Let's cut through the confusion about garage door springs. These metal coils do nearly all the heavy lifting when your door opens and closes, and most homeowners have no idea how they work or what happens when one fails. After 15 years on service calls across Daly City and the Peninsula, I've learned that understanding your springs saves thousands in unexpected repair bills and keeps your family safe.
Your garage door weighs between 300 and 500 pounds. You don't feel that weight when you press the opener button because springs handle it. Two main types exist: torsion springs sit above your door on a metal rod and twist to lift the load, while extension springs run along the sides and stretch to do the same job. Torsion springs are far more common in modern homes and typically last 7 to 9 years with regular use.
The spring stores mechanical energy. When you open the door, the spring releases that energy, making the opener's job nearly effortless. When a spring snaps, your opener suddenly has to lift the full weight alone. Most residential openers can't handle it. That's why a snapped spring means your door won't open, or it opens partway and sticks.
A snapped spring is unmistakable: your door won't move, or it falls hard when opening. But earlier warning signs matter too. Listen for creaking or squeaking when the door operates. Watch for uneven movement, where one side rises faster than the other. If your door feels heavier than usual or the opener strains audibly, springs are wearing out.
Springs don't just fail suddenly. They weaken over months or years. That's why maintenance catches problems before they strand you in your driveway. If you've noticed any of these signs, our 7 warning signs your garage door needs professional repair post covers the full picture.
Torsion springs are safer and more reliable. They're enclosed above the door, so they can't snap and whip across your garage. Extension springs are cheaper upfront but sit exposed on each side. When one breaks, the loose spring becomes a projectile. I've seen them punch through drywall and shatter windshields. If you have extension springs, consider upgrading to torsion when replacement time comes.
Cost varies based on type and quality. A basic torsion spring replacement runs $200 to $400 per spring. Extension springs cost $150 to $300 each. Labor typically adds another $100 to $200. Most doors need two springs, so budget accordingly. For detailed pricing context, check our garage door cost and pricing guide for Daly City.
**Need garage door springs in Daly City today?** Call 650-753-7227. We cover same-day service across the area.
If one spring is broken and the other is 5 years old, replace both. Springs wear at similar rates, and replacing one while the other is weak means you'll call us back in a few months. That doubles your labor costs. Think of it like tires: you replace pairs, not singles.
If your door is over 20 years old and springs fail, consider whether the whole door needs replacement. Older doors often have outdated safety features and poor insulation. We've written about smart garage door technology and how upgrades improve security and convenience, but sometimes a new door with modern springs makes more sense than patching an aging system.
Springs are under extreme tension. Releasing that tension without proper tools and training can cause serious injury. Hospital visits, crushed fingers, and eye injuries happen when homeowners attempt DIY spring work. Professionals use specialized winding bars and safety cables. Let us handle it. Call 650-753-7227 to get a same-day estimate.
Regular lubrication with silicone spray keeps springs flexible and reduces wear. Inspect them monthly for rust, cracks, or uneven gaps between coils. Clean your garage to reduce dust buildup on the springs. These simple steps can add a year or two to your spring's lifespan, saving money over time.
If your door gets stuck or stops working, don't force it. That emergency situation deserves immediate attention. We've covered what to do in our emergency garage door service guide.

How long do garage door springs last? Torsion springs typically last 7 to 9 years under normal use, rated for 10,000 to 20,000 cycles. Extension springs wear faster, usually lasting 5 to 7 years. Frequency of use and climate affect lifespan significantly.
What does a snapped spring sound like? A loud bang or crash, like a gunshot. The door may fall suddenly, or the opener may struggle and stall. You'll hear metal hitting metal or concrete as tension releases violently.
Can I open my door manually if the spring is broken? Technically yes, but it's dangerous. Without the spring's assistance, you're lifting 300 to 500 pounds by hand. The door can slam shut and cause injury. Call a professional instead.
How much does spring replacement cost near me? Expect $200 to $400 per torsion spring plus $100 to $200 labor. Most doors need two springs, so budget $500 to $1,200 total. Extension springs run cheaper but require more frequent replacement.
Should I replace both springs if only one broke? Yes. Both springs age together. Replacing one while the other is weak means a second service call within months, doubling labor costs and inconvenience.
