The average spring on a garage door, if installed correctly, should last around 10,000 opening and closing cycles. This means that you can expect the spring to break after about 14 years of use if you only open and close the garage once a day. Generally, springs wear out within five to seven years. New springs rarely break in a year. Springs may break due to age, rust, or because they are under too much pressure or tension.
It is possible for door springs to shrink slightly during the winter months when the temperature drops below a certain threshold, which puts extra strain on them and makes them more likely to break. All garage door springs will eventually fail, but proper maintenance can help extend their life and alert you when they are about to fail. If you plan to use your garage door more often, you should invest in a system with springs for 20,000 to 25,000 cycles. Biannual lubrication of metal parts that rub against each other can also help extend the life of springs. Additionally, garage door companies offer tune-up services that can help you get the most out of your doors and detect problems before they become disasters. Electric door openers should only lift what a person can lift with their hand.
For example, if a 9 x 7 foot door with a single row of windows weighs 135 pounds, it would have to be weighted so that a person can lift it with one hand. If you're considering replacing your garage door spring, you're probably wondering how long your new springs will last before they need to be replaced again. The normal wear and tear of opening and closing the door without stopping breaks them and, eventually, they will need to be replaced. This makes them a great option if you only have a single-car garage and are operating on a tight budget. Knowing how garage door springs work, how to fix them, or what causes them to break is valuable knowledge that every homeowner should have before they find themselves late for work because they can't get their car from the garage.
