The garage door plays a crucial role in many households, not only as an entry point for vehicles but frequently as an alternate access point and storage area. One of its most essential parts is the springs, which facilitate the frictionless opening and closing of the garage door. With time, these springs deteriorate and require replacement. While this task is typically recommended for professionals because of the associated hazards, for those proficient in undertaking DIY tasks, this guide seeks to provide an extensive explanation of how to substitute garage door springs.

Let's get started!

Understanding the Role of Springs

Garage door springs counterbalance the door's weight, facilitating its manual lift or operation by an opener. Without these springs, the immense weight of the door would make it an arduous task for an individual to lift.

Types of Garage Door Springs

There are primarily two types of garage door springs:

  • Torsion Spring: Positioned above the garage door, they operate by winding and unwinding precisely, anchored to a metal shaft, and utilizing a winding cone to set the tension. As the door lowers, cables attached to the bottom corners of the door cause the garage door torsion springs to wind up, creating stored energy. When the door is opened, this stored energy assists in lifting the door.

  • Extension Springs: Situated on both sides of the garage door, they stretch and retract as it maneuvers, supplying the essential counterbalance.

Note: Each type has its replacement procedure; this article will cover both.

Preparing for the Replacement

Tools and Materials Required

  1. Wrench set: For loosening and tightening bolts and nuts.
  2. C-clamps or locking pliers: To hold the garage door in place.
  3. Two sturdy ladders: For you and a helper if needed.
  4. Sturdy wood: To use as winding bars for torsion springs.
  5. New garage door springs: Make sure they match the specifications of your old springs.
  6. Safety goggles and gloves: To protect against debris and spring tension.

Safety Measures

  • Safety goggles and gloves: Always wear these to protect against small flying parts and metal splinters from spring breaks.
  • Clear Area: Ensure the garage area is clean and free of obstacles.
  • Door Weight: Be aware that you will be lifting and securing the full weight of the door.

Initial Checks

  1. Door Position: Ensure the door is closed for both types of springs.
  2. Disconnect the Opener: Always disconnect the garage door opener before starting.
  3. Secure the Door: With C-clamps or locking pliers, ensure the door won't roll down unexpectedly.

A. Steps to Replace Torsion Springs

Step 1: Unplug the Garage Door Opener

Unplugging the garage door opener is crucial to prevent accidental activation, which could result in serious injury.

Step 2: Secure the Door

Place C-clamps or locking pliers on the tracks beneath the lowest door rollers. This ensures the door remains stationary.

Step 3: Wind Down the Old Spring

Use winding bars, not screwdrivers, which are not designed to handle the torsion spring's force. Gradually unwind the spring—one quarter turn at a time. After each quarter turn, pause to relieve tension on the winding bar before proceeding.

Step 4: Remove the Old Spring

Disconnect the springs from the center bracket and slide them off the rod. Keep your head out of the path of the rods and torsion garage door springs to avoid injury.

Step 5: Install the New Spring

Slide the new springs on the rod and secure them into the center bracket. Ensure the springs are properly seated in their end brackets, and the winding cones are facing away from the center bracket.

Step 6: Wind Up the New Spring

Wind the springs as before, but you're winding it up to store energy this time. Tighten the set screws and ensure they are flush with the shaft to prevent them from loosening.

Step 7: Test

After everything is tightened and set, remove the clamps or pliers from the tracks. Apply a garage door lubricant, then open and close the door a few times, checking for any issues.

B. Steps to Replace Extension Springs

Step 1: Open the Door and Secure

Fully open the garage door and secure it in this position with C-clamps on the tracks.

Step 2: Remove the Safety Cable and S-Hook

Be cautious as you unhook the safety cable; the system may still have some residual tension.

Step 3: Remove the Old Spring

Disconnect the old springs from both the track bracket, the cable drum, and the pulley system. Store them away from your working area.

Step 4: Install the New Spring

Attach the new garage door extension springs to the pulley system and track bracket, ensuring they are properly hooked.

Step 5: Reattach Safety Cables

Never forget to reattach safety cables and S-hooks. They are your secondary defense against a spring breaking and causing damage or injury.

Step 6: Test

Remove the C-clamps and slowly lower the garage door. If the door lifts or lowers unevenly, adjustments may be needed.

The Lifespan of Garage Door Springs

All mechanical components have a shelf life, and garage door repair and springs are no exception. Typically, they last about 7-9 years, subject to usage and upkeep. The continuous strain of elevating and descending the door gradually wears the springs, leading them to snap eventually.

The Risks of a Broken Garage Door Spring

A malfunctioning garage door spring can introduce multiple risks:

  • Safety Hazard: A spring breaking during the door's movement can result in the door plummeting, potentially causing harm or damage.
  • Security Issue: An improperly functioning garage door can compromise the safety of your belongings.
  • Inconvenience: Non-operational springs can render garage doors inoperative, obstructing garage access.

Disclaimer: The procedures detailed in this article are for informational purposes only. Attempting to undertake a garage door spring replacement is risky and should only be undertaken by those experienced in handling such repairs. Always exercise extreme caution, consider garage door maintenance tips, and hire a professional for this work. Therefore:

Why Choose Professional Services?

If you suspect your garage door springs are reaching their end or have already snapped, it's vital to consult experts before resulting in serious garage door opener problems. Here's why:

  • Expertise: With extensive experience, professionals comprehend the complexities of garage door springs.
  • Prompt Service: Quick response times ensure your garage door's swift restoration.
  • Quality Workmanship: Leveraging top-tier parts and tools, professionals guarantee lasting repairs, granting you peace of mind.

Frequently Asked Questions on How to Replace Garage Door Springs

a) How do you open a garage door with a broken spring?

If your garage door spring is broken, it's highly recommended to call a professional for repair, as handling garage door springs can be extremely dangerous. However, if you absolutely must open it temporarily, you'll need two people, winding bars, a wrench set, and vise grips.

Disconnect the garage door opener and clamp the vise grips onto the tracks to prevent the door from slamming down. One person uses winding bars to manually wind tension into the remaining good spring while the other lifts the door. Keep in mind this is a temporary measure, and professional repair is essential for long-term safety.

b) How do I know if my garage door springs need replacing?

If your garage door is not operating smoothly, it might be an issue with the springs. Signs that your garage door springs may need a replacement include difficulty lifting the door manually, a door that opens or closes unevenly, loud, creaking noises during operation, or visible gaps in the spring coils.

In some cases, the door may not open or close at all. Worn-out springs can pose safety risks and should be attended to immediately before they become a serious garage door problem. If you notice these symptoms, calling a professional to inspect and help replace garage door springs is advisable, as DIY replacement can be dangerous.


While garage door springs might appear insignificant, their role is indispensable, and replacing them can be challenging and comes with potential risks. You can complete this job with the right preparation and attention to detail. However, If you ever encounter spring-related issues, seek expert services.

They'll guarantee your door's prompt and efficient recovery, protecting your assets and assuring seamless operations for the foreseeable future. Always take all necessary safety precautions and consult the manufacturer's instructions for any specific requirements related to your garage door model.
