Most people don't think about their garage door until it stops working. By then, a snapped spring has already turned a $300 repair into a $600 emergency call. I've responded to hundreds of garage door emergencies across Belmont and the Peninsula, and nearly half involved springs that failed because homeowners missed the warning signs. This post teaches you what those signs are and why timing matters.
Your garage door relies on either torsion springs or extension springs to lift a 300 to 400 pound door smoothly. These springs are under extreme tension from day one. They cycle thousands of times over their lifetime. Springs last roughly 7 to 9 years with normal use. After that, metal fatigue sets in. A snapped spring doesn't just leave you stranded. It's a safety hazard. A door without spring support can fall suddenly, crushing cars, pets, or people below.
Torsion springs sit above your door on a metal rod. Extension springs run along the sides. Both types wear at the same rate, even though they work differently. When one fails, the other is usually close behind. This is critical: don't replace just one spring. You'll be back here in weeks.
The door feels heavier than usual. Open and close it manually (with the opener off). Does it take real effort? Healthy springs do 90 percent of the work. You should barely feel resistance.
You hear a loud bang or snap. This is the sound of a spring breaking under load. If you hear it, don't use the door. Call a professional immediately.
The door opens unevenly or tilts to one side. A failing spring on one side can't balance the weight. The door creeps up crooked. This stresses the cables and opener next.
The door closes too fast or falls suddenly. Loss of spring tension means gravity takes over. This is dangerous and needs same-day attention.

Spring replacement costs vary based on spring type and door size. Expect to pay between $250 and $500 per pair, installed. If you're curious about broader pricing, our cost guide breaks down what Belmont homeowners actually spend. Check the full pricing breakdown for garage door work in Belmont.
Never attempt to replace springs yourself. Springs are under 10,000 pounds of pressure. A slip or mistake can cause serious injury or death. Professionals have winding tools, safety cables, and insurance. We can typically arrive for a same-day estimate and complete the work in under two hours.
Extension springs are slightly cheaper and easier to replace. Torsion springs require more precision and specialized equipment. Both demand a licensed technician. If you notice any of the warning signs above, get a free estimate from Garage Door Belmont. We'll assess both springs, check the cables, and give you a clear cost before we start.
Regular maintenance adds years to your spring life. Lubrication, inspection, and minor adjustments every 12 months can catch wear before it becomes a break. Our preventive care guide outlines the exact steps that save money long-term.
If your door is over 7 years old and you haven't had springs serviced, schedule an inspection now. Don't wait for a break. Belmont's humid coastal climate accelerates metal fatigue, especially in garages near the bay. Rust and salt air shorten spring life compared to inland areas.
Your garage door is one of the heaviest moving parts in your home. Treat it seriously. A few hundred dollars in preventive maintenance beats a $700 emergency call and a broken door trapping your car inside.
Springs are wearing out right now in your garage. You don't feel it yet. But the metal is fatiguing with every cycle. If your door is past the 7-year mark or shows any of the signs above, contact us for a same-day service estimate. We'll give you the exact cost and timeline. Call 650-603-5090 or fill out our contact form. Don't let a snapped spring catch you off guard.
How long do garage door springs last? Most springs last 7 to 9 years with normal use, roughly 10,000 to 15,000 cycles. Coastal salt air in Belmont can shorten this. Springs wear faster if the door is used heavily or not maintained.
Can I replace just one broken spring? No. If one spring fails, the other is near the end of its life too. Replace both at the same time. Replacing one leaves the other to fail days or weeks later, costing you twice.
How much does spring replacement cost in Belmont? Expect $250 to $500 per pair installed, depending on spring type and door size. Torsion springs typically cost more than extension springs. Get a free estimate before committing.
What happens if a garage door spring snaps? The door becomes extremely heavy and may fall suddenly. The opener cannot lift it. You'll be unable to use the garage until it's repaired. This is a safety hazard and needs immediate professional attention.
Is spring maintenance worth the cost? Yes. Annual lubrication and inspection cost $75 to $150 but can add 2 to 3 years to spring life. That's hundreds in savings compared to emergency replacement.
