You hit the button, the opener motor hums, and the door barely moves. or doesn't move at all. This is one of the most common calls Garage Door San Diego receives, and the cause is almost always the same: a broken torsion spring.
Spring failures feel sudden, but they're rarely unexpected if you know what to look for. Here's a straightforward breakdown of what's happening, what it costs, and what you should. and shouldn't. do about it.
Garage door springs are rated by cycles. one cycle equals one open and one close. A standard spring is typically rated for around 10,000 cycles. If you open your garage door four times a day, you'll hit 10,000 cycles in roughly seven years. Higher-cycle springs rated for 20,000+ cycles last longer, but they're not standard equipment on most doors.
In San Diego, coastal humidity and salt air accelerate the corrosion process on spring metal, potentially shortening that lifespan. Add in the daily temperature swings between warm afternoons and cool coastal nights. which cause metal to expand and contract. and you have a recipe for springs that wear faster than the rated cycle count might suggest.
The bottom line: springs break because they're used up. It's not a defect, it's a mechanical reality. What matters is catching the warning signs early rather than being stranded in your garage on a Tuesday morning.
A few clear signs point directly to a broken or failing spring:
- The door won't open manually or feels extremely heavy when you try to lift it by hand, The opener runs its full cycle but the door barely lifts or stays near the floor, You hear a loud bang from the garage (that's often the sound of a spring snapping under tension) - The door opens a few inches and then stops, even though the opener sounds like it's working fine, The door hangs unevenly. one side higher than the other
If you look above the door when it's closed and see a gap in the coiled spring mounted on the metal rod, that's a broken torsion spring. confirmed.
Most residential garage doors in San Diego use one or two torsion springs mounted above the door on a steel shaft. Double-car doors typically have two springs working together.
Here's something reputable technicians will tell you upfront: if one spring breaks, the other is the same age and has experienced the same number of cycles. Replacing only the broken one means you'll likely be making another service call within a few months when the second one goes. Most homeowners find it makes more financial sense to replace both at once.

Here's honest, current pricing to set expectations:
- Single torsion spring replacement: roughly $200,$350 installed, depending on the spring size and company - Two torsion spring replacement: roughly $280,$500 installed - Labor alone from a San Diego technician typically runs $75,$150
San Diego repair costs run a bit higher than other parts of California. that's simply the local cost of doing business. Be cautious of quotes that seem dramatically low. Springs sold cheaply are often low-cycle parts that will fail sooner, putting you right back in the same situation within a few years.
Always ask: what cycle rating are the springs you're installing? A reputable tech will tell you without hesitation. High-cycle commercial-grade springs cost more but are worth the difference in the long run, especially given how San Diego's coastal environment ages metal hardware.

This is one of the few garage door topics where the answer is genuinely non-negotiable: don't replace torsion springs yourself.
Torsion springs operate under enormous tension. enough to cause serious injury if a spring slips, a winding bar kicks, or a cable lets go unexpectedly. These are not the kind of repairs where watching a YouTube video is adequate preparation. Professional technicians use specialized winding bars and follow strict safety procedures because the risk of injury without them is real.
Extension springs (the ones running along the sides of the door track rather than above it) carry similar risks. If you're not certain which type you have, look above the closed door. a large coiled spring on a horizontal rod means torsion. Thin springs running parallel to the horizontal tracks are extension springs.
For everything else. lubricating rollers, tightening bolts, cleaning tracks. DIY is absolutely fine. Springs are where you call a pro. You can browse our services page to understand the full scope of what a trained technician handles.
If you're in Carlsbad, Oceanside, or other North County coastal communities, the salt air corrosion issue is amplified even compared to central San Diego. When getting springs replaced in these areas, specifically ask about galvanized or oil-tempered springs rather than standard-finish hardware. The upcharge is modest and the lifespan difference is meaningful.
Can I still use my garage door with a broken spring? Technically you can open it manually, but it will be extremely heavy. garage doors typically weigh 150,400 pounds, and the spring system counterbalances that weight. Repeatedly operating the door without springs puts enormous strain on the opener motor and cables, often causing additional damage. It's better to leave it closed and call for service.
How long does a spring replacement take? For a standard residential torsion spring replacement, most experienced technicians complete the job in 45 minutes to an hour, often on the same day you call. Most service trucks carry common spring sizes as standard stock.
Should I upgrade to higher-cycle springs when replacing? In San Diego, yes. especially if you're within a few miles of the coast. Standard springs rated for 10,000 cycles will likely last 7,10 years with average use. High-cycle springs rated for 20,000,30,000 cycles cost more upfront but can last significantly longer and tend to be made from heavier-gauge steel that resists corrosion better. It's the more cost-effective choice over a 15-year window.
