Garage Door Spring Types in Burlingame: Torsion vs. Extension Explained
7 min read A2Z Garage Doors
If you've ever dealt with a stuck garage door, there's a good chance a worn or damaged spring is the culprit. Understanding what type of garage door springs in Burlingame you have is the first step toward getting the right repair. Most doors use either torsion springs or extension springs, and they work in very different ways.
What Are Garage Door Springs, and Why They Matter
Your garage door weighs 300 to 500 pounds. Springs counterbalance that weight, making it easy to open and close by hand or with an opener. Without healthy springs, your door either won't open at all or falls too fast. Springs last roughly 7 to 9 years under normal use. When one fails, you'll notice right away.
The two main types serve the same job but with different mechanics. Knowing which one powers your door helps you communicate clearly with repair pros and understand what goes wrong when springs fail.
Torsion Springs: The Heavy Lifter
Torsion springs sit above your garage door opening, mounted on a rod that runs across the garage. As the door opens, these springs twist and unwind, releasing stored energy. They store energy through tension, not stretch.
Torsion springs are the preferred choice for most modern garage doors. Here's why: they're more durable, quieter, and distribute the load more evenly. A single torsion spring can handle heavier doors. If one snaps, your door won't crash down as suddenly as with an extension spring failure.
The tradeoff is cost. Torsion springs run higher in price than extension springs, and installation requires specialized tools and knowledge. Never attempt this repair yourself. The tension is dangerous, and improper installation can damage your opener or worse.
Extension Springs: The Traditional Choice
Extension springs hang vertically on each side of the garage door opening. They extend and contract as your door moves up and down, storing energy through stretching. Older homes and lighter doors often use these.
Extension springs are cheaper upfront and simpler to install than torsion springs. However, they wear faster, create more noise, and wear unevenly. If one side's spring is older, it may fail before the other, putting unbalanced stress on your opener and door frame.
Safety cables run through the center of extension springs for good reason. If a spring snaps, the cable catches it and prevents the spring from flying across your garage.
Which Type Do You Have?
Look above your garage door opening. Torsion springs sit horizontally across the center, mounted on a rod. Extension springs hang vertically on either side. This visual check takes five seconds and saves confusion when you call for an estimate.

Spring Failure Signs and Next Steps
A snapped spring feels unmistakable. Your door either won't budge or drops suddenly. You might hear a loud bang or twang. Don't try to force it open. A broken spring means your opener is working twice as hard and will likely fail next.

Maintenance Extends Spring Life
Regular lubrication and inspection catch wear early. Springs operating smoothly last their full 7 to 9 years. Squeaking or grinding means friction is building. Uneven door movement suggests one spring is weakening.

Frequently Asked Questions
How long do garage door springs last? Torsion and extension springs typically last 7 to 9 years with normal use, roughly 10,000 cycles. Heavy use or poor maintenance shortens that lifespan. Springs don't fail gradually; they snap suddenly.
Can I replace a garage door spring myself? No. Spring replacement requires specialized tools and knowledge of high-tension mechanics. A snapped or incorrectly installed spring can injure you or damage property. Always hire a licensed technician.
What's the difference in cost between torsion and extension springs? Torsion springs usually cost 20 to 40 percent more than extension springs due to durability and installation complexity. However, they last longer and wear more evenly, offsetting the upfront cost.
Why is my garage door unbalanced? Unbalanced doors often signal uneven spring wear. One spring may be older or weaker than the other. This puts stress on your opener and door frame. Have both springs inspected and replaced together if one is failing.
Should I replace both springs even if only one snapped? Yes. Springs wear at similar rates. Replacing only one means the other will likely fail within months, costing you a second service call. Professional shops recommend replacing both at once for balance and peace of mind.
