Should Both Garage Door Springs Be Replaced At The Same Time In Troy, MI?

Should Both Garage Door Springs Be Replaced At The Same Time? A 13-Year Garage Door Technician Explains Why the Answer Is Usually Yes

The Question Every Homeowner Asks After a Spring Breaks

After more than 13 years repairing garage doors throughout Troy, Michigan, I've noticed that nearly every broken spring service call eventually leads to the same question.

One spring has snapped. The homeowner sees the visible gap in the torsion spring above the garage door. The door won't open properly, and they understand that the broken spring needs to be replaced.

Then they ask:

"If only one spring is broken, why should I replace both?"

It's a fair question.

At first glance, replacing only the broken spring seems logical. If one spring failed and the other still appears intact, why spend money replacing a part that hasn't broken yet?

While there are situations where replacing a single spring makes sense, I can tell you from years of real-world experience that replacing both springs at the same time is usually the smartest decision for performance, safety, reliability, and long-term value.

This isn't about selling extra parts. It's about understanding how garage door spring systems actually work and what typically happens after one spring reaches the end of its life.

If you're facing a broken garage door spring and wondering whether both springs should be replaced, this article will explain everything you need to know.

Understanding How A Two-Spring System Works

Most double-car garage doors in Troy use a two-spring torsion system.

These springs are mounted above the garage door opening and work together to counterbalance the weight of the door.

Think of them as teammates.

Each spring shares part of the workload every time the garage door opens and closes.

If the door weighs 200 pounds, both springs are contributing to offset that weight.

Every cycle places stress on both springs simultaneously.

Every morning when the door opens, both springs work.

Every evening when it closes, both springs work again.

From the day they are installed, they experience virtually identical usage.

That's a very important detail.

Because while one spring may break first, the second spring has been aging right alongside it.

Garage Door Springs Wear Out Together

One of the biggest misconceptions homeowners have is assuming the unbroken spring is still "good."

Technically, it may not be broken.

That doesn't mean it isn't worn out.

Imagine buying two tires for your vehicle and driving 80,000 miles on them. If one tire blows out, would you consider the other tire brand new simply because it hasn't exploded yet?

Of course not.

The remaining tire has experienced the exact same mileage and wear.

Garage door springs work the same way.

If one spring has reached the end of its lifespan, the second spring is usually very close behind.

The fact that it hasn't broken yet doesn't mean it has years of life remaining.

In many cases, it's simply waiting its turn.

Springs Are Rated By Cycles, Not By Luck

Garage door springs are designed with cycle ratings.

A cycle consists of one complete opening and closing of the garage door.

Most standard residential springs are rated for approximately 10,000 cycles.

Higher-quality springs may be rated for 20,000, 30,000, or even 50,000 cycles.

The important thing to understand is that both springs experience the same number of cycles.

If one spring breaks after 10,000 cycles, the second spring has also completed approximately 10,000 cycles.

It's not operating at half age.

It's operating at essentially the same age.

That's why I often tell homeowners that a broken spring isn't really an isolated failure. It's usually a sign that the spring system has reached the end of its expected lifespan.

What Happens If You Replace Only One Spring?

Let's say you decide to replace only the broken spring.

The garage door is repaired.

Everything seems fine.

The door opens and closes again.

Then three weeks later the second spring breaks.

I've seen this happen hundreds of times.

Sometimes it's three months later.

Sometimes it's two weeks later.

Sometimes it's the very next day.

Now the homeowner pays for another service visit, another labor charge, and experiences another garage door breakdown.

What initially appeared to save money often ends up costing more.

The frustrating part is that the second failure was completely predictable.

The remaining spring wasn't new.

It was simply worn out but not yet broken.

The Balance Problem Most Homeowners Never Consider

Another issue involves balance.

Garage doors operate best when both springs provide equal lifting force.

When a brand-new spring is paired with an old, worn spring, the system becomes less balanced.

The new spring is stronger.

The old spring has weakened from years of use.

That imbalance can affect how smoothly the door operates.

The opener may work harder.

The door may not travel as consistently.

Additional strain can be placed on cables, drums, bearings, and other hardware.

A matched set of springs creates a properly balanced system.

That's one of the reasons professional technicians frequently recommend replacing both springs together.

Why Your Garage Door Opener Will Thank You

One of the most expensive mistakes homeowners make is overlooking the impact spring problems have on the opener.

The opener is designed to move a balanced door.

It is not designed to lift a heavy, unbalanced door.

When springs weaken, the opener works harder.

When one spring breaks, the opener works much harder.

When spring balance becomes inconsistent, the opener continues compensating.

Over time, this extra workload can shorten the lifespan of the opener.

