I still remember the sound.
It was a crisp, early spring morning in Green Bay, and I was sipping my first coffee when my phone buzzed. A homeowner on the east side called in a panic — she said, “My garage door just slammed shut like a thunderclap. I think something exploded.”
When I arrived, the culprit was exactly what I suspected: a broken torsion spring. The coil had snapped clean in half. But what caught my attention wasn’t the damage — it was what she almost did next. She had watched a video online and was minutes away from trying to replace the spring herself.
If she had — and if her wrench slipped or the tension let go — she could have been seriously injured.
That day reminded me why I always tell customers: garage door springs are small components that carry massive responsibility and risk.
In this post, I want to pull back the curtain on what really goes into spring replacement — the dos, the don’ts, and the hidden details most people (and even some “handymen”) overlook. My goal isn’t just to warn you; it’s to help you understand how to make smart, safe, and long-lasting repair decisions for your home.
Understanding the Real Job Your Garage Door Springs Do
Every homeowner knows their garage door goes up and down. Few realize the door doesn’t actually do the heavy lifting — the springs do.
In a typical Green Bay home, a double garage door can weigh anywhere from 130 to 250 pounds. Your opener isn’t meant to pull that load — the springs act as counterbalance systems that store and release energy with every cycle.
When a spring breaks, that balance disappears. The door becomes dangerously heavy, the opener strains, and the cables can jump the drum.
That’s why spring failure isn’t just inconvenient — it’s a serious mechanical imbalance that affects every part of your garage door system.
Two Types of Springs — and Why It Matters
You’ll find two main types:
- Torsion Springs: Mounted above the door, wound tightly to create torque.
- Extension Springs: Positioned along the tracks, stretching as the door moves.
In Green Bay, where cold winters and humidity fluctuate heavily, torsion springs tend to be more reliable because they maintain better tension control and don’t stretch or rebound as dramatically as extension systems. But here’s the twist — both can wear out faster if the wrong wire gauge or cycle rating was installed to begin with.
Pro Tip:
If your spring lasted less than 5 years, it wasn’t matched properly to your door’s weight or usage pattern.
A properly sized torsion spring should last about 10,000 cycles, or roughly 7–10 years for an average household.
The “DOs” of Garage Door Spring Replacement
Replacing a garage door spring isn’t about swapping a part — it’s about restoring perfect mechanical balance. Here’s what I always tell customers and even my newer technicians to do every single time.
DO #1: Identify the Root Cause Before Installing a New Spring
I’ve seen many repairs fail within months because someone simply “replaced what broke.”
But a spring rarely fails in isolation. It’s often a symptom of:
- Door misalignment
- Deteriorated bearings
- Cables fraying unevenly
- Corrosion from road salt or humidity
Before installing a new spring, inspect every moving component connected to it. Otherwise, you’re just treating the symptom, not the problem.
DO #2: Use the Correct Spring Type and Size
Every door is engineered to specific weight tolerances. Installing a “close enough” spring — even one that looks right — can throw off the balance.
I once arrived after a handyman installed a spring that was two wire sizes off. The door opened beautifully halfway, then reversed every time. The opener’s sensors weren’t the problem; the torque was.
Pro-level tip: Always match the spring to your door’s weight, height, drum size, and track radius. That’s how we at WI Garage Door LLC guarantee smooth operation from the first lift.
DO #3: Lubricate the Springs Regularly
This one’s so simple, yet I’d estimate 80% of homeowners skip it.
A light coat of garage door lubricant (not WD-40) reduces friction, prevents rust, and extends spring life significantly — especially through Green Bay’s winter freeze cycles.
Do it twice a year:
- Once before winter (to repel moisture)
- Once in spring (to refresh the coating)
The “DON’Ts” — Mistakes That Cost Homeowners the Most
For every “do,” there’s a “don’t” that can lead to expensive or dangerous outcomes.
Here are the ones that matter most.
DON’T #1: Try to Unwind or Rewind Springs Without Training
This is the big one.
A wound torsion spring can hold enough torque to launch a wrench through drywall — or worse. Every year, emergency rooms across Wisconsin treat injuries caused by DIY garage door repair attempts.
Even with professional winding bars, you need to know exactly how many quarter turns your specific spring set requires. One turn too many or too few can stress your opener or make the door uncontrollable.
So my honest advice?
If you’re standing on a ladder holding a bar, watching a YouTube video, and sweating — stop right there. Call a professional. It’s not worth the risk.
DON’T #2: Ignore Signs of Imbalance or Noise
A garage door rarely “just breaks.” It whispers first — squeaks, jerks, or slams slightly out of rhythm.
If your door:
- Opens unevenly
- Makes grinding or popping noises
- Feels heavier than usual
…that’s your warning. The spring might be weakening, and catching it early can prevent a complete failure.
