A stuck or sluggish garage door usually points to one culprit: spring trouble. In 15 years on the trucks, I've seen countless Mountain View homeowners panic when their garage door won't budge. The good news? Understanding your spring type and what goes wrong helps you act fast and avoid costly mistakes.
Your garage door uses one of two spring systems, and they work in completely opposite ways. See our guide on weather stripping & seals in mountain view: what most homeowners miss.
Torsion springs sit above your door, wound tightly around a metal shaft. They twist and unwind as your door moves up and down. Most modern homes in the Bay Area use torsion springs because they're durable, smooth, and last longer. When a torsion spring snaps, your door either won't open or crashes down suddenly. This is dangerous.
Extension springs hang vertically on each side of your door opening. They stretch as the door lowers and contract as it rises. Older homes often have these. Extension springs tend to wear faster and require safety cables to catch them if they break. Read about garage door safety features in mountain view: which ones actually protect your family?.
Here's what matters: both types wear out. Garage door springs last roughly 7 to 9 years with normal use, not 10. If your door is 8 years old and suddenly feels heavy or won't open without strain, springs are likely the issue.
Springs fail from friction, temperature swings, and constant cycling. Mountain View's mild climate helps, but we still see springs snap unexpectedly. Each time your door cycles, the spring winds and unwinds thousands of times over its lifespan.
Never attempt to replace a garage door spring yourself. The tension is immense. A snapped spring under pressure can cause serious injury. I've treated injuries from botched DIY attempts. Professional technicians use specialized tools and safety procedures.

Listen to your garage door. A loud bang or crack means a spring just snapped. Your door will feel extremely heavy or won't open at all.
Worn springs show subtler signs: the door feels slower to open, the opener struggles, or one side hangs lower than the other. A crooked door often means one spring is weakening while the other still works.

Springs fail less often when your door stays balanced and well-maintained. A crooked door puts extra stress on springs. Annual maintenance catches problems before they become emergencies. Lubricating moving parts and checking balance keeps your system running smoothly.

Sometimes homeowners think springs are bad when the real issue is the opener. A weak opener can't lift a heavy door, mimicking spring failure. A pro can test both systems in minutes and tell you exactly what needs fixing. That's why a same-day estimate matters.
Don't assume springs are the answer without professional diagnosis. Call us and let's figure out what's really happening with your door.
Spring problems don't fix themselves, and they get worse fast. A weakening spring can snap without warning, leaving you without garage access or, worse, dropping a heavy door on someone. Mountain View homeowners trust Garage Door Mountain View for quick, safe repairs.

How long do garage door springs last? Most springs last 7 to 9 years with normal residential use (about 3 to 5 cycles per day). Heavier use shortens lifespan. Temperature changes and lack of maintenance accelerate wear.
Can I replace just one spring? Technically yes, but both springs wear at similar rates. Replacing one while the other is near failure means a second service call soon. Most pros recommend replacing both for balanced performance and cost efficiency.
What's the difference between torsion and extension springs? Torsion springs twist around a shaft above the door; extension springs stretch on each side. Torsion lasts longer and is safer if equipped with cables. Extension springs are older style but still used in some installations.
Is a broken garage door spring an emergency? Yes. A snapped spring means your door is stuck and potentially unsafe. Don't attempt to force it open. Call a professional immediately. We offer same-day service for spring emergencies.
Why is my garage door hanging crooked? One spring has weakened while the other still works, creating uneven lift. This strains both springs and the opener. Get it diagnosed and repaired quickly to prevent total failure.
