A customer called last Tuesday with a loud bang from their garage. The door wouldn't budge. A snapped spring. Within an hour, I was at their Reading home. This happens more often than homeowners expect. Springs are the hardest-working part of any garage door system, and when they fail, the whole mechanism locks up.
Your garage door weighs 300 to 500 pounds. That's roughly the weight of three grown adults. Springs don't lift the door directly. Instead, they counterbalance that weight, so your opener only needs to move the door horizontally along the tracks. Without springs, your opener would burn out in weeks. See our guide: Garage Door Springs in Reading.
Two types handle this job: torsion springs sit above the door on a metal rod, twisting to store and release energy. Extension springs run along the sides of the door, stretching and contracting. Most residential doors in Reading use torsion springs because they're more durable and safer, though both fail eventually.
Springs are rated for a certain number of cycles. One cycle equals one full open and close. Quality springs last 7 to 9 years with typical residential use (about 3 to 5 cycles daily). If your door cycles 10 times daily, springs wear out faster. See our guide: Garage Door Springs in Reading, MA.
Metal fatigues. Every time a spring winds and unwinds, tiny cracks form at the molecular level. After thousands of cycles, those cracks join together and the spring breaks. Sometimes it's sudden and loud. Sometimes you'll notice the door getting harder to open in the weeks before failure.
Rust accelerates this process. Massachusetts humidity, salt from winter roads, and poor garage ventilation all speed corrosion. A rusted spring is a weakened spring. That's why maintenance matters. We cover Stoneham, Winchester, and the greater Boston area, where salt exposure is unavoidable.
Another culprit: mismatched springs. If one spring breaks and only one gets replaced, the surviving spring carries uneven load. It fails sooner. Both springs should always be replaced together, even if only one snapped.
A snapped spring means your door won't open. Period. Your opener can't do the work alone. Trying to force it risks damaging the tracks, rollers, and opener itself. That's a much costlier repair.
You need professional replacement the same day if possible. Why? Because garage doors are heavy, springs are under extreme tension (up to 300 pounds of force), and improper installation can injure someone or break the door.

Spring replacement cost depends on the type, quality, and whether one or both need replacement. We always replace both to ensure balanced operation and prevent premature failure of the remaining spring.
Our pricing reflects honest labor and quality parts. You'll pay for the springs themselves, the labor to remove old springs safely, install new ones, test the door balance, and adjust the opener if needed. That's a real job, not a quick swap.

Springs operate under extreme tension. Mishandling a torsion spring can cause serious injury. A snapped spring under tension can whip across the garage. Extension springs can snap with enough force to break bones or cause eye injury.
Professional installation also ensures proper spring sizing for your specific door weight and cycle frequency. Wrong springs lead to premature failure or unsafe operation.
You can't prevent springs from wearing out, but you can extend their lifespan. Regular lubrication of springs, tracks, and rollers reduces friction and rust. Keeping your garage dry helps too.

If your door isn't opening, or you've noticed it getting harder to operate, don't ignore it. A failing spring often shows warning signs weeks before it snaps completely. Springs are the most common failure point on garage doors.

How long do garage door springs last? Quality torsion springs last 7 to 9 years with normal residential use (3 to 5 cycles daily). Heavy use or poor maintenance shortens lifespan. Both springs should be replaced together to ensure balanced door operation.
Can I replace one spring instead of two? No. If one spring fails, replace both. A single new spring paired with an aged, weakened spring creates imbalance. The older spring fails within months, requiring a second service call and doubling your cost.
What's the difference between torsion and extension springs? Torsion springs twist above the door on a rod and handle heavier doors safely. Extension springs stretch along the sides and suit lighter doors. Torsion springs are more common in residential garages and typically safer.
Why does a snapped spring cost more than expected? You're paying for safety and expertise. Professional installation requires proper tools, tension management, and balance testing. Improper installation risks injury or damage to the door, opener, and home.
How do I know if my springs are failing? Signs include the door opening or closing slower, jerking during movement, visible rust or cracks on springs, or the opener struggling more than usual. Any of these warrant an inspection before a spring snaps completely.
