If you've ever walked into your garage in the morning, hit the button, and heard nothing but a loud bang followed by silence. you've experienced a broken torsion spring. It's one of the most common service calls we get here in Chula Vista, and for good reason. The combination of year-round use, coastal humidity, and the salt air drifting in from San Diego Bay creates conditions that can shorten the lifespan of garage door hardware faster than in drier inland communities.
Springs are the workhorses of your garage door system. Without them, your opener's motor would be trying to lift a 200,400 lb door on its own. it can't. Torsion springs (the large coiled springs mounted on a metal rod above your door) and extension springs (the longer, thinner springs running alongside the tracks on older doors) store and release mechanical energy every time your door moves.
Most residential torsion springs are rated for about 10,000 cycles. If you open and close your garage twice a day. which is typical in busy Chula Vista households heading out to work, school, or the freeway. that works out to roughly 7,10 years of use before the spring starts to wear down. In areas closer to the bay or the coastline, that timeline can shrink due to salt air accelerating metal fatigue.
Don't wait for a dramatic snap. Springs usually give some warning signs before they go:
- The door feels heavy when you lift it manually. Disconnect the opener and try lifting by hand. A properly balanced door should feel nearly weightless at waist height. If it feels like you're deadlifting, the springs are losing tension. - The door opens unevenly or sags on one side. With two springs, if one fails first, you'll notice the door tilting or jerking during operation. - Visible gaps in the spring coil. A broken torsion spring will show a clear separation. a gap of an inch or more in the coil. - The opener runs but the door barely moves. The motor is straining against a door it can no longer properly counterbalance. Keep reading our guide to warning signs your garage door needs repair if you're seeing other symptoms too. - A loud bang from the garage. This is usually the spring snapping. Many Chula Vista homeowners describe it as sounding like a gunshot.
Most homes built in planned communities like Otay Ranch, Eastlake, and Rolling Hills Ranch. the newer developments on Chula Vista's east side. typically have torsion spring setups, which are standard on modern sectional doors. If you're in an older home in the Hilltop or Terra Nova neighborhoods, or if your door swings up as one piece rather than sectioning, you may still have extension springs running along the side tracks.
Knowing which type you have matters, because the replacement process and cost differ between them.
Here's the honest breakdown for San Diego County:
- Single torsion spring: roughly $200,$280 installed - Two torsion springs (recommended): roughly $280,$380 installed - Extension springs (pair): roughly $150,$250 installed
When one spring breaks, most technicians. including our team at Garage Door Chula Vista. recommend replacing both at the same time. The reason is simple: if one spring has reached the end of its life, the other one has endured the same number of cycles. You'll likely be calling for a second repair within months if you only replace one.
This is worth saying plainly: torsion spring replacement is genuinely dangerous for non-professionals. The springs are under extreme tension. enough to cause serious injury or worse if they release unexpectedly during the process. No YouTube video is worth the risk. This isn't the same as tightening a hinge or lubricating your tracks (tasks any homeowner can handle. see our seasonal maintenance checklist for the safe DIY work). Spring replacement requires proper winding bars, the right replacement spring rated for your door's exact weight, and the experience to release tension safely.
If your spring breaks tonight, here's what to do: stop using the door entirely. Don't try to force it open or engage the opener. If your car is trapped inside, call for service. attempting to manually force a door with a broken spring can cause the door to fall suddenly.
A qualified technician will:
1. Inspect the full system. not just the springs, but cables, rollers, and tracks as well 2. Measure your door's weight and select springs with the correct cycle rating 3. Install and wind the new springs, then test balance 4. Make any cable or hardware adjustments needed
The job typically takes 45,90 minutes for a standard residential door. Ask about warranties. parts and labor should both be covered.

How long do garage door springs last in Chula Vista? Most torsion springs are rated for 10,000 cycles. Given Chula Vista's coastal humidity and salt air. especially in neighborhoods closer to San Diego Bay. springs may wear faster than in drier climates. Plan for a lifespan of 7,10 years with regular maintenance.
Can I open my garage door manually if the spring is broken? Technically yes, but it's not recommended without help. A sectional door without functioning springs can weigh several hundred pounds. If you must access the garage, have someone assist you and proceed very carefully. then leave the door down and call for service.
Should I replace one spring or both? Always replace both at the same time. Since both springs experience the same wear, replacing only the broken one typically results in the second spring failing within a few months, requiring another service call and additional cost.
