Torsion vs. Extension Springs in Monrovia: Which One Do You Have?
2026-06-20 7 min read
Your garage door springs are either torsion or extension type, and knowing which one matters before you call for help. Most Monrovia homes use torsion springs (the coiled metal bar above the door), but some older homes still have extension springs running along the sides. Mixing them up when describing a snapped spring to a technician wastes time and delays your repair.
Why Spring Type Matters for Your Wallet
Torsion and extension springs work completely differently, which affects repair cost, safety, and how fast you can get your door working again. Torsion springs store energy by twisting under tension, while extension springs work by stretching like a rubber band. If you describe the wrong type, you might get quoted for the wrong repair or wait for a technician who shows up unprepared.
Understanding your spring type also helps you spot problems early. A snapped extension spring is usually visible hanging loose along the side track. A broken torsion spring is harder to spot, but you'll notice the door feels heavier than normal or won't open smoothly. Catching either problem fast saves you from a stuck garage door situation when you need to leave for work.
Torsion Springs: The Heavy-Duty Standard
Torsion springs are mounted horizontally above your garage door opening on a metal shaft. They're the more common choice in modern homes because they last longer and handle repeated use better than extension springs. Most torsion springs last 7 to 9 years with average use, assuming you keep the door maintained.
These springs come in different wire gauges and lengths, which is why getting an accurate estimate requires a professional measurement. Torsion springs also distribute weight more evenly across the door system, which means less strain on your opener and tracks over time.

Extension Springs: Older, Simpler, Riskier
Extension springs run along both sides of the door on the upper tracks. They're cheaper upfront than torsion springs, which is why you'll find them on older homes and budget installations. However, they require safety cables that run through the center of each spring to catch the spring if it breaks.
Without those safety cables, a snapped extension spring can whip across your garage with dangerous force. This is why extension springs need more frequent inspection and maintenance. They also wear out faster, typically lasting 5 to 7 years instead of the 7 to 9 years you get from torsion springs. If you're running extension springs and haven't had them inspected recently, now is the time.

How to Identify Your Spring Type Right Now
Walk into your garage and look above the door. If you see a horizontal metal shaft with coils wrapped around it, you have a torsion spring. If you see springs attached to the door frame on the left and right sides that stretch toward the back, those are extension springs. Take a photo and send it to us, or describe what you see when you visit our services page to get accurate pricing.
Never touch the springs themselves. Both types are under extreme tension and can cause serious injury if they snap while you're near them. Even if you're handy with other home repairs, spring replacement should always be professional work.
Cost Differences and What Affects Your Quote
Torsion spring replacement typically costs more than extension spring replacement because of the specialized equipment needed and the precision required for installation. However, you'll recoup that difference through longer spring life and fewer repairs to other door components. Extension springs put more stress on your opener and tracks, which means you might face additional repairs down the road.
The exact cost depends on your spring size, your door weight, and local labor rates in Monrovia. For a detailed breakdown of what you'll actually pay, check out our article on garage door repair costs in Monrovia to see real numbers and avoid sticker shock.

Frequently Asked Questions
Can I replace just one spring if both are old? No. If one spring is near the end of its life, the other is too. Replacing springs in pairs ensures balanced door operation and prevents premature failure of the second spring. Both springs should be replaced together for safety and performance.
How do I know if my spring is about to break? Listen for creaking or squeaking from the springs, or notice the door opening slower than usual. The door may feel heavier or shake during operation. These are early warning signs that replacement is coming soon.
Is emergency spring replacement more expensive? Yes, emergency or same-day service typically costs 15 to 25 percent more than scheduled appointments. Scheduling regular maintenance helps you avoid emergency rates and keeps repair costs predictable.
What happens if a spring breaks while the door is closing? The door will stop or drop suddenly. This is why safety cables matter on extension springs. Modern torsion systems have built-in safeguards, but any broken spring requires immediate professional attention.
How often should springs be inspected? Annual inspection is ideal, especially if you use your garage door frequently. We recommend checking springs during seasonal maintenance or whenever you notice changes in door operation.
