Garage Door Spring Types in Sunnyvale: Torsion vs. Extension (Which Costs Less?)
2026-08-01 7 min read A2Z Garage Doors
Most homeowners don't think about garage door springs until one snaps without warning. When that happens, you're stuck with a door that won't open and a decision to make fast. Understanding the two main types of garage door springs in Sunnyvale can save you hundreds of dollars and help you avoid rushed, expensive repairs.
What Are the Two Main Spring Types?
Garage doors rely on either torsion springs or extension springs to lift and lower the door safely. These aren't interchangeable parts, so knowing which one you have matters before you call for service.
Torsion springs run horizontally above your garage door opening. They twist and unwind to create lift. Most modern homes use torsion springs because they're more durable, safer, and last longer (typically 7 to 9 years with normal use). They also require less space and provide smoother operation.
Extension springs run vertically along both sides of the door frame. They stretch and contract to lift the door. Older homes often have extension springs, and they're generally cheaper upfront. However, they wear out faster (usually 5 to 7 years) and can be a safety hazard if they snap, since the door can fall suddenly.
Repair and Replacement Costs in Sunnyvale
Cost is the question that brings most homeowners to us. Here's what you're typically looking at in the Sunnyvale area.
Torsion spring replacement runs $200 to $400 per spring, depending on the door size and your contractor. If both springs need replacement (which is common), expect $400 to $800 total. Extension springs cost less to replace, usually $150 to $250 per spring, but you'll often need to replace both sides at once.
The real savings come from choosing torsion springs if you're installing a new door. Yes, they cost more upfront. But because they last 7 to 9 years versus 5 to 7 for extension springs, you'll spend less on repairs over a decade. One snapped spring means the whole door stops working, so a lifespan difference of 2 years adds up.

Which Spring Type Do You Have?
Look at your garage door from inside the garage. If you see a horizontal metal rod above the door with springs wrapped around it, you have torsion springs. If the springs run along the left and right sides of the frame and look like stretched coils, those are extension springs.

When to Repair vs. Replace
Springs don't always need full replacement. If one spring in a pair has failed, you have a choice. Repairing just the broken spring costs less immediately (usually $150 to $300), but replacing both springs at the same time costs more upfront and saves money long-term.
Here's the budget-conscious approach: if your springs are under 5 years old, repair the broken one. If they're older than 6 years, replace both. This prevents a second spring from failing two months later and costing you another service call.

DIY vs. Professional Service
Never attempt to replace garage door springs yourself. This isn't a beginner project. Springs are under extreme tension and can cause serious injury or death if mishandled. A professional technician has the tools, training, and insurance to do it safely.

If you hear creaking, squeaking, or see visible rust on your springs, call now. Small problems caught early cost far less to fix than a sudden failure that leaves you locked out.

Frequently Asked Questions
How long do garage door springs last? Torsion springs typically last 7 to 9 years with normal use (around 10,000 cycles). Extension springs last 5 to 7 years. Lifespan depends on usage frequency, maintenance, and climate conditions in your area.
Can I replace just one spring if both are old? Technically yes, but it's risky. If one spring fails, the other is likely near the end of its life too. Replacing both prevents a second failure weeks later and reduces total repair costs over time.
What does a snapped spring sound like? You'll hear a loud bang or crack, similar to a gunshot. The door will stop moving and feel heavy. Never try to open a door with a broken spring. Call a professional immediately for safety.
Are torsion springs safer than extension springs? Yes. Torsion springs are contained and safer if they fail. Extension springs can snap with more force and present a hazard. This is why modern codes favor torsion springs for residential doors.
How much does a garage door spring inspection cost? Many companies, including ours, offer free inspections and estimates. We'll identify the problem, explain your options, and quote the repair before you decide to move forward.
