Spring repair in Taylorsville, Utah

At 4,265 feet, Taylorsville takes 84.4 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 Taylorsville's calls track its winter: 94% of the year's freezing crossings land between November and March.

half the homes in Taylorsville were standing by 1978, which makes original springs the exception; doors here are typically on their second or third set. The exception is exactly the door to test, because it is far past the 5–7 years this climate allows.

The 25,000-cycle upgrade adds $80 to $150 to a replacement and multiplies expected life by roughly 2.5. At Taylorsville's 84.4 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.

For context around Taylorsville: Murray runs 85.9 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 Kearns runs 88.4 freeze–thaw cycles and 5–7 years of spring life.

This page runs on Taylorsville's numbers (84.4 freeze–thaw cycles, 1978 median build, 4,265 ft of elevation) — close to the neighbours', never identical, which is exactly the point of measuring per city.
