Here's what most homeowners don't realize about garage door springs: they're doing 99% of the heavy lifting every time your door opens or closes. That 300-pound door isn't being lifted by your opener. Springs are. And when one fails, you're stuck with a door that won't budge and a repair bill you didn't budget for. After 15 years on the trucks here in Rancho Palos Verdes, I've seen springs fail at the worst possible times, and I've also seen homeowners try to fix them alone. Don't be that person.
Your garage door uses one of two spring types: torsion or extension. Torsion springs sit above the door opening, wound tight like a clock spring. Extension springs run along the sides of the door track. Both do the same job. Both store and release energy. Both are under serious tension.
The difference matters because it affects how they fail, what they cost, and how dangerous they are to replace. Torsion springs are the industry standard for newer homes and heavier doors. Extension springs are older technology but still common in older Rancho Palos Verdes properties.
Why does this matter to you? Because when a torsion spring snaps, the entire load transfers instantly to your opener and cables. Your door becomes a 300-pound dead weight. An extension spring failure is slightly less catastrophic, but the spring itself becomes a whipping hazard that can cause serious injury.
Springs last 7 to 9 years under normal conditions. That's roughly 10,000 to 15,000 cycles (one cycle = open and close). If you're opening and closing your door twice a day, you're looking at 10 to 12 years before replacement. Some people stretch it to 15 years. Don't count on it.
The coastal climate here in Rancho Palos Verdes actually puts extra stress on springs. Salt air and humidity corrode the metal faster than inland areas. You might see spring failure sooner than homeowners 30 miles inland. Regular maintenance catches wear before catastrophic failure.

A snapped spring is unmistakable. The door won't open at all, or it opens halfway and stops hard. You'll hear a loud bang when it breaks, usually sounding like a gunshot. If that happened, your door is not safe to use.
Other warnings come earlier. If your door is closing faster than normal or feels heavier when you open it manually, one spring is weakening. If you hear creaking or grinding noises that weren't there before, springs are losing tension. These are your opportunities to replace springs before they snap completely.

I'm going to be direct: replacing garage door springs is not a homeowner job. Springs are under 200 to 400 pounds of tension depending on door weight. When one breaks under that load, it can cause serious injury or death. Hospital records from spring accidents are ugly.
You need a spring replacement estimate from a professional. We'll inspect both springs even if only one is visibly broken, because the other is usually close behind. Our technicians use specialized tools and safety equipment.
The cost varies based on spring type and door weight. For a detailed breakdown, see our post on garage door repair costs and estimates in Rancho Palos Verdes. Most spring replacements in this area run between $200 and $400 per spring, sometimes higher for specialty doors.

A snapped spring needs immediate attention. If your door is stuck closed and you use it daily, same-day service matters. If it's stuck open and you have a secure garage, you have a few days to schedule.
If springs are weakening but not broken, you can schedule a routine appointment. You're not in emergency mode, but you should act within two weeks. Springs fail without warning once they start declining.

How do I know if my garage door spring is broken? The door won't open or closes much faster than normal. You may hear a loud bang when it breaks. The door feels extremely heavy when you try to open it manually. Never force a stuck door.
Can I replace just one spring? Technically yes, but we always recommend replacing both. If one spring has failed, the other is near the end of its life. Replacing both prevents a second failure soon after.
How long does spring replacement take? Most replacements take 1 to 2 hours from arrival to completion. We'll give you a time estimate when we arrive.
What's the difference between torsion and extension springs? Torsion springs sit above the door and wind like a clock. Extension springs run along the sides. Torsion is safer, more durable, and more common in newer homes.
Why are garage door springs so expensive? They're under extreme tension and require professional installation tools and expertise. DIY attempts cause injuries and death. Professional replacement includes safety equipment, warranty, and liability protection.
