That bang from the garage at 6 AM? Yeah, that was your spring.
If you've never heard a torsion spring break, it sounds like a gunshot. People call 911 over it. I've had customers tell me they thought someone hit their house with a car, or that a shelf collapsed, or that a pipe burst. Nope. It was a coil of steel about eighteen inches long releasing every ounce of stored energy it had — all at once, in a fraction of a second. And now your garage door won't move. Your car is trapped. You're standing there in your bathrobe at six in the morning in January, it's fourteen degrees outside in Bend, and you're wondering what just happened and who to call.
I'm Tyler Ottesen. I own Brokentop Garage Doors, and I've been replacing springs across Central Oregon since 2016. In ten years I've replaced maybe 2,000 springs. I've never had one I installed fail within warranty. That's because we use the right springs for the right door — every single time, no shortcuts, no guessing. Springs are the most important mechanical component in your garage door system and the number one failure point. They're also, frankly, the most dangerous part of the entire setup. This is the topic I take most seriously in this business, and I'm going to walk you through everything you need to know — as a homeowner in Central Oregon — about why springs break, what to do when they do, what it costs, and why you should never, ever try to handle this yourself.
The Spring Is Doing All the Work — and It's More Dangerous Than You Think
Most people think the garage door opener lifts the door. It doesn't. The opener is a little motor that nudges things along, provides the push to get the door moving. The spring is what actually counterbalances the full weight of your garage door. We're talking 150 to 400 pounds, depending on the door — the size, the material, whether it's insulated, whether it has windows. All of that weight is held up by tightly wound steel. When the spring is healthy, you should be able to disconnect the opener, grab the door handle, and lift it with one hand. Maybe fifteen or twenty pounds of effort. That's because the spring is carrying the rest.
When a spring breaks, that counterbalance vanishes. Instantly. The door becomes dead weight. If it was closed when the spring snapped, the opener will try to lift it, strain against 200 or 300 pounds it was never designed to move, and either stall out or shut itself off. If the door was open when the spring broke — and this is the scenario that scares me — it can come crashing down. A 250-pound slab of steel and wood dropping in an uncontrolled free fall. If someone's standing in the doorway, if a kid is riding their bike underneath it, if you're walking through carrying groceries — that's a trip to the emergency room. Or worse.
I don't say that to be dramatic. I say it because I've seen the aftermath. Bent tracks where a door slammed down. Cracked concrete from the impact. A car hood with a crease across it from a door that dropped while someone was pulling in. Springs failing is not a minor inconvenience. It's a mechanical failure of something holding hundreds of pounds over your head, and it deserves to be treated that way.
Which brings me to the two types of springs you'll find on residential doors, and which one is on your garage affects everything — how long the springs last, how safe they are when they fail, and what happens during replacement.
Torsion springs are mounted on a steel shaft above the garage door opening. They work by twisting — storing energy as torque when the door closes and releasing it when the door opens. Look above your garage door. If you see one or two tightly wound coils sitting on a horizontal bar, those are torsion springs. The critical safety advantage of torsion springs is containment. When a torsion spring breaks, it stays on the shaft. It doesn't go anywhere. You'll hear the bang, the door won't work, but the broken spring remains up there above the door where it's not going to hit anyone. That's by design.
Extension springs are different, and they worry me more. They're mounted along the sides of the door, running parallel to the horizontal tracks. They work by stretching — extending when the door closes and contracting to pull the door up when it opens. Extension springs were standard on most garage doors built before 2000 or so, and plenty of them are still out there. The problem is what happens when one breaks. An extension spring under tension that snaps can become a projectile. I've seen them embedded in drywall. I've seen them wrapped around car mirrors. I've seen them leave dents in toolboxes across the garage. A safety cable running through the center of each extension spring is supposed to prevent this, but on older installations those cables are often missing or deteriorated. If you have extension springs without safety cables — and you might not even know — that's a hazard sitting in your garage right now.
