Broken torsion or extension springs are one of the most common garage door problems in Massachusetts and New Hampshire homes. When a spring breaks, your door becomes inoperable—and dangerous to use. AB Garage Door provides same-day spring replacement service across MA & NH, including Boston, Waltham, Bellingham, Nashua, and Bedford. We use high-quality parts and stand behind our work with industry-leading warranties.
Watch for these warning signs that indicate it's time to call for professional service.
A sudden loud bang typically means a spring has snapped. The door may still open with the opener, but it's unsafe to use.
If your door suddenly feels much heavier than normal, the springs are likely broken or failing and not providing proper counterbalance.
One side rising faster than the other indicates a spring imbalance—one spring may be broken while the other is intact.
Torsion springs develop a visible gap when broken. Extension springs may hang loosely or show separation.
If your door drifts down when you try to leave it open, the springs can't hold the weight—a sign of failure or wear.
Uneven, jerky movement when opening/closing indicates springs are worn and providing inconsistent tension.
Torsion springs are mounted above the door on a horizontal steel shaft. They work by winding and unwinding stored torque to counterbalance the weight of the door. This is the most common spring configuration found in Massachusetts and New Hampshire homes built in the last 30 years. A standard torsion spring is rated for 10,000–15,000 open/close cycles — roughly 7–10 years of average use. When a torsion spring snaps, it releases that stored energy instantly, which is why a broken garage door spring sounds like a gunshot and why DIY replacement is genuinely dangerous. We carry multiple wire sizes and spring lengths to match your door’s weight precisely.

Applied for any of the springs options. This is the most expensive spring configuration. A high cycle torsion spring starts from 15,000 open/close cycles — and can get to 70,000 or 100,000 life cycles. We carry multiple wire sizes and spring lengths to match your door’s weight precisely.
Extension springs are mounted on both sides of the door track, running horizontally or at an angle. They stretch (extend) as the door closes and contract as it opens. This is an older-style system still found in many ranch-style and colonial homes across Massachusetts. Extension springs are generally lower cost to replace, and we always replace them in pairs — if one has broken, the other is at the same wear point and will fail soon. Each set includes safety cables threaded through the spring to contain it if it snaps.
What to Expect
Moderate
Spring replacement cost depends on spring type, door size, and whether you need single or double replacement. We always recommend replacing both springs together—if one has failed, the other is likely near the end of its life too.
We secure the door and release tension safely
Inspect springs, door balance, and hardware
Install new springs with proper calibration
Fine-tune tension and test door operation
Every year, homeowners searching for garage door spring repair near me end up attempting the job themselves after watching a video online. Some succeed. Many do not — and the consequences can be severe. Torsion spring replacement is one of the most physically dangerous residential repair tasks that exists, and it is consistently cited in emergency room visit statistics for home improvement injuries.
A standard residential torsion spring stores between 150 and 300 foot-pounds of torque when fully wound. That energy has to go somewhere when it’s released — ideally through the controlled rotation of the shaft and cables to lift your door. When it releases unexpectedly during a DIY attempt, it transfers into whatever is in its path. This can mean a broken wrist, a shattered face shield, or worse. The Consumer Product Safety Commission has documented fatalities from DIY garage door torsion spring replacement, not just injuries.
Proper garage door spring replacement is not simply a matter of removing an old spring and installing a new one. The process requires:
