You heard a sharp bang from the garage, and now the opener hums for a second and gives up. The door lifts a few centimetres at most, then settles back down as if something very heavy is holding it in place.
Every spring is built for a number of open-close cycles, and replacement is a natural moment to choose that number deliberately. A standard residential spring is commonly rated around ten thousand cycles; a family that opens the door six times a day uses those up in a few years. Higher-cycle springs use heavier wire and a longer coil to produce the same force with less stress on the steel, so they last proportionally longer. The technician can explain the trade-off and fit whichever option suits the household's use of the door, then wind and balance it accordingly.

Scene 1
Doors are set up in several ways, and the replacement has to match. The technician notes whether there is one spring or two, whether the shaft is a single piece or two halves joined by a coupler, and what the shaft diameter is. Drum type is read from the drums themselves: standard-lift drums for a normal ceiling, high-lift or vertical-lift drums where the door rises well above the opening, or a rear-mounted assembly in a low-headroom garage. Track radius and headroom are measured because they change how many turns the spring needs and which drums it must work with.
Scene 2
On a two-spring door the springs are installed as a set: one left-wound and one right-wound, mirrored on either side of the centre bracket, with matching wire size, diameter and length so each carries half the load. Both stationary cones bolt to the centre bracket and both winding cones face outward. The technician winds each spring the same number of quarter turns, alternating between them, so the shaft is never loaded unevenly. Once both are set, the door is balanced and tested as one system. Equal springs mean equal wear, so the pair reaches the end of its life together rather than one after the other.
Scene 3
The new spring has been set for the door as it is today, and the seasons are part of its life. Cold mornings make steel and grease a little stiffer, so the door may feel marginally slower in deep winter while still balanced; lubrication in autumn helps. Slush and road salt carried in on tires settle on the bottom brackets and cable ends, so a rinse and a light spray in spring slow corrosion where the cables anchor. Summer humidity is easier on hardware but rewards a dry, clean track. Small seasonal habits like these let the spring reach its full rated cycle count.

Balance means the spring is holding almost exactly the door's weight, so the door neither flies up nor slams down and the opener only guides it. It is tested by releasing the opener, lifting the door to about waist height and letting go: a balanced door stays there. The technician fine-tunes in quarter turns of the spring until the door holds at several heights and travels evenly on both sides.
The spring is chosen from measurements rather than appearance. The technician records the door's width, height and weight, the drum type and track lift, and reads the old spring's wire size, inside diameter, length and wind direction. Those inputs together determine the spring that will balance the door. The choice is confirmed on the spot by lifting the finished door by hand and feeling it hold at mid-height.
Not necessarily, and that is fine. The paint colour on the winding cone or coil is a code that identifies wire size and wind direction, and different suppliers use their own schemes, so a matched replacement can carry a different colour than the spring it replaces. What matters is that the wire size, diameter, length and wind direction suit the door's weight and height, which is confirmed by the balance test.
