A customer called last Tuesday morning. Her garage door wouldn't budge. When we arrived, the torsion spring above the door had snapped clean in half. She'd heard a loud bang the night before but thought nothing of it. Now she couldn't get her car out, and the door was stuck halfway open. This scenario plays out dozens of times each month across San Diego and surrounding neighborhoods. The good news: knowing what to watch for prevents this emergency.
Your garage door springs are under tremendous tension. A standard residential door weighs 300 to 400 pounds. Springs counterbalance that weight so your opener can lift it with minimal effort. Over time, metal fatigues. Springs last roughly 7 to 9 years with normal use, though that timeline depends on how often you open and close the door.
Two main types exist: torsion springs mounted above the door, and extension springs running along the sides. Torsion springs fail when the coil loses its ability to store and release energy. Extension springs snap when the metal simply can't take another cycle. Either way, you'll know something's wrong before the final break happens, if you're paying attention.
Listen for a loud bang or crack. That's often the spring giving way. But smaller clues come first. If your door feels heavier than usual when opening manually, one spring may already be weakened. Your opener might struggle, make unusual grinding sounds, or the door might open unevenly, with one side rising faster than the other.
Don't ignore these signals. A failing spring puts extra strain on your opener motor and can damage the entire assembly. If you notice anything off with your door's operation, schedule a free quote to have a professional check it out. A proper estimate takes minutes and costs nothing.
We understand the temptation to save money. But replacing garage door springs yourself ranks among the riskiest home repairs. Springs hold 10,000 pounds of force. A slip means broken bones or worse. Even experienced mechanics use specialized tools and work in pairs.
The cost of a professional replacement is reasonable insurance against injury. When you call for a same-day estimate, you're getting the knowledge of someone who's handled hundreds of these jobs. That's worth the investment.

Spring replacement cost varies based on spring type and door size. Torsion springs typically cost more than extension springs because they're harder to install and source. A single spring replacement might run anywhere from $150 to $400 in parts and labor. Both springs often need replacement simultaneously, since the second one isn't far behind if the first has failed.
We've broken down the full picture in our garage door spring replacement cost guide for San Diego, which covers what affects your quote and why transparent pricing matters.
The smartest approach is prevention. A garage door maintenance tune-up catches weakening springs before they snap. During an inspection, we listen for telltale signs, check spring tension, and look for rust or corrosion that accelerates wear.
If you haven't had your door serviced recently, our maintenance guide explains when and why San Diego homeowners should schedule one. Think of it like an oil change for your car. You're not fixing an emergency; you're avoiding one.
Regular lubrication also extends spring life. Springs need a light coat of garage door lubricant annually, not WD-40 or general-purpose oils. The right product keeps coils moving freely and slows rust development, especially in San Diego's coastal climate where salt air corrodes metal faster.
If your spring breaks right now, don't force the door up. You'll damage the opener. Call a professional immediately. Your car is stuck temporarily, but forcing the issue creates a bigger bill. We handle emergency calls throughout San Diego County and can usually arrive within hours.
While you wait, keep the garage door closed if it's safe to do so. If it's stuck open, at least keep it locked so nobody tries to open it further. Document what happened with a photo or two for your records.
The fix itself takes under an hour once our technician arrives. We'll replace the broken spring, check the entire system for damage caused by the break, and test everything before we leave. You'll get a clear estimate before work begins, no surprises.
How long do garage door springs actually last? Most springs last 7 to 9 years with regular residential use. Springs rated for 10,000 cycles might last longer if you open and close your door only once or twice daily. Frequent use, humidity, and salt air all shorten the lifespan.
Can I replace one spring or do both need replacing? If one spring has snapped, the second is usually close behind. We typically recommend replacing both simultaneously to avoid a second failure weeks later. It's more economical upfront than two service calls.
What's the difference between torsion and extension springs? Torsion springs wind tightly above the door and are harder to replace, making them costlier. Extension springs stretch along the sides and are simpler to install. Torsion springs are more durable and last longer in most cases.
Why does my door feel heavier when I try to open it manually? A weakened spring isn't providing full counterbalance. Never try to force it open. Call a professional to assess whether the spring needs replacement before the system fails completely.
How much does spring replacement cost in San Diego? Single spring replacement typically ranges from $150 to $400 depending on type and door size. If both springs need work, expect higher costs.
