If your garage door suddenly stopped working this morning, there's a good chance a spring is to blame. It happens more often than people expect — and it almost always seems to happen at the worst possible moment. Whether you're in one of Montebello's older ranch-style neighborhoods off Beverly Boulevard or in a newer home up in the Metro Heights development, the physics of a broken garage door spring are the same: your door isn't going anywhere until the spring is fixed.
Here's what you need to know about garage door springs, how to spot trouble before a full failure, what it's going to cost you, and why calling a professional is the only safe move.
Your garage door is heavy — a standard single-car door weighs 130 to 150 pounds, and a two-car insulated steel door can exceed 300 pounds. Springs counterbalance that weight, making it possible for the opener motor (or your own arm) to lift the door with minimal effort. Without functioning springs, the opener alone can't carry the load.
There are two main types:
Mounted horizontally above the door opening, torsion springs coil around a metal rod and store energy as the door closes. They're the more common type in modern Montebello homes and tend to last longer — typically 7 to 14 years or 10,000 to 20,000 cycles.
These run along the horizontal tracks on each side of the door and stretch as it closes. They're often found on older tilt-up doors, which are still common in some of Montebello's mid-century homes built between the 1950s and '70s. Extension springs are generally less expensive to replace but have shorter lifespans.
If you're not sure which type you have, check out our Understanding Garage Door Springs guide for a full breakdown.
A spring doesn't always snap without warning. Watch for these red flags:
- The door won't stay open on its own — it slowly creeps back down - The opener motor runs but the door barely moves — the motor is fighting the weight alone - The door looks crooked or uneven when opening or closing - You hear a loud bang from the garage — that's often the sound of a spring breaking - Visible gaps in the coils of a torsion spring mean failure is imminent - Rust or corrosion on the spring — even in Montebello's relatively mild Mediterranean climate, temperature swings between dry summers and wetter winters can accelerate rust on older springs
Don't ignore these warning signs that your garage door needs professional repair — a failed spring can damage your cables, strain your opener motor, or leave your car stuck inside.
In the greater Los Angeles area, garage door spring replacement typically runs $200 to $400 per spring, depending on spring type, door size, and the specific company you hire. That range reflects the urban labor market here — costs in LA County tend to run higher than national averages.
A few things that affect your final price:
- Spring type: Torsion springs cost more than extension springs, but they last longer and are generally safer - Door weight and size: Heavier two-car doors need heavier-duty springs with precise weight ratings - Replacing both at once: Most pros — including our team at Garage Door Montebello — strongly recommend replacing both springs at the same time, even if only one is broken. Springs wear at the same rate, so the second one is likely close behind. Replacing both during the same visit also reduces your labor costs - Spring quality: Budget springs rated for 5,000 to 10,000 cycles may fail in five to seven years. Higher-cycle springs rated for 25,000+ cycles cost more upfront but save money in the long run - Emergency or after-hours service: Off-hours calls carry a premium — if you can wait until the next business day, you'll usually pay less
If your door also has frayed cables, worn rollers, or an aging opener, it's worth bundling those repairs into the same service call. Addressing everything at once is almost always cheaper than scheduling separate visits.
Short answer: no. Longer answer: absolutely not.
Garage door springs are under extreme tension. A torsion spring that snaps during DIY installation can cause serious injury — we're talking broken bones, eye injuries, or worse. Improper installation also causes premature failure and can damage your opener or cables, turning a $300 repair into a $600+ job.
This isn't the kind of project where watching a YouTube video is enough preparation. It requires specialized winding bars, a solid understanding of spring sizing for your specific door weight, and experience handling components that can release energy violently if mishandled.
Leave this one to a licensed technician. Reach out to our team and we can usually get to you the same day.
With quality springs and proper installation, you can expect 7 to 12 years of reliable service under normal use. A few things that extend spring life in the Montebello area:
- Annual lubrication with a silicone or lithium-based spray — this is especially important as temperatures shift between Montebello's dry summers and cooler, wetter winters - Keeping springs clean and free of dust buildup, which is common in our inland air environment - Scheduling a tune-up every couple of years to check tension, cable condition, and hardware — our full services page covers what a standard maintenance visit includes
Neighbors in nearby Monterey Park and Commerce deal with the same spring wear patterns we see here — the dry heat bakes the grease out of springs faster than you'd expect, and winter moisture can accelerate rust on unprotected coils.
Q: My garage door opened halfway and then stopped. Is it a spring problem? A: It could be. A partially broken or severely weakened spring can cause the opener to stall mid-cycle because it can't manage the full weight of the door. It could also be a cable issue. Either way, stop using the door and have a technician inspect it — forcing an unbalanced door risks further damage to the opener, cables, and tracks.
Q: How do I know if I have torsion or extension springs? A: Look above the door when it's closed. If you see a single spring (or two springs side by side) mounted horizontally on 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. Older Montebello homes with tilt-up doors almost always have extension springs.
Q: Is it worth replacing the springs on an old garage door? A: If the door panels, tracks, and opener are in reasonable shape, yes — spring replacement is far more cost-effective than buying a new door. But if your door is 15 to 20 years old and has multiple issues, it may be worth evaluating a full replacement instead. A technician can give you an honest assessment on the spot.
