Why do garage door springs snap on cold Nashville mornings?
A torsion spring is a tightly wound steel coil that stores enough energy to lift your door. Every open and close uses up part of its rated life. Cold makes steel less forgiving. On a morning in the 20s, a spring that's already near the end of its life is more likely to crack, and broken springs often turn up right after a cold front.
Nashville doesn't stay frozen, though. It swings above and below 32 degrees again and again through the winter, and summer humidity rusts the coils the rest of the year. Rust pits become weak spots, and temperature swings keep working on them. That combination is why spring breaks tend to cluster between December and February.
What if my garage has two or three doors?
Many newer homes in Franklin, Brentwood, Nolensville, and Spring Hill have three-car garages, often with a double door and a single door, or three singles. Each door has its own springs. They were usually installed together, they've made a similar number of cycles, and they live in the same temperatures.
When one spring breaks, we check the springs on the other doors too. We'll tell you honestly if they look worn so you can decide whether to handle them now or later. On a double door with one spring, we may recommend converting to two springs so the load is shared.
Is it safe to open the door after a spring breaks?
No. With a broken spring, the door's full weight is on the opener and cables. Running the opener can strip its gears, snap a cable, or pull the door off track. Pulling the emergency release can let the door drop.
Never try to unwind or replace a torsion spring yourself. It's under extreme tension, and the winding process causes serious injuries every year. Leave the door closed, park outside, and call us. If a cable broke too, our cable repair page explains what that means.
What happens during a spring replacement in Nashville?
We secure the door, remove the broken spring, and check the door's weight and balance. Then we install springs sized to your door, inspect the cables, drums, center bearing, and rollers, and lubricate moving parts with a product that won't gum up in the cold. Finally, we test the opener's force and reverse settings.
On older doors in Madison or Belle Meade, cables and bearings may be worn from decades of use. If they are, we'll show you before replacing anything. Cost depends on spring type and size, whether we replace one or both, and the condition of the cables and rollers. We'll quote on site.
