Spring repair in Herriman, Utah

Elevation is the quiet driver: Herriman's 4,987 feet buy it 102.2 freezing crossings a year, and each one flexes the coil like a small unpaid cycle. A door used twice a day and a door used ten times age differently — but both springs live in the same Herriman winter.

Cold adds a second effect: low temperature reduces the fracture toughness of spring steel, so a fatigued spring is likeliest to let go on the first lift of a freezing morning. That is when Herriman spring calls cluster — 90% of the year's freeze–thaw days here fall between November and March.

Housing age sharpens it: half the homes in Herriman were standing by 2009, which puts a large share of original builder-grade springs inside their first failure window right now.

Upgrading to 25,000-cycle springs costs $80 to $150 more and roughly multiplies life by 2.5. With 102.2 freeze–thaw cycles a year working on the steel in Herriman, the upgrade turns a 5–7-year spring into one most owners never replace again — one invoice instead of two.

Whatever the rating, it goes on as a pair and it gets sized to the actual door weight. Cut-price undersized springs fail fastest exactly where winters are hardest.

The measurements shift town by town: Riverton runs 95.7 freeze–thaw cycles and 5–7 years of spring life; Bluffdale runs 97.6 freeze–thaw cycles and 5–7 years of spring life; and South Jordan runs 93.1 freeze–thaw cycles and 5–7 years of spring life.

Against that backdrop, Herriman holds 102.2 cycles at 4,987 ft with a 2009 median build year — the specific inputs behind every figure above.
