Spring repair in Draper, Utah

Draper sits at roughly 4,495 feet, and the 94.8 annual freeze–thaw crossings that come with that elevation fatigue spring steel independently of how often the door runs. Each crossing contracts and expands the coil; the damage accumulates whether the door cycles twice a day or ten times.

There is a second cold effect: freezing temperatures make spring steel more brittle, so the fatigued spring picks the coldest lift of the day to fail. With 91% of Draper's freeze–thaw days packed into November through March, the failure season is not a mystery.

The housing vintage stacks on top — half the homes in Draper were standing by 1999, 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 Draper's 94.8 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: Sandy runs 93.1 freeze–thaw cycles and 5–7 years of spring life; Riverton runs 95.7 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, Draper holds 94.8 cycles at 4,495 ft with a 1999 median build year — the specific inputs behind every figure above.
