Most homeowners never think about garage door springs until one snaps. You hear a loud bang, your door won't budge, and suddenly you're facing an unexpected repair bill. The good news? Understanding what type of spring you have now saves you money later. Torsion and extension springs do the same job differently, and the cost to replace them varies significantly.
Your garage door weighs 300 to 500 pounds. Springs don't lift it directly. Instead, they counterbalance that weight, making the opener's job manageable. Without springs in good condition, your opener burns out fast. The door becomes a safety hazard. Springs last roughly 7 to 9 years under normal use, but that timeline shortens if you open and close your door 10 or more times daily.
Two spring types handle this load: torsion and extension springs. Each has different failure patterns, repair costs, and longevity. Knowing which one you have is your first step toward smart budgeting.
Torsion springs sit on a horizontal rod above your door opening. They twist (rotate) to store and release energy. One snapped torsion spring won't stop your door from opening, but you'll feel the difference. The opener strains. The door feels heavier. Your system works harder until the second spring fails.
Most modern garages in Monrovia use torsion springs because they're safer and more durable. They last longer than extension springs. A typical torsion spring replacement costs between $200 and $400, including labor. If both springs need replacement (which we recommend), budget $400 to $600 total. That investment covers parts, installation, and a safety inspection.
Torsion springs are harder to install yourself. The tension involved is dangerous. A miscalibrated spring can snap under pressure, injuring you or damaging your door. Learn why DIY replacement often costs more than professional service.
Extension springs run horizontally along each side of your door opening. They stretch to store energy and contract to release it. You'll find them on older garage doors and budget installations. They're cheaper upfront but fail faster.
One broken extension spring still allows your door to open, but unevenly. The door tilts. Cables strain. Without both springs working, you're weeks away from a second failure. Extension spring replacement costs $150 to $300 per side, or $300 to $600 for the pair. That sounds cheaper, but you'll replace them more often.
Extension springs last 5 to 7 years in regular use. Torsion springs last 7 to 9 years. Over a decade, torsion is the better financial choice because you're not replacing springs twice.

Stand in your garage and look above the door. Torsion springs sit in the center, running left to right. Extension springs hang along the walls on each side. If you see a thick coil rod in the middle with pulleys on both ends, that's torsion. If you see long springs stretching along the sides with hooks at the ends, that's extension.
Your garage door manual or the opener label will confirm the type if you're uncertain. When in doubt, call for a free estimate rather than guessing. A technician can assess both spring condition and your opener's strain in minutes.
A snapped spring doesn't mean your door is permanently stuck. But the longer you wait for replacement, the more expensive repairs become. Your opener compensates for missing spring tension by working harder. This burns out the motor, strains the cables, and can damage the garage door itself.
We've seen homeowners spend $800 on opener replacement when they could have spent $400 on springs six months earlier. Check our seasonal maintenance guide for warning signs.
Never adjust, replace, or even inspect springs yourself. The tension stored in a garage door spring can cause serious injury.

Garage Door Monrovia offers same-day service for broken springs. We'll identify whether you need torsion or extension replacement and give you an honest price with no surprise fees.
How do I know if my garage door spring is about to break? Listen for creaking, grinding, or popping sounds during operation. Your door may feel heavier or open more slowly. If one side sags while opening, a spring is likely failing. Call for an inspection before it snaps completely.
Can I replace just one spring if only one is broken? Technically yes, but we recommend replacing both. Springs wear together. The surviving spring is near the end of its life too. Replacing just one leaves you facing another repair within months, costing extra labor fees.
How long does spring replacement take? Professional replacement takes 1 to 2 hours per spring, depending on the type and your door's condition. We provide same-day service in most cases.
Is a torsion spring always better than extension? For most homeowners, yes. Torsion springs last longer and are safer. Extension springs cost less upfront but require earlier replacement. The total cost favors torsion over five to ten years.
What happens if my spring breaks while I'm away? You're locked out until replacement. Your door won't open, even with a manual release. Schedule service as soon as possible. We handle emergency calls during business hours and can often fit you in same-day.
