Most homeowners don't think about their garage door springs until something goes wrong. You hit the opener button, hear a loud bang, and suddenly the door won't budge. That bang is a snapped torsion spring, and it's one of the most common emergencies we handle here in Derry. Springs typically last 7 to 9 years depending on use, but when they fail, you're looking at an unexpected repair that can't wait.
Garage door springs fail for specific reasons, not by accident. Torsion springs live under constant tension. They counterbalance your door's weight, which usually ranges from 300 to 600 pounds. Every time you open or close, those springs are working. Over years, metal fatigue sets in. Temperature swings in New England make it worse. Winter cold makes metal brittle. Summer heat accelerates wear. Salt air near the coast (we service Salem, Exeter, and surrounding towns) adds corrosion.
The real culprit? Lack of maintenance. Springs need periodic lubrication. Without it, friction increases, metal stress increases, and failure comes early. I've seen springs last only 4 years when owners never had them serviced. Properly maintained springs get closer to that 7 to 9 year window.
Most residential doors in Derry use torsion springs. They're mounted above the door, centered on a shaft. You'll see two coils working together. Extension springs are older and found on some older homes. They run along the sides of the door and extend when the door opens. Both fail, but torsion failures are louder and more dramatic because of the sudden release of tension.
A snapped spring means your door opener can't lift the door. The motor will hum, strain, and stop. You're locked in or locked out. The door is a safety hazard because it no longer has balanced weight distribution. If one spring breaks on a two spring system, the other spring compensates unevenly, warping the tracks.
Don't try to manually lift the door. Don't keep running the opener. You risk damaging the opener motor and the door itself. This is a job for professionals.

Most homeowners ask the same question: what will this cost? A torsion spring replacement typically runs between $250 and $400 per spring, including labor. If both springs fail (it happens), you're looking at $500 to $800 total. The cost depends on spring size, door weight, and whether we're replacing one or both.
Why the range? Heavy commercial-grade doors need heavier springs. Standard residential doors are on the lower end. Installation time also factors in because springs must be wound and tensioned correctly for safety. Improper installation can cause springs to fail faster or create dangerous imbalances.
We've covered garage door springs in Derry: repair vs. replace and what you should know in detail elsewhere on our site. If you're deciding between repair and replacement for the entire door, that post breaks down the real decision points.
When a spring snaps, your garage is unusable. If you park inside, you can't leave for work. If your garage is your only entry point in winter, you're vulnerable to the elements. Same-day spring replacement isn't a luxury in Derry. It's practical necessity.
Our team carries torsion and extension springs on our trucks. We can diagnose and replace springs the same day you call. We also inspect the door, tracks, and opener to make sure nothing else was damaged by the spring failure.
Regular maintenance prevents most spring failures. Spring lubrication every 6 months reduces friction. Keeping the tracks clear prevents binding, which stresses springs. Visual inspection catches rust or corrosion early. If you want a full maintenance tune-up, our seasonal garage door maintenance guide walks through what you should expect each quarter.
If your garage door has safety features like auto-reverse or photo eyes, they won't help a snapped spring. The door simply won't move. But those safety features protect you during normal operation, and they're worth understanding. See our garage door safety guide on auto-reverse and photo eyes for more detail.
If your spring just snapped, stop. Don't force it. Call us at (978) 645-3493 for an immediate assessment. We'll tell you over the phone what we're likely to find, give you a cost estimate, and schedule a time that works for your schedule.
If you haven't had your springs serviced in over a year, they're due for an inspection. Small maintenance costs way less than emergency replacement. Get a free estimate by contacting us today, and let's make sure your springs aren't on borrowed time.
Garage Door Derry has handled hundreds of spring emergencies across Derry and the surrounding region. We know what fails, why it fails, and how to fix it fast without shortcuts.
How long do garage door springs last? Most torsion springs last 7 to 9 years with regular maintenance. Without lubrication and inspection, they may fail in 4 to 6 years. Heavy use (opening and closing 6+ times daily) accelerates wear.
Can I replace a garage door spring myself? We don't recommend it. Springs are under extreme tension. Improper installation can cause injury or equipment damage. Professional installation ensures safety, correct tensioning, and warranty coverage.
What causes a spring to snap suddenly? Metal fatigue from constant tension, rust from moisture, and lack of lubrication are the main causes. Temperature extremes in New England winters compound the stress on the metal coils.
Why does my garage door opener hum but the door won't open after a spring breaks? The opener motor is trying to lift a 400+ pound door without the spring's counterbalance. The door is too heavy for the motor to move alone. A snapped spring means the load is unbalanced and unsafe.
How much does a same-day spring replacement cost in Derry? Single spring replacement averages $250 to $400. Dual springs run $500 to $800. Cost depends on door weight, spring size, and whether additional repairs are needed after inspection.
