Garage Door Springs in Somersworth: Types, How They Work & Why It Matters
7 min read
Garage door springs fall into two main categories: torsion and extension. A torsion spring winds tightly above your door and unwinds to lift it. An extension spring stretches and contracts on either side. Both carry extreme tension. When one fails, your door becomes a safety hazard, not just an inconvenience.
I've responded to homes where a snapped spring sent metal shards into a parked car. I've seen fingers caught, faces injured, and worse. Understanding what's holding up that 400-pound door matters more than most people realize.
How Torsion Springs Work (and Why They're Standard)
Torsion springs are the workhorses of modern garage doors. A steel rod runs horizontally above the door opening. Two springs wrap around it, storing rotational energy. When you press the opener button, that wound energy releases, counterbalancing the door's weight so the motor lifts it smoothly.
Most residential doors in Somersworth rely on one or two torsion springs rated for 7 to 9 years under normal use. They don't just wear out randomly. Each cycle (opening and closing) counts as one cycle. A spring rated for 10,000 cycles will fail faster in a busy household. Temperature swings in New England winters accelerate that failure. Cold metal becomes brittle. Springs snap without warning.
The danger is real. A torsion spring under full tension carries roughly 200 pounds of force per side. When it breaks, that energy releases violently. The door can drop suddenly. The cable can whip free. Fingers, hands, and heads have been seriously injured.
Extension Springs: The Older, Riskier Alternative
Extension springs mount on each side of the door frame. They stretch as the door opens and contract as it closes. Older homes sometimes still have these, and while they work, they carry a higher safety risk.
When an extension spring snaps, the door on that side drops faster than the other. The door tilts, jamming in the tracks. Worse, extension springs lack safety cables in some installations. A cable failure means the spring end whips across the garage. I've seen those springs embed themselves in drywall.

Spring Failure: Cost and Timeline
A snapped spring won't fix itself. Attempting a DIY repair is dangerous. The remaining spring still carries full tension. You can't safely adjust or replace it without specialized tools and knowledge.
Professional replacement costs between $200 and $400 per spring, depending on the type and your door's weight. That estimate includes labor, materials, and safety testing. Delaying the repair doesn't save money. It risks your door jamming permanently, trapping your car inside and leaving your home vulnerable.

Prevention and Early Warning Signs
Springs don't fail without notice. Listen for these signals:
A loud creaking or squeaking above the door suggests metal fatigue. The door may open unevenly, with one side rising faster than the other. You might notice the door feeling heavier, requiring the opener to work harder. Some doors develop a slight bounce at the top of the opening cycle.
These are your window to act. A worn spring can be replaced before it breaks. Preventive maintenance is cheaper and infinitely safer than emergency calls and sudden failures.

Frequently Asked Questions
How long do garage door springs last? Torsion springs typically last 7 to 9 years with standard use (one cycle per day). Extension springs may last 5 to 7 years. Lifespan depends on climate, usage frequency, and maintenance.
Can I replace a garage door spring myself? No. Springs carry extreme tension. Improper release can cause serious injury. Professional technicians use specialized equipment and follow safety protocols. DIY attempts void warranties and risk severe harm.
What's the difference between torsion and extension springs? Torsion springs wind around a rod above the door and store rotational energy. Extension springs stretch on both sides of the frame. Torsion springs are safer, more durable, and standard in modern installations.
How much does a snapped spring cost to fix? Expect $200 to $400 for professional replacement, including labor and parts. Costs vary based on spring type, door weight, and whether both springs need replacement.
Why do garage door springs fail in winter? Cold temperatures make metal brittle and reduce its flexibility. Combined with seasonal use changes and existing wear, winter accelerates spring failure rates in New England.
