Nowadays, there is the trend of using automatic garage doors which are opened and closed with the help of powerful garage door springs. These highly tensed devices manage the weight of the garage door during the opening and closing process. These components of the garage door come with modern security features that make your garage door safe to use. The smooth opening and closing of the garage door become possible with the help of correctly adjusted garage door springs. These are the parts that make the magic of automated movements of garage doors. They have limited service life this is why they need to be replaced occasionally. Is your garage door spring broken, then it needs to be replaced immediately. The replacement job means another major expense. To be able to save more money, you will have to determine the cost of the replacement project first. Before going through any process, you need to know the uses of garage door springs. There are two types of garage door springs. One is a garage door torsion spring and the other is known as an extension spring. Let me describe them one by one. These springs are commonly used for overhead automatic garage doors. The average life of a torsion spring is approximately 10,000 cycles which could be six to seven years. It also depends on how often you use your garage door, how well it is maintained, and the type of garage door springs used on the garage door. Whenever you open and close the garage door, the hardened steel mechanism of the springs will be stretched and released. When this happens, again and again, the time will come when they get stressed and overused. The spring will become weak and eventually break. It will be the perfect time to replace them with new ones. If only one of the springs breaks, you still have to change both as it is a standard operating rule to keep the garage door safer and functional. It is always that anytime soon the other spring will follow it. It will save you from the hassle of another job. The garage door extension spring is also used to lift and lower the garage door through a stretching system. Their expected life is also 6 to 7 years based on the type and quality of garage door springs. There are a lot of models of garage door springs that you can find online when you need to replace the existing garage door springs. Remember, both types of springs are dangerous and difficult to handle so it is always wise to call professional garage door companies to deal with them.
