A snapped garage door spring means your door won't open, close, or balance properly. The spring has failed under tension, and attempting to force it will damage your opener or injure you. Call a professional for same-day replacement. DIY spring repair is genuinely dangerous and often costs more once damage compounds.
In our years serving Petaluma homeowners, we've seen this problem again and again: someone ignores squeaking or grinding noises, the spring finally breaks, then they waste time and money on band-aid fixes. This post explains what's happening, why you can't fix it yourself, and how much you should actually expect to pay. See our guide on smart garage door technology in petaluma: what you need to know before upgrading.
Garage door springs don't just fail overnight. They weaken over years of opening and closing.
Most residential torsion springs last 7 to 9 years. Extension springs wear out slightly faster. Once that lifespan ends, metal fatigue sets in. One morning, the spring gives out completely.
But springs also snap early when:
* The door is left open for long periods (springs bear constant load) * Rust builds up inside the spring (moisture and salt air in Sonoma County speeds this) * The spring was undersized for your door's weight * Cables became frayed and tangled around the spring
You might hear a loud BANG when it happens. That's the spring releasing all its tension at once. If you're in the garage, it's startling. If you're not, you'll just notice the door won't budge.
Don't try to manually lift the door. A garage door without a working spring weighs 300 to 400 pounds. You can't move it safely, and you risk dropping it on yourself or your car.
Don't use the garage door opener. Pressing the button when a spring is snapped will strain the opener motor and strip the gears. Repair costs jump from a spring replacement to opener replacement. That's the difference between $200 and $800.
Don't attempt spring replacement yourself. Torsion springs are under extreme tension. Releasing that tension without proper tools and training can cause serious injury. Extension springs are slightly safer but still dangerous if the cables snap during removal.
Our team at Garage Door Petaluma has seen DIYers make small mistakes that turn into big expenses. Let the professionals handle it.
A single torsion spring replacement typically costs between $150 and $300, depending on the spring's size and quality. Most garage doors have two springs, so budget $300 to $600 for a complete pair replacement.
Extension springs run slightly cheaper, usually $100 to $250 per spring. Labor adds another $100 to $150 per visit.
If your door has been sitting broken for weeks and the opener has been damaged from repeated attempts, you're looking at $800 to $1,200 total.

Springs fail eventually. That's unavoidable. But you can extend their life and catch problems early.
Listen for warning signs: squeaking, grinding, or the door moving slower than usual. These noises mean the spring is weakening. Lubricate the spring and hinges twice a year with a silicone-based garage door lubricant. Never use WD40 or general purpose oil; they attract dust and gum up the mechanism.
Have your door inspected annually. A technician will measure spring tension, check for rust and fraying cables, and replace springs before they snap. An ounce of prevention truly works here. Spring maintenance keeps your door running smoothly and catches problems before they strand you.

If one spring breaks and the other is more than five years old, replace both. Springs wear at similar rates. Replacing one now and the other in six months costs more in service calls and inconvenience.
New matched springs also ensure balanced door operation. A mismatched pair can cause the door to open unevenly, straining the opener and wearing out cables faster.
Feeling uncertain about the decision? Schedule a free quote and let our team assess whether one or both springs need replacement. We'll give you an honest estimate and explain the trade-offs.
When you call with a snapped spring, tell us if the door is stuck open, closed, or partially open. We'll arrive with replacement springs, cables if needed, and tools to complete the job in one visit.
The replacement takes 1 to 2 hours. We'll test the door multiple times to confirm it opens, closes, and balances correctly. If we spot worn cables or opener issues while we're there, we'll point them out and discuss options.
Emergency service costs the same as standard appointments in Petaluma. There's no premium for same-day response. We believe honest pricing builds trust.
How do I know if my spring is torsion or extension? Torsion springs sit horizontally above the door and twist to lift it. Extension springs run parallel to the door tracks on both sides. Torsion springs are stronger and last longer but cost slightly more to replace.
Can I open my garage door manually if the spring is broken? Yes, but it's unsafe and difficult. Disconnect the opener first using the red emergency release cord. Then lift slowly and have someone help you. Don't attempt this alone.
Will my homeowner's insurance cover spring replacement? Usually no. Garage door springs wear out naturally, which is considered maintenance. Coverage varies by policy, so check with your insurer, but don't count on reimbursement.
How often should I have my springs inspected? Every 12 months is ideal, especially in Petaluma where coastal humidity accelerates rust. Early detection saves money and prevents emergency breakdowns.
What's the difference between a snapped spring and a broken cable? A snapped spring loses tension and can't lift the door. A broken cable frays and tangles around the drum but the spring may still have tension. Both prevent operation, but the cause and fix differ. A technician must inspect to know for sure.
