A snapped garage door spring usually means your door won't open, and you're facing an unexpected repair bill. The two main spring types (torsion and extension) work differently, fail for different reasons, and cost different amounts to replace. Here's what Rancho Palos Verdes homeowners actually need to know.
Your garage door weighs 300 to 500 pounds. Springs counterbalance that weight, making the opener's job manageable. Without them, the motor would strain and fail fast. Springs last 7 to 9 years on average, depending on how often you use your door and whether you've kept up with basic maintenance.
Two types do this job: torsion springs and extension springs. Both can fail suddenly. Both are under extreme tension. Both require professional replacement.
Torsion springs sit horizontally above your door opening and twist to lift the weight. Extension springs hang vertically on each side and stretch. Most modern homes in Rancho Palos Verdes use torsion springs because they're more reliable and take up less space.
Torsion springs provide smooth, balanced lifting and last longer. They're safer because they're fully contained above the door. If one breaks, your door stays mostly balanced. Extension springs are cheaper to buy but less durable and carry more risk. If one snaps, the door can jerk dangerously to one side.
Most homeowners don't choose between them. The door's design dictates which type your home has. If you're curious about what your door uses, check the garage ceiling or call us for a free estimate.
Extension springs require safety cables to prevent the spring from flailing across your garage if it snaps. That's a hazard you want to avoid. Read our guide on garage door safety in Rancho Palos Verdes for more details on why this matters.
A single torsion spring replacement typically runs $200 to $400 in labor plus parts. Extension springs are cheaper, usually $150 to $300 in labor. But springs come in pairs, and if one is breaking, the other is probably next. Budget for both.
Total cost for a complete torsion spring replacement: $400 to $800. Extension springs: $300 to $600. These are ballpark figures. Your actual cost depends on your door size, spring type, and whether you're replacing one or both.
Don't confuse spring replacement with emergency service costs. If your door is broken at midnight on a Sunday, emergency rates apply. Our post on emergency garage door repair costs in Rancho Palos Verdes breaks down those premiums.

Springs are under 200 to 300 pounds of pressure. A slip means serious injury or death. Don't try this at home. This isn't being cautious. This is simple physics.
Signs you need spring replacement right now: your door won't open, opens unevenly, opens partway then closes, or makes a loud bang (that's usually a snapped spring). If you use your door every day and it's been 7 to 9 years since the last spring service, get an estimate for a tune-up and maintenance visit.
Professional technicians have the right tools, experience, and insurance. We'll inspect both springs, test the opener, and make sure your door runs smoothly after the job.
Get a written estimate before the work starts. Ask whether the price includes labor, parts, and a warranty on the new springs. Reputable shops like Garage Door Rancho Palos Verdes offer warranties of 3 to 5 years on parts.
If you've had recurring spring failures, the issue might be your door's balance or the opener itself. A full inspection catches those problems before you're back in the garage in another six months.

How long do garage door springs last? Most torsion and extension springs last 7 to 9 years with normal use (opening and closing 3 to 5 times daily). Heavy use shortens lifespan. Lack of maintenance speeds wear.
Can I replace just one spring? You can, but not recommended. If one is failing, the other is near the end of its life. Replacing both prevents another breakdown in months.
What's the difference between torsion and extension springs? Torsion springs twist above the door opening and provide balanced lift. Extension springs stretch on the sides and are less reliable and more hazardous if they snap.
Why is spring replacement expensive? Labor is high because the job is dangerous and requires specialized tools. Parts cost money too. But delaying replacement often costs more when the door gets stuck.
