Here's what most homeowners don't realize about garage door springs: not all springs are created equal. Your garage probably uses one of two types, and choosing the wrong replacement can cost you hundreds of dollars extra or leave you with a door that won't open safely.
The two main types are torsion springs and extension springs. Torsion springs sit horizontally above your garage door opening, while extension springs run vertically along the sides. Each works differently, costs differently, and fails differently. Understanding which one you have helps you avoid overspending when repairs become necessary.
Torsion springs are the more common and durable option in modern garages. They wind up like a clock spring and use torque to lift the door. When you press the opener button, the spring unwinds gradually, counterbalancing the door's weight so the motor does minimal work.
Torsion springs last 7 to 9 years with average use (around 10,000 cycles). They handle heavier doors better and distribute stress more evenly. If a torsion spring snaps, the door won't open at all, but the failure is usually sudden and obvious.
The trade-off: torsion springs cost more upfront. A replacement typically runs $200 to $400 per spring, plus labor. But because they last longer and rarely wear unevenly, you get better long-term value.
Extension springs hang on either side of the door and stretch as it opens. They're cheaper to buy (usually $50 to $150 per spring) and easier to install, which is why they appear on older or lighter-duty doors.
The catch: extension springs wear faster and fail unpredictably. They often break one at a time, meaning you might replace one spring only to have its partner snap weeks later. Safety cables run through them to catch a snapped spring before it whips dangerously, but that safety feature adds cost and complexity.
If you have extension springs and one breaks, learn about repair versus replacement costs to make a smarter decision.

Walk into your garage and look above the door. Do you see a tightly wound coil running horizontally across the center? That's a torsion spring. Do you see two springs running vertically on each side that look like they stretch? Those are extension springs.
Not sure? Take a photo and call us. Misidentifying your spring type wastes time and money.
A snapped spring isn't just about the part itself. Installation difficulty, safety considerations, and door weight all play a role. Torsion springs require precise torque calculations and special tools, so professional installation is non-negotiable. Extension springs are simpler to install but need safety cable inspection during the job.

Regular maintenance catches spring wear before catastrophic failure. A technician can test spring tension and spot corrosion or signs of fatigue. In Riverside's dry climate, springs corrode slower than in coastal areas, but dust and temperature swings still take a toll.
Follow our maintenance schedule to avoid costly repairs and extend spring life by years.
If your door feels heavier than usual, opens slowly, or makes grinding noises, springs are likely weakening. Don't wait for a complete failure. A same-day estimate from Garage Door Riverside costs nothing and gives you a clear picture of what's needed.

Spring failure is one of the most common garage door emergencies, but it's also one of the most preventable. Know your spring type now, and you'll never overpay for an emergency repair.
How long do garage door springs last? Torsion springs typically last 7 to 9 years with regular use (about 10,000 cycles). Extension springs wear faster, often lasting 5 to 7 years. Lifespan depends on door weight, frequency of use, and maintenance.
Can I replace just one spring if the other is fine? It's risky with extension springs because the second spring will likely fail soon after. With torsion springs, replacing both at the same time prevents imbalance and future callbacks. Ask your technician for a paired replacement quote.
What does a snapped spring sound like? A loud bang or crack, followed by the door refusing to open. The motor may hum but won't lift the door. Never force it. Call for emergency repair immediately.
Is torsion or extension cheaper to repair? Extension springs cost less initially but fail more often. Torsion springs cost more per replacement but last longer and require fewer total repairs over 10 years. Torsion wins on total cost of ownership.
Do I need to replace springs myself to save money? Spring replacement is dangerous without proper tools and knowledge. Improper tension can cause door failure or injury. Professional installation costs $200 to $400 in labor but guarantees safety and warranty protection.
