Working on a garage door can feel intimidating—especially when springs are involved. If you’re trying to figure out how to release tension on a garage door spring, you’re not alone. This guide will walk you through the process safely and clearly, helping you avoid costly mistakes or serious injuries.

What Does Garage Door Spring Tension Mean?

Garage door springs store mechanical energy that helps lift and lower the heavy door. When we talk about “tension,” we’re referring to the force stored in the spring.

There are two main types:

• Torsion springs (mounted above the door)
• Extension springs (mounted along the sides)

Why Would You Need to Release Spring Tension?

Releasing tension is often required before performing repairs or replacements.

Common reasons:

• Replacing a worn-out or broken spring
• Adjusting door balance
• Fixing uneven movement
• Performing general maintenance

📊 Industry insight: Most garage door springs last about 7–10 years or roughly 10,000 cycles, depending on usage.

Is It Safe to Release Garage Door Spring Tension Yourself?

Let’s be clear: this is one of the most dangerous DIY tasks in home maintenance.

Risks include:

• Sudden spring release causing injury
• Tools slipping under pressure
• Door سقوط (falling unexpectedly)

You can DIY if:

• You use the correct tools
• You follow safety steps exactly
• You understand your spring type

Call a professional if:

• You’re unsure about the process
• The spring is damaged or broken
• You lack proper tools

Tools You’ll Need

Before starting, prepare everything:

• Winding bars (essential for torsion springs)
• Adjustable wrench
• Locking pliers (vise grips)
• Safety gloves and goggles
• Stable ladder

⚠️ Never substitute winding bars with screwdrivers.

How To Release Tension On A Torsion Spring (Step-by-Step)

This is the most common and sensitive method.

Step 1: Disconnect Power and Close the Door

• Unplug the garage door opener
• Ensure the door is fully closed

👉 This prevents unexpected movement.

Step 2: Secure the Door

• Clamp locking pliers onto the track
• Place them just below the bottom roller

👉 This keeps the door from lifting during adjustment.

Step 3: Insert the Winding Bar

• Insert the winding bar into the winding cone
• Ensure it is fully seated

👉 You must maintain a firm grip at all times.

Step 4: Loosen the Set Screws

• Use a wrench to loosen screws slowly
• Expect a slight release of tension

⚠️ Keep your body to the side—not directly in front.

Step 5: Unwind the Spring Slowly

• Lower the winding bar carefully
• Insert the second bar into the next hole
• Continue unwinding in ¼-turn increments

👉 Typical guideline:

• 7-ft door → ~30 quarter turns to fully release
• 8-ft door → ~34 quarter turns

Step 6: Repeat for the Second Spring

If your system has two springs:

• Repeat the same process evenly
• Maintain balance to avoid door misalignment

How To Release Tension On Extension Springs

This type is simpler but still requires caution.

Steps:

1. Open the garage door fully
2. Clamp it securely in place
3. Locate the spring hook
4. Carefully disconnect or move it to reduce tension

👉 Always stand clear of the spring’s path.
