Spring repair in Cedar Hills, Utah

Elevation is the quiet driver: Cedar Hills's 4,889 feet buy it 102 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 Cedar Hills 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 Cedar Hills spring calls cluster — 91% of the year's freeze–thaw days here fall between November and March.

The housing vintage stacks on top — half the homes in Cedar Hills were standing by 2002, so a wave of original builder-grade springs is arriving at this climate's 5–7-year limit about now.

Upgrading to 25,000-cycle springs costs $80 to $150 more and roughly multiplies life by 2.5. With 102 freeze–thaw cycles a year working on the steel in Cedar Hills, 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.

For context around Cedar Hills: Highland runs 102.1 freeze–thaw cycles and 5–7 years of spring life; Alpine runs 100.1 freeze–thaw cycles and 5–7 years of spring life; and Pleasant Grove runs 99 freeze–thaw cycles and 5–7 years of spring life.

This page runs on Cedar Hills's numbers (102 freeze–thaw cycles, 2002 median build, 4,889 ft of elevation) — close to the neighbours', never identical, which is exactly the point of measuring per city.
