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. If your door has completely stopped working because of a broken spring, don’t attempt to force it open manually — read our guide on locked out of your garage in Neenah — here’s the safe way to get back in first.
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.
That uneven stress doesn’t just wear out the springs faster — it puts strain on every other component connected to your door system. Our professional garage door repair team in Northeast Wisconsin sees this kind of chain-reaction damage regularly when homeowners delay a proper two-spring replacement.
Keeping both springs on the same wear cycle ensures your door stays properly balanced, reduces wear on every moving part, and keeps your opener from overworking itself into an early failure.
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 exactly 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. For all spring work, always call Garage Door Squad’s repair professionals serving Appleton and the Fox Cities.
Cost: One Spring vs. Both
Yes, replacing just one spring costs 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 fee, and more downtime — usually at the worst possible moment.
Replacing both springs together is typically more cost-effective, saves you from repeat visits, and restores full reliability to your entire door system. While you’re investing in your door’s longevity, it’s also a good time to consider whether your door itself needs attention — if panels have been stressed by years of imbalanced spring operation, our guide to garage door panel replacement in Appleton can help you assess whether that’s worth addressing at the same time.
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. Replacing both at once gives you smoother operation, protects your opener, prevents safety risks, and saves you from paying for another repair just months later.
And if your springs have been struggling for a while, it may also be worth considering whether this is the right time for a full door upgrade. Many homeowners in Appleton and Neenah use a spring replacement visit as the moment they finally make the switch to a door style they’ve always wanted — options like faux wood garage doors in Neenah offer a beautiful, low-maintenance look that pairs perfectly with a freshly serviced door system.
