Spring Replacement in St. Louis
Same-day torsion and extension spring replacement.
Garage door springs do all the heavy lifting — and they're the #1 thing that fails. When they snap, your door is dead weight (often 150–400 lbs). We replace torsion and extension springs the same day, using high-cycle springs rated for 2–3x the lifespan of builder-grade parts.
Common Causes
- Normal wear after 7,000–10,000 cycles
- Rust from Missouri humidity
- Improperly sized spring from prior installer
- Sudden temperature swings (common in St. Louis winters)
Single torsion spring: $200–$300. Dual spring replacement (recommended): $300–$450. Extension springs: $180–$280. High-cycle upgrade adds $50–$100 but doubles lifespan.
Most spring replacements take 60–90 minutes from arrival to test.
