Spring repair in Grantsville, Utah

At 4,298 feet, Grantsville takes 93 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 Grantsville's calls track its winter: 94% of the year's freezing crossings land between November and March.

Add the construction dates: half the homes in Grantsville were standing by 1998, meaning original springs across whole subdivisions are hitting their first Grantsville-climate failure window together.

The 25,000-cycle upgrade adds $80 to $150 to a replacement and multiplies expected life by roughly 2.5. At Grantsville's 93 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 Grantsville: Tooele runs 102.9 freeze–thaw cycles and 5–7 years of spring life; Magna runs 84.5 freeze–thaw cycles and 5–7 years of spring life; and Herriman runs 102.2 freeze–thaw cycles and 5–7 years of spring life.

This page runs on Grantsville's numbers (93 freeze–thaw cycles, 1998 median build, 4,298 ft of elevation) — close to the neighbours', never identical, which is exactly the point of measuring per city.
