Garage Door Spring Types in Culver City: Torsion vs. Extension Explained
2026-07-26 7 min read A2Z Garage Doors
Most garage doors in Culver City use one of two spring types: torsion or extension. Torsion springs sit above the door and twist to lift weight. Extension springs run along the sides and stretch to pull the door up. The type you have determines repair cost, lifespan, and replacement timing. We'll walk you through both so you understand what's actually needed.
Torsion Springs: The Stronger Choice
Torsion springs are the standard in modern garages. They're mounted horizontally on a shaft above the door opening. When the door closes, the springs wind up like a clock spring, storing mechanical energy. When you open it, that energy releases to counterbalance the door's weight, so your opener only needs to nudge it upward.
A few honest facts: torsion springs last 7 to 9 years with normal use. They handle weight distribution better than extension springs, which is why builders prefer them. If one snaps, the whole door becomes heavy and difficult to operate. You'll notice it immediately.
The cost for torsion spring replacement ranges from $250 to $500 per pair, depending on wire gauge and door weight. Thicker springs (heavier doors) cost more. This is not a DIY job. The tension is extreme, and a snapped spring can cause serious injury. If you suspect a broken torsion spring, schedule a free quote so we can assess it safely.
Extension Springs: The Budget Alternative
Extension springs are simpler. They hang from pulleys on each side of the door frame and stretch as the door lowers. When the door opens, they contract and help lift it. Older homes and lighter doors often use this design.
Extension springs wear out faster than torsion springs, typically lasting 5 to 7 years. They also require safety cables running through their center. If an extension spring breaks, the cable catches it and prevents it from whipping across your garage.
Replacement cost for extension springs runs $150 to $300 per pair. They're cheaper upfront, but the shorter lifespan means more frequent replacements over time. Most homeowners in Culver City are surprised to learn that a torsion upgrade actually saves money long term.

How to Tell Which Type You Have
Look above your garage door. If you see a thick metal shaft with coiled springs wound around it, you have torsion. If you see two springs hanging vertically along the sides with cables running through them, those are extension springs.

Signs Your Springs Need Replacement
A snapped spring is the obvious warning. But there are quieter clues. If your door opens unevenly, leans to one side, or feels heavier than usual, one spring may be failing while the other still holds. Read our guide on five warning signs your garage door spring needs replacement for a complete checklist.
Some homeowners ignore these hints and wait for a full break. That's when you get stuck with a door that won't budge and an expensive emergency call. Regular maintenance catches these issues early.
Cost Factors Beyond Spring Type
Spring replacement price depends on several variables. Door weight (single car vs. double car), spring quality, and your location within Culver City affect the estimate. A double car garage door needs heavier springs than a single car, so the springs themselves cost more.
Labor timing matters too. A same-day appointment may cost slightly more than a scheduled call three days out. We keep our pricing honest because we've built this business on repeat customers and referrals, not surprise bills. Check out our full breakdown of garage door repair estimate factors to understand what's included.
Prevention and Maintenance
Springs don't last forever. But you can extend their life. Lubricate the springs twice a year with a garage-door-rated lubricant. This reduces friction and wear. Keep the door balanced by testing it manually (disconnect the opener and lift it halfway). It should stay there.
If your door sags or drifts down slowly, springs are weakening. Our maintenance checklist for Culver City homeowners covers these checks in detail.
When a spring reaches 8 years old, start budgeting for replacement. Don't wait for failure. A proactive swap costs the same but avoids the stress of being locked out or stuck inside.

Frequently Asked Questions
How long do garage door springs last? Torsion springs last 7 to 9 years. Extension springs last 5 to 7 years. Lifespan depends on frequency of use, climate, and maintenance. A garage opened twice daily wears springs faster than one opened once daily.
Can I replace one spring instead of both? No. If one spring has failed, the other is close behind. Replacing both at once ensures balanced operation and prevents a second failure in weeks. It's more cost effective long term.
Is spring replacement a DIY project? Absolutely not. Spring tension can cause serious injury or death. The stored energy is equivalent to a small explosion. Professional technicians use specialized tools and training. Always hire a licensed expert.
Why is my garage door opening slowly? Weakening springs can't lift the door efficiently. The opener compensates by working harder, which slows the process. This is a sign both springs are nearing the end of their lifespan.
What's the difference in cost between torsion and extension? Extension springs are $150 to $300 per pair. Torsion springs are $250 to $500 per pair. Torsion costs more upfront but lasts 2 to 4 years longer, making it the better value over time.
