It's 7:15 in the morning. You hit the opener button and nothing happens — or you hear a loud bang and the door goes dead. That's almost always a broken spring. It's the most common garage door failure in Massachusetts, and it sidelines your car until it's fixed. Here's what it costs, how long it takes, and why you should never attempt it yourself.
Torsion Springs vs. Extension Springs: What You Have
Before we get to cost, you need to know which type of spring system your door uses. The fix is different, the parts are different, and the risk profile is different.
Torsion Springs
Torsion springs mount horizontally above the door opening on a metal shaft. When the door closes, the spring winds up under tension. When it opens, the spring unwinds and uses that stored energy to help lift the door's weight. Most doors installed in the last 15–20 years use torsion springs.
- Located above the door, centered on a metal rod
- Single or double spring depending on door weight
- More durable — typically rated 10,000–20,000 cycles
- When they break, they make a sound like a gunshot
Extension Springs
Extension springs run along the horizontal tracks on each side of the door. They stretch and contract as the door moves. Common on older doors and lighter single-car doors.
- Located along the side tracks, one on each side
- Less expensive but wear out faster — 7,000–10,000 cycles typical
- Always replace in pairs even if only one breaks
- Safety cables should run through the center — if yours don't, this is a hazard
Spring Replacement Cost in Massachusetts
Spring replacement pricing depends on spring type, door size, and whether you also need hardware or cable work done at the same time.
| Service | Typical Cost (MA) |
|---|---|
| Single torsion spring (1-car door) | $175–$280 |
| Double torsion spring (2-car door) | $220–$360 |
| Extension springs (pair, with cables) | $150–$240 |
| High-cycle spring upgrade (25,000+ cycles) | +$60–$120 |
| Cable replacement (per side) | $75–$130 |
Our standard spring replacement includes same-day service for calls placed before noon on weekdays, parts and labor, door rebalancing after install, and a full safety check. There's no diagnostic fee added on top of the repair when we proceed with the work.
Worth noting: If your door is 12+ years old and has the original springs, consider upgrading to high-cycle springs while we're there. The cost delta is $60–$120, and you won't be calling us again in 3 years when the springs reach end of life.
Why DIY Spring Replacement Is Dangerous
We'll be direct about this: garage door spring replacement is not a DIY job. It is consistently ranked as one of the most dangerous home repair tasks, and the physics involved are why.
A torsion spring on a standard two-car door stores roughly 400 foot-pounds of torque when fully wound. If you release that energy incorrectly — wrong tools, worn winding bars slipping, incorrect sequence — the spring can unwind explosively. People have lost fingers, broken wrists, and taken serious facial injuries from spring failures during DIY repairs.
Real risk, not a liability disclaimer: The Consumer Product Safety Commission estimates 20,000+ garage door-related injuries annually. A disproportionate number involve spring work. Proper torsion spring replacement requires calibrated winding bars, knowledge of the correct number of turns by door height, and the physical discipline to maintain control under load. Watching a YouTube video is not equivalent preparation.
The cost of professional spring replacement in Massachusetts is $175–$360. That's the number to weigh against the risk. It's also significantly less than an ER visit.
How Long Does Spring Replacement Take?
A standard single torsion spring replacement takes 45–75 minutes for a professional technician. Double springs on a heavier door run 60–90 minutes. We do same-day service for most calls received before noon.
Extension spring replacement is slightly faster — typically 30–60 minutes — because the springs are more accessible and the cable work is straightforward when the hardware is in good condition.
Signs Your Spring Is About to Fail
Springs don't always fail all at once. Here's what to watch for before the loud bang wakes you up:
- Door feels heavy: If your door feels unusually heavy when manually lifting it, the spring tension is degraded.
- Visible gap in the spring: A torsion spring with a visible separation or gap is broken. Don't operate the door.
- Jerky or uneven movement: Especially on two-car doors with dual springs — one failing causes the door to pull to one side.
- Squeaking or grinding: Metal fatigue and corrosion before failure. Lubrication can extend life, but only delays the inevitable.
- Door won't stay open: Springs provide counterbalance. A failing spring means insufficient counterbalance.
Spring Lifespan in Massachusetts
Standard springs are rated at 10,000 cycles. A cycle is one open plus one close. If you use your garage door four times per day (typical for a family), that's 1,460 cycles per year — meaning standard springs last roughly 6–7 years.
High-cycle springs (rated 25,000–50,000 cycles) cost more upfront but easily last 15–20 years under the same usage pattern. For most homeowners, the upgrade pays for itself in avoided service calls within 5–8 years.
New England winters shorten spring life due to thermal cycling — cold metal contracts and expands repeatedly, accelerating metal fatigue. If your garage is unheated and exposed to full Massachusetts winters, expect to be on the lower end of the lifespan range.
When to Call
Call immediately if: your spring has an obvious break or gap, your door won't open or opens only partially, or you hear any grinding or popping during operation.
Don't continue operating a door with a broken spring — you risk damaging the opener motor, the cables, or the drums. Most opener motors are not designed to lift a door without spring assistance, and forcing them to do so shortens their lifespan significantly.
