Here's what most homeowners don't realize about garage door springs: they're under constant tension and can snap without any real warning. A broken spring won't just make your garage door hard to open—it can make it impossible to operate safely. In Redwood City, we get calls weekly from people shocked to learn their springs are at the end of their lifespan, and they need immediate attention.
Your garage door weighs between 300 and 500 pounds. Without springs, that weight would be impossible to lift by hand or even with an electric opener. Two main types do this heavy lifting: torsion springs and extension springs.
Torsion springs sit horizontally above your door and twist to lift the weight. Most modern garage doors use these because they're safer and last longer—typically 7 to 9 years with average use. Extension springs run along the sides of the door and stretch to provide lift. They're cheaper upfront but wear out faster and pose higher safety risks if they break suddenly.
Both types are under extreme pressure. A single cycle—opening and closing—puts real strain on them. After thousands of cycles, metal fatigue sets in, and failure becomes inevitable.
If your garage door feels heavier than usual or won't stay open without the opener running, your springs are probably worn. You might hear a loud bang or snap—that's the sound of a spring breaking under tension. Don't ignore it. A snapped spring forces your opener to work twice as hard, which can damage the motor and opener belt next.
For a detailed breakdown of warning signs, check our post on signs your garage door needs professional repair. Spring failure is one of the most common issues we address.
Another red flag: your door moves unevenly or tilts to one side as it opens. This usually means one spring has failed while the other is still working, creating dangerous imbalance.

Spring replacement cost varies. A single torsion spring typically runs $150 to $300, while extension springs might be $100 to $200 each. Labor is usually $150 to $250, depending on the setup and how accessible your springs are.
The real cost of delay? A broken spring that sits unrepaired can damage your opener ($400–$800 replacement), and you lose the convenience of automatic opening entirely. That's why same-day service matters. At Garage Door Redwood City, we keep springs in stock and can often get you fixed the same day you call.
Your homeowner's insurance won't cover spring replacement—it's wear-and-tear maintenance, not damage. But catching it early saves money on secondary damage. Springs last 7 to 9 years with normal use, so if your door is older than that, budget for replacement soon.
I'll be straight with you: replacing garage door springs is not a DIY job. Springs are under so much tension that even a small mistake can cause serious injury. People have lost fingers, hands, and eyes to spring failures during DIY attempts. The risk isn't worth the savings.
Our technicians have the right tools, training, and insurance to do this safely. We'll inspect both springs even if only one is broken—if one has failed, the other is close behind. We'll also check your opener, cables, and rollers while we're there, so you get honest feedback on what else might need attention soon.

Not all springs are the same. Cheap springs fail faster. We use heavy-duty torsion springs rated for 10,000 to 15,000 cycles—that's 10 to 15 years of typical use. They cost a bit more upfront but outlast budget options by years.
When you get an estimate from us, you're getting honest pricing with quality parts. No hidden fees, no upselling. If your springs need replacement, we'll tell you. If they're fine, we'll say so.
Spring failure is one of those problems that gets worse fast. The longer a broken spring sits, the more stress your opener and cables endure. If you live in Redwood City or nearby areas like San Mateo or Palo Alto, call us for a free inspection. We'll assess your springs and give you a clear estimate with no pressure.
Your garage door should work smoothly and safely. Springs are the backbone of that system, and they deserve professional care.

How do I know if my garage door spring is broken? Listen for a loud bang when opening or closing. Your door may feel heavy, move unevenly, or tilt to one side. Some doors won't open at all with a broken spring. Don't force it—call for professional help immediately.
Can I replace one spring or do I need both? If one spring fails, the other is usually close behind. We recommend replacing both at the same time to avoid a second breakdown weeks later and ensure even weight distribution and door balance.
How long does spring replacement take? Most replacements take 1 to 2 hours, depending on your door's design and any additional issues we find. We often complete work the same day you call.
Are garage door springs covered by warranty? Springs typically carry a 3 to 5-year manufacturer's warranty against defects, but normal wear-and-tear isn't covered. Our labor carries a one-year warranty on all repairs.
What's the difference between torsion and extension springs? Torsion springs twist above the door and last longer (7–9 years). Extension springs stretch along the sides and wear out faster (5–7 years). Torsion is safer and more reliable for modern doors.
