A snapped garage door spring means your door won't open, and you're stuck at home or locked out of your garage. Garage door springs in Paramount typically cost between $150 and $400 per spring for parts and labor, depending on the type (torsion or extension) and your door's weight. Most springs last 7 to 9 years with normal use. If yours has failed, same-day replacement is usually possible.
Your garage door weighs 300 to 500 pounds. Springs counterbalance that weight so your opener can lift the door without straining. Without functioning springs, the door becomes a deadweight. You'll hear a loud bang or snap when a spring fails, often followed by a door that won't budge.
There are two main types: torsion springs sit above the door on a horizontal rod and twist to release energy, while extension springs run along the sides and stretch to assist the lift. Most modern homes in Paramount use torsion springs because they're safer and last longer. Extension springs can snap more suddenly and pose a safety hazard if they fail.
Springs don't just wear out from opening and closing. Heat cycles, salt air near the coast, and garage humidity all accelerate wear. A spring rated for 10,000 cycles (roughly 7 to 9 years of typical use) will fail faster if exposed to extreme temperature swings, which is common in Southern California.
If your door opens partway then stops, or if you hear a loud crack followed by the door not responding, springs are likely the culprit. You might also notice the door feels heavier than usual when you try to pull it up manually, or the opener struggles to lift it even though the motor sounds fine.
We've covered this in detail in our guide on 5 signs your garage door spring needs replacement. That post walks through visual inspections you can do from inside the garage to spot wear before a complete failure.

A single torsion spring replacement typically runs $200 to $350 including labor. If both springs need replacement (which we often recommend for balance), expect $400 to $650 total. Extension springs cost less per unit but labor is similar.
The estimate depends on your door's weight, the spring's quality grade, and whether you need same-day service. Emergency calls outside business hours add a trip charge. We always provide a free estimate before any work begins, no pressure.

If your door is stuck now, don't force it. Forcing a door with a broken spring risks damaging the opener or the door itself, adding cost to your repair. Let us handle it safely and affordably.
How long do garage door springs last? Most torsion springs last 7 to 9 years under normal use, rated for 10,000 to 15,000 cycles. Extension springs may fail sooner. Humidity and temperature swings in Paramount can reduce lifespan by 1 to 2 years.
Can I replace just one spring if both are old? Technically yes, but we recommend replacing both if they're similar age. Springs wear at the same rate, so the remaining old spring will likely fail within months. Replacing both ensures balanced operation.
What's the difference between torsion and extension springs? Torsion springs twist above the door and are safer, longer lasting, and more reliable. Extension springs stretch on the sides, cost less upfront, and can snap more suddenly. Most new installations use torsion.
Is spring replacement covered by my garage door warranty? Warranties vary. Springs typically carry a 1 to 2 year parts warranty from us. Full door warranties usually exclude springs after the first year. Check your paperwork or call us to confirm.
How do I know if both springs are broken? If your door won't open at all or opens only a few inches before stopping, both springs are likely failed or very weak. A single broken spring usually allows partial movement. We'll inspect and advise during a free estimate.
