Additionally, check for structural or cosmetic damage to the door’s surface. Further, it is critical to inspect the garage door seals at the door’s edges and beneath the bottom of the door.

When the door is closed from the inside, inspections should be performed to check the tension spring, guide rails, and door mounting hardware. Loose components indicate that the garage door needs repair or replacement of parts.

Additionally, it is critical to inspect the door opener and ensure that the drive system, whether chain, belt drive, or screw drive does not have excessive slack.
