If you've ever had a garage door stop working mid-morning, you know the panic sets in fast. Most often, the culprit is a snapped or worn spring. The question most homeowners ask isn't just "How do I fix it?" but "How much will this cost me?" The answer depends on which type of spring your door uses: extension or torsion. Understanding the difference now saves you hundreds down the road.
Your garage door weighs between 300 and 500 pounds. Something has to lift it safely, over and over again for 10,000 to 15,000 cycles over its lifespan. That's where springs come in.
Extension springs run along the sides of your garage door opening. They stretch and contract to provide lifting force. Torsion springs, by contrast, sit above the door and twist (torque) to store and release energy. Both do the job, but they behave very differently when something goes wrong.
Extension springs are simpler mechanically. They're cheaper to buy and cheaper to install. A typical extension spring replacement in Bedford runs between $150 and $250 per spring, often less. If one snaps, the other usually follows within months, so you'll replace both.
Torsion springs cost more upfront. Expect $200 to $400 per spring, plus higher labor. But here's the catch: they last longer. A quality torsion spring delivers 10,000 to 15,000 cycles. Extension springs manage around 7,000 to 9,000 cycles before fatigue sets in. Over a decade, torsion becomes the smarter investment even though the initial estimate looks steeper.
Let's do the math. If your door cycles 5 times daily, you're looking at roughly 1,825 cycles per year. An extension spring lasts 7,000 to 9,000 cycles, so you're replacing it every 4 to 5 years. Torsion springs last 10,000 to 15,000 cycles, pushing replacements to 7 to 8 years apart.
Over 20 years, extension spring owners typically replace springs 4 to 5 times. Torsion spring owners do it 2 to 3 times. Even though each torsion replacement costs $100 to $200 more per spring, the total cost is lower. Plus, torsion springs rarely fail suddenly. Extension springs snap without warning, leaving you stranded and forcing you into emergency service calls. That's where the real overspending happens.
Another factor: safety. Torsion springs are mounted above the door with heavy-duty cables and brackets. If they fail, the door doesn't drop suddenly. Extension springs, if they snap, can send that weight crashing down in a split second. The danger alone makes torsion worth the extra upfront cost.

Stand in your garage and look above your door. If you see a horizontal spring twisting back and forth when the door moves, you have torsion. If you see springs running along the left and right sides of the opening, you have extension.
Don't try to replace springs yourself. Seriously. They're under extreme tension. A slip means broken bones or worse. Professional replacement takes an hour and includes balance testing to ensure the door moves smoothly without the opener doing extra work.
For same-day or next-day service in Bedford and nearby towns, contact us for a free estimate tailored to your exact setup. We'll tell you whether repair makes sense or replacement is the smarter move. Our technicians inspect wear patterns and cycles, not just the obvious break.
If you're unsure whether your springs are nearing the end of their life, our guide on when to replace versus repair springs walks through the warning signs. Some doors benefit from a refresh in spring maintenance before a catastrophic failure. Others are ready to go right now.
We also offer a detailed look at common failure patterns and real replacement costs so you know what to expect before picking up the phone.
The cheapest option today isn't always the cheapest option next year. Extension springs cost less upfront but fail more often. Torsion springs cost more per replacement but stretch your time between repairs and keep your family safer.
If your door is more than 7 years old and uses extension springs, start thinking about a torsion upgrade during your next replacement cycle. It's a smarter investment. If you have torsion springs now, enjoy the peace of mind. You won't be climbing into emergency mode anytime soon.

How long do garage door springs typically last? Extension springs last 7,000 to 9,000 cycles (roughly 4 to 5 years with average use). Torsion springs reach 10,000 to 15,000 cycles (7 to 8 years). Lifespan depends on door weight, usage frequency, and maintenance.
Can I replace just one spring instead of both? No. If one spring snaps, the other is fatigued and will fail soon after. Always replace both at the same time to avoid a second service call and additional downtime within weeks.
Why is torsion spring replacement more expensive than extension? Torsion springs require specialized tools, precision balancing, and more complex installation above the door. Extension springs are simpler mechanically and take less labor time, making them cheaper to install despite shorter lifespan.
What happens if a garage door spring breaks while the door is open? The door won't fall if it's already open (the springs provide lift, not support). However, you won't be able to close it safely without a professional. Call for emergency service rather than forcing it.
Should I upgrade my extension springs to torsion? Yes, if your door is due for spring replacement anyway. The higher upfront cost pays back through fewer replacements and longer intervals between service calls over 10 to 15 years.