I tell my clients in Green Bay all the time — if it sounds different, it’s talking to you.
The Counterintuitive Truth: Why “New” Doesn’t Always Mean “Fixed”
Here’s something that surprises even experienced homeowners:
Sometimes a new spring won’t solve your problem — even if it’s installed perfectly.
How can that be?
Because springs age together as a set. Replacing only one when both have gone through the same cycle count leads to uneven torque. The result? The new spring carries more tension, forcing the weaker one to fail sooner — like putting a new tire next to a bald one.
At WI Garage Door LLC, we always replace springs in pairs, not for profit, but for precision. The system functions as a unit — and the balance of torque is everything.
Preventive Care: The Secret to Springs That Last Twice as Long
If there’s one truth I’ve learned after years of servicing garage doors across Green Bay, it’s this:
Most spring failures are preventable.
I’m not exaggerating.
In fact, I’ve been called out to homes where a simple 10-minute maintenance check — done once or twice a year — could’ve saved the homeowner from a complete spring snap.
Lubricate and Listen
As I mentioned earlier, lubrication is your spring’s best friend. But here’s the part most people overlook: sound is your early-warning system.
Once every couple of months, disconnect the opener and lift the door manually.
Listen.
If you hear scraping, grinding, or a chirp on the way up or down, your spring tension might be off-balance — or corrosion could be creeping in.
A quiet door is a healthy door.
Test the Balance
Here’s a quick pro trick anyone can do safely:
- Disconnect the opener.
- Manually lift the door halfway and let go (carefully).
If it stays put, your spring tension is correct.
If it drops or rises, the balance is off — and that means one or both springs are beginning to lose their strength.
Why Green Bay’s Climate Is Especially Tough on Garage Door Springs
When I first started WI Garage Door LLC, I underestimated just how much Wisconsin weather affects garage systems.
Between winter salt, below-zero mornings, and humid summers, your springs go through more stress cycles than almost anywhere else in the Midwest.
Cold Weather = Brittle Metal
In freezing temps, steel loses elasticity. Springs wound under tension can fracture suddenly when cold metal contracts.
That’s why, every winter, we see a surge in emergency spring calls across Brown County.
A small step like keeping your garage above freezing — even slightly — can make a difference.
Humidity = Hidden Rust
Green Bay’s lake humidity is tough on bare steel. If your garage isn’t well-ventilated, that moisture settles on the springs.
Rust eats away at the coils, creating weak points that can snap under load.
That’s why we always apply a protective, silicone-based coating during every spring replacement. It’s not a gimmick — it’s the difference between a spring that lasts 3 years and one that lasts 10.
Common Myths About Garage Door Spring Replacement
Let’s clear the air on a few misconceptions I hear all the time from homeowners — and even from some technicians.
Myth #1: “If one spring breaks, the other one’s fine.”
False.
As I mentioned earlier, springs work in pairs and age in pairs. Replacing only one means you’re just resetting the countdown until the next failure.
Myth #2: “It’s just a metal coil — they’re all the same.”
Nope.
Every spring has a specific wire gauge, length, and coil count matched precisely to your door’s weight.
Installing the wrong one might lift your door today, but it’ll cause premature wear on your opener and hardware.
Myth #3: “I can just measure the old spring and order one online.”
This is one of the most common traps.
By the time a spring breaks, it’s stretched and deformed. Those measurements are no longer accurate.
I’ve seen homeowners spend hours ordering parts online, only to end up calling us after the second wrong delivery.
What Really Sets a Professional Garage Door Company Apart
When I walk into a customer’s garage, I’m not just fixing a spring — I’m protecting their safety and convenience.
A true professional doesn’t rush the job; they diagnose the system as a whole.
At WI Garage Door LLC, our technicians in Green Bay always follow a complete inspection checklist:
- Door balance and alignment
- Cable and drum condition
- Bearing plates and end bearings
- Spring cycle rating match
- Opener force calibration
Because in my experience, a proper repair is one you never have to think about again.
The Mentor’s Note: What I’d Tell Every Green Bay Homeowner
Let me level with you.
I’ve been in this trade long enough to see every kind of fix — from DIY patch jobs to quick contractor swaps — and I can tell when a spring replacement was done with precision versus guesswork.
Here’s the counterintuitive insight that separates a professional job from a quick fix:
A garage door spring replacement isn’t about strength — it’s about balance.
You can have the toughest steel in the world, but if the torque, cable tension, or drum alignment is even slightly off, that door will fail early.
It’s not the spring that breaks first — it’s the harmony between all its components that collapses.
That’s why every time I finish a job, I do one final test:
I open the door slowly by hand, then close it and listen.
If it glides silently — that’s when I know it’s not just fixed… it’s right.
