A customer called last Tuesday with a garage door that wouldn't open. His torsion spring had snapped that morning. He'd already called two other shops and was quoted $400 to $600 for the repair. When I gave him our estimate of $285 for the same job, he asked what the catch was. There is no catch. He got honest pricing, same-day service, and a two-year warranty on parts. That's how we operate at Garage Door Cupertino.
Your garage door weighs 300 to 500 pounds. Two springs do nearly all the heavy lifting. Over time, metal fatigue sets in. Most torsion and extension springs last between 7 and 9 years, depending on how often you open and close the door. A household that uses their garage door 4 to 8 times daily will wear springs out faster than someone who uses it once or twice.
The moment a spring snaps, your door becomes a dead weight. The opener can't lift it. You're stuck.
Springs fail for predictable reasons: rust from humidity, poor maintenance, manufacturing defects, or simply age. Here in Cupertino and surrounding areas, salt air and temperature swings accelerate corrosion. If you haven't had your springs inspected in three years, they're due.
Extension springs run horizontally above your door on both sides. They stretch and contract as the door moves. Torsion springs sit on a rod above the door and twist. Torsion springs are stronger, safer, and last longer. They're also more expensive to replace (usually $200 to $350 per spring), while extension springs run $150 to $250 each.
Most modern garages use torsion systems because they're more reliable. If you're unsure which you have, don't attempt a DIY fix. A snapped spring under tension can cause serious injury. This isn't a weekend project.

Let's be transparent about pricing. A single torsion spring replacement runs $250 to $350, including labor and the spring itself. If both springs are old, replacing them together costs $450 to $650. Add a service call fee of $65 to $85 if it's after hours or on weekends.
The reason costs spike for emergency repairs comes down to availability and urgency. If your door fails on a Sunday afternoon, you're paying a premium. That's standard across the industry. Our philosophy is to keep regular pricing fair so you're not shocked when the bill arrives. We charge what the job actually costs, plus a reasonable margin.

Don't wait for a snap. Watch for these warning signs: your door opens unevenly, one side rises faster than the other, you hear a loud bang or twang, or the door feels heavier than usual when opening. Any of these means a spring is failing and needs attention within days, not weeks.
If you've had the same door for 8 years or longer, have the springs inspected this month. A quick inspection costs nothing and can prevent a stuck door at the worst possible time. Schedule a free quote with us at /contact and we'll assess the condition of your springs while we're there.
Another common issue is poor maintenance. If your springs show surface rust or haven't been lubricated in over a year, they're working harder than they should. Our garage door maintenance guide covers what you can do between professional visits to extend spring life.
Here's the honest truth: do not replace garage door springs yourself. The risk of injury is too high. A compressed spring can release suddenly and cause broken bones, lacerations, or worse. Even experienced mechanics use specialized tools and follow strict safety protocols.
What you can do is keep springs clean, lubricate them lightly with silicone spray twice a year, and watch for rust. Leave the replacement work to trained technicians. Our team at Garage Door Cupertino has the right equipment, insurance, and experience to handle it safely and fast.
If you're also dealing with opener issues or considering a full door replacement, we've written about which garage door openers work best and when it's time to replace your garage door entirely.
A snapped spring is an emergency. You can't use your garage, and the longer you wait, the more risk of secondary damage to the door panels or opener. Call us right now at (669) 322-7483. If it's during business hours, we'll get you a same-day estimate and often can complete the repair the same afternoon.
We serve Cupertino and all of the surrounding Silicon Valley communities. No hidden fees. No pressure to replace parts you don't need. Just honest service and fair pricing.
How long does it take to replace a garage door spring? A single spring replacement takes 45 minutes to 90 minutes, including inspection and testing. Both springs take about 2 hours. Most of our same-day appointments are completed before dinner time.
Can I open my garage door if the spring is broken? No. A broken spring removes the counterbalance. The opener can't lift the door safely. Forcing it risks damage to the opener motor and door panels. Call a professional instead.
Do both springs need replacing at the same time? Not always, but we recommend it. If one spring has failed, the other is likely near the end of its life. Replacing both at once costs a bit more upfront but saves you another service call in 6 to 12 months.
What's the warranty on a new spring? We offer a two-year parts warranty on all springs we install. Labor is guaranteed for 30 days. This covers defects, not normal wear.
How can I prevent spring failure? Keep springs clean and lightly lubricated with silicone spray every six months. Avoid slamming the door. Have springs inspected every three years, especially if your door is over seven years old.
