Garage Door Spring Types in Monrovia: Torsion vs. Extension Explained
2026-06-30 7 min read
Here's what most homeowners don't realize about garage door springs: the type you have matters far more than the brand. A torsion spring and an extension spring look nothing alike, cost differently, and fail in completely different ways. Picking the wrong replacement can waste hundreds of dollars and leave your door unsafe. We'll walk you through both types so you can make an informed decision without getting upsold.
What Are Garage Door Springs, and Why They Matter
Your garage door weighs 300 to 500 pounds. Springs counterbalance that weight, making your opener's job manageable and your door safe to use. Without functioning springs, your door becomes a hazard. A snapped spring won't just leave you stranded; it can crash down and cause serious injury or property damage. See our guide on garage door cost & pricing in monrovia: an honest breakdown.
Springs don't last forever. Most last between 7 to 9 years, depending on use and climate. Monrovia's heat and sun accelerate wear, so yours may need replacement sooner than homeowners in cooler regions. The good news? Knowing which type you have lets you budget accurately and avoid panic repairs.
Torsion Springs: The Most Common Type
Torsion springs sit above your garage door, centered on a metal rod. They twist (or torque) to lift the door. Most modern homes use torsion springs because they're durable, precise, and safer than alternatives. Read about garage door maintenance in monrovia: keep it running smoothly.
Torsion springs come in single or double configurations. A single spring handles lighter doors; double springs support heavier ones. When one fails, the other can't compensate, so your door becomes immobile.
The cost to replace a torsion spring typically runs between $200 and $400 per spring, plus labor. That's why getting an accurate estimate matters before committing. Garage Door Monrovia offers free assessments so you won't face surprise charges.
Extension Springs: The Budget Option (With Tradeoffs)
Extension springs sit on either side of your door, above the horizontal tracks. They stretch to lift the door, then retract as it closes. Older homes and lighter garage doors often use extension springs.
Extension springs are cheaper upfront (usually $100 to $200 per spring), but they require safety cables running through their center. Without those cables, a snapped extension spring can whip across your garage with dangerous force. If your extension springs are aging, replacing both at the same time prevents one from failing while the other still works.
How to Know Which Type You Have
Walk into your garage and look above the door. If you see a tightly wound spring running horizontally across the center, you have a torsion spring. If you see two springs on either side of the door running vertically along the tracks, those are extension springs.

Cost Comparison and Hidden Expenses
A single torsion spring replacement runs $200 to $400. Extension springs cost less per unit but may need two replaced simultaneously. Labor adds $100 to $200 to either job, depending on complexity.
What homeowners often overlook: a snapped spring sometimes damages other components. Your door's cables, pulleys, or rollers may need attention too. That's why a thorough diagnostic is crucial before you authorize work. Our team won't recommend unnecessary repairs, but we will flag real safety issues that could cost more if ignored.

Preventing Premature Spring Failure
Regular maintenance reduces strain on springs. Lubricating hinges, rollers, and tracks keeps your door running smoothly, which means springs work less hard. A well-maintained door can help springs reach or exceed their 7 to 9 year lifespan.
Monrovia's intense sun and heat also degrade springs faster than normal wear. Heat causes metal to expand and contract, weakening springs over time. Garage door maintenance in Monrovia: Stop costly repairs before they start covers seasonal care steps that protect your springs and other components.
When to Replace vs. When to Repair
A single snapped spring always requires replacement. You cannot repair a broken spring safely. If only one spring has failed and the other is in good condition, you can replace just the broken one, though many pros recommend replacing both to avoid a second failure soon after.
If your door is over 10 years old and both springs show rust or corrosion, replacing both at once saves money on labor and future emergency calls. If you're unsure, schedule a free quote with Garage Door Monrovia and let a technician recommend the best approach for your situation.

Frequently Asked Questions
What's the difference between torsion and extension springs? Torsion springs twist horizontally above the door. Extension springs stretch vertically on either side. Torsion springs are safer and more durable; extension springs are cheaper upfront but require safety cables.
How long do garage door springs last? Most springs last 7 to 9 years with normal use. Monrovia's heat and sun can shorten this lifespan. Regular maintenance and proper lubrication help springs reach their full lifespan.
Can I replace just one spring if the other is still working? Technically yes, but not recommended. Both springs experience similar wear and stress. Replacing both at once prevents a second failure within months and reduces total labor costs.
How much does spring replacement cost in Monrovia? Torsion springs cost $200 to $400 each plus $100 to $200 labor. Extension springs cost $100 to $200 each. Final cost depends on your door weight, spring type, and any additional repairs needed.
