In our years serving South Hamilton, we've seen this problem again and again: a homeowner hears a loud bang from the garage, the door won't budge, and panic sets in. Nine times out of ten, a garage door spring has snapped. These springs carry 200 to 400 pounds of tension and fail without warning. Understanding the two main types, torsion and extension springs, helps you recognize the danger and know when to call for help.
Your garage door weighs between 300 and 800 pounds. Without springs, it would be impossible to open by hand. Springs work in pairs and counterbalance the door's weight so the opener can lift it smoothly. Most residential doors in South Hamilton use one of two designs: torsion springs mounted above the door on a metal rod, or extension springs running along the sides inside the tracks.
Torsion springs are the industry standard in newer homes and commercial properties. They twist and unwind, storing mechanical energy. Extension springs stretch and contract, offering a simpler but less balanced design. Both types last roughly 7 to 9 years under normal use, though cycles matter more than time. A family opening and closing the door 4 to 8 times daily will see spring failure sooner than occasional users.
Torsion springs sit horizontally above the garage door opening on a metal shaft. When the door closes, these springs twist tighter, storing energy. When you open the door, that energy releases, lifting the weight. Because tension is concentrated on a single rod, torsion springs fail more predictably and safely than extension types.
If a torsion spring breaks, the door simply becomes very heavy. You won't be injured by a spring end whipping across the garage. This containment is why most new installations in South Hamilton use torsion designs. They're also more durable, lasting through more opening cycles before needing replacement.
The downside? Torsion spring repair costs more than extension springs. A new torsion spring typically runs $200 to $400 per spring, though pricing depends on door size and spring quality. Our complete garage door springs pricing guide breaks down these costs in detail for South Hamilton homeowners.
Extension springs hang vertically on each side of the door, below the horizontal tracks. As the door closes, these springs stretch. As it opens, they contract and help lift the load. Many older South Hamilton homes still use this setup because they're cheaper to install initially.
Here's the danger: when an extension spring snaps, the broken end can whip across the garage at high speed. This flying metal can cause serious injury or property damage. Safety cables run through these springs to catch them if they break, but cables wear out and sometimes fail themselves. If you have extension springs, check that safety cables are in place and replace them immediately if either spring snaps.

A snapped spring is obvious: the door won't open, or it opens unevenly and crashes down. But warning signs appear weeks before total failure. If your door feels heavier than usual when opening, makes a creaking noise at the top of each cycle, or hangs lower on one side, springs are weakening.
Don't attempt DIY replacement. Springs under extreme tension can cause serious injury or death if mishandled. A spring under load can release suddenly and break bones or cause fatal injuries. Our team at South Hamilton Garage Doors carries specialized tools and knows how to safely release tension before touching anything. Learn when to call us versus attempting repairs yourself to understand the full scope of what's safe to handle alone.

Can I still use my garage door if one spring is broken? No. A broken spring means the other spring carries double the load, and the door becomes dangerously heavy and unbalanced. Using it risks injury and further damage to the opener and tracks.
How long does spring replacement take? Most replacements take 1 to 2 hours from arrival to completion. Same-day service is usually available in South Hamilton. We'll call ahead to confirm timing when you schedule.
Do both springs need to be replaced at the same time? Yes. Springs wear together. If one has failed, the other is near the end of its life. Replacing both ensures balanced operation and prevents a second failure within weeks.
Are torsion springs safer than extension springs? Torsion springs are safer because they don't have exposed energy that whips outward when they break. Safety cables on extension springs can fail, creating hazard risk.
What's the lifespan of a garage door spring? Most springs last 7 to 9 years or roughly 10,000 opening cycles. Frequent use shortens lifespan. Well maintained springs may last longer, but they're not permanent.
