Garage door extension springs are essential for ensuring the smooth and balanced operation of your garage door. They counteract the door’s weight, making opening and closing effortless. However, like all mechanical components, they wear out over time. Proper maintenance can significantly extend their lifespan, saving you money on repairs and replacements.

In this guide, we’ll cover essential maintenance tips to keep your garage door extension springs in top condition while enhancing safety and performance.

Why Garage Door Extension Springs Need Regular Maintenance

Extension springs are under constant tension, stretching and contracting every time you operate the garage door. Over time, this stress can lead to:

• Metal fatigue – Springs lose elasticity and may snap.
• Rust and corrosion – Exposure to moisture and temperature changes weakens the metal.
• Misalignment – Improper tension can cause uneven wear.

Regular maintenance helps prevent sudden failures, which can be dangerous and costly.

6 Essential Maintenance Tips for Garage Door Extension Springs

1. Inspect Springs Monthly for Wear and Damage

Regular visual inspections help catch early signs of wear. Look for:

• Cracks or gaps in the coils
• Rust or corrosion
• Loose or damaged hooks and cables

If you notice any of these issues, consider replacing the springs before they fail.

2. Lubricate the Springs Every 3-6 Months

Lubrication reduces friction and prevents rust. Use a silicone-based or lithium-based garage door lubricant (avoid WD-40 as it attracts dust).

• Apply lubricant along the length of the spring.
• Remove excess to prevent dirt accumulation.

3. Check and Adjust Spring Tension

Improper tension can strain the springs and opener.

• Check balance: Disconnect the opener and manually lift the door to halfway position. If it doesn’t stay in place, the springs may need adjustment.
• Consult a professional if adjustments are needed—working with high-tension springs can be dangerous.

4. Keep the Springs Clean

Dirt and debris accelerate wear.

• Wipe down springs with a dry cloth.
• Remove cobwebs and grime that can cause abrasion.

5. Replace Worn-Out Safety Cables

Safety cables run through extension springs to prevent them from flying off if they break.

• Ensure cables are intact and securely fastened.
• Replace frayed or rusted cables immediately.

6. Schedule Professional Inspections Annually

A garage door technician can:

• Detect hidden wear.
• Ensure proper alignment and tension.
• Recommend replacements before a failure occurs.

When to Replace Garage Door Extension Springs

Even with proper maintenance, extension springs typically last 5-10 years, depending on usage. Signs you need a replacement include:

• Visible gaps or stretched coils
• Loud snapping or popping noises
• Difficulty in smooth opening or closing of the door

Replacing both springs at the same time ensures balanced operation.

Safety Precautions When Handling Extension Springs

• Never attempt to repair or adjust springs under tension—this can cause serious injury.
• Use safety goggles and gloves when inspecting or lubricating.