Every installation we do uses torsion springs. If your door currently runs on extension springs, I'd encourage you to convert to torsion next time replacement comes around. It requires adding a torsion shaft and hardware above the door, which adds some cost, but the improvement in safety, longevity, and smooth operation is substantial. We can usually do the conversion in a single visit.
Why Springs Die Faster in Central Oregon
Spring life is measured in cycles, not years. One cycle is a single open-and-close of the door. The cheapest springs — the ones most companies install by default — are rated for 10,000 cycles. At four cycles per day, which is average for most households, that works out to about seven years in laboratory conditions. Perfect temperature, no corrosion, no dust, no stress beyond the designed load.
Central Oregon doesn't offer laboratory conditions. Not even close.
Our temperature swings are brutal on metal. Bend drops below freezing roughly 200 nights a year. Steel gets brittle in the cold. Every cycle at fifteen degrees puts more stress on a spring than the same cycle at sixty degrees, because the molecular structure of the metal is less flexible. Micro-fractures develop faster. But it's not just the cold — it's the swing. We regularly get thirty to forty degree temperature differentials between overnight lows and afternoon highs from October through April. The metal expands and contracts over and over, day after day, month after month. That thermal cycling accelerates fatigue at exactly the stress points where the spring coils flex most.
Then there's our high-desert environment. Bend gets about twelve inches of rain per year. That dry air pulls moisture out of lubricants fast. Within a year or two, spring coils that haven't been re-lubricated are running nearly dry, and friction between the coils chews through metal on every cycle. Add in the fine volcanic dust that Central Oregon's soil produces — the pumice grit that settles on everything — and you've got a mild abrasive working its way into the coils alongside dried-out lubricant. It's not one thing that kills springs early up here. It's all of it, compounding.
The practical result: expect two to three years less life than the manufacturer's rating. A 10,000-cycle spring that might last seven years in Portland or the Willamette Valley may only make it four or five in Bend. This is exactly why we install 20,000-cycle galvanized springs as our standard — not as an upsell, not as a premium option, but as the baseline. The galvanization resists the corrosion our freeze-thaw cycles cause on bare steel. Non-galvanized springs develop visible surface rust within two or three years up here, and rust accelerates metal fatigue dramatically. Our 20,000-cycle galvanized springs typically last ten to twelve years in Central Oregon. That's the kind of longevity you should expect from a proper spring job.
Usage patterns matter too, and people tend to underestimate theirs. Four cycles a day is the national average, but think about your household. Two cars, two drivers — that's already eight cycles. Teenagers coming and going? More. Using the garage as your primary entry point, which is common around here because nobody wants to track snow and mud through the front door? You might hit ten cycles a day without thinking about it. At that rate, even a 20,000-cycle spring only lasts about five and a half years. Knowing your actual usage gives you a realistic timeline for when replacement is coming.
If your door has two torsion springs and one breaks, the other one has the same age, the same number of cycles, the same wear, and the same exposure to everything I just described. It's living on borrowed time. I've had customers call to schedule a replacement for one spring, and while we're booking the appointment, the second one snaps. Replacing just the broken spring saves you maybe a hundred bucks today and virtually guarantees a second service call within a few months when the other one goes. That second call costs more than if you'd just done both the first time. It's not an upsell. It's the only approach that makes sense mechanically and financially, and any honest tech in this industry will tell you the same thing.
Do Not Touch These Springs Yourself
I need to be blunt about this, and I'm not going to soften it.
A wound torsion spring on a standard two-car garage door holds over 200 pounds of tension. That energy is stored in the coils and managed by winding cones at each end. Professional technicians use hardened steel winding bars — purpose-built tools specifically designed for this job — to carefully release and apply that tension. If a winding bar slips out of the winding cone under load, it becomes a spinning steel projectile powered by 200 pounds of force. If a set screw strips while the spring is under tension, the cone releases and the spring unwinds violently. People have lost fingers. People have taken winding bars to the face. People have died.
