Torsion vs. Extension Springs in Dixon: Which Type Do You Have?
2026-09-11 7 min read
Your garage door probably works without you thinking about it. Until one morning it doesn't. When that happens, nine times out of ten the culprit is a snapped spring. But before you panic about repair costs, you need to know what type of spring you're dealing with. Torsion and extension springs work differently, cost different amounts, and require different expertise to replace safely.
What Are Garage Door Springs?
Springs do the heavy lifting for your garage door. A standard door weighs 300 to 500 pounds. Without springs, opening it by hand would be nearly impossible. Springs store and release energy, making that heavy door feel light and manageable. They're under constant tension, which means they wear out over time. Most springs last 7 to 9 years with normal use, depending on how often you open and close your door.
The two main types serve the same purpose but work in completely different ways. Understanding which one you have matters because replacement costs and safety concerns differ significantly.
Torsion Springs: The Overhead Powerhouse
Torsion springs sit horizontally above your garage door opening. They twist and rotate to lift the door, storing energy as they wind up. When you open the door, they unwind and release that stored energy. Think of them like a wound-up clock spring, just much more powerful.
Torsion springs are the most common type in modern garages. They're more durable than extension springs and typically last longer. A snapped torsion spring usually means the entire spring needs replacement, not just repair. The cost runs higher than extension springs, but homeowners appreciate the smoother operation and longer lifespan.
One big advantage: torsion springs keep both sides of the door balanced during operation. This means less stress on your garage door opener and tracks. If you have a newer door or a heavier custom installation, torsion springs are probably what you're using.
Extension Springs: The Sides Solution
Extension springs hang vertically on both sides of your garage door opening. They stretch and contract to lift the door, extending when the door closes and contracting when it opens. Picture two rubber bands on either side of the door, pulling upward in unison.
Extension springs are cheaper than torsion springs, which is why older garage doors and budget installations often use them. However, they wear out faster. If one side snaps, the other side typically fails soon after because they share the load unevenly once one breaks.
Extension springs require safety cables running through their center. These cables catch a snapped spring before it whips across your garage. Without them, a snapped extension spring becomes a dangerous projectile. This is why DIY replacement is not recommended for either type.

How to Identify Your Spring Type
Look above your garage door from inside the garage. Is there a horizontal spring running across the top center? That's torsion. Do you see springs hanging on the left and right sides? Those are extension springs.
Don't touch the springs themselves. They're under extreme tension and can cause serious injury. If you suspect a snapped spring, stop using your door immediately. A broken spring makes your opener work overtime, risking motor burnout and expensive repair bills down the line.
Cost Differences and Replacement
Torsion spring replacement typically costs more than extension springs because the installation is more complex and requires specialized equipment. Extension springs cost less upfront, but you'll likely replace them more often. Over a decade, the total cost often evens out, but torsion wins on convenience and safety.

Why You Shouldn't DIY Spring Replacement
Garage door springs operate under 200 to 400 pounds of tension. A snapped spring releases that energy instantly. Even experienced mechanics have been seriously injured attempting DIY spring replacement. Professional technicians have the right tools, training, and insurance to do this safely.
Replacing springs yourself might save a few hundred dollars, but one mistake could cost you thousands in emergency room bills or permanent injury. Our team at Garage Door Company Dixon handles spring replacement as routine work. We schedule same-day service whenever possible and stand behind our work with warranties.
Maintenance Extends Spring Life
Regular lubrication and inspection catch problems early. Springs that get monthly lubrication often last longer than neglected ones. If you notice your door moving slower than usual or requiring extra effort, springs may be weakening. Don't wait for a complete failure.

When a spring fails, call a professional immediately. The longer you wait, the more stress transfers to other components. Contact us at (510) 296-3863 or schedule a free estimate to get your door back in working order today.
Frequently Asked Questions
How long do garage door springs typically last? Most garage door springs last between 7 and 9 years under normal residential use. Frequency of door cycles, weather conditions, and maintenance affect actual lifespan. Regular lubrication can extend life slightly, but springs eventually wear out regardless.
Can I replace one spring if the other is still working? For extension springs, we recommend replacing both sides at once, even if only one snapped. The remaining spring has likely weakened similarly and will fail soon. Torsion springs are single units, so replacement is all or nothing.
What's the danger of a snapped spring? A snapped torsion spring loses its ability to support the door weight, forcing your opener to work much harder. A snapped extension spring can whip violently across your garage if safety cables fail. Both situations create safety hazards and risk costly secondary damage.
How much does spring replacement cost in Dixon? Extension spring replacement typically runs $150 to $300 per pair. Torsion springs cost $250 to $400 depending on door size and spring quality. Call (510) 296-3863 for a specific estimate based on your door's specifications.
Should I replace springs before they break? If springs are nearing the end of their expected lifespan (7 to 9 years) and showing warning signs, replacement before failure saves downtime and prevents secondary damage. However, replacing springs that still function is unnecessary. Our technicians can assess your springs and recommend the right timing.
