5 Signs Your Garage Door Springs Need Replacement
2026-04-10 7 min read
If your garage door suddenly stops mid-track, slams down faster than it should, or refuses to budge in the morning, there's a good chance your springs are the problem. Springs are the unsung workhorses of any garage door system. and in Rosemead, where homes often date back to the postwar building boom of the 1950s and early '60s, plenty of those original spring systems are well past their prime.
Here's what every Rosemead homeowner should know about spotting spring trouble before it leaves you stranded.
What Do Garage Door Springs Actually Do?
Your garage door. whether it's the classic single-car setup on a ranch-style home near Garvey Avenue or a wider double-door on a newer two-story in the northeast neighborhoods. weighs anywhere from 150 to 400 pounds. Torsion springs (mounted horizontally above the door) and extension springs (running along the side tracks) do the heavy lifting, counterbalancing that weight so your opener motor doesn't have to strain.
When springs wear out or snap, the door becomes dangerously heavy. Your opener can't compensate for that. and neither can you safely.
The 5 Warning Signs
1. The Door Won't Open at All
This is the most obvious sign. If you hit the button and hear the motor running but the door barely moves or doesn't move at all, a broken spring is the most likely cause. A fully broken torsion spring often makes a loud bang. almost like a firecracker going off in your garage. when it snaps. If you heard that sound recently, stop trying to operate the door manually. The door is too heavy to lift safely without functioning springs.
2. The Door Opens Crooked or Unevenly
If one side of your door rises faster than the other, or the door looks visibly tilted as it moves, one spring may have failed while the other hasn't yet. This is common on two-spring systems, and it puts enormous stress on the cables, tracks, and opener. Left unchecked, it can cause cable fraying or track damage. turning a straightforward spring job into a much bigger repair bill. Check out our garage door safety tips for more on why uneven movement is a red flag you shouldn't ignore.
3. There's a Visible Gap in the Torsion Spring
Take a look at the horizontal spring above your garage door (don't touch it). If you see a gap of an inch or two in the coil, that spring has snapped. A properly wound torsion spring should look like a tight, continuous coil. A gap means it's done. No repair here. it needs to be replaced.
4. The Door Feels Extremely Heavy When Lifted Manually
Here's a simple test: disconnect your opener (pull the red emergency cord), then try to lift the door manually to about waist height and let go. A properly balanced door should stay in place or drift only slightly. If it crashes to the ground or feels like you're lifting a truck, your springs have lost their tension and are no longer doing their job. This test works well for homeowners in San Gabriel and Rosemead alike. it costs nothing and tells you a lot.
5. Squealing, Grinding, or Visible Rust
Rosemead gets around 300 sunny days a year, but the marine layer and winter rain. about 15 inches annually. can take a toll on unprotected metal. If your springs are visibly rusty or corroded, or if you're hearing new grinding sounds during operation, that's a sign the metal has degraded and the spring is approaching failure. Rust weakens the coil and can cause a premature snap. A little lithium-based lubricant applied every few months helps, but if the rust is deep, replacement is safer than maintenance at that point.
Torsion vs. Extension: Does It Matter for Cost?
Yes. and it's worth understanding before you call anyone. Torsion springs are more expensive to replace but last longer and are the safer design. In the Los Angeles area, torsion spring replacement typically runs $200,$500 per spring including labor, while extension springs are more affordable at around $120,$200 for the job. Most professionals. including the team at Garage Door Rosemead. will recommend replacing both springs at the same time even if only one has failed. Springs wear at roughly the same rate, so the second one is usually not far behind.
If you're getting quotes, be cautious of any torsion spring job priced under $200. that's a sign someone may be cutting corners on parts or skipping safety steps.
DIY or Call a Pro?
This is one garage door repair where the answer is almost always: call a professional. Torsion springs are under extreme tension. enough to cause serious injury if handled incorrectly. The tools required (winding bars, proper spring gauges) aren't standard household items, and an incorrect installation can cause premature failure or worse. This isn't about upselling you on a service call; it's genuinely one of the more hazardous home repairs a non-professional can attempt.
For the rest of your garage door system. lubrication, visual inspections, testing the auto-reverse. those are great DIY tasks. But spring replacement deserves a trained technician. You can learn more about what to expect from a full service visit before scheduling.
How Long Do Springs Last?
Most residential garage door springs are rated for 10,000 to 20,000 cycles, which translates to roughly 7,15 years for a typical household using the garage door a few times per day. If your Rosemead home has original springs from a 1960s or 70s build and they've never been replaced, they've almost certainly surpassed their lifespan. even if they haven't snapped yet.
Spring lifespan also depends on how well they've been maintained. Springs that are lubricated regularly and kept free of rust will last longer than those that are ignored year after year.
Frequently Asked Questions
Q: Can I still use my garage door if a spring is broken? Technically you can try, but you shouldn't. Without a functioning spring, the full weight of the door falls on your opener motor, which can burn it out quickly. More importantly, a door without proper spring tension is unpredictable and can drop suddenly. a serious safety hazard.
Q: Should I replace both springs even if only one broke? Yes, in almost every case. Springs on the same door age together. If one has failed, the other is likely close behind. Replacing both at the same time costs less than two separate service calls and keeps your door balanced.
Q: How do I know if I have torsion or extension springs? Look above your closed garage door. If you see one or two thick coiled springs running horizontally across a metal rod above the door opening, those are torsion springs. If you see springs running along the horizontal tracks on either side of the door, those are extension springs. Not sure? Contact us and we can walk you through it before scheduling.
