Professional Garage Door Spring Replacement — Torsion & Extension

A broken garage door spring is the most common and dangerous garage door failure. Springs carry the full weight of your door, often 150 to 300 pounds. Dubya Garage Doors provides fast, safe spring replacement across the SC Midlands.

Why Garage Door Springs Break

Garage door springs have a limited lifespan measured in cycles. One cycle equals one open-and-close sequence. Most standard springs are rated for 10,000 cycles. When a spring reaches the end of its cycle life, it breaks, often with a loud bang that sounds like a gunshot. Other factors that accelerate spring failure include:

• Temperature extremes and humidity (common in South Carolina)
• Rust and corrosion from lack of lubrication
• Incorrect spring size or improper installation
• Frequent daily use (more than 4 cycles per day)

Types of Garage Door Springs

Torsion Springs

Torsion springs are mounted horizontally on a shaft above the garage door opening. They use torque (twisting force) to lift the door. Torsion springs are the modern standard because they provide smoother, more controlled operation and last longer than extension springs. Most residential garage doors use one or two torsion springs.

Extension Springs

Extension springs are mounted vertically on both sides of the door opening. They stretch and contract to provide lifting force. While effective, extension springs require safety cables to prevent them from becoming dangerous projectiles if they break. Extension springs are common on older garage door systems.

Our Spring Replacement Process

1. Safety First: We secure the door in the closed position and disconnect the opener before beginning any work on the springs.
2. Measurement and Selection: We measure the existing springs and select the correct replacement based on door weight, height, and track configuration.
3. Professional Removal: Using proper winding bars and safety equipment, we carefully release the tension on the old springs and remove them.
4. Installation and Winding: New springs are installed and wound to the manufacturer's specifications for your specific door.
5. Balance Testing: We test the door balance by disconnecting the opener and manually lifting the door to the halfway point. A properly balanced door should stay in place.
6. Full System Check: We test the complete system including the opener, safety sensors, and auto-reverse function.

Why Replace Both Springs at Once?

When one spring breaks, the other spring has the same age, wear, and cycle count. It is likely to break soon as well. Replacing both springs at the same time saves you the cost of a second service call and ensures balanced operation. We always recommend replacing springs in pairs.

High-Cycle Spring Upgrades

If you are tired of replacing springs every 7 to 10 years, ask about our high-cycle spring options. These premium springs are rated for 25,000 to 50,000 cycles and can last 15 to 20 years or more. The upfront cost is slightly higher, but the long-term savings are significant.
