Regular maintenance is the key to keeping it in top condition when it comes to your garage door. You should think about repairing or replacing parts if you notice any signs of damage, such as sticking, scraping, or grinding noises when opening and closing the door. If your door appears crooked, then this likely means that one side has come off its track and needs repair. Additionally, you may want to consider a new opener if yours isn't working properly anymore; this will help prevent further issues from occurring over time. Lastly, check for rust on both the exterior and interior of your garage doors every few months; if any areas have corroded too much, they need to be repaired right away before further damage occurs.
