Garage Door Spring Replacement in Charlotte, NC
Springs do the actual lifting. Your opener only guides the door. When a spring breaks, the door becomes its full dead weight — often 150 to 400 pounds — and nothing else on the door works correctly until the counterbalance is restored.

Symptoms we hear about most
You heard a loud bang from the garage
A torsion spring releasing its tension is startling and often mistaken for something falling.
A visible gap in the coil
Look at the spring above the door. A two-inch separation in the middle of a coil is a broken spring.
The door is suddenly extremely heavy
With the opener released, a balanced door should hold at waist height. A door that slams down has no working counterbalance.
The opener strains, hums or reverses
The motor is trying to lift weight the springs should be carrying.
The door rises a few inches then stops
The opener hits its force limit almost immediately.
What causes it
- Cycle life exhausted — a standard 10,000-cycle spring is roughly 7 to 12 years of normal use
- Undersized springs for the door's actual weight, often after an insulated door replaced a lighter one
- Rust and moisture pitting the coil, which shortens life considerably
- One spring replaced alone previously, leaving a mismatched pair
How Garage Justice handles it
- 1Measure the existing spring: wire diameter, inside diameter, overall length and wind direction
- 2Weigh or calculate the door's load so the replacement spring matches the door, not just the old part
- 3Replace with controlled winding bars and proper tensioning — never improvised tools
- 4Inspect cables, drums, bearings and the center bearing plate while the tension is off
- 5Rebalance, then test that the door holds position manually and that the opener runs without strain
Your options
Standard-cycle replacement
Matches original specification. Appropriate for lower-use doors.
High-cycle upgrade
Heavier wire and more cycles for doors used many times a day — often the better value on a primary-entry garage.
Replace the pair
On a two-spring door of similar age we usually recommend replacing both. The second spring has the same cycles on it and will typically fail soon after.
Extension spring systems
Older doors may use extension springs alongside the tracks. These require intact safety containment cables, which we verify or install.
What affects the price
We don't publish a fixed price list for this work, because the honest answer depends on your door. These are the factors that actually move the number:
- Single spring versus a matched pair
- Wire size and cycle rating of the replacement
- Door weight and whether it is insulated
- Condition of cables, drums, bearings and the center bearing plate
- Whether cables came off the drums when the spring failed
Why not to leave it
Torsion springs hold enough stored energy to cause serious injury, and the winding process is where most DIY spring injuries happen. We do not publish spring replacement instructions, and we do not recommend attempting it with hardware-store tools. If your spring is broken, leave the door down and disconnect the opener so no one tries to force it.
Local context in Charlotte
Most newer Charlotte-area subdivisions use double doors on torsion systems with builder-grade springs installed at the same time as the homes. Those neighborhoods tend to see spring failures in clusters, which is why a neighbor's broken spring is often a good reason to have yours inspected.

Spring Replacement FAQs
How do I know if my garage door spring is broken?
Look at the spring above the door for a visible gap in the coil, and try lifting the door by hand with the opener released. A broken spring makes the door feel extremely heavy and often follows a loud bang from the garage.
Can I open my garage door with a broken spring?
You should not. The door is carrying its full weight with nothing counterbalancing it, so it can drop quickly and it can damage the opener. Park outside, leave the door closed, and have the spring replaced.
Do I need to replace both garage door springs?
Not always, but usually it makes sense. On a two-spring door both springs have accumulated the same number of cycles, so replacing only the broken one often means a second service call within a year. We show you the condition of both and let you decide.
How long does spring replacement take?
A straightforward torsion spring replacement on a residential door is typically completed in about an hour, including rebalancing the door and testing the opener.
