If you've ever heard a loud bang from your garage. like a gunshot. and then found your door won't budge, there's a good chance a spring just let go. It's one of the most common garage door problems we see in San Ramon, and one of the most misunderstood. Here's what you actually need to know.
San Ramon's climate is generally forgiving. mild winters, dry summers, and temperatures that rarely drop below freezing. But don't let that lull you into complacency about your garage door springs. The real wear comes not from cold snaps but from cycle fatigue: every time your door opens and closes, the springs wind and unwind. A typical torsion spring is rated for about 10,000 cycles. For a family using their garage as the primary entrance. common in Dougherty Valley and Gale Ranch homes. that can mean 4 to 6 opens per day, which adds up to worn-out springs in as little as 5 to 7 years.
There's also the issue of builder-grade hardware. Many of the homes built by Shapell Industries and later Toll Brothers in San Ramon's master-planned communities were equipped with standard-cycle springs that weren't designed for heavy, long-term use. If your home was built between the 1990s and mid-2000s and you've never replaced your springs, they may be well past their prime.
Most San Ramon homes. especially the 2, 3, and 4-car garages common in Gale Ranch and Canyon Lakes. use torsion springs, which are mounted horizontally above the door opening on a steel shaft. These are the preferred type for larger, heavier doors because they provide balanced lifting force and last longer than the alternative.
Extension springs are less common in newer construction. They run along the horizontal tracks on either side of the door and work by stretching. You'll find them more often on older, smaller single-car garage doors. If one extension spring breaks, the door can slam down unevenly, which is a safety hazard.

You don't always get the dramatic bang. Sometimes springs wear down gradually. Watch for these warning signs:
- The door is heavy to lift manually. A properly functioning spring system should let you lift the door with one hand to about waist height when disconnected from the opener. If it feels like dead weight, the springs are losing tension. - The door opens a few inches, then stops. Your opener is straining against a weakening spring and may be triggering the auto-reverse safety feature. - Visible gaps or separation in the spring. A broken torsion spring often separates, leaving a visible gap in the coil. - The door closes faster than usual. Springs counterbalance the door's weight. When they lose tension, the door drops more quickly. which is dangerous. - Loud squeaking or grinding during operation. This can indicate a spring that's corroding or nearing the end of its life.

We understand the instinct to save money, especially when you can watch a YouTube video and order parts online. But garage door spring replacement is genuinely dangerous for untrained homeowners. Torsion springs are under extreme tension. enough to cause severe injury if they release unexpectedly during removal. This isn't a scare tactic. A loaded spring can snap a wrist or cause serious eye injury in a fraction of a second.
Beyond the safety issue, springs have to be matched precisely to the door's weight and size. The 3-car garage doors on many Gale Ranch homes are significantly heavier than standard residential doors. Installing the wrong spring. even slightly. leads to premature failure, uneven lifting, and added stress on your opener motor.
Professional technicians have the tools to measure door weight and install the correct spring size. It's one of the few garage door jobs where the "call a pro" advice isn't just about liability. it's about your safety.
For most San Ramon homeowners, expect to pay in the range of $200,$400+ for a standard spring replacement, including labor. Larger or heavier doors. the kind with oversized openings you'll find in some Dougherty Valley custom homes. may cost more due to the specialized spring sizing required. Most reputable companies will replace springs in pairs even if only one has broken, because if one spring has reached its lifespan, the other is typically close behind.
When you're comparing quotes, ask whether the price includes both springs, what cycle rating the replacement springs carry, and whether the technician will also check cable condition. Cables work in tandem with springs and often show wear at the same time.
Reach out to schedule a same-day inspection if you're seeing any of the warning signs above. catching a spring before it fully breaks saves you the hassle of a door that won't move at all.
Once your springs are replaced, ask the technician to check the full system balance. A properly balanced door should stay in place when raised to halfway. it shouldn't drift up or fall down on its own. If it does, the spring tension needs adjustment.
It's also a good time to lubricate the new springs (if they're non-lubricated steel), inspect rollers, and test the auto-reverse function on your opener. Think of spring replacement as a natural checkpoint for the whole system.
Most standard springs are rated for 10,000 cycles. In a typical household using the garage as a main entrance 4,6 times per day, that works out to roughly 5,7 years. Upgrading to high-cycle springs (rated for 25,000+ cycles) at the time of replacement is often worth the added cost for busy families.
Technically, the opener may still try to move the door, but it puts enormous strain on the opener motor and the door itself. More importantly, a door with a broken spring can drop suddenly and without warning. We strongly recommend not using the door until the spring is replaced.
If your door has two torsion springs (common on wider doors), yes. it's standard practice to replace both simultaneously. They wear at the same rate, so if one breaks, the other is likely close to failure. Replacing both at once saves you a second service call and keeps the door balanced.
