It happens fast. You hit the button on your opener, hear a loud bang. sometimes described as a gunshot. and the door either doesn't move at all or creeps up a few inches and stops. If this just happened to you, there's a very good chance a garage door spring has broken.
Broken springs are the single most common reason a garage door in San Jose won't open. Understanding what actually broke, why it happened, and what comes next can save you from making expensive mistakes. or getting hurt.
Your garage door is heavy. A standard two-car steel door weighs between 150 and 250 pounds. The spring system. not the opener motor. is what actually does the heavy lifting. The opener is just a mechanism to trigger the movement; the springs counterbalance the door's weight so the motor doesn't have to strain.
There are two main types of spring systems you'll find on San Jose homes:
- Torsion springs are mounted horizontally above the door opening, attached to a metal tube. They twist and unwind to raise and lower the door. Most homes built in the 1990s and later. including the newer construction in neighborhoods like Silver Creek Valley, Blossom Valley, and Evergreen. use torsion spring systems. - Extension springs run horizontally along the tracks on either side of the door and stretch to create tension. These are more common on older homes and one-piece doors, and you'll see them on plenty of properties in established neighborhoods like Rose Garden and parts of Willow Glen.
When either type breaks, the door becomes essentially dead weight that your opener cannot move on its own.
Springs don't last forever. they're rated by cycle count, typically 10,000 cycles for standard springs (one cycle = one open and one close). For a household that uses the garage twice a day, that's roughly 13,14 years of service life. Higher-cycle springs rated at 20,000 or 30,000 cycles are available and worth asking about when replacing.
San Jose's climate plays a role too. The city's wet season. running November through March. brings moisture that settles on spring coils overnight, especially in areas prone to radiation fog like Almaden Valley and the Coyote Creek corridor. Without regular lubrication, that moisture leads to surface rust, which weakens coil integrity and accelerates failure. A spring that might have lasted 15 years with proper care can fail at 10 if it's been neglected.
Most garage doors have two springs installed at the same time, so when one breaks, the second spring's life expectancy is likely nearly expired as well. That's why most professional technicians recommend replacing both springs simultaneously. doing otherwise often means a second service call within months.
This is important: do not attempt to repair or replace garage door springs yourself.
Springs store enormous amounts of mechanical energy under high tension. A loaded spring that releases suddenly can cause severe lacerations, broken bones, or worse. The tools required. winding bars, cable drums, proper spring sizing by door weight. are specialized. Using the wrong spring size for your door's weight can damage the opener, cause imbalanced operation, and create a dangerous situation for your family.
If your spring has broken and your car is trapped inside, you *can* manually disengage the opener (pull the red emergency cord) and lift the door by hand with a helper. but do this carefully and only partway, enough to drive out. Don't prop the door open with a broken spring system unattended.
A professional technician will measure your door's height, width, and weight to determine the correct spring specifications. This matters more than most homeowners realize. installing the wrong spring leads to premature failure and added strain on your opener motor.
For most standard residential doors in San Jose, broken spring repair is a same-day job. A technician arrives, confirms the failure, removes the old spring(s), installs correctly sized replacements, adjusts tension, re-connects the opener, and tests the door's balance. The whole process typically takes 45 minutes to 90 minutes for a straightforward torsion spring replacement on a standard two-car door.
If your home in Campbell or elsewhere in the South Bay has an older extension spring system, the process is similar but may involve replacing the safety cables that run through the springs as well. those cables are a critical safety backup if a spring snaps.

Be realistic about pricing. Spring replacement is one of the more straightforward garage door repairs, but parts and labor costs vary based on spring type, door size, and whether you're replacing one or both springs. High-cycle springs cost more upfront but offer better long-term value for a busy household. Get a clear, itemized quote before work begins. any reputable company will provide one.
If a technician quotes you a price over the phone without asking about your door's size, weight, or spring type, that's a yellow flag. Proper pricing requires knowing the specifics of your system.
Once your springs are replaced, a few habits will extend their lifespan significantly:
1. Lubricate the spring coils with a garage door lubricant every six months. especially before the rainy season when moisture is more prevalent. 2. Do the balance test periodically: disconnect the opener and see if the door holds at waist height when released manually. 3. Ask for high-cycle springs when replacing. the upgrade cost is modest and the extra lifespan is worth it for a busy household.

Can I still open my garage door manually with a broken spring? Technically yes, but it requires significant effort because the door has no counterbalance. A standard two-car door can weigh 200 pounds or more without spring assistance. You can disengage the opener with the emergency release cord and lift with a helper to retrieve your vehicle, but don't leave the door propped open unattended. it's a safety hazard.
How long does a garage door spring repair take? For most standard San Jose homes, a torsion spring replacement is completed in under 90 minutes. Technicians typically carry common spring sizes on their service vehicles, so same-day completion is the norm rather than the exception.
Should I replace one spring or both at the same time? Both. If one spring has reached the end of its service life, the second one is right behind it. Replacing both at the same time saves you a second service call fee within a few months and keeps your door operating in balance, which protects your opener motor from unnecessary strain.
