Garage Door Springs in Redwood City: Torsion vs. Extension & Repair Guide

2026-09-13 7 min read A2Z Garage Doors

If your garage door won't open, moves slower than usual, or makes a loud bang, a broken spring is likely the culprit. Garage door springs in Redwood City fail more often than most homeowners expect, and understanding which type you have saves time and money when repairs are needed.

Two Types of Springs: Know What's Above Your Head

Your garage door relies on one of two spring systems. Most modern homes use a torsion spring, a heavy-duty coil mounted horizontally above the door opening. Older homes in Redwood City and the Bay Area often have extension springs, which run vertically along each side of the door track.

Torsion springs handle the weight more efficiently and last longer (typically 7 to 9 years with regular use). Extension springs are simpler but wear out faster, usually around 5 to 7 years. Both types store enormous energy. A snapped spring doesn't just stop your door from opening; it can drop the entire panel, damage the opener, or create a safety hazard.

Why Springs Break

Springs fail from everyday wear. Every time your door cycles up and down, the spring flexes thousands of times. Temperature swings in Redwood City, from cool mornings to warm afternoons, also stress the metal. Rust from moisture, poor lubrication, and the sheer weight of your door all accelerate failure.

If you notice your door feeling heavier, sagging on one side, or requiring extra force to lift manually, don't ignore it. A stressed spring often precedes a complete break.

Spotting a Snapped Spring vs. Other Problems

A broken spring usually announces itself loudly. You'll hear a sharp crack or pop, and the door won't move at all, even with the opener running. The opener motor may hum but the door stays put.

If your door moves but slowly, or if one side hangs lower than the other, you're likely dealing with a worn spring that hasn't fully snapped yet. Learn more about what to do in these situations by reading our guide on snapped garage door springs in Redwood City and immediate steps to take.

Spring Repair Cost and What Affects Your Estimate

Spring replacement cost depends on the type, how many have failed, and whether the door itself needs adjustment afterward. Torsion springs typically run higher than extension springs because they're more durable and require precise installation. Labor also varies. If you need both springs replaced (recommended for balanced operation), expect to pay more than a single replacement.

Most homeowners in the area spend between $200 and $400 per spring, including labor. Your actual estimate will depend on your specific door and damage. We offer free estimates for spring repairs; schedule a free quote and get pricing details tailored to your setup.

When to DIY vs. Call a Professional

Don't attempt spring replacement yourself. Springs are under extreme tension. A slip can cause serious injury. Even experienced homeowners risk breaking bones or damaging the door further.

Call a professional. Same-day service is available across Redwood City and nearby areas. A technician will assess whether you need one or both springs replaced, check the door's balance, and test the opener's safety features like the photo eye and auto-reverse system. If safety is a concern, read about garage door safety features and how they protect your home.

Preventive Maintenance Extends Spring Life

Springs last longer with regular care. Lubricate your springs and tracks every few months with a silicone-based garage door lubricant (avoid WD-40). Keep the door balanced and the tracks clean. An annual tune-up catches wear early, before springs fail unexpectedly.

Frequently Asked Questions

How long do garage door springs typically last? Torsion springs last 7 to 9 years with regular use. Extension springs wear faster, usually 5 to 7 years. Lifespan depends on how often you use the door and whether you perform basic maintenance like lubrication.

Can I replace just one spring if both are worn? You can, but replacing both is smarter. Springs wear at similar rates. Replacing one leaves the other ready to fail soon after, costing you another service call and more downtime.

What's the difference between a snapped spring and a stretched one? A snapped spring breaks completely and makes a loud noise. A stretched spring is weakening but still intact, causing the door to feel heavy or move slower. Both need replacement, but a stretched spring gives you time to schedule service.

Why do springs cost different amounts near me? Spring cost varies by type (torsion vs. extension), door weight, brand, and local labor rates. Torsion springs are pricier but last longer. Get an estimate before committing; we offer free assessments in Redwood City.

Is a broken spring covered by my garage door warranty? Most warranties don't cover springs because they're wear-and-tear items. Check your documentation. Some extended warranties do cover them. Ask your technician during your service call.
