A customer called last Tuesday morning. Her garage door had jammed halfway up, and she'd watched a YouTube video about spring replacement. She had a socket set, confidence, and zero understanding of the 300 pounds of tension coiled in that metal rod above her head. Twenty minutes into the job, she called us instead. That decision kept her out of the emergency room.
Garage door springs in Sausalito fail every single day. Most homeowners don't know the difference between a torsion spring and an extension spring, and that knowledge gap has sent people to hospitals with crushed hands, severed fingers, and facial lacerations. This post explains what you're actually dealing with, why DIY replacement is a genuine safety hazard, and when to call a professional instead.
Your garage door likely uses one of two spring types. Torsion springs sit horizontally above your door, wound tightly like a twisted rope. When the door closes, these springs store rotational energy. Extension springs run vertically on each side of the door frame, stretching and contracting like rubber bands as the door moves up and down.
Here's what matters: torsion springs carry vastly more tension. A single torsion spring on a standard residential door stores roughly 10,000 to 15,000 foot-pounds of energy. Extension springs store 3,000 to 5,000 each. That's not academic. It's the difference between a minor injury and a life-altering one.
When a torsion spring snaps, it releases all that energy in milliseconds. Homeowners have reported the spring coil whipping across the garage, denting the door, cracking windows, or striking whoever happened to be nearby. Extension springs fail differently, but just as dangerously. A snapped extension spring means the door loses support on one side and can slam down unevenly, jamming rollers, bending tracks, or crushing anything underneath.
I've been in this industry long enough to see the pattern. Homeowners think they're saving money on the estimate cost. Then a spring snaps during installation. Emergency room visit. Infection risk. Lost wages. The initial "savings" evaporate fast.
Professional technicians use specialized tools: spring hooks, winding bars, safety cables, and torque-adjusted equipment. We've spent years learning to read spring tension by sound and feel. We know how to safely relieve tension before unwinding a spring, and we understand the exact sequence needed to prevent catastrophic failure.
If you're tempted to save a few hundred dollars, read what happened to homeowners in the Bay Area over the past year. One person in Marin County attempted extension spring replacement and caught three fingers in the snapped coil. Another in San Francisco thought they'd tackle torsion spring installation and the door fell on their shoulder, resulting in a rotator cuff tear.
You can inspect your springs safely from a distance. You should never attempt to remove, wind, or replace them yourself.

How long do garage door springs last? Most springs last 7 to 9 years with normal use (400 to 500 cycles monthly). Factors like climate, humidity, and door frequency affect lifespan. Springs don't wear out gradually; they fail suddenly without warning.
Can I replace just one spring if the other is fine? No. Springs work as a pair. If one fails, the other is near the end of its life too. Replacing both ensures balanced door operation and prevents a second emergency repair within months.
What does a snapped spring sound like? A loud bang or crack, like a gunshot or firework. The sound comes from the sudden release of thousands of pounds of tension. If you hear this, don't open your door and call a professional immediately.
Why is professional spring replacement so expensive? Springs carry extreme tension requiring specialized tools and training. Technicians carry liability insurance because the work is genuinely dangerous. You're paying for safety, expertise, and the guarantee that your door works correctly afterward.
How do I know if I need torsion or extension springs? Look above your garage door. Torsion springs sit horizontally on a shaft. Extension springs hang vertically on each side. We can identify which type you need during a free estimate call.
