Torsion Springs Specified to the Door, Not the Shelf
A torsion spring is a consumable part with a printed specification. It is rated in cycles, and a cycle is one open and one close. Nothing about it is generic: wire diameter, inside diameter, wound length and wind direction all have to be right for the door hanging under it, and if any one of them is wrong the door has been fighting itself since the day it was fitted.

Pulling a broken spring off a shaft is straightforward. Deciding what goes back on is where the next several years get decided, and on Waukegan garages the answer is often not what came off.
Reading the Spring That Failed
Before anything comes off the shaft, the old spring gets measured. Wire diameter is taken across a set number of coils, because a single-coil measurement is easy to get wrong. Inside diameter is read off the cone. Overall wound length gets measured on the relaxed side of the break, and wind direction is read from the way the coil turns at the end.
Where the spring is too corroded to read, and near the lakefront that happens, the door itself becomes the reference. Weighing it is slower than copying a part number, but it produces a spring that is right rather than one repeating a previous mistake.
The Spring That Was Never Right for the Door
This is common enough in Waukegan to be worth calling out. A detached garage gets a new door at some point in the last twenty years, usually a heavier insulated one, and the existing spring stays on the shaft because it was not broken that day. The door has been overweight ever since.
You can see the symptoms without any tools. The opener labours on the way up and slams a little on the way down. Released from the opener at waist height, the door sinks rather than holding. That door will go through springs, then cables, then a gear in the opener head, in that order, and replacing the spring with an identical undersized one just restarts the clock.
Cycle Ratings and When to Buy Up
A standard residential spring is wound for roughly ten thousand cycles. For a household that opens the door a couple of times a day that is years of service. For a house where the garage is the door everybody actually uses, and the west side of Waukegan has plenty of those, the same spring is used up considerably faster.
Higher-cycle springs are wound from heavier wire over a longer body, doing the same lifting work with less stress in the steel. They take up more shaft, which is the limit on narrow single-car openings. Where the shaft allows it and the door works hard, ask for them. Where the door opens twice a week, do not bother.
Once the new spring is on, it gets wound to the calculated turns and then the door gets tested against it. Correct tension means the door holds position anywhere you leave it by hand. That test, not the winding count, is what says the job is finished.

Questions
Waukegan questions about this job
How many cycles do I actually get out of a torsion spring?
A standard spring is wound for about ten thousand open-and-close cycles. Count how many times your door runs on a normal day and divide. A door used four times a day gets through them far quicker than the same spring on a garage opened twice a week.
Can a torsion spring be re-tensioned instead of replaced?
A spring that has lost some tension but is otherwise sound can be adjusted, and that is a normal part of a balance correction. A spring with a visible gap in the coil is broken and cannot be wound back into service.
My garage got a new door years ago on the old spring. Does that matter?
It matters a lot if the new door is heavier, which it usually is. An undersized spring makes the opener carry weight it was never meant to lift. If your door sinks when you release it halfway up, that is what you are looking at.
