Torsion Springs Wound to the Door You Actually Have
A torsion spring is not a part you swap out on its own. It is one piece of an assembly - shaft, center bearing plate, two cones, two drums and the cables wound onto them - and all of those pieces have to agree with each other before the door will sit still at knee height.

BH Garage Door replaces torsion springs across Highland Park, from single detached garages behind the older houses to three-bay openings on newer builds. Most of this work is booked and finished the same day.
One spring or two across a wide opening
Plenty of wide doors here were hung with a single torsion spring because the numbers worked on paper. They do work, right up until the day that one spring breaks and the door is dead weight. Two springs sharing the load each run at lower stress, and when one fails the second usually holds enough that the door does not come down hard.
On a three-bay garage the shaft can run twelve or fourteen feet with a coupler in the middle, and that length flexes. If the center bearing plate is not solid in the header, the whole assembly walks under load and the cables start climbing the drums unevenly. We check that plate before anything gets wound.
What the old spring tells us, and what it leaves out
Wire diameter, inside diameter and length can be measured off the failed spring, and wind direction reads off the cone. That gets us close. What it does not tell us is what the door weighs, and on a Highland Park door with a cedar overlay or a full-view glass section, the original spring may have been sized for the bare door before any of that went on.
So the door gets weighed. It comes off the opener, a scale goes under the bottom section, and that number sets the wire size and the number of turns. Matching an undersized spring exactly just books the next breakage.
Winding, set screws and the room over the bay
Winding is done with proper bars, a quarter turn at a time, and the set screws are torqued down onto the flats of the shaft rather than onto bare round steel. Screws that are left loose let the cone creep, and the door drifts out of balance within weeks.
Cycle rating is a choice you get to make. A standard spring is rated somewhere around ten thousand opens and closes. Households that use the garage as the everyday entrance get through that faster than the calendar suggests, and on a heavy door the bang of a break is harder on everything around it - worth a thought where there is a bedroom or a bonus room directly above.

Questions
Highland Park questions about this job
There is a clean gap in the coil above my door but it still lifts a little. Can I keep using it?
No. That gap means the spring has broken, and whatever lift is left is coming from the opener motor. Every cycle from here risks the gear, the cables and the door. Pull the release cord and leave the door down.
My door has one spring. Can it be converted to two?
Usually, if the shaft length and the header allow it. It is a common upgrade on wide doors around here - lower stress on each spring, and a door that does not go completely dead the moment one lets go.
Do both springs get replaced when only one broke?
On a two-spring door, yes. They went on together and have taken the same cycles, so the survivor is not far behind. Replacing one leaves the door unbalanced and books a second visit.
