When your garage door won't open and you hear a loud twang from above, you're probably looking at a spring problem. The question isn't always whether you need a new spring. Sometimes repair works. Other times replacement is smarter for your wallet. Here's how to tell the difference and avoid paying for the wrong fix.
Garage doors use two main spring styles: torsion springs and extension springs. Torsion springs wind around a rod above your door and store energy by twisting. Extension springs sit on either side of the door and stretch to pull it open. Each type fails differently and costs differently to repair.
A snapped torsion spring is almost always a replacement situation. These springs are under extreme tension. Attempting a partial repair risks injury and typically fails within months. Extension springs sometimes wear unevenly, meaning one side breaks before the other. In rare cases, you can replace just one side, but most pros recommend replacing both at once since the working spring is likely near the end of its lifespan anyway.
Springs last 7 to 9 years with normal use, sometimes longer. If your door is 8 years old and one spring fails, the other is probably close behind. Single replacement now means another service call and cost soon. That's why Garage Door San Anselmo techs usually recommend addressing both springs at once.
True spring repair is uncommon in San Anselmo and most areas. What's sometimes called a "repair" is really a temporary adjustment. A technician might re-tension an extension spring or adjust the door's balance. These fixes buy you a few weeks or months, but they're not permanent solutions.
Repair only makes financial sense if your springs are relatively new (under 4 years old) and the issue is a loose connection or fastener rather than a break. If you notice your door closing unevenly or opening slowly, call for an estimate before assuming replacement is needed. Sometimes a simple tune-up resolves the problem affordably. For guidance on preventive care, see our garage door maintenance tune-up guide for San Anselmo homeowners.
Replacement is almost always the smarter call when a spring snaps or shows serious wear. A snapped spring means immediate loss of function. Your opener can't lift the door safely without it. Driving the opener with a broken spring burns out the motor fast, turning a $300 spring problem into a $600 opener problem.
Replacement typically costs between $250 and $450 for parts and labor in the San Anselmo area, depending on spring type and your door's weight. Torsion springs cost more than extension springs. Heavier doors need stronger springs. Labor usually runs $150 to $200 because the job requires specialty tools and skill.

Don't trust a phone quote for spring work. Every garage door is different. Spring cost depends on your door's size, weight, and spring type. A technician needs to see your setup in person to give a real estimate. Many companies offer free estimates, including Garage Door San Anselmo, so use that advantage.
When comparing quotes, ask if the estimate includes both springs or just one. Ask about the spring brand and warranty. Quality springs carry 5 to 10 year warranties and cost a bit more upfront but last longer. Cheaper springs might fail sooner, erasing your savings. For context on typical garage door expenses, our garage door cost and pricing guide breaks down where money actually goes.
Springs are under thousands of pounds of tension. A slip costs lives. Serious injury happens every year from DIY spring work. The risk far outweighs savings of a few dollars. Always hire a licensed pro. Beyond safety, improper installation voids warranties and causes alignment problems that damage your door and opener.

A snapped spring is obvious: your door won't move. Wear signs are subtler. If your door opens slowly, closes unevenly, or makes creaking sounds during operation, don't wait. Weak springs force your opener to work harder, shortening its life. Early replacement prevents more expensive repairs later.

The bottom line: repair rarely solves a broken spring. Replacement is almost always the real answer. Get a professional estimate, compare quotes, and handle it promptly. Your garage door will be more reliable, and you'll avoid overpaying for incomplete fixes.
How long do garage door springs last? Torsion and extension springs typically last 7 to 9 years with standard residential use. Lifespan depends on how often you use your door, climate, and maintenance. Springs in humid regions like the Bay Area may wear faster due to rust.
Can I replace one spring instead of both? Technically yes, but it's not recommended. Both springs share the load equally. If one is worn enough to break, the other is likely near failure too. Replacing both now saves you another service call in a few months and reduces total cost.
What's the average cost of spring replacement in San Anselmo? Expect $250 to $450 total, including labor and parts. Torsion springs cost more than extension springs. Heavy doors need stronger springs. Get a site estimate for your specific door weight and type.
Is spring repair cheaper than replacement? True repair is rarely possible for broken springs. Adjustments might temporarily improve performance but won't fix a snapped spring. Replacement is the permanent solution and often costs less than repeated repair attempts.
Should I replace springs before they break? If your door is 8 or 9 years old and springs are original, proactive replacement makes sense. It prevents emergency breakdowns and often costs less than emergency service. Ask your technician for a condition assessment during routine maintenance.
