What you're actually paying for
A garage door spring stores enough energy to lift a 150–300 lb door by hand. When it breaks, the opener can't do the job alone, and the door becomes unsafe to operate. Replacement covers the spring itself, the labor to wind and balance it correctly, and a safety check of the cables, drums, and bearings that work alongside it.
Pricing starts at $335 per spring plus labor. The spread above that comes from the spring tier (higher cycle ratings last longer), whether one or both springs are being replaced, and whether related parts — cables, bearings, drums — also need attention after a hard break.
Should you replace one spring or both?
On a two-spring door, both springs were installed at the same time and have taken nearly identical wear. When one fails, the other is usually close behind. Replacing only the broken spring almost always means a second service call — and a second trip charge — within months.
Replacing both at once means one trip, one balance reset, and a door that operates evenly. That's why most Tucson techs recommend it, and why we quote both options in writing so you can decide.
Why Tucson's climate matters
Springs are cycle-rated, not time-rated — they wear from winding and unwinding, and from temperature swings that fatigue the steel. Across Oro Valley, Marana, and the Catalina foothills, a 30°F+ daily range accelerates that fatigue. Most builder-grade springs in NW Tucson fail right at their rated cycle count, not beyond it.
- Builder-grade springs: ~10,000 cycles (about 5–7 years of typical use)
- Upgraded high-cycle springs: designed to outlast the door itself
- Higher cycle ratings cost more up front but reset the clock far longer
How to spot an honest quote
A trustworthy quote is in writing before any work starts, names the spring tier, and doesn't bait-and-switch you with a low phone price that balloons onsite. Be cautious of quotes that won't commit to a number, or that push a full door replacement for a single broken spring.
