Garage Door Springs in South Pasadena: Types, Cost & When to Replace

2026-06-05 7 min read

Garage door springs are the hardest working component in your home, and they fail silently. A snapped spring won't stop your door from moving, but it will stop it from opening safely. The two main types are torsion springs (mounted above the door) and extension springs (mounted on the sides). Understanding which type you have, how long they last, and what replacement costs is the difference between a safe garage and a liability.

Two Types of Springs: Know Your Enemy

Torsion springs are the premium option. They wind tightly around a metal rod above your garage door opening and unwind to lift the door. Most modern South Pasadena homes use these because they're more durable, quieter, and safer when failure happens. Torsion springs last 7 to 9 years with average use (roughly 10,000 cycles).

Extension springs do the opposite. They hang on either side of the door and stretch as the door closes, then contract to help lift it. These are cheaper upfront but fail more spectacularly because the spring snaps outward with tremendous force. Extension springs typically last 5 to 7 years and are more common in older homes or budget installations.

A single spring failure might not feel urgent. Your opener may still pull the door up partway. Don't ignore this. A broken spring puts all the load on your opener motor, which will burn out within weeks. More importantly, a door without functioning springs can fall suddenly, trapping a car, pet, or person underneath. I've seen garage door accidents that changed families forever.

Warning Signs of Spring Failure

Listen for a loud bang or crack in your garage. That's often a spring snapping under tension. You might also notice the door opening slower than normal, or the door hanging unevenly (one side higher than the other). Some homeowners see visible rust or corrosion on the springs or hear a creaking sound when the door moves.

If you spot these signs, stop using the garage door immediately and call a professional. Don't attempt to manually lift the door or test the opener. A broken spring under tension can release suddenly and cause serious injury. We recommend a free estimate call to Garage Door South Pasadena so you know exactly what you're facing.

Cost and Timeline for Replacement

Spring replacement cost varies based on spring type and your garage setup. Torsion spring replacement typically runs $200 to $400 per spring, while extension springs cost $100 to $200 each. Most doors have one or two springs, so total cost usually falls between $250 and $600 for parts and labor.

The best time to replace springs is before they fail. If one spring is nearing the end of its life cycle, the other is close behind. Many technicians recommend replacing both springs at the same time, even if only one has snapped. This keeps your door balanced and prevents a second failure weeks later.

Our team can provide an accurate cost estimate once we inspect your setup. Spring quality varies too. Heavy-duty commercial-grade springs cost more but outlast budget options. For details on our spring repair and replacement services, visit our service page.

If you're also upgrading your garage door system, springs work hand-in-hand with your opener. I've written about choosing the right garage door opener in South Pasadena if that's on your agenda.

Why DIY Spring Replacement Is Dangerous

The internet is full of DIY spring replacement videos. Don't watch them. Springs are under extreme tension, and releasing that tension without the right equipment and training can cause serious injury. A torsion spring can snap back and break bones or cause lacerations. Extension springs can shoot across the garage like projectiles.

Professional technicians use specialized winding tools and safety cables to manage tension safely. We've also seen homeowners accidentally damage the garage door, the opener, or the frame while attempting repairs. A professional replacement takes 1 to 2 hours and comes with a warranty. A DIY attempt often costs more to fix than hiring us from the start.
