Do You Need To Replace Both Garage Door Springs at The Same Time?

It’s Monday morning in Appleton. You’re running late, the kids are in the car, and you push the opener. Instead of lifting smoothly, the garage door jerks, makes a loud bang, and refuses to budge. A technician arrives, takes a quick look, and says: “One of your springs broke. We recommend replacing both.”

Your first thought might be: “Wait… only one spring is broken. Why replace the other?” It’s a fair question, and it’s one we hear often from homeowners across Neenah, Oshkosh, and Northeast Wisconsin.

The honest answer is simple: garage door springs work as a pair, and for balance, safety, and cost-effectiveness, it almost always makes sense to replace both at the same time.

Springs Always Work as a Team

Most modern garage doors are designed with two springs, either mounted on each side of the door or wound together on a torsion bar. They share the weight equally. That means when one breaks, the other has already handled the exact same number of cycles. Even if it hasn’t snapped yet, it’s usually close to the end of its life span.

Why Balance Matters

A garage door with mismatched springs—one new, one worn, won’t operate smoothly. This imbalance can:

• Put extra stress on the garage door opener.

• Cause the door to tilt, bind, or jerk as it moves.

• Lead to uneven wear on cables, rollers, and tracks.

• Increase the risk of another sudden breakdown.

Keeping both springs on the same cycle ensures your door remains properly balanced, which reduces wear and keeps your opener from overworking.

The Safety Factor

Garage door springs are under extreme tension, sometimes holding hundreds of pounds of force. A door supported by only one functional spring is unstable. If the weaker spring suddenly snaps, the door can slam shut or jam halfway. That poses a real risk to people, pets, and vehicles.

This is also why spring replacement is not a safe DIY project. We strongly advise against attempting to handle torsion or extension springs on your own. Even experienced technicians use specialized tools and safety procedures when replacing springs, because a single slip can cause severe injury or major damage to the door system.

Cost: One Spring vs. Both

Yes, replacing just one spring will cost a little less upfront. But here’s the reality: the second spring almost always fails within weeks or months. That means you’ll end up paying for another service call, another installation, and additional downtime. Replacing both springs together is typically more cost-effective, saves you from repeat visits, and restores full reliability.

When Replacing One Might Be Okay

Some older garage doors are built with only a single spring. In that case, you obviously replace the one. But with two-spring systems — which are standard in most modern homes in Northeast Wisconsin, replacing both is the smarter, safer choice.

Think about your daily use:

• Leaving for work in the morning and returning at night.

• Kids opening the door for school and activities.

• Deliveries and quick errands.

Even at just 4–6 cycles per day, that’s over 1,500 cycles a year. Both springs handle the same workload every single time, so if one has broken, the other is almost certainly worn down too.

Frequently Asked Questions

1. How long do garage door springs last?
Standard springs typically last 3–7 years or around 10,000 cycles. Heavy use shortens that lifespan, while high-cycle springs can extend it to 15–20 years.

2. Can I replace just one spring to save money?
You can, but it’s not recommended. The second spring will almost certainly fail soon, leading to another service call. Replacing both together is more reliable and cost-effective.

3. Will replacing both springs make my door safer?
Yes. Balanced springs keep your door stable, protect your opener, and prevent sudden, uneven door movement that could be dangerous.

4. How do I know if both springs are worn?
If one has snapped, the other has already been through the same number of cycles and is near failure. Technicians in Appleton and Neenah can test door balance during a tune-up to confirm.

5. Can I replace springs myself?
We do not recommend it. Springs are wound under extreme tension and can cause serious injury if handled incorrectly. Professional replacement is always the safest option.

The Smart, Safe Move for Northeast Wisconsin Homes

Every time your garage door opens and closes, both springs carry the load. When one breaks, the other is already near the end of its lifespan.
