Torsion Springs Sized, Wound and Balanced in Joliet
A torsion spring is rated in cycles, not in years, and one cycle means the door opens and shuts once. A common stock spring is built for around ten thousand of them, so the same part lasts fifteen years on a garage nobody uses and about five on a west-side house where the garage is the front door.

BH Garage Door replaces torsion springs across Joliet, on the narrow detached garages off the alleys behind the older streets and on the wide insulated doors in the Route 59 subdivisions. The spring gets measured against the door it has to lift, not guessed from the size of the opening.
What the Shaft Above Your Door Is Actually Doing
Above the opening runs a steel shaft carrying the spring, anchored at its middle to a bracket bolted through the header. Run the door and the shaft turns with it, unwinding the spring and paying cable off a drum at each end. Every bit of the lifting comes from that stored twist. The opener only steers the door and holds it; it was never built to carry the weight.
That is why a broken spring is not an opener fault even though the opener is what stops working. Keep pressing the button and you are asking a fractional-horsepower motor to drag a door that can weigh close to two hundred pounds. Gears strip, the chain jumps the sprocket, and a job that was springs becomes springs plus a gear kit.
Cycle Life, and When a High-Cycle Set Pays Off
Count how often your door runs. Two cars in and out, a school run, a trip to the store: a household on the west side reaches six or eight cycles a day without trying. At that rate a stock spring is at the end of its rated life long before the door itself is anywhere near worn out.
A high-cycle spring uses heavier wire on a larger diameter to produce the same lift with a much longer service life. It costs more up front and it is the sensible choice on a door that is the main way into the house. On a garage down the alley that gets used twice a week, it is money you do not need to spend, and we will say so.
Anchor Points in Older Joliet Garages
The centre bracket and the two end bearing plates take the entire torque of the spring, and they are only as good as what they are fastened to. Many garages on the older side of the city are stone or block with a timber header that has spent decades unheated and damp. Lag screws pull loose, the bracket creeps, and the shaft ends up running out of true.
So the header gets checked before a new spring goes on it. Where the timber has gone soft the answer is a backing plate or new blocking, not a longer screw into the same crumbled hole. Then the winding gets tested against the door itself. Halfway up with your hands off, it should sit still, and it should travel without one side arriving before the other.

Questions
Joliet questions about this job
There is one spring above my door and I have been told I need two. Is that upselling?
Not necessarily either way. A single spring is a legitimate design and plenty of doors are built that way. On a wide, heavy insulated door, two springs share the load, keep the shaft straighter and leave the door easier to lift by hand if one lets go. The technician will tell you what your door was engineered for and what changing it would involve.
Can a broken spring be re-wound instead of replaced?
No. A spring that has broken has reached the end of its fatigue life, and the steel is finished whether or not the rest of the coil looks intact. Winding more turns into a tired spring buys a door that lifts today and fails again soon, usually harder than the first time.
The spring is fine but the door feels heavier every winter. What is that?
Spring steel gives up a little torque as it gets cold, so a set already near the end of its life shows it first on a freezing morning in an unheated garage. It is a warning rather than a coincidence. A balance check tells you whether it needs the winding adjusted or the pair is simply due.
