A snapped garage door spring leaves you stranded. Your door won't open, and the spring that counterbalances its 300+ pound weight has failed completely. This isn't a repair you can postpone or DIY. You need professional help from someone who understands the mechanics and can handle the tension safely.
Garage door springs fail because of metal fatigue. Most torsion springs last 7 to 9 years under normal use. After thousands of open-close cycles, the steel weakens. Temperature swings in Belmont's coastal climate also stress the metal. Cold mornings and warm afternoons create expansion and contraction that accumulates over time.
Extension springs (less common than torsion types) snap for similar reasons. They bear the door's weight directly, stretching and contracting with every operation. Once a spring reaches its fatigue limit, failure happens suddenly. No gradual warning. Just a loud crack and a door that won't budge.
Poor maintenance accelerates failure. Springs need lubrication to move smoothly. Rust and friction shorten their lifespan significantly. If you've skipped routine maintenance, your springs are likely overdue for replacement.

An estimate depends on which spring type you have and how many need replacement. A single torsion spring typically costs between $200 and $400 for parts and labor. If both springs are worn, expect $400 to $600 total. Extension springs run slightly less but require the same professional installation.
Don't shop by price alone. A cheap repair that skips proper inspection or uses low-grade springs will fail again within months. We've seen homeowners pay twice because they chose the lowest bid the first time. Quality springs and correct installation matter.
Our team provides a detailed estimate before any work begins. We inspect the entire door assembly, check the opener, and verify the spring size and type. This thorough approach prevents surprises. You'll know exactly what you're paying for and why.

Never try to open a door with a snapped spring. The opener will strain against the weight it can't lift. You risk burning out the motor or damaging the door itself. The tension in a broken spring system is unpredictable. If you attempt to manually lift the door, the spring assembly could shift and injure you.
Call a professional immediately. That's not overcaution. It's the only safe approach. Our technicians understand spring mechanics and have the right tools to work under extreme tension safely.

Regular maintenance catches worn springs before failure. A technician can measure spring tension and predict when replacement is needed. Catching a spring at 80% wear beats waiting for a snap that leaves you stuck at home or at work.
Lubricate your springs annually. Use a garage door specific lubricant, not WD-40 or general purpose oil. Inspect them visually once a year. Look for rust, uneven wear, or slight separation at the ends. These are warning signs.

Your door's safety depends on healthy springs. Don't ignore the signs. When you hear a snap or your door won't open, contact Garage Door Belmont right away.
Can I open my garage door if one spring is snapped? No. The opener cannot lift the full weight without both springs functioning. Forcing it will damage the motor and door. Wait for professional help.
How long does spring replacement take? Most replacements take 1 to 2 hours. We work quickly without compromising safety. Same-day service is usually available in Belmont.
Are both springs under warranty? We warranty our spring installations for one year against defects. Springs have limited manufacturers' warranties. Ask about our coverage when you call for an estimate.
What's the difference between torsion and extension springs? Torsion springs twist to lift the door. Extension springs stretch. Torsion springs are safer and more common in residential doors. Your door type determines which you need.
Should I replace springs preventively or only when they fail? Replacing both springs together prevents a second failure weeks later. If one is failing, the other is near the end of its life. Preventive replacement saves money and frustration overall.
