Mastering Garage Door Spring Repair: Everything You Need to Know

Garage Door Spring Repair


A functioning garage door is a crucial part of home security and convenience. However, when the springs break, it can lead to significant inconveniences and potential safety hazards. Understanding how to repair these springs can save time and money, ensuring your garage door operates smoothly and safely. This guide delves into the complexities of garage door spring repair, providing valuable insights and practical advice for homeowners. Whether you are a DIY enthusiast or looking to understand more before calling a professional, this comprehensive guide will equip you with the knowledge to tackle garage door spring issues.

Understanding Garage Door Springs

Before diving into the repair process, it’s essential to understand the role of garage door springs. These springs counterbalance the garage door’s weight, making it easy to open and close. There are two primary types of garage door springs: torsion springs and extension springs.

Torsion Springs are located above the garage door and twist to create tension. They are known for their durability and are typically used in modern garage door systems.

Extension Springs, on the other hand, are mounted on either side of the Door and extend when the Door is closed. While they are more common in older systems, they are still used today, especially in lighter garage doors.

Knowing the type of spring your garage door uses is the first step in mastering garage door spring repair. Each type requires different tools and techniques for repair and replacement.

Signs Your Garage Door Springs Need Repair

Recognizing the signs of worn-out or broken garage door springs can prevent further damage and potential safety risks. Here are some common indicators that your garage door springs may need attention:

  1. The Garage Door Won’t Open: If your garage door doesn’t budge or struggles to open, it could be due to a broken spring.
  2. Visible Gaps in Springs: A torsion spring gap indicates it is broken.
  3. Door Closes Too Quickly: The springs might not provide the necessary tension if the door slams shut instead of closing smoothly.
  4. Crooked Door: An uneven door suggests that one of the springs is not functioning correctly when opening or closing.
  5. Loud Bang: A loud noise like a gunshot indicates a spring has snapped.

Safety Precautions

Garage door spring repair can be dangerous due to the high spring tension. Here are some safety tips to keep in mind:

  2. Use the Right Tools: To avoid mishaps, ensure you have the correct tools, such as winding bars for torsion springs.
  3. Disconnect the Opener: Disconnect the garage door opener to prevent accidental activation during repair.
  4. Work with a Partner: Having someone assist you can make the process safer and more manageable.
  5. Follow Manufacturer Instructions: Adhere to the instructions provided by the garage door manufacturer for your particular model.

Step-by-Step Guide to Garage Door Spring Repair

Identifying the Type of Spring

Before starting any repair work, identify whether your garage door uses torsion or extension springs. This will determine the specific steps and tools required for the repair.

Preparing for the Repair

  1. Disconnect the Opener: Ensure the garage door opener is unplugged to prevent any accidental operations.
  2. Secure the Door: Use C-clamps or locking pliers to secure the Door, preventing it from moving while you work.

Replacing Torsion Springs

  1. Release the Tension: Use winding bars to release the springs’ tension carefully. Insert a winding bar into the winding cone and slowly loosen the screws.
  2. Remove the Old Springs: Remove the old springs by unscrewing them from the central bracket once the tension is released.
  3. Install the New Springs: Attach the new springs to the central bracket and tighten the screws. Ensure the springs are wound in the correct direction.
  4. Tighten the Springs: Use the winding bars to tighten the springs to the specified tension. This is a critical step, as improper tension can cause the Door to malfunction.
  5. Test the Door: Once the new springs are installed, remove the clamps and test the Door’s operation. Make any necessary adjustments to ensure smooth operation.

Replacing Extension Springs

  1. Release the Tension: Open the garage door fully to release the tension in the extension springs. Secure the Door with C-clamps.
  2. Remove the Old Springs: Disconnect the safety cables and remove the old springs from the brackets.
  3. Install the New Springs: Attach the new springs to the brackets and reattach the safety cables. Ensure the springs are securely fastened.
  4. Test the Door: Remove the clamps and test the Door’s operation. Adjust the tension if necessary to ensure smooth and balanced operation.

Balancing the Door

After replacing the springs, it is crucial to balance the garage door to ensure it operates correctly. Here’s how to balance your garage door:

  1. Disconnect the Opener: Unplug the garage door opener to allow for manual operation.
  2. Lift the Door Manually: Lift the Door halfway and let go. If the Door stays in place, it is balanced. If it moves up or down, you must adjust the tension in the springs.
  3. Adjust the Tension: Use the winding bars or an adjustable wrench to adjust the tension in the springs until the Door remains in place when lifted halfway.

When to Call a Professional

While many homeowners can handle minor garage door spring repairs, some require professional intervention. Here are some scenarios where calling a professional is advisable:

  1. Lack of Experience: If you are uncomfortable or experienced with mechanical repairs, it’s best to call a professional.
  2. Complex Repairs: Professionals should handle complicated issues, such as multiple broken springs or damaged cables.
  3. Safety Concerns: If unsure about the safety procedures, do not attempt the repair yourself.
  4. Specialized Tools: Some repairs require specialized tools not commonly available to homeowners.

Choosing the Right Professional

When selecting a professional for garage door spring repair, consider the following factors:

  1. Experience and Reputation: Choose a company with a solid track record and positive customer reviews.
  2. Licensing and Insurance: Ensure the company is licensed and insured to protect against potential damages or injuries.
  3. Estimates and Pricing: Get multiple estimates to compare prices and services offered.
  4. Warranty: Opt for a company that offers a warranty on their repair work to guarantee quality and reliability.

  5. Neglecting Regular Maintenance: Skipping regular maintenance can shorten the lifespan of your garage door springs.


Q: How long do garage door springs typically last?

A: The lifespan of garage door springs depends on their quality and usage. Generally, torsion springs last between 15,000 to 20,000 cycles, while extension springs last around 10,000 cycles. Regular maintenance can help extend their lifespan.

Q: Can I replace just one spring, or should both be replaced?

A: It’s recommended that both springs be replaced, even if only one is broken. Springs are typically installed simultaneously; if one fails, the other is likely to follow soon after. Replacing both ensures balanced tension and optimal performance.

Q: Is it safe to repair garage door springs myself?

A: While some homeowners successfully repair their garage door springs, it can be dangerous due to the high tension involved. If you are not experienced with such repairs, hire a professional to avoid injury and ensure proper installation is safer.

Q: How can I tell if my garage door springs are balanced correctly?

A: To check if your springs are balanced, disconnect the garage door opener and lift the Door halfway. If the Door stays in place, the springs are balanced. If it moves up or down, the springs need adjustment.

Q: What should I do if my garage door spring breaks suddenly?

A: If a spring breaks suddenly, do not attempt to open or close the garage door. Disconnect the opener, secure the Door, and call a professional to safely assess and repair the springs.


Mastering garage door spring repair is a valuable skill that can enhance the functionality and safety of your garage door. By understanding the types of springs, recognizing signs of wear, and following the proper repair steps, you can address many common issues independently.
