Garage Door Springs in Wilton: Torsion vs. Extension Explained
2026-06-09
Your garage door has one or two springs holding roughly 400 pounds of weight. When they snap, your door won't open. The two main types are torsion and extension springs. Torsion springs sit above the door and twist to lift it. Extension springs run along the sides and stretch as the door opens. Understanding which you have helps you know what to expect when repair time comes.
What Are Torsion Springs?
Torsion springs are the workhorse of most residential garage doors in Wilton and across New England. They mount horizontally above the door on a metal shaft. When you open the door, the spring winds tightly, storing energy. That stored tension does the heavy lifting, not your opener motor.
These springs typically last 7 to 9 years with regular use. A typical home opens and closes the door 3 to 5 times daily. That's roughly 1,000 to 1,500 cycles per year. Over time, the metal fatigues. You'll notice the door feeling heavier or your opener working harder before it finally snaps.
One major advantage: torsion springs are safer. They're contained above the door, so if they break, nothing flies across the garage. That containment also means they're less likely to damage your car or injure someone nearby.
What Are Extension Springs?
Extension springs work differently. They're installed on both sides of the door opening, parallel to the horizontal tracks. As your door opens, these springs stretch and extend, pulling cables that help lift the weight.
Extension springs are cheaper upfront than torsion springs. Many older homes and some budget builds use them. However, they have downsides. When a snapped spring happens on an extension system, the cable can snap too and whip around the garage. That's dangerous. If you have extension springs and they fail, treating it as an emergency is wise.
Extension springs also tend to wear faster, sometimes failing in 5 to 7 years. In cold Wilton winters, the metal becomes brittle and more prone to breaking.

Cost and Replacement Estimate
The cost varies based on your spring type and door size. A torsion spring replacement typically runs $150 to $300 per spring, plus labor. Extension springs cost $100 to $200 each. Most doors have at least one spring, but larger or heavier doors might need two.
Labor is where the real expense sits. Spring replacement requires special tools, knowledge of proper tension, and safety precautions. A professional technician at Wilton Garage Doors can handle this in under an hour. A DIY attempt often ends with injury or a broken opener.
Don't skip the estimate step. When you call for a same-day inspection, we measure your door, identify your spring type, and give you an honest price before any work starts. No surprises, no upsells.

When Do Springs Need Replacement?
A snapped spring is the obvious sign. Your door either won't open at all or only opens a few inches before stopping. If you hear a loud bang from the garage, that's usually a spring breaking under tension.
Other warning signs appear before the snap. The door feels heavier than normal. The opener struggles or hums without opening the door. You see rust or visible damage on the spring. Any of these warrant a professional inspection.
Winter is a common time for failures in our region. Cold metal becomes more brittle. If your springs are already 7+ years old heading into January, replacement now prevents a January breakdown when you need your garage most.

Choosing Professional Repair
Replacing garage door springs is not a homeowner DIY project. The springs are under extreme tension. Improper release can cause serious injury. The tension must be set precisely, or your door won't balance and your opener will wear out prematurely.
Our team at Wilton Garage Doors uses specialized equipment and follows safety protocols every time. We inspect the entire system while we're there, checking cables, pulleys, and opener condition.

Frequently Asked Questions
How long do garage door springs last? Torsion springs typically last 7 to 9 years with normal use. Extension springs wear faster, often failing in 5 to 7 years. Lifespan depends on opening frequency, climate, and maintenance.
Can I replace a garage door spring myself? No. Springs are under extreme tension and can cause serious injury if mishandled. Professional replacement is safer and ensures proper tension and balance for your door and opener.
What's the difference between torsion and extension springs? Torsion springs mount above the door and twist to lift weight. Extension springs run beside the door and stretch. Torsion is safer and more durable; extension is cheaper upfront but wears faster.
How much does spring replacement cost? Torsion spring replacement ranges from $150 to $300 per spring plus labor. Extension springs cost $100 to $200 each. A complete job typically runs $250 to $500 including labor and inspection.
Should I replace both springs if only one breaks? Yes, we recommend it. If one spring failed after 7 years of use, the other is near the end of its life too. Replacing both now prevents a second failure weeks later.
