A customer called last Tuesday morning. Her garage door was stuck halfway up, and she couldn't get it down. One look told me everything: a broken torsion spring. She asked the question I hear at least twice a week in San Marcos: "How much will this cost, and can you fix it today?" The answer is honest and direct. Most spring replacements run between $300 and $600, and yes, we do same-day service.
Garage door springs are under constant tension. They counterbalance the weight of your door, making it light enough to open and close smoothly. A typical residential door weighs 300 to 400 pounds. The springs handle that load thousands of times each year.
Springs fail because metal fatigues. Even quality torsion springs last only 7 to 9 years with regular use. Humidity and temperature swings in San Marcos accelerate wear. Salt air from nearby coastal areas, especially if you're in Carlsbad or Oceanside, can corrode hardware faster too. When a spring snaps, your door becomes dead weight. It won't open, and it won't stay up safely.
Most homes in San Marcos use torsion springs. These wind tightly above the door and twist to create lift. They're safer and last longer than extension springs, which run along the sides of your door opening.
If your door has extension springs and one snaps, you'll see it immediately. The spring will hang loose or dangle. With torsion springs, the break is less obvious, but the door becomes immobile. Either way, don't attempt a DIY fix. Springs carry enough tension to cause serious injury.
Here's where I'm straight with you. A single torsion spring replacement typically costs $200 to $350 in labor and materials. If both springs are original and one snapped, the second is close behind. Replacing both at once runs $400 to $600 total. That's still cheaper than replacing them separately six months apart.
The cost depends on your door's weight, spring size, and whether your springs are original equipment or aftermarket. If you want a detailed breakdown before we start work, we provide a free estimate.

A snapped spring isn't just inconvenient. It's a safety hazard. Your garage door opener will work harder trying to lift a dead door, which burns out the motor faster. Your door can slip and fall, damaging your car or creating a gap that lets pests in.

How do I know if my garage door spring is broken? Your door won't open or close, or it opens unevenly. You may hear a loud bang when the spring snaps. Torsion springs are harder to see, but extension springs hang loose or dangle visibly.
Can I replace a garage door spring myself? No. Springs are under extreme tension and can cause serious injury or death if mishandled. Always hire a professional. DIY attempts void warranties and create liability issues.
How long does a spring replacement take? Most jobs take 30 minutes to an hour. We arrive with the right parts, remove the old spring, install the new one, and test the door's balance.
Do both springs need replacement if one breaks? Usually yes. If one original spring has failed, the other is near the end of its life. Replacing both prevents a second breakdown weeks later and ensures balanced operation.
What's the difference between a spring estimate and a quote? An estimate is an educated guess. A quote is a binding price for specific work. We provide both. Read our full breakdown on estimates versus quotes.
