Your garage door relies on springs to lift a weight equivalent to a small car. Get the spring type wrong, and you're looking at a snapped spring, a stuck door, and an emergency repair bill. Let me walk you through the two main types: torsion and extension springs, how they differ, and which one sits above your door right now.
Torsion springs wind tightly around a metal rod mounted horizontally above your garage door opening. As your door opens, they twist (or torque) to counterbalance the weight. They unwind as the door closes.
Here's why they matter: torsion springs are the industry standard for residential garage doors in Wakefield and surrounding areas. They're precise, durable, and last 7 to 9 years with regular use. A typical home sees 3 to 5 door cycles per day, which means your torsion spring handles thousands of open/close cycles before fatigue sets in.
The mechanical advantage is cleaner too. Torsion springs provide smooth, controlled lifting. Your door won't jerk or drop suddenly if one spring weakens. That smooth operation keeps your garage door opener from burning out prematurely and protects the safety mechanisms that prevent accidents.
One critical detail: torsion springs are pre-tensioned. Installing or adjusting them without proper tools and training is genuinely dangerous. The stored energy can release violently if you make a mistake. Don't attempt this yourself.
Extension springs sit on both sides of your garage door, running parallel to the horizontal tracks. Unlike torsion springs, they extend and contract as your door moves. Think of them like two strong rubber bands pulling your door up.
Extension springs are cheaper upfront, which is why some older installations or budget-conscious builders chose them. They last 5 to 7 years typically, which is shorter than torsion springs. They're also noisier during operation and provide less balanced lifting force.
Here's the safety concern: when an extension spring snaps, your door can drop hard and fast. That's why extension springs should always have cable restraint systems attached. If a spring breaks and the restraint fails, your door becomes a 400-pound falling object. It's one of the leading causes of garage door injuries we see at Wakefield Garage Doors.
If you have extension springs and haven't had them inspected in 2 years, schedule service now. Learn more about why springs snap and what repairs cost in our detailed guide.

Stand in your garage and look at the space directly above your door. Do you see a single horizontal rod with a tightly coiled spring wound around it? That's torsion. Do you see a spring on each side of the door near the tracks? Those are extension springs.
Not sure? That's normal. Take a photo and reach out for a free estimate. We'll identify your spring type, assess its condition, and give you an honest cost breakdown within minutes.
Torsion spring replacement costs between $200 and $400 per spring, depending on the wire gauge and spring length. Extension springs run $100 to $200 each, but you usually need both sides replaced at the same time. Factoring in labor, a full torsion spring repair in Wakefield averages $400 to $600. Extension springs typically run $300 to $500 total.
Skip the replacement and you'll face a stuck door, potential safety hazards, and added strain on your opener. Preventive replacement is always cheaper than emergency service. Check our maintenance guide to stay ahead of spring failure.
If your door opens partway and stops, moves slowly, or hangs unevenly, a spring is failing. Don't open and close it repeatedly. Each cycle worsens the imbalance.
If you hear a loud bang or see a broken coil, stop using your door immediately. A snapped spring can't support the door weight safely. Schedule emergency service right away, or call us at (781) 332-4935 for same-day help.
Never attempt spring repair yourself. Even experienced homeowners miss critical safety steps. The cost of professional installation is worth the certainty that your door operates safely and your family stays protected.

How long do garage door springs typically last? Torsion springs last 7 to 9 years. Extension springs last 5 to 7 years. Lifespan depends on how often you use your door, local weather, and maintenance habits. Springs rated for higher cycle counts (like 10,000 cycles) last longer than standard springs.
Can I replace one spring if the other is fine? No. Springs work in pairs to balance your door weight equally. If one is worn, the other is close behind. Replacing only one causes uneven lifting, strains your opener, and creates safety risks. Replace both springs at the same time.
What causes a snapped spring? Rust, age, constant use, and sudden temperature changes all weaken springs. Rust eats away at the metal. Cycles cause metal fatigue. Cold weather makes steel more brittle. Regular inspection catches weak springs before they snap.
Is torsion or extension spring replacement more expensive? Torsion spring replacement typically costs more per spring but provides better performance and safety. Extension springs cost less initially but fail sooner and carry higher safety risks if a restraint cable fails.
Why shouldn't I use my garage door if a spring is broken? A broken spring removes the counterbalance force. Your opener tries to lift the full door weight, which can burn it out, cause the door to drop suddenly, and risk crushing anyone underneath. Use it only for emergencies, and only partially.
