Your garage door springs are doing heavy lifting every single day, and most homeowners don't think about them until one snaps. The two main types are torsion and extension springs. Torsion springs sit above the door and twist to lower and raise it. Extension springs run along the sides and stretch to do the same job. Both fail eventually, but knowing which one you have matters for cost, safety, and repair time.
Torsion springs are the workhorse. They're mounted horizontally on a shaft above your garage door opening. When you open the door, the spring winds up like a clock spring, storing energy. That stored energy does the real work of lifting the 300 to 400 pound door. When you close it, the spring unwinds slowly, controlling the descent. This design is smooth, durable, and safer for most residential setups in Santa Clarita. See our guide on garage door photo eye safety in santa clarita: why this one feature saves lives.
Extension springs hang on both sides of the door track. They stretch and contract like actual springs (think Slinky). They're less common in newer homes but still found in older installations throughout our area. They're cheaper upfront but require safety cables running through them. If an extension spring snaps without those cables, the spring whips across your garage at dangerous speeds.
Torsion springs typically last 7 to 9 years with normal use. Extension springs often wear out faster, especially in our hot, dry Santa Clarita climate where UV exposure degrades the metal coils. Read about garage door maintenance in santa clarita: the tune-up that stops costly repairs.
Springs don't just snap out of nowhere. Wear and tear is gradual. Every time your door opens and closes, the spring cycles. Most residential springs handle 10,000 to 15,000 cycles before failure. That's about 5 to 7 years for a household that opens and closes once or twice daily.
Heat accelerates wear. Our summers in Santa Clarita push temperatures well over 100 degrees. Metal expands and contracts, metal fatigues. Rust and corrosion also weaken springs, especially if your garage lacks proper ventilation. Poor maintenance (no lubrication) speeds up failure too.
A snapped spring is obvious: your door either won't open, or it opens partway then crashes down. Never force a door with a broken spring. You risk serious injury or damage to the opener itself. If you suspect a snapped spring, stop using the door and call a professional right away.

A torsion spring replacement typically costs $150 to $300 per spring, depending on the quality and size. Extension springs run $100 to $200 per pair. Those prices are for the parts and labor combined when you work with a licensed tech. If you need both springs replaced (common, since they age together), budget accordingly.

The good news: we offer same-day service for broken springs. Most jobs take 1 to 2 hours. We'll assess your current setup, give you a free estimate, and get your door working safely again. Spring replacement isn't a DIY job. The tension in a torsion spring is extreme and dangerous. Even experienced homeowners have been seriously injured trying to replace springs alone.
Regular garage door maintenance catches worn springs early. During a tune-up, we inspect spring tension, listen for creaking, and check for rust or corrosion. Catching wear before a snap saves you money and prevents being stuck with a non-functional door.
When one spring fails, the other is usually not far behind. We almost always recommend replacing both at the same time. It costs a bit more upfront but prevents a second service call in a few months. Your door also operates more evenly when both springs are fresh.
After spring replacement, your door should open and close smoothly. If it's still jerky, sluggish, or uneven, the opener or tracks may need attention. Visit our full services page to see what else we can check while we're out.
Don't ignore a broken spring hoping it'll fix itself. The longer your door sits unused, the more stress builds on your opener and tracks. Get it handled quickly. Schedule a free quote or call us at 661-765-8128 to book a same-day visit.
How long do garage door springs last? Torsion springs typically last 7 to 9 years under normal use. Extension springs often fail sooner, especially in hot climates like Santa Clarita. Lifespan depends on cycle count, maintenance, and local weather.
Can I replace a garage door spring myself? No. Spring tension is extremely dangerous and can cause serious injury or death. Professional technicians use specialized tools and training. Always hire a licensed repair company for spring work.
What's the difference between torsion and extension springs? Torsion springs twist above the door and are safer, more durable, and smoother. Extension springs stretch on the sides and are cheaper but require safety cables. Torsion is standard in modern homes.
Why did my spring break without warning? Springs wear gradually with each cycle. You may not notice signs until failure. Regular maintenance catches wear early. Heat, rust, and poor lubrication all accelerate failure.
How much does spring replacement cost in Santa Clarita? Torsion springs run $150 to $300 per spring. Extension springs cost $100 to $200 per pair. Labor is included. Most jobs take 1 to 2 hours and qualify for same-day service.
