In our years serving Norwood, we've seen this problem again and again: homeowners don't know which type of garage door springs they have, leading to wrong repair decisions and unnecessary costs. Your springs are either torsion or extension springs, and mixing them up can drain your wallet fast. Here's how to identify yours and why it matters.
Your garage door weighs 300 to 500 pounds. Those springs do the heavy lifting, storing energy and making the door rise smoothly. Two main spring types handle this job, and they work completely differently.
Torsion springs twist like a clock spring. They're mounted horizontally above your door opening on a metal rod. When you open the door, they unwind and release energy upward. When you close it, they wind back up. Torsion springs last longer (7 to 9 years typically) and cost more upfront but provide better balance and quieter operation.
Extension springs stretch and contract like rubber bands. They hang vertically on both sides of your door, usually inside the tracks. As the door rises, they pull down; as it lowers, they release. Extension springs are cheaper initially but wear out faster (5 to 7 years) and create more noise and jerky movement.
Misidentifying your spring type leads to wrong repair quotes. A technician might quote you for torsion work when you actually need extension spring service, or vice versa. That confusion adds stress and delays. More importantly, springs under extreme tension can snap suddenly and cause injury.
If you have a snapped spring right now, don't attempt fixes yourself. Springs contain thousands of pounds of tension. A single slip costs lives. We've handled countless emergency calls from Norwood homeowners who tried DIY spring work. If you're curious about the risks involved, our guide on why DIY garage door spring repair is dangerous breaks down exactly what can go wrong.

Stand in your garage with the door closed. Look directly above the door frame, inside your garage. Do you see a tightly wound metal coil running horizontally across the top? That's a torsion spring. You'll typically see one large spring centered, sometimes with a smaller companion spring on either side.
See two springs hanging down the sides of your door frame, running vertically inside the tracks? Those are extension springs. They look like coils stretched out lengthwise.

Torsion spring replacement runs higher, typically 200 to 400 dollars depending on the spring's size and quality. Extension springs cost less upfront, around 150 to 300 dollars. But here's the catch: extension springs fail faster, so you'll replace them more often over your door's lifetime. Torsion springs represent better long-term value even though the initial cost stings.
Our detailed cost and pricing guide for Norwood homeowners explains what factors affect your repair estimate and how to avoid surprise charges.
Never replace springs yourself. We understand the temptation to save money. But spring replacement requires specialized tools, exact tension calculations, and years of experience. One mistake means a snapped spring, a damaged door, medical bills, or worse.

One broken torsion spring usually means you need to replace both springs at the same time, even if the second one works. They wear together, and replacing just one creates imbalance and faster failure of the remaining spring. This costs more upfront but prevents a second repair call within months.
Extension springs sometimes allow single-spring replacement, but we recommend replacing both for balance and consistency.
Call us at (980) 552-8250 for a honest assessment. We won't upsell you. If your springs have years left, we'll say so. If replacement makes sense, we'll explain why and provide a transparent estimate with no hidden fees.
Q: How long do garage door springs last? A: Torsion springs typically last 7 to 9 years; extension springs last 5 to 7 years. Life expectancy depends on usage frequency, maintenance, and climate conditions in your Norwood area.
Q: Can I replace just one spring? A: Torsion springs should be replaced in pairs for balance. Extension springs can sometimes be replaced individually, but we recommend replacing both for consistent performance and to avoid premature failure of the remaining spring.
Q: What does a snapped spring sound like? A: A loud bang or crack, often heard throughout the house. The door may drop suddenly or stop moving. Never attempt to operate the door after hearing this sound.
Q: How much does spring replacement cost in Norwood? A: Torsion spring replacement ranges from 200 to 400 dollars; extension springs cost 150 to 300 dollars. Final cost depends on spring size, door weight, and local labor rates.
Q: Is it safe to open my door if a spring is broken? A: No. A broken spring removes support from the door, making it fall quickly and unpredictably. This risks injury and door damage. Contact a professional immediately instead.
