Garage door springs in Belmont break without warning, and most homeowners don't know which type they have or what repair actually costs. The two main types, torsion and extension springs, work differently and fail differently. Understanding this difference saves you money and keeps you safe when something goes wrong.
Springs do the heavy lifting. Your garage door weighs 300 to 500 pounds. Without springs, your opener would burn out in weeks. Torsion springs sit above the door on a horizontal rod and twist as the door moves. Extension springs hang on each side and stretch like rubber bands. Both types last roughly 7 to 9 years with normal use, depending on how many times you open and close the door each day.
A snapped spring isn't just inconvenient. It's a safety hazard. The door becomes unbalanced and can drop without warning. Metal parts whip through the air when springs fail. This isn't a "wait and see" repair.
Torsion springs are stronger and more durable. They're also more expensive, typically $150 to $300 per spring in Belmont. Most newer homes have torsion springs because they last longer and distribute force evenly. The repair is cleaner, and the door operates more smoothly.
Extension springs cost less upfront, around $75 to $150 each, but wear out faster. They're common in older homes and garages with limited headroom. If one breaks, the other usually follows within months because they've been sharing the load. You'll likely replace both at the same time, doubling your cost.
Installation difficulty matters too. Torsion spring replacement requires special tools and skill. Extension springs are easier but still dangerous if you don't know what you're doing. Garage door maintenance in Belmont with a spring tune-up can catch wear before failure and save you from emergency calls.

Spring replacement isn't just the part. Labor, travel time, and emergency pricing add up fast. A same-day call on a Saturday? Expect a service fee on top of parts. In Belmont and nearby Redwood City, basic spring replacement runs $200 to $400 per spring with labor included. If both springs fail, you're looking at $400 to $800 total.
The good news: regular maintenance prevents most failures. When you know your springs are wearing out, you can schedule at your convenience instead of panicking when the door won't budge. Our garage door repair troubleshooting guide shows you what to check before calling, so you can describe the problem accurately and avoid unnecessary fees.
Your garage door should move smoothly and quietly. If the door jerks, creaks, or feels heavier than usual, springs are likely losing tension. Listen for a loud bang or snap. That's a spring breaking under load. After it breaks, the door won't open without the opener working twice as hard.
A simple test: pull the emergency release cord and try to lift the door manually. It should feel reasonably light. If it's suddenly heavy, springs are weakening or already damaged. Don't keep using the door. Pressure on the opener accelerates wear on cables and other parts.

You don't have to wait for failure. Most homeowners spend $150 to $250 on preventive spring inspection and lubrication once a year. Compared to a $600 emergency repair at midnight, that's money well spent. Belmont winters bring moisture that accelerates rust and corrosion on metal springs, especially near the coast where salt air is present.
If springs are nearing the end of their life, replace them on your schedule, not the springs' schedule. A proactive call saves stress, money, and the risk of being stranded when you need your garage door most.

How long do garage door springs actually last? Torsion and extension springs typically last 7 to 9 years with average use (one to two open/close cycles per day). Frequent use, moisture, and lack of lubrication shorten that window. A professional inspection can tell you where yours stand.
Can I replace just one spring? Not recommended. If one spring fails, the other is near the end too. Replacing both at the same time costs less than a return visit in a few months and keeps the door balanced and safe.
What's the difference between a snapped spring and normal wear? Normal wear makes the door feel heavier and the opener work harder over weeks. A snapped spring happens suddenly, often with a loud bang, and the door becomes impossible to lift manually or may drop on its own.
Is garage door spring repair something I can DIY? No. Springs are under extreme tension and can cause serious injury if mishandled. Even experienced homeowners should call a professional. The cost of a mistake far exceeds the repair price.
Will my homeowner's insurance cover spring replacement? Most policies don't cover springs because they're considered normal wear and tear. Call your agent to confirm, but budget for this repair out of pocket in most cases.
