Spring repair in South Jordan, Utah

At 4,495 feet, South Jordan takes 93.1 freeze–thaw crossings a year, and every one of them works the spring steel — contraction, expansion, repeat — whether or not the door moves at all. Usage adds cycles; the climate adds fatigue on its own clock.

Brittleness is the accomplice — cold steel fractures where warm steel bends, which is why the break so often happens on the first morning lift, and why South Jordan's calls track its winter: 91% of the year's freezing crossings land between November and March.

The housing vintage stacks on top — half the homes in South Jordan were standing by 2003, so a wave of original builder-grade springs is arriving at this climate's 5–7-year limit about now.

The 25,000-cycle upgrade adds $80 to $150 to a replacement and multiplies expected life by roughly 2.5. At South Jordan's 93.1 cycles a year of thermal fatigue, that arithmetic tilts firmly toward the upgrade — it converts a 5-to-7-year spring into one that outlasts most ownerships, and it avoids paying the call-out twice.

Fit them as a matched pair, sized to the door's measured weight — in this climate an undersized bargain spring is the shortest-lived spring of all.

The measurements shift town by town: Riverton runs 95.7 freeze–thaw cycles and 5–7 years of spring life; West Jordan runs 90.5 freeze–thaw cycles and 5–7 years of spring life; and Midvale runs 88.2 freeze–thaw cycles and 5–7 years of spring life.

This page runs on South Jordan's numbers (93.1 freeze–thaw cycles, 2003 median build, 4,495 ft of elevation) — close to the neighbours', never identical, which is exactly the point of measuring per city.
