Let's cut through the confusion about garage door springs. Your garage door weighs 300 to 500 pounds. Two metal springs hold that weight in balance, lower it safely, and lift it back up thousands of times. When one snaps, your door won't budge. Here's what you need to know about the two main types and when to call for help near you.
Torsion springs live above your garage door, centered on a metal rod. They twist and unwind to handle the load. Most modern homes in Menlo Park use torsion springs because they last longer, operate more smoothly, and take up less space than extension springs.
A quality torsion spring lasts 7 to 10 years with average use. That's roughly 10,000 to 15,000 cycles (one cycle equals opening and closing). When a torsion spring snaps, you hear a loud bang. The door becomes immovable because the spring's tension is gone. Replacing torsion springs requires special tools and real expertise. This is not a DIY job. The spring is wound under extreme tension and can cause serious injury.
Extension springs run horizontally along the sides of your door frame. They stretch and contract like a rubber band. Older homes and some newer installations use extension springs, though torsion dominates the market today.
Extension springs fail faster than torsion springs, typically lasting 5 to 8 years. They're also harder on your garage door opener because they don't distribute weight as evenly. When an extension spring snaps, the door becomes unbalanced and can bind or jam. Safety cables run through extension springs to catch a broken spring before it whips across your garage. These cables save lives.
Springs fail because metal fatigues. Each opening and closing cycle puts stress on the coils. Salt air near the coast, humidity, and temperature swings in the Bay Area accelerate wear. Lack of lubrication speeds failure too. A snapped spring is not something that happens "when it's old enough." It's a sudden failure that leaves you locked out or locked in.
If you've noticed your door opening slower than usual or felt the opener work harder, one spring may already be weakening. Get an estimate before it breaks completely. Garage Door Menlo Park offers same-day service and free inspections so you know the real cost upfront.

A single torsion spring replacement costs between $150 and $300 in Menlo Park, depending on the spring's quality and your door's weight. Extension springs run slightly cheaper, around $100 to $200 per spring. Labor is the same either way because both require specialized tools and training.
Many homeowners ask whether to replace one or both springs. If one spring has snapped, the other is likely near the end of its life too. Replacing both at once costs more upfront but prevents a second emergency call in weeks. We recommend replacing both when one fails.
Same-day service means we arrive, diagnose the problem, provide a written estimate, and complete the repair in one visit. No return trips. No waiting. You can schedule a free quote by calling (626) 507-6557 or using our online booking at /contact.

Broken springs always need replacement. Repair isn't an option. A cracked or bent spring cannot be welded or taped back together safely. It will fail again under load, potentially damaging your opener or injuring someone.
If your springs are original to your home and your door is over 10 years old, replacement is coming soon. Preventive replacement on both springs costs less than emergency service on a snapped spring at midnight. We can discuss a maintenance plan during your free estimate.
Regular maintenance extends spring life by 2 to 3 years. Lubrication, balance checks, and opener adjustments keep everything working efficiently. Learn more about keeping your garage door in top shape with routine maintenance.
A garage door with a broken spring is a safety hazard. The door may fall unexpectedly. The opener may overheat trying to lift a dead weight. Children or pets could be injured. Property damage increases too. Never try to force a door open or closed when a spring is broken.
If you suspect a snapped spring, stop using the door immediately. Call a professional. We serve Menlo Park and surrounding communities with emergency repair availability. Your safety is not negotiable.
Garage door springs fail without warning, but they don't fail without reason. Metal fatigue is inevitable. The question is whether you'll replace springs proactively or reactively. Proactive replacement saves money and stress.

How do I know if my garage door spring is broken? A loud bang from the garage is the classic sign. After that, your door won't open or feels extremely heavy to lift manually. The door may hang unevenly or tilt to one side.
Can I use my garage door with one broken spring? No. A broken spring means the other spring must support the full weight alone, which it cannot. This overloads your opener and creates a safety hazard. Stop using the door and call for repair.
How long does a spring replacement take? Our technicians typically complete a spring replacement in 30 to 60 minutes. This includes inspection, removal of the old spring, installation of new springs, balance testing, and safety checks.
Do I need to replace both springs at the same time? Not always, but we recommend it. If one spring snaps, the other is usually near failure too. Replacing both prevents a second emergency call within weeks and costs less overall.
What's the difference in cost between torsion and extension spring replacement? Torsion springs typically run $150 to $300 per spring, while extension springs cost $100 to $200. Labor costs are similar. Material quality and door weight affect final pricing.
