Garage Door Springs in Mill Valley: When to Repair vs. Replace
2026-06-05 7 min read
In our years serving Mill Valley, we've seen this problem again and again: a garage door that won't budge, and the culprit is almost always a broken spring. The good news is that a snapped spring doesn't automatically mean you need a whole new door. Understanding which type of spring failed, and whether repair or replacement makes sense, saves you time and money.
What Are Garage Door Springs, and Why Do They Matter?
Your garage door weighs between 300 and 500 pounds. Without springs, opening it manually would be impossible. Two main types carry that load: torsion springs and extension springs. Torsion springs twist and unwind above the door, while extension springs stretch and contract on either side. Both types work under enormous tension, which is why a snapped spring is dangerous and requires professional attention.
Springs typically last between seven and nine years, depending on how often you use your door. A door that opens and closes ten times daily wears springs faster than one used three times daily. Once a spring fails, the other compensates temporarily, but it's under double stress and won't last long.
Torsion vs. Extension: Knowing What You Have
Torsion springs sit horizontally above your door opening and are generally more durable. If one snaps, you'll hear a loud bang and your door becomes completely inoperable. Extension springs hang vertically and work in pairs. If one breaks, the door may still move, but unevenly and with strain. Both failures warrant the same response: call a professional immediately.
Don't attempt to replace springs yourself. The tension stored in these components can cause serious injury. Our team at Garage Door Company Mill Valley handles spring replacement with the proper tools and safety protocols. We also service customers throughout the broader Bay Area, including Sausalito and San Rafael.

Repair vs. Replace: What's the Right Call?
When a single extension spring snaps, repair often makes sense. We can replace just that spring and rebalance the door, restoring full function at a fraction of replacement cost. However, if both springs are original and the door is over eight years old, replacing both together is wiser. Springs wear in pairs, and replacing only one leaves the other vulnerable to failure within months.
For torsion springs, replacement is almost always the answer. A single failed torsion spring means the entire assembly needs attention, and technicians typically install a new pair to ensure balanced operation and longevity. See our 5 warning signs your garage door springs need replacement for more detail on recognizing failure before it happens.
The cost of a spring repair or replacement varies based on spring type, door weight, and whether you need same-day service. A basic extension spring replacement runs less than a torsion pair. Emergency calls outside business hours carry additional fees. Get an accurate estimate by calling us at 510-738-0812 or scheduling a free inspection through our contact page.
Why You Can't Wait
A broken spring isn't a nuisance you can ignore for a week. Your door won't function safely or reliably, and the remaining spring (or springs) deteriorates rapidly under extra load. Waiting increases the risk of a second failure, which compounds repair costs and leaves you without garage access. If your door is stuck closed, check our guide on garage door stuck closed in Mill Valley to rule out other causes first.
Finding the Right Estimate
When you call for a spring repair estimate, a qualified technician will inspect both springs, check the door balance, and recommend repair or replacement. Honest shops won't oversell you. If one spring is clearly at end of life and the other is newer, targeted repair makes sense. If both are aging, replacement of the pair ensures years of trouble-free operation.

Frequently Asked Questions
How long do garage door springs last? Quality springs typically last 7 to 9 years with normal use (about 10,000 open-close cycles). Heavy use shortens lifespan. Regular maintenance and lubrication extend life slightly, but springs are wear items that eventually need replacement.
Can I replace just one spring if both are broken? Technically yes, but it's not recommended. Replacing only one torsion or extension spring leaves the other under stress. Both should be replaced together to ensure balanced door operation and prevent premature failure of the remaining spring.
What does a snapped spring cost to fix? Extension spring replacement typically costs between $150 and $300 per spring. Torsion spring replacement for a pair ranges from $200 to $400, depending on door weight and local labor rates. Emergency or same-day service adds additional fees.
Is a broken spring an emergency? Yes. A snapped spring makes your door unsafe and inoperable. Do not attempt to force the door open or closed. Call a professional immediately to prevent injury and further damage to the door or opener.
How do I know if my springs are about to fail? Signs include a creaking or squeaking sound during operation, uneven door movement, the door closing faster than normal, or visible gaps or rust on the spring. If you notice any of these, read our warning signs guide and schedule an inspection right away.
