You may not be a certified garage door technician, but you can certainly take a little time out to visually inspect your garage door. If you have a metal door, you may need to check for rust spots. If you do catch sight of any, it is best to have the spot sanded, primed and painted as soon as possible. Similarly, a wooden garage door can be inspected for water damage. If the door is warped and losing its shape, it means that there is water damage and you should get the door sealed quickly to avoid any further damage. While you are at it, you should also consider washing your garage door regularly. After all, your garage door is one of the first things people see when they pull up to your home, so it better be clean and presentable.
Inspect the Bolts and Screws
A typical garage door opens and closes hundreds of times a year (thousands, if talking about a commercial garage door). All this movement makes it easy for the screws and bolts to become loose. So, you should inspect the brackets on the rollers and the bolts and if they are loose, fasten them using a (socket) wrench.