I've replaced countless motors, gears, sprockets, and drive systems that suffered because the spring system wasn't functioning properly.

A balanced pair of springs helps protect one of the most expensive components of the entire garage door system.

The Cost Difference Is Usually Smaller Than You Think

Many homeowners initially focus on the price difference between replacing one spring and replacing two.

That reaction is understandable.

However, it's important to look at the total picture.

The largest portion of most spring replacement jobs isn't the spring itself.

It's the service visit, labor, vehicle expenses, insurance, expertise, and time involved in completing the repair safely.

When replacing both springs during the same visit, you're often paying for labor only once.

If the second spring breaks later, you're paying for another service call, another labor charge, and another appointment.

Over the long run, replacing both springs is frequently the more economical choice.

When Replacing Only One Spring Might Make Sense

While I generally recommend replacing both springs, there are exceptions.

For example, if the second spring was recently replaced due to a previous repair, replacing only the newly broken spring may be perfectly reasonable.

Similarly, if the springs are significantly different in age because of prior work, replacing a single spring can sometimes make sense.

There are also situations involving custom systems where the spring configuration requires a different approach.

The key is evaluating the actual condition and age of the remaining spring rather than simply assuming it still has substantial life remaining.

An experienced technician can usually determine whether replacing one spring or both is the smarter option.

How Long After One Spring Breaks Will The Other One Fail?

This is one of the questions homeowners ask most frequently.

The honest answer is that nobody knows.

The second spring could break tomorrow.

It could last another six months.

It could survive another year.

What I can say with confidence is that once one spring has failed due to normal wear, the second spring is operating on borrowed time.

After thousands of spring replacement jobs, I've seen enough patterns to know that the remaining spring usually doesn't have nearly as much life left as homeowners hope.

That's why I view the first broken spring as a warning sign for the entire system.

Why Professional Technicians Recommend Replacing Both

Some homeowners assume technicians recommend replacing both springs simply to increase the size of the repair.

The reality is much simpler.

We've seen what happens when only one spring gets replaced.

We've seen the callback a few weeks later.

We've seen the second failure.

We've seen the frustration.

We've seen the additional expense.

Most experienced garage door technicians make recommendations based on patterns they've observed thousands of times.

After performing spring replacements for more than a decade, I can tell you that replacing both springs usually results in fewer breakdowns, better door balance, improved reliability, and happier homeowners.

The Safety Factor

Garage door springs aren't just mechanical components.

They're safety components.

A properly balanced garage door is safer to operate.

It places less stress on the opener.

It reduces strain on the cables and hardware.

It helps the door move predictably and consistently.

When springs are mismatched in age and strength, system performance becomes less predictable.

Anything that affects balance can potentially affect safety.

That's another reason I prefer installing matched spring pairs whenever possible.

What About High-Cycle Springs?

Whenever I'm replacing springs, I often discuss high-cycle options with homeowners.

Most builder-grade springs are rated around 10,000 cycles.

Higher-cycle springs offer significantly longer service life.

For families that use the garage as their primary entrance, upgrading can be an excellent investment.

A 30,000-cycle spring may last roughly three times longer than a standard 10,000-cycle spring under similar conditions.

If you're already replacing springs, it can be a great opportunity to improve the longevity of the entire system.

The Real-World Example I See Every Week

Let's imagine two identical springs were installed on a garage door eight years ago.

The family uses the garage multiple times every day.

One spring finally breaks.

The second spring has completed the exact same number of cycles.

Would you expect it to last another eight years?

Probably not.

That's the reality homeowners are facing when deciding whether to replace one spring or both.

The second spring isn't starting at zero.

It's already near the finish line.

The question isn't whether it will fail.

The question is when.

Final Thoughts From A Troy MI Garage Door Technician

After more than 13 years repairing garage doors throughout Troy and the surrounding communities, my recommendation is usually straightforward.

If your garage door uses two springs and one breaks due to normal wear, replace both.

The springs have worked together since the day they were installed. They've experienced the same number of cycles, the same weather conditions, and the same daily usage. If one has reached the end of its lifespan, the other is usually close behind.

Replacing both springs provides better balance, protects the opener, improves reliability, reduces the likelihood of another breakdown, and often saves money in the long run.

While there are exceptions, the vast majority of homeowners benefit from treating the spring system as a pair rather than focusing solely on the single spring that happened to break first.

At Troy MI Garage Door Service, I've seen firsthand how much frustration can be avoided by replacing both springs during the initial repair. It's one of those situations where spending a little more today often prevents spending much more tomorrow.

When one spring breaks, don't just think about the broken spring. Think about the spring that's been doing the exact same work right beside it for years. Chances are, it's much closer to failure than it appears.
