Garage Door Springs in Mill Valley: Real Costs & When to Call
2026-07-07 7 min read
A customer called last Tuesday with a snapped spring and panic in her voice. She'd gotten a quote for $800 and wasn't sure if that was fair. The truth: garage door springs in Mill Valley typically run $150 to $400 per spring, plus labor. You're not overpaying if you understand what you're buying.
What Are Garage Door Springs and Why They Cost What They Do
Your garage door weighs 300 to 500 pounds. Springs don't lift it directly. Instead, they counterbalance the weight, making your opener's job manageable and your door smooth to operate. Without functioning springs, your opener strains and fails prematurely, turning a $200 repair into a $500 problem.
Two types exist: torsion springs (wound around a rod above the door) and extension springs (stretched along the sides). Torsion springs are more durable, last 7 to 9 years, and cost more upfront. Extension springs wear faster and need replacement sooner, but they're cheaper individually.
The cost varies because springs aren't one-size-fits-all. A heavier door or custom installation adds expense. Materials matter too. Commercial-grade springs hold up longer than residential versions. Garage Door Company Mill Valley stocks both, and we'll help you pick the right one for your actual use, not the fanciest option.
Common Spring Problems and Real Costs
A snapped spring is sudden and jarring. Your door won't open or closes unevenly. This isn't a tune-up situation. You need replacement, not repair.
Spring wear happens gradually. Squeaking, slow opening, or a door that won't stay up are early warnings. A maintenance inspection (covered in our garage door maintenance guide) catches these before failure and saves you emergency rates.

The cost difference between proactive replacement and emergency repair is real. Same-day emergency service typically adds $100 to $200 to the base price. If you catch the problem during business hours on a Tuesday, you pay less than if your door fails on a Saturday night.
How to Get an Accurate Estimate
Don't compare quotes by price alone. A cheap estimate that skips the second spring or uses undersized hardware will cost more later.
A proper estimate includes:
Spring type and size. Your door's weight determines spring specifications. A standard residential single-car door needs different springs than a heavy wood or double-car setup.
Labor time. Torsion spring replacement typically takes 1 to 2 hours. Extension springs take 30 to 45 minutes. Complexity increases if your door has an old opener or custom frame.
Parts warranty. Quality springs come with 5 to 10 year warranties. Cheap springs don't. That warranty matters.
Both springs or one? If one spring snapped, the other is aging. Replacing only one creates imbalance and burns out your opener faster. Most pros recommend replacing both at once, even if only one failed.
When you call for a free estimate near you, ask these three questions: What's the spring type? Does the quote include both springs? What's the warranty? Our team at Garage Door Company Mill Valley's services answers all three before you decide.
Avoiding the Overspend Trap
The biggest mistake homeowners make is treating a snapped spring as an emergency when it's not. If your door is stuck closed, yes, call immediately. But if it's stuck open and your car is inside, you have time to get competitive quotes. Take two hours to call three local providers.
Avoid shops that push you toward replacement when repair is possible. If your opener works fine and only one spring shows wear, sometimes a single replacement makes sense. Our repair vs. replace guide walks through that decision.
Seasonal factors matter in Mill Valley. The fog and moisture we discussed in our weatherproofing post accelerates spring rust and wear. If you're in an older home near the coast, expect springs to age faster. Budget for replacement sooner.
Next Steps
Springs are critical and dangerous to replace yourself. The tension is extreme, and mistakes cause injury. Hire a licensed technician. The $200 to $300 you save by DIY isn't worth a trip to the ER.

Frequently Asked Questions
How long do garage door springs last? Torsion springs last 7 to 9 years with normal use. Extension springs wear faster, typically 5 to 7 years. Frequency of door cycles and climate affect lifespan. Coastal areas like Mill Valley see faster degradation due to moisture.
Can I replace just one spring? Technically yes, but not recommended. If one spring failed, the other is similarly aged and stressed. Replacing both ensures balanced operation and prevents opener strain. Single replacement costs less upfront but often leads to a second failure within months.
What's the difference between torsion and extension springs? Torsion springs wind around a rod above the door and are more durable and expensive. Extension springs run along the sides and are cheaper but wear faster. Torsion is standard on newer homes; extension on older garages.
Is spring replacement an emergency? Only if your door is stuck closed and blocking your car. If it's stuck open or operating unevenly, you have time to get quotes. Emergency rates apply only when you need same-day service outside business hours.
How much does a garage door spring replacement cost? Springs themselves run $150 to $400 each depending on type and door weight. Labor adds $150 to $300. Total for both springs is typically $500 to $1,000 installed. Emergency service adds $100 to $200.