I'm not exaggerating. The Consumer Product Safety Commission tracks garage door injuries, and spring-related incidents are among the most severe they document. Broken hands, facial lacerations, fractured skulls, crushed fingers. These aren't freak accidents. They're the predictable result of an untrained person working with an extremely high-tension mechanical system using the wrong tools. A socket extension is not a winding bar. A piece of rebar is not a winding bar. A screwdriver is absolutely not a winding bar. I've seen people try all three. I've seen the results.
And even if you manage to get through the installation without getting hurt, an incorrectly wound spring creates a dangerous door. Too many turns and the door flies open aggressively — it can jump the tracks, which is its own disaster. Too few turns and the door won't stay open, drops unexpectedly, or forces the opener to work far harder than it should. An improperly balanced door puts uneven stress on tracks, cables, rollers, and hinges, creating secondary failures that end up costing more to fix than the spring replacement would have.
Then there's the sizing problem. Torsion springs have to match your door's weight, height, and track configuration precisely. There are hundreds of possible spring specifications, defined by wire diameter, inside coil diameter, and overall length. Install the wrong spring and the door is either too light — which is dangerous — or too heavy, which burns out the opener and wears everything prematurely. Our technicians calculate the correct spring spec on-site using the door's actual weight. Getting this wrong isn't a minor issue. It's a cascading failure that damages other components over time.
I watch the YouTube videos people reference when they tell me they were thinking about doing it themselves. The guy in the video makes it look easy. He doesn't mention that he's done it a thousand times. He doesn't show you the near-misses. He doesn't tell you what happens when the winding cone on your specific door is corroded and the set screw won't seat properly, which happens constantly on older doors in Central Oregon because of our climate. He doesn't tell you what to do when the bearing plate is seized and the shaft won't turn freely, which I run into on maybe one in five jobs. The video shows the ideal scenario. Your garage probably isn't the ideal scenario.
Professional spring replacement runs $300 to $500 for a pair, including everything. Compare that to an ER visit — $2,000 to $5,000 with insurance copays and deductibles. Compare it to a damaged car from a door that wasn't balanced correctly — a thousand dollars or more in body work. Compare it to a destroyed opener from wrong spring tension — $400 to $700 to replace. The professional installation is, genuinely, one of the best deals in home repair. You're paying for someone who has the right tools, the right springs, the right training, and the right experience to do it safely and correctly. Take the deal.
What It Costs and What You Get
You're looking at $300 to $500 for a pair of torsion springs, and that includes everything — the springs themselves, all labor, removal and disposal of the old springs, full door rebalancing, opener force adjustment, safety testing, and lubrication of the entire spring assembly. That's our price range for residential doors in the Bend area, and it's representative of fair market pricing for quality work in Central Oregon. Single spring replacement runs $200 to $400, but as I've explained, we replace both. Extension spring pairs run $200 to $350, though if you're replacing extensions I'm going to recommend converting to torsion while we're there.
The springs we install are 20,000-cycle galvanized — not the 10,000-cycle economy springs most companies use as their default. We don't even stock 10,000-cycle springs. I stopped carrying them years ago because they're not the right part for this climate. The 20,000-cycle spring costs us more, yes, but the difference to you is relatively small — maybe $40 to $80 more per spring — and you're getting double the lifespan plus corrosion resistance that matters enormously in Central Oregon's conditions. If someone quotes you significantly less than $300 for a pair, ask them what cycle rating the springs are. Ask if they're galvanized. The answer will usually tell you why the price is lower.
Let me break down the math on replacing both vs. replacing one. Single spring replacement: $250 to $350 for one visit. When the second spring breaks three to six months later — and it will — that's another $250 to $350 for a second visit. Total: $500 to $700. Replacing both springs in one visit: $300 to $500. You save $200 to $300 and you skip the second breakdown, the second phone call, the second morning trapped in your garage. I don't understand why anyone would choose the more expensive, less convenient option, but some companies will happily sell you just the one spring because it's an easier quote to close. They know they'll be back.
Every spring replacement we do comes with a 2-year warranty on parts and labor. If a spring fails within that window, we replace it at no cost — including the service call. I can offer that warranty confidently because of the springs we use and the care we put into the installation. When you use properly sized 20,000-cycle galvanized springs, install them correctly, and balance the door right, warranty claims almost never happen.
