I’ve come to realize that the springs are the true powerhouses of the system. Let me walk you through everything you need to know to choose the right one.
Garage Door Springs
Garage door springs come in two main types: torsion springs and extension springs. They do the same job but in very different ways.
Torsion Springs
Torsion springs are mounted horizontally above your garage door. They work by twisting to store energy when the door is closed and unwinding to lift it. These springs are durable, smooth, and reliable. However, they require precision during installation to avoid issues.
Extension Springs
Extension springs run along the sides of the garage door tracks. They stretch and contract to balance the door’s weight. While they’re often less expensive and easier to replace, they don’t have the same longevity or smoothness as torsion springs.
How to Choose the Right Garage Door Spring
Picking the right spring isn’t rocket science, but it’s not guesswork either. Follow these steps:
Step 1: Know What You’re Working With
Identify your spring type:
- Torsion springs: Look above the garage door for springs mounted horizontally on a metal shaft.
- Extension springs: Look along the sides of the tracks for long, stretching springs.
Step 2: Take Measurements
You’ll need precise measurements:
- For Torsion Springs:
- Wire Size: Count 10 or 20 coils, measure the length, and use a spring wire gauge chart.
- Inside Diameter: Check for size stamped on the spring’s winding cone or measure directly.
- Overall Length: Measure the spring from end to end in a relaxed state.
- For Extension Springs:
- Relaxed Length: Measure the spring end-to-end without tension.
- Weight Capacity: Match color-coded springs to your door’s weight using a chart.
Step 3: Weigh Your Door
Disconnect the opener, lower the door manually, and place a bathroom scale under the center of the door to get the weight.
Step 4: Consider Durability
Look for high-cycle springs for longevity. Standard springs last ~10,000 cycles, but high-cycle springs can last up to 25,000.
Common Mistakes (And How to Avoid Them)
- Choosing the Wrong Spring: Guessing the size or type can cause serious problems. Always measure carefully.
- Ignoring Safety: Springs are under immense tension. Mishandling them can be dangerous—call a professional if unsure.
- Forgetting About Balance: An unbalanced door strains the opener and leads to premature wear. Adjust it properly.
Pro Tips From the Trenches
- Always Lubricate: Apply lubricant to reduce noise, prevent rust, and extend spring life.
- Inspect Cables and Rollers: Check for wear and tear on other components while working on your springs.
- Test the Door: After replacing springs, disconnect the opener and manually lift the door. It should move smoothly and stay balanced.
Safety First, Always
Garage door springs are not forgiving. They’re under a tremendous amount of tension, and mishandling them can result in serious injuries. If you’re not confident in your DIY skills, hire a professional—it’s worth the peace of mind.
