Your garage door relies on springs to lift a structure that can weigh 300 to 500 pounds. Two main types do this work: torsion and extension springs. Knowing which one you have saves you money when repair time comes, and helps you avoid overpaying for a replacement you don't need.
Torsion springs wind tightly around a shaft above your garage door opening. When the door closes, these springs twist and store energy. When you open the door, that stored energy unwinds and helps lift the weight. Most residential doors in El Cajon use torsion springs because they're durable, compact, and safer to work with.
Extension springs hang vertically on each side of your door opening. They stretch and contract as your door moves up and down. They're less common in modern homes but still found on older installations. Extension springs take up more space and require safety cables to catch them if they snap.
The key difference: torsion springs twist; extension springs stretch. This affects how long they last, what they cost to replace, and how dangerous a failure becomes.
Both types typically last 7 to 9 years with normal use, assuming your door opens and closes about 3 to 5 times daily. If you're opening and closing more often (like a contractor with a workshop), springs wear faster. A snapped spring usually means the whole thing needs replacement, not a patch.
Torsion springs fail predictably. Extension springs can break suddenly with more violence, which is why the safety cables matter. If an extension spring snaps without cables in place, the door can crash down dangerously.

Torsion springs generally cost less than extension springs because they're easier to install and more common. However, a snapped spring repair isn't just about the spring itself. Labor, expertise, and safety matter.
Never attempt DIY spring replacement. These components are under extreme tension and can cause serious injury. A licensed professional will assess the damage, confirm which type you have, and provide an estimate. If you're curious about typical pricing before calling, we've broken down how to avoid overpaying on spring repair costs.
Spring failure isn't always sudden. Sometimes your door feels heavier, moves slower, or makes grinding sounds. Catching these early signs lets you schedule service on your timeline instead of facing an emergency repair.
Regular maintenance catches spring wear before it becomes a crisis. A tune-up that costs $100 to $150 can extend spring life and catch other problems. Compare that to a same-day emergency repair that might cost significantly more, especially outside business hours.
Our maintenance guide explains why a tune-up costs far less than a repair.

What happens if a garage door spring snaps while the door is open? The door won't fall because it's already in the open position. However, you won't be able to close it safely without a working spring. Call a professional immediately; attempting manual closure risks injury and further damage.
Can I replace just one spring if I have two? Technically yes, but both springs wear at the same rate. Replacing only one while the other is near failure means a second emergency repair soon after. Most professionals recommend replacing both at once to save time and money.
Is a torsion spring safer than an extension spring? Torsion springs are generally safer because they're enclosed and controlled. Extension springs can snap with more force and require safety cables. If you have extension springs, ensure cables are in place and inspect them yearly.
How much does a garage door spring cost in El Cajon? Torsion springs typically range from $150 to $300 per spring, plus labor. Extension springs cost slightly less per unit but may require additional hardware. Labor adds $150 to $300 depending on difficulty. Get a specific estimate for your door.
Should I replace springs before they break? If springs are 7 to 9 years old and showing wear signs, replacing them proactively makes sense. If they're younger and working fine, maintenance is enough. A professional inspection helps you decide.
