Mastering Garage Spring Repair: A Step-by-Step Guide

Garage Spring Repair

Garage door springs play a crucial role in the smooth operation of your garage door. They counterbalance the weight of the door, making it easier to open and close. When a spring breaks or wears out, it can render your garage door inoperable. This guide provides a detailed, step-by-step process for repairing garage springs safely and effectively.

Understanding Garage Door Springs

Types of Garage Door Springs

There are two main types of garage door springs: torsion springs and extension springs.

  • Torsion Springs: These are mounted above the garage door and use torque to lift the door.
  • Extension Springs: These are found on either side of the door and stretch to provide the force needed to open the door.

Signs of a Broken Spring

A broken garage door spring can be identified by the following signs:

  • The door won’t open or close.
  • The door is extremely heavy to lift manually.
  • There is a visible gap in the spring.
  • The door opens unevenly.

Tools and Materials Needed


  • Safety Glasses
  • Gloves
  • Wrenches
  • C-Clamps
  • Winding Bars (for torsion springs)
  • Pliers


  • Replacement Springs
  • Lubricant
  • Ladder

Safety Precautions

Wear Protective Gear

Always wear safety glasses and gloves to protect yourself from any flying debris or sharp edges.

Disconnect the Opener

Before starting any repair, disconnect the garage door opener to prevent accidental activation.

Use the Right Tools

Using the correct tools, especially for winding and unwinding torsion springs, is essential for your safety.

Step-by-Step Guide to Garage Spring Repair

Step 1: Identify the Type of Spring

Determine whether your garage door uses torsion or extension springs. This will dictate the repair process.

Step 2: Secure the Door

Use C-clamps to secure the garage door in place. This prevents the door from moving while you work on the springs.

Step 3: Release the Tension (Torsion Springs)

For torsion springs, use winding bars to carefully unwind the tension. Insert the bars into the winding cone and slowly turn to release the tension. Be cautious, as the springs are under high tension.

Step 4: Remove the Broken Spring

Once the tension is released, remove the broken spring. For extension springs, disconnect the safety cables and remove the spring from the brackets.

Step 5: Install the New Spring

Install the new spring by reversing the removal process. For torsion springs, ensure you wind the new spring with the same number of turns as the old one. For extension springs, reattach the safety cables and secure the spring to the brackets.

Step 6: Test the Door

After installing the new spring, remove the C-clamps and test the door. Open and close it several times to ensure it operates smoothly. Adjust the tension if necessary.

Maintenance Tips for Garage Door Springs

Regular Inspections

Inspect your garage door springs regularly for signs of wear and tear. Catching problems early can prevent more significant issues.


Apply a garage door lubricant to the springs every few months. This reduces friction and helps prolong the life of the springs.

Balance Check

Periodically check the balance of your garage door. Disconnect the opener and lift the door manually. It should stay in place when lifted halfway. If it doesn’t, the springs may need adjustment.

When to Call a Professional

Complex Repairs

If you are uncomfortable with any part of the repair process or if the springs are severely damaged, it’s best to call a professional. They have the expertise and tools to handle the job safely.

High-Tension Springs

Working with high-tension springs, especially torsion springs, can be dangerous. Professional technicians are trained to handle these components safely.


Repairing garage door springs is a task that requires careful attention to detail and a focus on safety. By following this step-by-step guide, you can effectively replace broken springs and maintain the smooth operation of your garage door. Remember to perform regular maintenance and inspections to keep your garage door in top condition. When in doubt, don’t hesitate to seek professional assistance.
