Here's what most homeowners don't realize about garage door springs: not all springs work the same way. Your garage door uses either a torsion spring or an extension spring, and mixing them up or choosing the wrong replacement can cost you time, money, and safety. Understanding which type you have matters before you call for help.
Torsion springs sit horizontally above your garage door opening, mounted on a metal shaft. They work by twisting (or torquing) to store and release energy as your door moves up and down. When you open the door, the spring unwinds, counterbalancing the weight of the door itself. When you close it, the spring winds back up.
Torsion springs are engineered to handle heavy loads with precision. They're more durable than their counterparts, typically lasting 7 to 9 years with regular use. A single torsion spring can handle doors weighing 300 to 400 pounds. Most residential garage doors in Culver City use this design because it's safer, more reliable, and takes up less space than the alternative.
The trade-off? Torsion springs cost more upfront, and they require professional installation. Never attempt this yourself. The tension stored in these springs is genuinely dangerous, and improper handling has caused serious injuries.
Extension springs hang vertically on both sides of your garage door, typically above the horizontal track. Instead of twisting, they stretch and contract to provide lift. As your door opens, the springs extend. As it closes, they compress back to their resting length.
Extension springs are lighter and cheaper than torsion springs, which is why some older homes or budget installations use them. However, they don't last as long. You can expect 5 to 7 years of service before a snapped spring becomes likely. Because they work in tension, they're also more prone to sudden failure.
Most Culver City homeowners upgrade to torsion springs when their extension springs fail, simply for the added lifespan and safety margin.
Look above your garage door opening. If you see a metal shaft running horizontally across the top with a spring coiled around it, you have a torsion spring setup. If you see two springs running vertically along the sides of the door, one above each track, you're dealing with extension springs.

Spring replacement cost varies significantly based on type. Extension springs typically run $150 to $250 per spring, while torsion springs range from $200 to $350 each. Most doors have two extension springs or one torsion spring (though high-capacity doors may have two torsion springs).
The labor also differs. Extension spring replacement takes 1 to 2 hours. Torsion spring work takes longer and demands specialized tools. Both require a trained technician. Attempting DIY replacement with a snapped spring in your garage is how accidents happen.
If you're considering an upgrade from extension to torsion, the investment pays dividends over time. You'll reduce your total replacement frequency and gain peace of mind. For a detailed cost breakdown tailored to your specific door, schedule a free quote today.

A snapped spring won't always announce itself loudly. Sometimes you'll notice your door feels heavier when opening, or it won't stay up without the opener running. The door might creak, wobble, or move unevenly. These are all warnings that spring failure is imminent.
Never ignore a sagging door. A broken spring means your opener is working twice as hard, which shortens its lifespan and increases your electricity bill. Learn more about recognizing spring problems before they escalate.
The longer you wait, the more expensive the repair becomes. What starts as a simple spring replacement can turn into opener damage or track misalignment if you're not careful.

Torsion springs last 7 to 9 years. Extension springs typically last 5 to 7 years. Lifespan depends on cycle frequency, maintenance, and climate. Springs in Culver City's moderate climate generally perform at the longer end of these ranges.
No. Springs are engineered as a pair to balance your door evenly. Replacing only one causes uneven weight distribution, which strains your opener and tracks. Replace both springs at the same time, even if only one has snapped.
Extension springs cost $300 to $500 total (both springs plus labor). Torsion springs cost $400 to $700 total. Exact pricing depends on your door size, spring type, and whether additional repairs are needed. Call us for a free estimate.
Yes. A broken spring means your door is extremely heavy and dangerous to operate. Your opener may fail trying to lift the full weight. Do not attempt to open or close the door manually. Contact a professional immediately.
A snapped spring breaks suddenly, usually during operation. A worn-out spring weakens gradually over years until it eventually snaps. Both require replacement. Regular maintenance helps catch wear-out before sudden failure occurs.
