At least once a year you should examine the garage door(s) on your property. To insure for proper operation and the longevity of your 
investment, we recommend that you pay-attention to your garage during daily use. When you find time to do a relatively simple walkthrough, follow these steps:
1. Disengage your opener by means of the emergency release and manually open and close the door. During this time, the garage should operate smoothly without making loud noises. If you can open your garage door with one hand, make sure that it’s not flying up or slamming shut.
2. Check the cables and chain, torsion springs, rollers, and track. As you look at those, also go over the hinges and mounting brackets because sometimes screws come loose.
3. Perform preventative maintenance by having a good lubricant that is made for garage doors. Remember that WD-40 is not a lubricant. With your garage door closed, place a tiny amount at each point on the door where there’s a moving part. When you’re finished, manually open and close the door to work the lubricant in. Don’t forget the bearings on a torsion spring (which is located above the door when closed).
Garage door systems will last about 10-20 years. Like anything else that you use, if there’s high usage and poor maintenance, you can’t expect that your investment will last long. Appropriate care will help to increase the lifespan of your garage door and opener system. If something is wrong when you are performing a walkthrough it is important to repair it promptly. Garage door maintenance is a good way to prevent costlier future repairs. If you have a demanding schedule or cannot perform the maintenance yourself, hire professionals to do it.
