Garage Door Springs in Melbourne Beach: Torsion vs. Extension (What's the Difference?)

2026-09-25 5 min read

Most homeowners don't know what type of springs their garage door uses until one fails. The two main kinds are torsion and extension springs, and they work in completely different ways. Understanding which one you have saves you time, money, and confusion when you need a repair or replacement.

How Torsion Springs Work

Torsion springs sit above your garage door opening, mounted horizontally on a shaft. They twist and untwist to lift and lower the door. Think of it like a wound-up rubber band releasing energy.

Here's what makes them special: they counterbalance the weight of your entire door. When you open the door, the spring torques (twists) to reduce the load your opener has to pull. When you close it, the spring stores that energy again. This is why a garage door feels light when you manually push it up.

Torsion springs typically last 7 to 9 years with normal use. That lifespan depends on how many cycles your door goes through. A cycle is one open and one close. If your family opens and closes the door 4 times a day, you're looking at roughly 10,000 to 15,000 cycles per year.

How Extension Springs Work

Extension springs run along the left and right sides of your garage door frame, usually above the horizontal tracks. Instead of twisting, they stretch and contract like traditional springs. When the door goes up, they extend. When it closes, they contract and pull the door down.

You'll typically find two extension springs working together, one on each side. They're less expensive than torsion springs but require more maintenance because they wear unevenly. If one snaps, the other has to carry the entire load, which causes it to fail faster.

Extension springs also last around 7 to 9 years, though some wear out sooner if the door isn't balanced properly.

Key Differences That Matter

Safety first. Torsion springs are safer because they're contained above the door. If one snaps, it stays in place. Extension springs can whip across your garage when they fail, creating a hazard for anyone nearby. This is why DIY replacement is genuinely dangerous with extension springs.

Cost. Torsion springs cost more upfront (usually $200 to $400 per spring, depending on door weight), but extension springs are cheaper initially. However, extension springs often need both replaced at once, which levels out the total cost. Check out our honest breakdown of garage door cost and pricing in Melbourne Beach for a full picture.

Durability. Torsion springs wear more evenly because both sides of the spring experience equal stress. Extension springs on one side often wear faster than the other, throwing your door out of balance.

Opener strain. A garage door opener works harder with extension springs because the springs don't reduce the weight as effectively. This means your opener motor burns out sooner.

Signs Your Springs Need Attention

A snapped spring is obvious: your door either won't open at all, or the opener struggles and strains loudly. You might also notice the door is crooked, sagging on one side, or moving slower than usual.

Don't wait. A broken spring puts pressure on your opener and cables. Continuing to use it can turn a $300 repair into a $1,000 problem. If you're seeing these warning signs, learn what to do right now with a snapped spring or schedule a free estimate to see what you're working with.

When to Call a Professional

Spring replacement isn't a weekend DIY project. The springs are under intense tension, and releasing that tension incorrectly can cause serious injury. A professional can identify which type of spring you have, measure the door weight, test the balance, and install the correct replacement.
