In our 15 years serving San Marcos homeowners, we've seen this problem again and again: a garage door that won't budge, and the culprit is always the springs. The question isn't whether springs fail, it's whether yours can be fixed or needs full replacement. Most of the time, a snapped spring means replacement, not repair, and understanding the difference saves you money and headaches.
Garage door springs come in two types. Torsion springs sit above the door and twist to lift the weight. Extension springs run along the sides and stretch to assist. Both wear out, but how they fail shapes your repair decision.
A snapped torsion spring often signals the end of the road. These springs handle enormous tension (up to 10,000 pounds of force), and when metal fatigues and breaks, welding or patching isn't reliable. A broken extension spring sometimes allows repair, but replacement is still safer and more durable. Springs last 7 to 9 years on average, depending on how many cycles your door goes through.
Here's what techs know that homeowners don't: springs are engineered to fail together. If one torsion spring snaps, its twin isn't far behind. Replacing just the broken one leaves you with a mismatched pair, causing uneven door movement and premature opener strain. You'll be calling us back in weeks.
Full replacement means both springs come out and new ones go in, balanced and synchronized. It costs more upfront but prevents repeat failures and keeps your door operating safely. Our team at Garage Door San Marcos always recommends replacing both springs at the same time, even if only one looks damaged.

Torsion spring replacement typically runs $200 to $400 per spring, plus labor. Extension springs are cheaper, $100 to $150 each. If both need replacing, budget $400 to $600 total, depending on door size and spring quality. That's honest pricing, not the inflated estimates some shops push.
If you're trying to figure out whether to repair or replace, get a free estimate first. We'll inspect the springs and tell you straight whether your door can limp along or needs new ones. You can read our full breakdown on garage door repair costs in San Marcos to understand the bigger picture.
Repair makes sense in only a few scenarios. If a spring shows surface rust or minor corrosion but no cracks or breaks, cleaning and lubricating can extend its life. If bolts are loose or hardware is misaligned, tightening everything costs almost nothing and buys you more time.
But if you hear a loud bang from the garage and the door won't open, that's a snapped spring. A crash followed by a dead door means replacement is your only option. Don't waste money on a repair attempt; go straight to replacement.
Spring problems don't wait. A broken spring leaves your door stuck, blocking your car and compromising security. That's why we offer same-day estimates and service across San Marcos and surrounding areas. Most spring replacements take 1 to 2 hours, so you're back to normal the same day you call.
If your door is already stuck, don't try to open it manually. That puts you at risk of injury. Instead, schedule a free quote with us and we'll get you sorted fast.
The best way to avoid spring failure is maintenance. Springs need periodic lubrication and inspection. A professional tune-up catches wear early and extends spring life by years. If you haven't had your door serviced recently, now's the time. We've published a detailed guide to garage door maintenance that prevents costly repairs before they start.
Spring failure is expensive and disruptive, but it's also predictable and preventable. Whether you need repair or replacement, the answer depends on how the spring failed and how long ago it was installed. When in doubt, call a pro. We'll give you an honest answer and get your door working again.

Can you repair a snapped garage door spring? No. A completely snapped spring must be replaced, not repaired. Welding or splicing a broken spring is unsafe and won't handle the tension properly. Replacement is the only reliable solution for snapped springs.
How long does it take to replace garage door springs? Most torsion and extension spring replacements take 1 to 2 hours. We typically complete the job the same day you schedule service. Same-day availability depends on current workload in San Marcos.
Should I replace both springs if only one is broken? Yes. Springs wear together, and replacing just one leaves you with an imbalanced pair. The surviving spring will fail soon after. Always replace both springs at the same time for safety and durability.
What causes garage door springs to fail? Springs fail due to age, rust, repetitive stress, and lack of lubrication. Most springs last 7 to 9 years. Harsh weather and heavy use accelerate wear. Regular maintenance can extend their lifespan.
Is spring replacement covered by my garage door warranty? Most manufacturer warranties cover springs for 3 to 5 years. After that, replacement costs come out of pocket. Check your door's documentation or call us for warranty details specific to your model.
