, the hinge pivot points, the torsion spring coils, and the bearing plates at the ends of the spring tube. Fourth, replace worn parts. Old metal rollers with unsealed bearings are often the loudest component, and upgrading to quiet nylon rollers with sealed ball bearings can reduce noise by 50 percent or more. Fifth, check the opener. A chain drive is louder than a belt drive, so lubricate the chain and consider adding rubber isolation pads between the opener motor and ceiling mount. Finally, ensure the door is balanced and the springs are properly adjusted, as an unbalanced door strains the opener and makes extra noise.
