It usually announces itself with a loud bang. like something fell in the garage. You walk out and find nothing on the floor. Then you hit the button and the door groans, barely lifts an inch, and stops. That's a broken garage door spring, and it's one of the most common repair calls we get from homeowners across Rancho Palos Verdes.
This post is a straightforward explanation of what springs do, how long they last, what replacement actually costs, and why this is one job you should never attempt yourself.
Your garage door. whether it's a single-car or the wide double door on one of the larger homes along Palos Verdes Drive East. weighs somewhere between 150 and 400 pounds. Your opener motor alone cannot lift that. The springs do the real work.
There are two types used in residential doors:
- Torsion springs are mounted horizontally above the door on a metal shaft. They wind and unwind to counterbalance the door's weight. They're stronger, last longer, and are the standard on most newer homes in RPV. - Extension springs run along the horizontal tracks on each side of the door. They stretch and contract to assist the lift. They're found on older doors and are generally less durable.
Torsion springs typically last between 10,000 and 20,000 cycles, which translates to roughly 7 to 15 years of normal use for most families. Extension springs have a shorter lifespan. around 5,000 to 10,000 cycles, or 7 to 12 years. Keep in mind that if your household opens and closes the garage four or five times a day. which is common in a busy RPV home with a long driveway and attached garage. you'll burn through those cycles faster than the averages suggest.
This is something specific to homeowners here on the peninsula, and in neighboring Torrance and Palos Verdes Estates as well. The salt air that drifts in off the Pacific accelerates oxidation on spring coils. A spring that might last 12 years in an inland home can show significant rust and metal fatigue in 8 to 9 years in a coastal environment. Regular lubrication with a silicone-based spray slows this process considerably. which is one reason the routine maintenance tasks that feel optional really aren't here.
Here's an honest breakdown. no lowball figures, no bait-and-switch framing.
For a standard residential torsion spring replacement, expect to pay $150 to $350 for a single spring including parts and labor, or roughly $200 to $400 for the full system (both springs plus the bar). Extension springs run $50 to $100 per spring with labor.
A few important points on cost:
- Replace both springs at the same time. Most garage doors use two springs. When one breaks, the other has experienced the same wear. Replacing only the broken one means the second often fails within months. Replacing both at once saves money and a repeat service call. - Higher-cycle springs cost more upfront but last significantly longer. For a coastal home where corrosion is a factor, paying more for premium springs is almost always worth it. - If your cables or rollers are worn, bundle the repairs. Cables and rollers are often installed alongside springs and wear at a similar rate. Combining repairs in one visit is more cost-effective than scheduling separate calls.

This is not a liability disclaimer. it's genuinely important. Torsion springs are under extreme mechanical tension. A spring under full load stores enough energy to cause serious injury or death if it releases suddenly. Professional technicians use specialized winding bars and follow exact procedures to control that tension during removal and installation.
DIY spring replacement kits exist, but the risks are significant: incorrect tensioning leads to premature spring failure, an unbalanced door that strains your opener, and in the worst cases, a door that drops unexpectedly.

Don't wait for the loud bang. Watch for these warning signs:
- The door opens slower than usual or feels heavier when lifted manually, You hear squeaking, grinding, or a high-pitched whine during operation, The door doesn't stay open on its own. it slowly lowers back down, You can see visible gaps or separation in the spring coil, One side of the door is lower than the other when it moves
If you spot any of these, the spring may not have failed yet but it's telling you something. Scheduling an inspection before full failure saves you from being stuck with a car in the garage and a door that won't move.
Garage Door Rancho Palos Verdes handles spring replacements across the peninsula. from the Miraleste Hills neighborhood all the way through the Eastview area. We stock both standard and high-cycle torsion springs so we can match the right spring to your door's weight and your usage pattern, not just install whatever's on the truck.
If your door has been sluggish, noisy, or just feels off, don't wait until it stops working entirely. Schedule a service call. most spring replacements take under an hour and we can usually assess the full system in the same visit.
Q: My garage door still opens but it sounds different and feels slow. Does that mean the spring is broken? A: Not necessarily broken, but likely weakening. A door that feels heavier or moves slower is often one with a spring that has lost tension or is beginning to rust and fatigue. This is actually the ideal time to call. a spring that's struggling can be replaced before it fails completely, which is safer and less disruptive than an emergency repair.
Q: Is it worth upgrading to torsion springs if my older door currently uses extension springs? A: For most RPV homeowners, yes. Torsion springs last longer, operate more smoothly, and are safer when they break because they stay contained on the shaft rather than flying loose. The conversion costs $400 to $800 but is a meaningful upgrade in both performance and safety. especially for a home where the garage is used daily.
Q: How do I know if my garage door opener was damaged when the spring broke? A: After a spring failure, a door operated by a struggling opener puts abnormal strain on the motor. Signs of opener damage include unusual grinding sounds, the door reversing mid-travel, or the motor running but the door not moving. A full inspection after any spring failure should always include a check of the opener. reach out to us and we'll assess both in a single visit.
