Your garage door has springs doing the heavy lifting. Most homeowners in Gilroy have either torsion springs or extension springs, and they work in completely different ways. Here's what you need to know: torsion springs twist to lift the door, while extension springs pull. A snapped spring means your door won't budge safely. We'll walk you through both types, why they fail, and what a fair estimate actually costs.
Torsion springs sit above your garage door, wound tightly on a metal shaft. When you open the door, they twist and gradually unwind, storing and releasing energy to counterbalance the door's weight. Think of it like winding a clock: the energy is stored, then released smoothly over time.
Most homes in Gilroy use torsion springs because they last longer, operate more smoothly, and handle heavier doors better than their counterparts. A quality torsion spring typically lasts 7 to 9 years with normal use, depending on how often you open and close the door. If you open your door 3 to 5 times daily, you're looking at the shorter end of that range.
The math is straightforward: each spring cycle counts as one complete opening and closing. A spring rated for 10,000 cycles will fail sooner if your family uses the garage constantly. That's just physics, not a manufacturing flaw.
Extension springs hang on both sides of your garage door opening, running along the horizontal tracks. Instead of twisting, they stretch and contract like a slinky. When the door goes up, they extend. When it closes, they contract back to their resting length.
Extension springs work fine for lighter doors but tend to wear faster than torsion springs. They're also more prone to sudden failure because they work under constant tension on both sides. A snapped extension spring on one side creates an imbalance that can damage your opener or cause the door to hang at an angle.
If you're experiencing uneven door movement or one side seems heavier than the other, a failed extension spring is often the culprit. Same-day service from Garage Door Gilroy can get you back in business before dinner time.
Age matters, but it's not the only factor. Lack of lubrication is huge. When springs don't get regular maintenance, rust and friction build up. The metal becomes brittle, and failure happens faster.
Weather in the Santa Clara Valley plays a role too. Hot summers and temperature swings stress metal. Humidity accelerates rust. If you've noticed your springs looking discolored or hear squeaking sounds, schedule service soon.

Heavy use wears springs faster than light use. If you run a business with a roll-up door or your household opens the garage 10+ times daily, expect springs to need replacement sooner. That's normal wear, not a defect.
A fair estimate for torsion spring replacement in Gilroy runs between $250 and $400 per spring, including labor. Extension springs typically cost $150 to $250 each. Most doors have one torsion spring or two extension springs, so budget accordingly.
Why the range? Spring quality varies. A heavy-duty commercial-grade spring costs more upfront but lasts longer and handles extreme use better. A standard residential spring is cheaper but may need replacement sooner if you have a heavier-than-average door.

If your springs need replacement, we'll explain exactly why and show you options that fit your budget and door type. Our previous post on garage door springs repair cost and replacement timing covers when to repair versus replace in detail.
Springs are dangerous. The tension stored in a wound torsion spring can cause serious injury if it releases unexpectedly. Extension springs can snap and strike you without warning. This isn't a job for the weekend.

How long do garage door springs last? Torsion springs typically last 7 to 9 years with normal residential use (3 to 5 cycles daily). Extension springs often fail sooner, around 5 to 7 years. Heavy use shortens lifespan. Regular lubrication and maintenance extend these timelines significantly.
Can I replace just one spring if I have two? Technically yes, but we don't recommend it. If you have two springs, both are the same age and stress level. When one fails, the other is close behind. Replacing both at once costs more upfront but saves a second service call and potential door damage in weeks.
What's the difference between a snapped spring and a worn spring? A snapped spring breaks suddenly, leaving the door unable to open safely. A worn spring still works but shows signs of rust, squeaking, or uneven door movement. Worn springs need replacement soon to prevent sudden failure and safety hazards.
Do extension springs need two replacements? Yes. Extension springs work in pairs on either side of the door. Both are under equal tension and wear at the same rate. Replacing only one creates imbalance and can damage your opener or door tracks over time.
How much does emergency spring service cost in Gilroy? Same-day or after-hours spring replacement runs $300 to $500 depending on spring type and time of call. Standard business-hours service costs $250 to $400. Call 669-257-8318 for an exact estimate based on your door and situation.
