Torsion vs. Extension Springs: Cost and Lifespan Compared
Torsion springs cost more upfront (typically $200-$350 installed for a single spring, or $250-$450 for a pair) but last far longer, usually 15,000-20,000 cycles, or roughly 7-12 years of normal use. Extension springs are cheaper to install ($150-$250 for a pair) but wear out faster, around 10,000 cycles or 5-7 years. For most homeowners, torsion springs are the better long-term value because they last nearly twice as long, run smoother, and are safer when they break.
Step by step
-
1
Figure out which springs you already have
Look above and behind the door. A torsion spring sits on a metal shaft mounted on the wall just above the door opening, parallel to the top of the door. Extension springs run along the horizontal tracks on either side, stretching and contracting as the door moves. Knowing what you have tells you what a like-for-like replacement costs and whether an upgrade is even possible.

Compare the real cost over time, not just the sticker price
An extension spring pair might run $150-$250 installed versus $250-$450 for torsion. But torsion lasts roughly twice as long, so over 15 years you'll often replace extension springs two or three times. Add up those repeat service calls (each with its own trip and labor charge) and torsion usually comes out cheaper in the long run, plus you deal with fewer breakdowns.

Weigh lifespan in cycles, not just years
Springs are rated in cycles (one open and one close equals one cycle), not calendar years. Standard torsion springs are rated around 10,000 cycles, but high-cycle versions run 15,000-20,000+. Extension springs typically hit 10,000. If your family opens the door 6-8 times a day, that's about 2,500-3,000 cycles a year, so a 10,000-cycle spring lasts roughly 3-4 years of heavy use and a high-cycle torsion can last well over a decade.

Factor in safety and how the door performs
When an extension spring snaps, the loose spring and cable can whip across the garage, which is why they need a safety containment cable threaded through them. Torsion springs are contained on the shaft and fail more safely. Torsion also balances heavy and wide doors better, opens more smoothly, and puts less strain on your opener, which can extend the opener's life too.

5
Decide whether to upgrade or replace like-for-like
If you have extension springs and want fewer headaches, ask about converting to a torsion system. A conversion costs more (often $300-$500+ because of the new shaft, drums, and hardware) but pays off on heavy doors and high-use garages. If your extension setup is working fine and budget is tight, a straight replacement is perfectly reasonable. Always replace springs in pairs so they wear evenly.

6
Get an itemized quote and confirm the cycle rating
A fair spring quote lists the spring type, the cycle rating, parts, labor, and the trip/service fee separately. Ask specifically what cycle rating you're getting, because two quotes can look similar while one uses a 10,000-cycle spring and the other a 20,000-cycle spring that lasts twice as long. Reputable shops also typically warranty the springs and labor, so ask how long you're covered.
When to call a pro
Call a pro the moment a spring breaks or your door won't open, since garage door springs are under extreme tension and can cause serious injury if you try to adjust or replace them yourself; if you hear a loud bang from the garage, see a visible gap in the spring, or the door feels suddenly very heavy, stop using it and get a technician out same day.

Which lasts longer, torsion or extension springs?
Torsion springs last longer. Standard torsion springs are rated around 10,000 cycles and high-cycle versions reach 15,000-20,000+, while extension springs typically top out near 10,000 cycles. In real-world terms, that's roughly 7-12 years for torsion versus 5-7 years for extension at average use.
Are torsion springs worth the extra cost?
For most homeowners, yes. They cost more upfront but last about twice as long, so you replace them less often and spend less over the life of the door. They also run smoother, are safer when they fail, and put less strain on your opener, especially on heavy or wide doors.
Can I replace a garage door spring myself to save money?
We strongly recommend against it. Both spring types are under enormous tension, and a slip while winding a torsion spring or releasing an extension spring can cause severe injury. The savings on a $50-$80 spring aren't worth an ER visit, and a pro does the job in under an hour with the right winding bars and safety gear.
Why do garage door springs need to be replaced in pairs?
If you have two springs and one breaks, the other is usually close to the end of its life since both wore at the same rate. Replacing just one means you'll likely be paying for another service call within months. Doing both at once saves a second trip charge and keeps the door balanced.
