If you've ever heard a sharp, explosive bang come from your garage. loud enough to make you think something fell off the wall. there's a good chance a garage door spring just snapped. It's one of the most common calls we get at Garage Door Antioch, and it catches homeowners completely off guard every time. Understanding what springs do, how to spot the warning signs, and what to expect from a replacement can save you a lot of stress (and money).
Your garage door looks like it's powered entirely by the opener motor, but that's not really the case. Springs do the real heavy lifting. They store mechanical tension and counterbalance the weight of the door. which on a standard two-car steel door can easily reach 200,300 pounds. Without working springs, your opener is essentially trying to drag dead weight up a track.
There are two main types:
- Torsion springs. mounted horizontally above the door opening on a metal shaft. Most homes in Antioch's Deer Valley and Lone Tree Valley neighborhoods use these, especially in homes built in the 1990s to 2010s that feature two- and three-car garages. - Extension springs. run along the horizontal tracks on either side of the door. More common in older homes north of the California Delta Highway, like the ranch-style and 1950s-era homes you'll find there.
Torsion systems generally lift more smoothly and are considered safer because when they break, the tension is more contained.
Antioch's climate is harder on garage door hardware than many homeowners realize. Summers here are long, hot, and arid. temperatures regularly push into the upper 90s and occasionally past 100°F. Winters flip to cool, wet conditions with the rainy season running from December through February. That repeated expansion and contraction of metal through extreme temperature swings accelerates spring fatigue.
Most residential springs are rated for about 10,000 cycles. one cycle equals one open and one close. If you're using your garage door four times a day (which is typical for a family with two cars), that's roughly 1,460 cycles per year, meaning you can expect a spring to wear out within 7,10 years under normal conditions. Heat stress can shorten that window.

Springs rarely fail without giving some advance notice. Watch for these:
- The door feels heavier than usual when you try to lift it manually. Disconnect the opener and try lifting the door by hand. a balanced door should stay put at about waist height with minimal effort. - The door opens unevenly, sagging on one side as it goes up. - Visible gaps or separation in the spring coil. a broken torsion spring will often have a visible gap where it snapped. - The opener runs but the door barely moves. the motor is working, but without spring tension, it can't do much. - A loud bang with no other explanation. This is the classic broken spring sound that many Antioch homeowners describe as a firecracker or a 2x4 dropping.
If you're seeing other warning signs beyond the spring, our guide on early warning signs your garage door needs attention covers the full picture.
Short answer: no, and we'd strongly advise against it. Torsion springs are wound under extreme tension. enough to cause serious injury if the spring slips or the winding bars aren't handled correctly. This isn't a scare tactic; it's a genuine safety issue that sends people to the ER every year.
Extension springs are slightly more accessible, but they still require precise sizing and careful installation to ensure the door operates safely. Even a slightly wrong spring size can throw the door off balance and wear out your opener prematurely.
For spring work specifically, professional replacement is the right call. Visit our services page to see exactly what's included in a spring replacement visit from Garage Door Antioch.
A proper spring replacement isn't just pulling off the broken spring and screwing in a new one. A thorough technician will:
1. Identify whether you have torsion or extension springs 2. Measure the wire diameter, inside diameter, and length to match the correct replacement 3. Replace the spring (or both springs. more on this below) 4. Set and test the tension 5. Balance the door manually before reconnecting the opener 6. Inspect cables, drums, bearings, and rollers while the door is already apart
On that last point. cables and springs wear at similar rates. If your spring broke after 10 years of service, your cables have been through the same 10 years. A good technician will flag anything that looks close to failure so you're not dealing with another breakdown in six months.
If you have two torsion springs (common on wider doors) and one breaks, it's almost always worth replacing both. Springs from the same installation wear at the same rate. if one failed, the other isn't far behind. Replacing just the broken one means you'll likely be scheduling the same service call in a matter of months.
Spring replacement in Antioch typically runs anywhere from $150 to $350 depending on the spring type, size, and whether you're replacing one or two. Torsion springs generally cost a bit more than extension springs. If cables or other components need attention during the same visit, those are usually added at a reasonable rate since the door is already apart.

Q: My garage door opener is still running but the door won't open. Is that a spring issue? A: Very likely, yes. When a spring breaks, the opener motor may still activate but struggle to lift the unbalanced door. You might hear the motor running without the door moving, or the door may rise just a few inches before stopping. Disconnect the opener and try lifting the door manually. if it feels extremely heavy or won't stay up on its own, a broken spring is the most probable cause.
Q: How long does a spring replacement take? A: A straightforward torsion spring replacement on a standard residential door typically takes 1,2 hours, including balancing and safety checks. If cables or other components need work at the same time, add another 30,60 minutes. Same-day service is usually available for spring failures since it's considered a priority repair.
Q: Is it safe to use my garage door with a broken spring? A: No. Operating a garage door with a broken spring puts severe strain on the opener motor, which can burn it out. More importantly, a door without proper spring tension can drop suddenly if the opener's safety mechanisms fail. Treat a broken spring as an out-of-service situation until it's repaired.
