Garage door spring replacement in Chattanooga typically runs $285–$485 for a standard residential door, parts and labor included. The exact price depends on spring type (torsion vs extension), whether you replace one or both, and the cycle rating you choose.
Scenic City Garage Doors gives you a flat-rate written quote on-site before any work begins, and we always replace springs in pairs so the second one doesn't break next month.
**Single torsion spring replacement:** $245–$345 installed.
**Pair of torsion springs (recommended):** $345–$485 installed.
**Extension springs (one-car door, pair):** $185–$285 installed.
**High-cycle 20,000+ rating upgrade:** add $65–$95 per spring (doubles spring lifespan to 12–15 years).
**After-hours / emergency spring replacement:** same flat-rate. No nights/weekends surcharge.
Both springs on a two-spring door went through the same cycles in the same humidity. When one snaps, the other is at end-of-life—usually within months. Replacing both costs less than two service calls and rebalances the door correctly.
Door weight (heavier insulated or wood doors need larger-gauge springs), spring cycle rating (10K vs 20K vs 30K), torsion vs extension system, single-spring vs double-spring, and whether the cables and drums also need replacement (often the case on 12+ year old doors).
