The Ultimate Guide to Fixing a Broken Garage Door Spring

Garage doors are a crucial part of our homes, offering both convenience and security. However, like any mechanical system, they can occasionally break down. One of the most common issues homeowners face is a broken garage door spring. In this comprehensive guide, we will delve into the nitty-gritty details of fixing a broken garage door spring, ensuring your garage door operates smoothly and safely.

Introduction to Garage Door Springs

Garage door springs play a vital role in the functionality of your garage door. They are responsible for balancing the weight of the door, making it easy to open and close. There are two main types of garage door springs: torsion springs and extension springs.

Torsion Springs

Torsion springs are mounted on a metal shaft above the garage door. When the door is closed, these springs are tightly wound. When you open the door, they unwind and create the necessary tension for a smooth operation.

Extension Springs

Extension springs are installed on the sides of the door and expand and contract to assist in lifting and lowering the door. They are generally used for lighter garage doors.

Identifying a Broken Garage Door Spring

Before you embark on the repair journey, it’s essential to identify whether your garage door spring is indeed broken. Here are some telltale signs:

  1. Uneven Door: If your garage door is uneven when closed or doesn’t close properly, it could be a sign of a broken spring.
  2. Loud Noise: A loud bang or snap when operating the door is a strong indicator of a broken spring.
  3. Difficulty Opening: If your garage door is suddenly much heavier and more challenging to open manually, a broken spring is likely the culprit.
  4. Visible Damage: Inspect the springs visually. If you notice any gaps, cracks, or signs of wear and tear, it’s time for a replacement.

Safety Precautions

Working on garage door springs can be dangerous, as they are under high tension. It’s essential to take safety precautions seriously. Here’s what you need to do:

  1. Release Tension: Before attempting any repairs, release the tension on the springs. This is a critical safety step.
  2. Use Proper Tools: Ensure you have the right tools for the job, including winding bars, clamps, and safety glasses.
  3. Wear Protective Gear: Protect yourself with gloves and eye protection.

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

Step 1: Gather Your Tools

Before you begin, gather all the necessary tools and materials, including:

  • Replacement springs
  • Winding bars
  • Clamps
  • Socket set
  • Safety glasses
  • Gloves

Step 2: Release the Tension

As mentioned earlier, releasing the tension is crucial for your safety. Use winding bars to unwind the old spring and relieve the tension. Make sure to do this carefully.

Step 3: Remove the Old Spring

Once the tension is released, you can safely remove the old, broken spring. Be cautious when doing this, as it may still have some residual tension.

Step 4: Install the New Spring

Carefully install the new spring in the same position as the old one. Make sure it is securely in place.

Step 5: Wind the Spring

Using the winding bars, wind the new spring to the appropriate tension. This is a critical step to ensure the proper functioning of your garage door.

Step 6: Test the Door

After the new spring is in place and wound correctly, test the garage door to ensure it opens and closes smoothly.

When to Call a Professional

Repairing a broken garage door spring can be a challenging and potentially dangerous task. If you are not confident in your abilities or encounter any issues during the process, it’s advisable to seek professional help. A skilled technician will ensure that your garage door operates safely and efficiently.


A broken garage door spring can be a frustrating problem, but with the right knowledge and tools, it’s a repair you can tackle yourself. However, always prioritize safety and consider seeking professional assistance if needed. By following these steps and guidelines, you can have your garage door back in working order, providing the security and convenience you need.
