A snapped garage door spring is not a DIY fix. If your door suddenly won't open or feels heavy, a broken torsion or extension spring is the likely culprit. Most springs last 7 to 9 years and fail without warning. Replacing one costs $150 to $400 depending on the type and your door's weight. Call a professional same-day service to avoid getting trapped in your garage or driveway.
Your garage door weighs 300 to 500 pounds. Torsion springs (the heavy-duty coils above the door) counterbalance that weight so your opener doesn't strain. When a torsion spring snaps, the door becomes nearly impossible to lift by hand. Many homeowners hear a loud bang or crack, then find their door stuck halfway or completely immobile.
Extension springs, which run along the sides of the door, fail more gradually. You might notice the door closing unevenly or one side sagging. Either way, a broken spring means the door cannot operate safely. The weight shifts unevenly, stressing the cables and putting stress on your garage door opener. Ignoring the problem invites costlier damage.
Springs are under constant tension. Every time you open and close your door, the spring cycles. Over years, metal fatigue sets in. Rust accelerates failure, especially in San Diego's coastal climate where salt air speeds corrosion. Springs that aren't properly maintained fail sooner. Poor lubrication, extreme temperature swings, and repeated heavy use all shorten their lifespan.
If your door is older or you've never had springs serviced, failure is more likely. A professional inspection catches weak springs before they snap. That's cheaper than an emergency call when you're locked out of your garage.
A snapped spring replacement typically runs $200 to $400 in San Diego, depending on whether you have one or two springs. Torsion springs cost more than extension springs because they handle more weight. Most jobs take 1 to 2 hours. If you need same-day service, expect a small rush fee (usually $50 to $75 extra).

Waiting longer isn't smart. A stuck door blocks your driveway and leaves your garage vulnerable. If your opener tries to lift a door with a broken spring, you risk burning out the motor (another $300 to $500 expense). Getting a free estimate now prevents that bill later.
Never attempt to replace a garage door spring yourself. Torsion springs are wound under extreme pressure. If the wire slips, it can snap with enough force to cause serious injury. Even experienced DIYers should hire a licensed technician. The cost of professional service is worth the safety benefit and warranty protection.
If your door is stuck and you need it urgently, contact Garage Door San Diego for a same-day estimate. We assess the damage, confirm whether it's truly a snapped spring, and provide a transparent cost breakdown before we start work. See our emergency garage door service page for more on what to expect during an emergency call.
You can't stop springs from aging, but maintenance slows the process. Annual lubrication and inspection catch problems early. Springs that are properly maintained last closer to their full lifespan. If one spring fails, the other is likely near the end too. Many technicians recommend replacing both springs at once, even if only one snapped. This costs a bit more upfront but prevents a second failure weeks later.
Regular maintenance also keeps your opener running smoothly. A garage door that's maintained requires less effort from the opener motor, reducing wear overall. Check our garage door maintenance checklist for seasonal care tips specific to San Diego's weather.
If your door is 20+ years old and the springs fail, consider whether replacement makes sense. Older doors often have weak springs, worn cables, and tired openers. A new door with modern springs and an efficient opener costs $1,500 to $3,500 installed. That's more than a spring replacement, but a new system is quieter, safer, and more reliable. We can help you choose the right garage door for your home and budget.

How do I know if my garage door spring is broken? Your door won't open or feels extremely heavy. You may hear a loud pop or crack. If one side of the door sits lower than the other, the spring likely failed. Don't force the door open; call a technician right away.
Can I open my garage door manually if the spring is broken? Not safely. A broken spring removes the counterbalance, making the 300 to 500 pound door nearly impossible to lift without risk of injury. Use the emergency release only if you must get your car out, then call for service immediately.
How much does a garage door spring replacement cost in San Diego? Torsion spring replacement costs $200 to $400 depending on door weight and spring type. Extension springs are slightly cheaper. Same-day emergency service may add $50 to $75. Get a free estimate to confirm your exact cost.
How long do garage door springs last? Most springs last 7 to 9 years under normal use. Coastal humidity and salt air in San Diego speed corrosion and shorten lifespan. Proper lubrication and maintenance help springs reach their full life expectancy.
Should I replace both springs if only one broke? Yes, usually. When one spring fails, the other is near the end of its life too. Replacing both at once costs more upfront but prevents a second failure weeks later and saves you another service call.
