Of course, it is vital to check your garage door monthly. First you have to check the springs, because the springs carry heavy loads and they need to be strong, otherwise the heavy door can’t be lifted. You will have to look at whether the springs are rusted, are they broken, or are they fine? Then you look at the door itself, and whether or not there are rusted edges or sharp edges, which can possibly hurt someone. Lastly, you must look at the pulley system to ensure it is in good shape. Applying chain lubricant is always a good idea too.
