Garage Door Spring Repair in Covina: What Broke, Why, and What to Do Next
2026-04-07 6 min read
You walked into the garage this morning, hit the opener button, heard a loud bang. or maybe nothing at all. and now your door won't move. If your door is sitting at the bottom and won't budge, or if it's crooked and straining, there's a very good chance you're looking at a broken torsion spring. It's the single most common garage door failure we see across Covina and the surrounding area, including homes in West Covina and Charter Oak.
Here's the honest breakdown: what broke, why it broke, and what your options actually are.
What a Garage Door Spring Actually Does
Your garage door is heavy. most residential sectional doors weigh between 130 and 200 pounds. The spring system (either a torsion spring mounted above the door or extension springs running along the side tracks) is what does the actual lifting. The opener just guides the motion. When a spring breaks, the opener is suddenly trying to move the full weight of the door on its own. which it usually can't do safely, and most modern openers will detect the resistance and stop.
This is why a broken spring isn't just an inconvenience. Operating a door with a failed spring puts stress on the opener motor, cables, and hardware. Don't keep trying to force it.
Why Springs Break. And Why Covina's Climate Plays a Role
Springs are rated for a set number of cycles. one cycle being one full open-and-close. Standard springs are rated for around 10,000 cycles, while higher-quality springs can reach 20,000 or more. If you use your garage door four times a day (twice in, twice out), a 10,000-cycle spring lasts roughly 7 years. That math alone explains why spring failures are so common.
But Covina's climate adds another variable. The San Gabriel Valley experiences significant temperature swings. hot, dry summers with highs near 90°F, and cooler winter nights where temperatures can dip into the mid-40s. The seasonal Santa Ana wind events strip humidity from the air, drying out metal components faster than they'd degrade in a more temperate coastal climate. Springs that aren't regularly lubricated become brittle faster under these conditions. That's why a well-lubricated spring in Covina can outlast a neglected one by years.
Many of the homes in Covina's established neighborhoods. the ranch-style houses near the Badillo area, the mid-century homes closer to Citrus Avenue. were built in the 1950s and 1960s and still have their original hardware setups. If you've never had spring work done and the house is more than 15 years old, there's a real possibility you're running on borrowed time even before anything snaps.
Torsion Springs vs. Extension Springs: What You Have Matters
Torsion springs sit horizontally above the door opening on a metal shaft. They store energy by twisting. Most newer and larger residential doors in Covina use this system. They're generally safer when they break because the coil stays on the shaft rather than flying loose.
Extension springs run along the horizontal tracks on each side of the door and stretch as the door closes. Older homes. and some lighter doors. still use this system. When an extension spring breaks, it can release with significant force. Properly installed extension spring systems have a safety cable threaded through the spring to contain it if it snaps. If yours doesn't have those cables, that's something to flag.
What Happens During a Spring Replacement
Spring replacement is one of the repairs that we strongly advise against DIY. Springs are under extreme tension. a torsion spring that's wound is storing a significant amount of energy, and releasing or winding it incorrectly can cause serious injury. This isn't a liability disclaimer; it's genuinely the most dangerous part of a residential garage door system.
A professional repair involves:
1. Safely releasing tension from the broken spring 2. Removing and measuring the old spring to match the exact wire size, inside diameter, and length needed for your door's weight 3. Installing the correct replacement. often a higher-cycle spring than the original 4. Checking cable condition. broken springs often coincide with worn cables, since both see the same stresses 5. Rebalancing the door and testing it manually before reconnecting the opener
Most spring replacements can be completed in under two hours. If you want to understand the broader scope of what a proper service visit covers, our frequently asked questions page has answers to what's typically included.
Should You Replace Both Springs at Once?
If you have a two-spring torsion setup (common on two-car garage doors), and one spring breaks, the other one is typically the same age and has the same number of cycles on it. Replacing both at the same time costs more upfront but usually saves money in the long run. you're already paying for the labor and service call, and the second spring is likely to follow within months or a year.
For single-spring systems, the question is simpler: you replace the one that failed and consider upgrading to a higher-cycle spring if you're in a higher-use household.
Other Repairs That Often Come With a Spring Failure
When a spring snaps suddenly, the door can drop unevenly and stress other components. After a spring replacement, it's worth having a technician check:
- Cables. look for fraying or uneven tension - Rollers. a dropped door can knock rollers off track - Bottom seal. repeated stress on the door can accelerate seal wear
If the opener has been working overtime trying to move a door with a failing spring, it may also have accumulated wear. For more on reading early warning signs before you get to an emergency repair, our post on warning signs you need garage door repair is worth a read.

Frequently Asked Questions
Q: How can I tell if my spring is broken before calling someone? A: Stand inside and look at the horizontal metal shaft above your door (for torsion springs). you'll often see a visible gap or separation in the coil. If the door goes up slightly and then the opener strains or reverses, that's also a strong indicator. A door that feels extremely heavy when you try to lift it manually is another sign.
Q: Can I still use my garage door with a broken spring? A: Technically the door may open partially with the opener, but you shouldn't. Operating the door puts dangerous stress on the cables, opener motor, and hardware, and the door can drop unexpectedly. Disconnect the opener and leave the door closed until the spring is replaced.
Q: How long does a spring replacement take, and how much does it cost? A: Most residential spring replacements take one to two hours. Costs vary based on spring type, size, and whether you're replacing one or both. Expect a higher price for high-cycle springs, which are worth the upgrade for most households.
