If your garage door suddenly feels impossibly heavy, makes a loud bang in the middle of the night, or only opens a few inches before stopping, there's a good chance you're dealing with a broken spring. For homeowners in Temple City. where attached two-car garages are standard on everything from mid-century ranch homes along Live Oak Avenue to newer Mediterranean Revivals near the Arcadia border. a broken spring means your primary entry point to your home is out of commission. Here's what you need to know.
Your garage door can weigh anywhere from 150 to over 400 pounds. Springs do the heavy lifting. literally. They store mechanical energy when the door closes and release it when you open the door, counterbalancing the weight so your opener motor (and your back) aren't doing all the work.
There are two main types:
Torsion springs sit horizontally above the door opening on a metal shaft. They twist to store energy. Most newer homes in Temple City use torsion spring systems because they're more balanced and longer-lasting. typically rated for 10,000 to 15,000 cycles.
Extension springs run along the horizontal tracks on either side of the door. They stretch and contract with the door's movement. Older homes and lighter single-car doors often use extension springs. They're more common on the smaller, older garages you'll find in the cottages and ranch-style homes built in the 1940s and 1950s that are still standing throughout Temple City.
Springs don't always snap without warning. Watch for these signs:
- The door feels unusually heavy when you try to lift it manually. A properly balanced door should stay in place when you lift it halfway. If it falls, the springs aren't doing their job. - Loud bang from the garage. many homeowners describe it as a gunshot. That's often a torsion spring snapping under tension. - The door opens only 6 inches then stops. Most modern openers have a built-in safety feature that halts operation when it detects the resistance of a broken spring. - Visible gap in the spring coil. You can often see a separation in a broken torsion spring by looking above the door. - One side of the door hangs lower than the other. This usually means one extension spring has given out.
If you notice any of these signs, stop using the door and contact a professional right away.
Temple City sits in the San Gabriel Valley and sees hot, dry summers with temperatures regularly reaching into the 90s. and occasionally spiking above 100°F. While the winters are mild compared to most of the country, the daily temperature swings between cool mornings and hot afternoons put real stress on metal components over time. Repeated expansion and contraction gradually fatigues spring metal, and springs that are already near the end of their rated cycle count are much more vulnerable to sudden failure during these temperature shifts.
This is the most important thing in this entire post: do not attempt to replace garage door springs yourself.
Torsion springs are under enormous tension. we're talking hundreds of pounds of stored force. A spring that releases unexpectedly can cause catastrophic injury. Professional technicians use special winding bars, safety cables, and years of hands-on experience to handle this work safely. Even extension springs, which seem more approachable, can snap violently if mishandled.
This isn't a job like replacing a light fixture or patching drywall. It's genuinely dangerous without the right tools and training. Check out our garage door safety features guide if you want a deeper understanding of why tension-based components require professional attention.
Most standard springs are rated for about 10,000 cycles. one cycle being one open and one close. If you use your garage door four times a day, that works out to roughly seven years. High-cycle springs rated at 25,000 or even 50,000 cycles are available and worth the upfront cost for active households. When Garage Door Temple City replaces springs, we always discuss cycle ratings with homeowners so you're not back in the same situation in a few years.
If your home still has the original springs from when it was built in the 1980s or earlier, those springs are almost certainly overdue for replacement. even if they haven't snapped yet.
A technician will: 1. Inspect both springs (even if only one broke. the other is likely near the end of its life too) 2. Check cables, drums, and the overall door balance 3. Replace springs with the correct size and cycle rating for your door's weight 4. Re-test door balance and opener force settings 5. Lubricate moving parts before leaving
The whole job typically takes under two hours for a standard residential door. Most repairs can be completed the same day. If you're in Temple City or nearby Arcadia, getting a technician out quickly is the priority. leaving a door inoperable overnight is a real security concern.

Q: Can I use my garage door with a broken spring? A: You technically may be able to force it open manually, but it's not safe. The door is extremely heavy without spring support, and using your electric opener with a broken spring can burn out the motor or cause the door to come down suddenly. Stop using it and call for service.
Q: How much does garage door spring replacement cost in Temple City? A: Spring replacement typically ranges from $150 to $350 for most residential doors, depending on the type of spring, cycle rating, and whether both springs need replacement. High-cycle upgrade springs cost more upfront but last significantly longer. Always get a quote that includes labor, parts, and a post-repair balance test.
Q: Should I replace both springs at once, even if only one broke? A: Yes. almost always. If one spring broke, the other is the same age and under similar wear. Replacing both at the same time saves you a second service call in the near future and ensures the door operates evenly. Most technicians will recommend this, and it's sound advice.
