How to Replace a Broken Garage Door Spring


Garage doors play a vital role in providing security and convenience to homeowners. However, with time and usage, certain components, such as the garage door springs, may wear out or break.

Dealing with a broken garage door spring can be daunting, but with the right knowledge and tools, you can replace it yourself. This guide will walk you through the process step by step, ensuring a safe and successful replacement.

Understanding Garage Door Springs

Before diving into the replacement process, it’s essential to understand the two main types of garage door springs: torsion springs and extension springs.

Torsion springs are typically used in modern garage doors and are mounted above the door opening, while extension springs are mounted on either side of the door tracks. Both types store and release energy to help lift and lower the garage door.

Signs of a Broken Garage Door Spring

Identifying a broken garage door spring is crucial for timely repair. Some common signs include the door being unbalanced, difficulty in opening or closing the door, excessive noise during operation, or visible damage to the springs.

If you notice any of these signs, it’s likely that you have a broken spring that needs replacement.

Safety Precautions

Before starting the replacement process, safety should be your top priority. Garage door springs are under high tension and can cause serious injuries if mishandled.

It’s crucial to disconnect the power to the garage door opener and secure the door in a fully open position using clamps or pliers. Additionally, wearing protective gear, such as safety glasses and gloves, is highly recommended.

Tools and Materials Needed

To replace a broken garage door spring, you’ll need the following tools and materials:

  1. C-clamps or locking pliers
  2. Adjustable wrench
  3. Socket set
  4. Vice grips
  5. Safety glasses
  6. Gloves
  7. New garage door spring(s)
  8. Ladder

Step-by-Step Guide to Replacing a Broken Garage Door Spring

  1. Secure the door: Use C-clamps or locking pliers to secure the garage door in an open position.
  2. Release tension: Using an adjustable wrench or socket set, loosen and remove the set screws on the winding cone of the broken spring.
  3. Remove the broken spring: Slide the broken spring off the torsion tube and unwind it completely.
  4. Install the new spring: Slide the new spring onto the torsion tube and wind it tightly, following the manufacturer’s instructions.
  5. Reattach the cables: Connect the lift cables to the new spring and ensure they are properly seated on the cable drums.
  6. Test the door: Remove the clamps or pliers and test the door’s balance and smooth operation by manually opening and closing it a few times.
  7. Adjust as necessary: If the door is unbalanced or not operating smoothly, make small adjustments to the spring tension until the door functions properly.
  8. Repeat the process for extension springs: If your garage door has extension springs, follow a similar process, but be sure to disconnect the safety cables and remove the extension

spring pulleys before replacing the spring. 9. Lubricate moving parts: Apply a silicone-based lubricant to all moving parts of the garage door system, including the springs, rollers, and hinges, to ensure smooth operation. 10. Perform regular maintenance: Inspect the springs periodically for signs of wear or damage and lubricate them as needed.

Testing and Adjusting the Garage Door

After replacing the broken garage door spring, it’s crucial to test the door and make any necessary adjustments. Open and close the door several times to ensure it operates smoothly and is well-balanced. If you notice any issues, such as the door being unbalanced or making strange noises, consult a professional for further adjustments or repairs.

Common Mistakes to Avoid

While replacing a broken garage door spring, it’s important to avoid common mistakes that could compromise safety or the functionality of the door. Some mistakes to avoid include:

  1. Attempting the repair without proper knowledge or experience.
  2. Failing to secure the door properly before starting the replacement.
  3. Over-tightening or under-tightening the springs.
  4. Neglecting to wear safety gear during the replacement process.

Maintenance Tips for Garage Door Springs

To prolong the lifespan of your garage door springs and maintain optimal performance, consider the following maintenance tips:

  1. Regularly inspect the springs for signs of wear, such as rust, corrosion, or visible damage.
  2. Lubricate the springs and other moving parts of the door system at least twice a year.
  3. Test the door’s balance periodically by disconnecting the opener and manually operating the door.


Replacing a broken garage door spring may seem challenging at first, but with the right tools, knowledge, and safety precautions, it can be successfully accomplished. Remember to prioritize safety throughout the process and consult a professional if you encounter any difficulties. By following the step-by-step guide provided in this article, you can restore the functionality of your garage door and ensure smooth and secure operation for years to come.
