Here's what most homeowners don't realize about garage door springs: they don't fail randomly. Springs wear out on a predictable schedule, typically lasting 7 to 9 years with regular use. Understanding whether your door uses torsion or extension springs, and recognizing early warning signs, helps you avoid a snapped spring at the worst possible moment.
Your garage door almost certainly uses one of two spring systems. Torsion springs sit above the door opening on a horizontal rod. They twist and unwind to lift the heavy door panels. Extension springs hang from the sides of the door frame and stretch to provide lift.
Torsion springs are the stronger, more durable choice. They handle the load more efficiently and last longer with fewer safety concerns. Extension springs work well for lighter doors or narrower openings, but they require safety cables to catch them if they snap.
Most San Mateo homes built in the last 20 years use torsion springs. If you're unsure which type you have, look above your door opening. A horizontal rod with a large wound coil? Torsion. Vertical springs on either side that stretch? Extension.
Springs fail because metal fatigues. Every time your door opens and closes, the spring cycles. A typical household door cycles roughly 1,500 times per year. After 10,000 to 15,000 cycles, the metal loses its ability to hold tension.
Climate matters too. The San Mateo Bay Area's temperature swings, salt air from nearby coastal regions, and humidity all accelerate wear. Cold weather makes springs brittle. Heat makes metal more flexible than it should be.
When a torsion spring snaps, your door becomes unmovable. The opener cannot lift a 300 to 500 pound door without spring support. An extension spring failure is equally problematic and potentially hazardous because the door loses all upward force suddenly.

A snapped spring is unmistakable: your door won't open. But problems start earlier. Listen for creaking or popping sounds when the door moves. Watch for the door rising unevenly, tilting to one side, or moving more slowly than normal. These signs mean one spring is weakening while the other still works.
Some homeowners notice the door feels heavier when operating the wall button. Others hear grinding noises from the opener working harder to compensate.
If your garage door won't open at all, don't force it. Forcing a door with a broken spring risks damaging the opener, tracks, and panels. A professional inspection costs far less than emergency replacement. Our team at Garage Door San Mateo can assess your system and provide a same-day estimate if springs need replacement.
Spring replacement cost typically ranges from $250 to $600 per spring, depending on spring type, size, and door weight. Torsion springs cost more than extension springs, but they're worth it for durability and safety.
If your door is 8 years old or older, consider replacing both springs at once, even if only one failed. The second spring is likely close behind. Replacing both springs at the same time costs less than two separate service calls and prevents a second failure weeks later.

How long do garage door springs last? Most garage door springs last 7 to 9 years under normal household use, cycling roughly 1,500 times per year. Factors like climate, door weight, and maintenance affect lifespan. Springs in the San Mateo area may wear faster due to coastal salt air and temperature swings.
Can I replace a garage door spring myself? Spring replacement requires specialized tools and knowledge of high-tension systems. Improper installation risks serious injury. Professional technicians have the safety equipment and experience to replace springs correctly. DIY attempts often result in damage or harm.
What's the difference between torsion and extension springs? Torsion springs sit horizontally above the door and twist to lift it. Extension springs hang vertically on the sides and stretch for lift. Torsion springs are stronger, last longer, and are safer. Most modern doors use torsion springs.
Should I replace both springs if only one breaks? Yes, replace both springs together. If one spring failed after 8 years of use, the second spring is likely near failure too. Replacing both at once prevents a second emergency and costs less than two separate service calls.
