Your garage door works quietly every day until it stops. A snapped spring is usually the culprit. The good news: spring replacement is straightforward and predictable. In San Anselmo, most homeowners pay between $300 and $600 per spring, depending on type and whether you need one or both replaced at the same time.
Garage door springs are under constant tension. They counterbalance your door's weight, making it easy to open and close. Over time, that tension takes a toll. Most residential springs last 7 to 9 years with average use. If you use your garage door 4 to 8 times daily, you're looking at the shorter end of that range. See our guide: Garage Door Springs in San Anselmo.
Two main types exist: torsion springs (mounted horizontally above the door) and extension springs (mounted vertically on each side). Torsion springs are more common in modern homes and tend to fail less frequently, but replacement costs slightly more. Extension springs are cheaper to replace but wear out faster because they work independently.
A single spring replacement typically runs $300 to $500 in the San Anselmo area. If both springs have failed or are nearing failure, you'll pay $600 to $1,000 for the pair. Labor makes up roughly half that cost; the parts themselves are the other half. See our guide: Garage Door Springs in San Anselmo.
Why the range? Material quality, spring size, and local labor rates all factor in. Heavier doors need stronger springs. A small residential door costs less than a commercial or oversized residential installation. If your garage door opener needs adjustment after spring replacement, expect an additional $75 to $150.

Spring replacement looks simple online. It's not. These springs are under extreme tension and can cause serious injury if handled incorrectly. A snapped spring can fly across your garage or cause the door to fall suddenly, crushing hands, feet, or anything beneath it.
Professional technicians have the tools, training, and insurance to do this safely. If something goes wrong three months later, you're covered. DIY means you're liable for damage and injuries. The cost difference between DIY and professional service is small compared to a hospital visit or property damage.

If one spring has failed, should you replace both? Many technicians recommend replacing both at the same time, even if only one is broken. Here's the logic: if one spring is at the end of its life, the other isn't far behind. Replacing both now means you avoid a second service call and downtime a few months later.
However, if your springs are relatively new (under 5 years old) and only one failed due to a manufacturing defect, replacing just the broken one is reasonable. Ask your technician for their assessment. For more on this decision, check our guide comparing garage door spring repair versus replacement options.
Shop around. Get estimates from at least two local providers. Prices vary, and some companies charge more for convenience (evenings, weekends) than others. If you need same-day service, expect to pay a premium.
Ask what's included. Does the estimate cover removal of the old spring, installation of the new one, and door balance testing? Some shops bundle these; others charge separately. A complete estimate should list each service and its cost.
Check for manufacturer warranties on the springs themselves. Most quality springs come. This protects you if a spring fails prematurely. Your technician should transfer that warranty to you after installation.
Consider scheduling routine maintenance. A yearly inspection costs far less than emergency spring replacement. During a tune-up, a technician can spot wear before failure happens and replace springs on your schedule, not the spring's. Explore our garage door maintenance guide to learn what homeowners often miss.

The longer you wait with a broken spring, the more stress you put on your opener and other components. A small repair now prevents a larger bill later.
How do I know if my garage door spring is broken? The door won't open, feels heavier than normal, or makes a loud snapping noise. You may also see the spring visibly separated or sagging. Never try to force the door open; call for professional help immediately.
Can I still use my garage door if one spring is broken? No. An opener isn't designed to lift the full weight alone. Attempting to open the door stresses the motor and can cause additional damage. Stop using it and call a technician.
How long does spring replacement take? Typically one to two hours, depending on the spring type and your door's configuration. A technician should test the door's balance and function before leaving.
Do garage door springs come with a warranty? Most quality springs include a limited lifetime warranty against manufacturing defects. Your technician should provide warranty documentation after installation. Residential use is usually covered; commercial use may void it.
What's the difference between torsion and extension springs? Torsion springs mount horizontally above the door and twist to support the weight. Extension springs mount vertically on each side and stretch. Torsion springs are more durable and safer but cost slightly more to replace.
