A customer called last Tuesday afternoon. Her garage door hung crooked, wouldn't budge, and she heard a loud bang that morning. Within minutes of troubleshooting over the phone, I knew the truth: a torsion spring had snapped. She'd been minutes away from opening that door manually, which could have sent 400 pounds of metal and glass crashing down. Garage door springs in Burlingame fail silently and without warning. This guide explains what you need to know before yours does.
Your garage door weighs between 300 and 500 pounds depending on material and size. That weight doesn't stay suspended by magic. Two springs, either torsion or extension type, counterbalance the entire load every single time you open or close. Torsion springs wind and unwind under extreme tension. Extension springs stretch and contract. Both work in pairs. When one fails, the other cannot handle the full weight alone. The door becomes a safety hazard instantly.
Springs don't last forever. Most last 7 to 9 years with average use (about 10,000 cycles per spring). Coastal Burlingame weather, with salt air and humidity, accelerates rust and corrosion, shortening that lifespan. If your door is older than seven years and you haven't replaced the springs yet, you're playing with fire.
A snapped spring creates an obvious symptom: the door won't open, or it opens unevenly and gets stuck partway. But the real danger is catching the warning signs before failure happens.
Listen for a loud bang or crack sound when operating the door. That's often the spring failing under load. Look for visible rust or gaps in the spring coils. If one spring looks discolored or pitted compared to the other, corrosion is eating through the metal. The door might feel heavier to lift manually. It might jerk or hesitate when opening. Any of these red flags means professional inspection is overdue.

I've seen homeowners attempt spring replacement with online tutorials and rented equipment. Every single one I've treated afterward wished they hadn't. Torsion springs operate under 200 to 400 pounds of tension. A slipped tool, miscalculation, or sudden release can cause serious injury. Springs can snap midway through installation. The door can fall without warning. This isn't like changing a car tire.
Extension springs have a secondary danger: broken safety cables. If an extension spring snaps, the cable should catch it and prevent it from whipping across the garage. But if you're replacing springs and don't reinstall cables correctly, you've created a projectile hazard. A failing extension spring can travel at 60 miles per hour.
Professional technicians have the proper winding tools, safety cones, and insurance. We know the exact tension needed for your specific door weight and spring type. We test the door after replacement to ensure both springs are balanced.

How do I know if my garage door spring is bad? Listen for loud bangs or cracks. Look for visible rust, gaps in the coils, or uneven door movement. The door may hang crooked or feel heavier when you try to open it manually. Any of these signs warrant a professional inspection immediately.
Can I open my garage door if a spring is broken? No. Attempting to open a door with a broken spring can cause the door to crash down suddenly, trapping vehicles or causing injury. Call a professional before attempting anything.
How much does a garage door spring replacement cost near me? Spring replacement in Burlingame typically costs $250 to $600, including labor and parts. The exact estimate depends on spring type, door size, and any secondary damage. We offer free estimates before any work begins.
How long do garage door springs last? Most springs last 7 to 9 years with normal use. Coastal environments like Burlingame see faster wear due to salt and humidity. Regular maintenance can extend lifespan slightly but won't prevent eventual failure.
What's the difference between torsion and extension springs? Torsion springs wind above the door and handle heavier loads more smoothly. Extension springs stretch along the sides and suit lighter doors. Both fail eventually and both require professional replacement for safety reasons.
