Garage Door Spring Replacement in Covina: What You Need to Know Before Calling a Pro
2026-04-18 7 min read
If you've ever walked into your garage in the morning and hit the opener button only to watch your door groan, shudder, and refuse to budge, there's a good chance a broken spring is to blame. It happens to homeowners all over Covina. sometimes without any warning at all. Understanding how springs work, what failure looks like, and what a fair repair costs can save you time, money, and a lot of frustration.
How Garage Door Springs Actually Work
Your garage door looks like it's being powered by the opener motor, but the real heavy lifting is done by the springs. A standard garage door weighs anywhere from 150 to 400 pounds, and the springs carry nearly all of that load every single time the door moves.
There are two types you'll encounter:
- Torsion springs. mounted horizontally above the door opening on a metal shaft. They twist (torque) to store and release energy. Most modern Covina homes with sectional roll-up doors use this style. - Extension springs. run alongside the horizontal tracks on either side of the door. They stretch to store energy and are more common on older doors.
Torsion springs are generally the safer, longer-lasting option. They stay contained if they break, whereas a snapping extension spring can fly across the garage with serious force.
Why Covina's Climate Is Hard on Springs
Covina sits in the San Gabriel Valley, where summers are genuinely hot. Temperatures regularly push into the upper 80s and can spike past 95°F during peak heat stretches. That heat takes a real toll on metal components. Misaligned tracks, warped panels, and strained garage door springs are common in summer when everything expands under the heat.
On the flip side, winter nights in Covina do drop. sometimes into the low-to-mid 40s. Cold temperatures can cause springs to become more brittle and less responsive, increasing the chance of a snap during those cold early morning departures. If your springs aren't lubricated regularly, they're also more susceptible to rust and corrosion year-round, especially during the wet season.
Many of the older homes in Covina. particularly the midcentury ranch-style properties throughout the Charter Oak area and neighborhoods closer to downtown. still have their original spring systems. A door installed in the 1970s or 80s is almost certainly overdue for a spring inspection or replacement.
Warning Signs Your Springs Are Failing
Don't wait for a complete break. Watch for these early signals:
- The door won't open at all. or only rises a few inches then stops - Loud bang from the garage. a torsion spring snapping sounds like a gunshot - Visible gap in the coil. a broken torsion spring will have a clear separation in the coil - Door feels extremely heavy. when springs lose tension, the full weight of the door shifts to the opener motor - Uneven movement. one side rises faster than the other, causing the door to tilt - Cables hanging loose. broken springs often cause the lift cables to go slack

What Spring Replacement Costs in Covina
Here's a realistic breakdown for the Covina area and the broader San Gabriel Valley:
- Extension springs: $120,$200 per spring, including labor - Torsion springs: $150,$350 per spring, including labor - Full torsion spring system (both springs): $300,$600 is typical for most residential doors in the LA County area
If you need to convert from an extension spring system to torsion springs. which many older Covina homes do. expect to pay $400,$800 for the full conversion. It costs more upfront but gives you a safer, more balanced, longer-lasting system.
One piece of advice worth repeating: always replace both springs at the same time, even if only one has snapped. Springs wear at roughly the same rate, so if one has gone, the other is likely close behind. Replacing both during a single service call saves you a second trip charge and keeps the door balanced.

DIY vs. Hiring a Professional. Be Honest With Yourself
This is one of those repairs where the honest answer is: leave it to a pro. Torsion springs are wound under extreme tension. A mistake during installation or adjustment can send hardware flying at high speed. we're talking potential for serious injury or worse. Unlike changing an outlet or patching drywall, there's no safe "beginner" version of this job.
A professional technician has the winding bars, tensioning tools, and experience to size the spring correctly based on your door's weight and height. An incorrectly sized spring doesn't just fail faster. it puts uneven stress on the opener motor, cables, and tracks, leading to more repairs down the road.
Garage Door Covina's technicians carry the most common torsion and extension spring sizes on their trucks, which means most spring replacements can be completed in a single visit without waiting on parts.
How Long Should New Springs Last?
Most residential torsion springs are rated for 10,000 cycles. A cycle is one open-and-close sequence. If your household opens the garage door four times a day, that works out to roughly seven years before the springs approach their rated limit. High-cycle springs. typically rated at 20,000+ cycles. cost a bit more upfront but can double the service life.
To get the most out of new springs, keep up with regular lubrication and inspection. a light coat of silicone-based lubricant on the coils every few months goes a long way in Covina's climate.
Frequently Asked Questions
Q: Can I open my garage door manually if a spring is broken? A: Technically yes, but you shouldn't try to do it by yourself. Once a spring breaks, your door can weigh 200,400 pounds with no counterbalance. Lifting it manually risks injury and can damage the opener, cables, and tracks. Pull the red emergency release cord and get professional help before attempting to operate the door.
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 horizontal metal rod with one or two large coiled springs mounted to it, that's a torsion spring system. If you see springs running along the horizontal tracks on each side of the door, those are extension springs.
Q: Is it worth upgrading to higher-cycle springs when I replace them? A: For most Covina homeowners, yes. especially if you use the garage as a main entry point. The price difference is usually modest (often $30,$60 more per spring), and you could get twice the lifespan. It's one of those upgrades that genuinely pays for itself.
