Here is a picture of a broken spring that we serviced in Delta. If you look just above the ladder you can see it is in two pieces. Part of the spring is completely detached on the one end. This is a single garage door therefore only requires one spring. Double garage doors require two springs and will require both to be replaced even if only one is broken. Below is a before and after picture in 20/20, which will help you to see the break and then how it is supposed to look when fixed.
