Garage Door Spring Repair in Pasadena: Torsion vs. Extension Explained
2026-08-19 4 min read
If you've ever dealt with a stuck garage door, you know how frustrating it can be. Nine times out of ten, the culprit is a broken spring. But here's what most homeowners don't realize: not all garage door springs are created equal. In Pasadena, you'll find two main types under residential doors, and knowing the difference could save you hundreds on your repair bill.
The Two Spring Types: Torsion and Extension
Most homes in Pasadena use one of two spring systems. Torsion springs sit horizontally above the door opening and twist to lift the load. Extension springs hang vertically on either side of the door and stretch as the door lowers. Torsion springs are more common in newer construction and handle heavier doors with less wear. Extension springs are typically found in older homes and smaller, lighter doors. See our guide on garage door opener replacement cost in pasadena: skip the markup.
Here's the key difference: when a torsion spring snaps, your door becomes deadweight. When an extension spring breaks, safety cables keep the door from crashing, but you still can't operate it. Both require professional attention, but torsion failures demand faster response because of the safety risk.
Why Springs Fail (And How Long They Last)
Springs last roughly 7 to 9 years under normal use, assuming your door cycles about four to eight times daily. Pasadena's heat doesn't help. That Southern California sun accelerates metal fatigue, and springs that might last longer elsewhere wear faster here. Poor maintenance also speeds failure. If you're skipping lubrication, you're asking for trouble. Read about garage door springs in pasadena: when to replace and what it costs.
A snapped spring isn't always sudden. You might notice the door moving slower than usual, or hear a loud bang when it finally gives. That sound is the spring releasing all its tension at once. Once it breaks, don't try to open the door manually or with the opener. You risk injury, and you could damage the opener motor trying to force it.

When to Call a Professional (And Why DIY Is Risky)
I've been on trucks in Pasadena, and I've seen every DIY spring attempt end badly. Springs are under extreme tension. A single mistake can cause serious injury. Even if you know your way around tools, the equipment needed to safely remove and install springs isn't something you rent at the hardware store.
Professional repair takes about an hour and includes a safety inspection of the rest of your door system. We check the cables, rollers, and opener while we're at it. Many homeowners discover a second issue during that inspection, so addressing it upfront saves you a return trip. Our estimate is free, and we can schedule same-day service if you call early enough.

Cost and Timeline
Spring replacement typically costs between $200 and $400 per spring, depending on whether it's torsion or extension, and what size door you have. Most residential doors need two springs replaced as a pair, even if only one has snapped. This is because the second spring is nearly worn out too, and replacing one while the other is failing just means another service call in months.
We offer upfront pricing with no surprises. You'll know the cost before we touch anything. If you need a detailed breakdown of repair versus replacement costs, our garage door repair cost guide for Pasadena covers emergency and routine pricing side by side.

What Happens Next
After we install new springs, we test the door balance. A properly balanced door should stay open at any height when you open it manually. We also verify that safety cables are intact and that the opener isn't overworked. A complete inspection takes the same time as the repair, so we do it automatically.
Your door will feel brand new. Smooth operation, quieter movement, and the confidence that your family is safe. That's what we deliver every time.

Frequently Asked Questions
How do I know if my spring is broken? Listen for a loud bang or popping sound. The door will feel heavier than normal or won't open at all. You might see a gap in the spring coil or notice the door sagging on one side. Don't force the opener; call a professional immediately.
Can I replace one spring instead of two? Not recommended. Springs wear together. If one has failed, the other is near the end of its life. Replacing both at once costs less in labor and prevents a second emergency call within months.
How long does spring repair take? Most replacements take 45 minutes to an hour from start to finish, including balance testing and safety inspection. We can fit same-day appointments for calls before noon on weekdays.
Are torsion springs better than extension springs? Torsion springs handle wear better and are safer if they fail because safety cables aren't required. They're more expensive upfront but often last longer and work better on heavier doors. Extension springs are fine for lighter doors and older homes.
