You should schedule a maintenance inspection from a commercial garage door company. A technician will perform a full inspection of the garage door and conduct routine maintenance. This maintenance will include tightening bolts and screws, lubricating key parts of the door, adjusting the garage door spring tension, and performing an overall inspection of the garage door. Upon approval, they will fix or replace any parts on the commercial garage door that need this service. Once they complete the job, your commercial garage door will be operating again at top-performance.