For a broader look at garage door repair pricing beyond springs, we put together a detailed cost guide for garage door repair in Bend that covers everything from opener repair to panel replacement.
Warning Signs, and What to Do Before It's an Emergency
Most springs don't fail without warning. In the weeks before a break, there are signals — things you can see, hear, and feel if you're paying attention. Catching these early means you schedule a replacement on a Tuesday afternoon instead of dealing with it at six in the morning on the coldest day of the year.
The simplest test is the balance test. Disconnect the opener by pulling the red emergency release cord. Lift the door manually to about waist height — the halfway point — and let go. A properly balanced door with healthy springs stays put. It should just hover there. If it drifts down, the springs are losing tension. If it drops fast, failure is close. Do this test every few months. It takes thirty seconds and tells you more than anything else.
Other signs: the door feels noticeably heavier when you lift it manually. The opener seems to struggle or takes longer to open the door than it used to. You hear squeaking, popping, or grinding from the spring area when the door moves — that's either dry coils, which lubrication can fix, or micro-fractures developing in the metal, which nothing fixes except replacement. If you look at the torsion spring above your door and see a visible gap between the coils — a separation where the coils have pulled apart — the spring has already partially fractured and could snap at any moment. Don't open or close the door. Call us immediately.
The opener can tip you off too. Modern openers have force-limit settings that cause them to stop and reverse if the door resists too much. If your opener is stopping mid-cycle or reversing when there's no obstruction, the spring may have weakened to the point where the door's effective weight exceeds the opener's force setting. The opener is doing its job — it's protecting itself and you. But it's also telling you the spring isn't carrying its share of the load anymore.
Proactive replacement costs the same as emergency replacement. Same parts, same labor, same price. The only difference is you choose the day and time. Regular garage door maintenance includes a spring inspection — we check tension, look for corrosion, test balance, and tell you honestly how much life your springs have left. If they're getting close, we'll let you know so you can plan ahead instead of reacting to a bang at 6 AM.
If your spring already broke and you're reading this on your phone in the garage right now — don't try to open the door manually. Without spring counterbalance, you'd be lifting the full weight of the door by yourself. People hurt their backs, drop doors on themselves, get fingers crushed. Call us. We carry the most common residential spring sizes on every service truck, and for homes in Bend, Redmond, Sisters, Sunriver, or La Pine, we can typically be there same day. Most replacements take 45 minutes to an hour once we're on site. If you're in an emergency situation and absolutely need your car out right now, call us and we'll walk you through the safest way to handle it over the phone while we're on the way.
One last thing. I get asked whether it makes sense to add a second spring to a single-spring door. It depends on the door. Most single-car doors — 8-by-7, 9-by-7 — are designed for one torsion spring sized to the full weight. That's fine. But if your double-car door has only one spring, it's working at maximum capacity on every single cycle and it will fail sooner. Adding a second spring shares the load, extends the life of both, and gives you smoother operation. Worth asking about.
A note about what we actually do during a spring replacement, because it's more than just swapping parts. After we install the new springs, we rebalance the entire door — adjusting tension until the door holds steady at any position you leave it. Then we adjust your opener's force and travel limit settings to match the new spring tension, which keeps the opener from overworking and ensures the auto-reverse safety feature functions correctly. That auto-reverse matters if you have kids, pets, or anyone who could be in the door's path. We lubricate the spring assembly, the bearing plates, the torsion shaft, and every moving part connected to the system. We run the door through a full set of open-close cycles manually and with the opener, testing everything. The whole job typically takes 45 minutes to an hour, start to finish. We don't need to come back, and we don't leave until the door runs the way it should.
The bottom line on springs is this: they're the hardest-working part of your garage door, they operate under enormous tension, and Central Oregon's climate pushes them harder than most places in the country. Respect what they do. Watch for the warning signs. And when it's time, call someone who does this every day and does it right.
