If you've ever had a garage door suddenly refuse to budge, you know the panic that follows. Most homeowners in Inglewood don't realize they have two completely different types of garage door springs, and confusing them during a repair can be dangerous and expensive. Understanding which spring system you have right now could save you hundreds of dollars and keep you safe.
Your garage door is held up by either torsion springs or extension springs. These aren't interchangeable parts. They work on completely different mechanical principles, fail differently, and require different replacement approaches.
Torsion springs sit horizontally above your garage door opening, mounted on a metal shaft. They twist and untwist as your door opens and closes, storing and releasing energy in a coiled motion. These springs are high-tension and under extreme pressure. A single torsion spring typically lasts 7 to 9 years with average use (opening and closing 3 to 5 times daily).
Extension springs run vertically along both sides of your door opening. They stretch and contract like actual springs as the door moves up and down. They're gentler than torsion springs but wear out faster because of the repetitive stretching motion. Extension springs usually last 5 to 7 years before showing signs of fatigue.
Here's where I need to be direct: a snapped spring is one of the most dangerous garage door failures I've encountered in my years serving Inglewood and surrounding areas. I've seen garage doors crash down because someone tried to jury-rig a broken extension spring or attempted a DIY torsion spring replacement.
Torsion springs are especially risky. The tension in that coiled metal is equivalent to a loaded crossbow. If a spring snaps while you're nearby, you could suffer serious injury. I've seen cuts, broken fingers, and head trauma from spring failures. This is not a DIY situation.
Extension springs are slightly safer to observe but equally important to handle professionally. When one snaps, the other side often fails within months because it's now carrying double the load. Many homeowners call us after one spring breaks, only to have the second one fail a week later. That's preventable with proper replacement of both springs at once.

Walk into your garage and look directly above the center of your closed garage door. If you see a single metal rod running horizontally across the top with coiled springs wrapped around it, you have a torsion system. The springs look like tight coils, and they're usually painted red or blue.
If you see two springs running along the left and right tracks, stretching vertically as your door opens, those are extension springs. They're typically longer and thinner than torsion springs, and they often have a safety cable running through the center of each one.
The safety cable on extension springs is critical. That cable stops the spring if it snaps, preventing it from flying across your garage. If you see a snapped spring without a cable or with a broken cable, you're looking at a serious hazard.
A snapped torsion spring usually announces itself loudly. You'll hear a sharp metallic bang, and your garage door opener will grind or stall. Don't force it up. A snapped extension spring is quieter but just as serious. Your door might close unevenly or slowly, or it might refuse to open at all.

The cost difference between torsion and extension spring replacement varies based on your specific setup, but both require professional diagnosis. We've detailed real pricing for Inglewood homeowners in our spring repair cost guide, which breaks down exactly what affects your estimate.
Don't wait for a spring to snap. If your door is moving unevenly, slower than normal, or making new sounds, schedule a free quote today. A professional inspection identifies worn springs before they fail, and we can often replace both springs during a single visit.
For Inglewood residents, same-day spring replacement is available for most calls placed before noon. Whether you need torsion or extension spring work, our technicians arrive equipped for both systems. We'll identify your spring type, assess the overall condition of your door, and give you an honest estimate before any work begins.
Don't gamble with a snapped spring. The cost of preventive replacement is far lower than emergency service, and your safety is worth every penny.
Q: Can I replace just one spring if the other is still working? A: We don't recommend it. If one spring has failed, the other is under extra stress and usually fails within weeks. Replacing both springs together prevents a second emergency call and keeps your door balanced.
Q: How much does a garage door spring replacement cost in Inglewood? A: Torsion spring replacement typically runs $200 to $400 per spring, while extension springs cost $150 to $300 each. Visit our services page for a detailed breakdown and to schedule your estimate.
Q: Is it ever safe to DIY a garage door spring replacement? A: No. Torsion springs especially are under dangerous tension. Extension springs can snap unpredictably. Professional replacement ensures proper installation, safety cables, and your door functioning smoothly for years.
Q: How long do garage door springs actually last? A: Torsion springs last 7 to 9 years with regular use. Extension springs last 5 to 7 years. Regular lubrication and maintenance can extend their lifespan slightly.
Q: What's the difference between a snapped spring and a worn spring? A: A snapped spring breaks completely and stops working immediately. A worn spring still functions but moves slower, makes noise, and is close to failure. Both require professional attention, though worn springs give you time to schedule service.
