Garage Door Springs in Hillsborough: Torsion vs. Extension and When to Replace
2026-07-17 7 min read A2Z Garage Doors
Garage door springs in Hillsborough fail without warning, and most homeowners don't know which type they have until one snaps. The two main types are torsion springs (mounted above the door, twisting to lift) and extension springs (on the sides, stretching to pull). Replacing a snapped spring costs between $150 and $400 depending on the type, your door's weight, and whether you need same-day service.
Understanding Torsion vs. Extension Springs
Torsion springs sit horizontally above your garage door opening. They store energy by twisting, then unwind to counterbalance the door's weight as it rises. This design is smoother, quieter, and safer because the spring stays contained. See our guide on garage door maintenance in hillsborough: your 15-year technician.
Extension springs hang on either side of the door and stretch to create lifting force. They're older technology, less expensive upfront, but noisier and more prone to sudden failure. If an extension spring snaps, metal coils can fly across your garage at dangerous speeds.
Most modern homes in Hillsborough use torsion springs because they last longer (7 to 9 years with regular maintenance) and distribute force more evenly. Read about commercial garage doors in hillsborough: what you.
Why Springs Fail and When You Need Replacement
Springs break because they're under constant stress. Every time you open and close your door, the spring cycles. After 10,000 to 15,000 cycles, metal fatigue sets in. Moisture from Bay Area fog, temperature swings, and lack of lubrication accelerate breakdown.
A snapped spring is impossible to ignore. Your door becomes heavy, the opener strains, and you'll hear a loud bang when the spring breaks. Never try to operate a garage door with a broken spring. The opener wasn't designed to lift the full weight alone, and you risk serious injury or damage to the motor.
If you notice your door sagging slightly, opening unevenly, or moving slower than usual, one spring may be failing. Schedule a free quote with us to assess your springs before they snap.

Spring Replacement Cost and What Affects Pricing
The cost to replace garage door springs in Hillsborough varies based on several factors. A single torsion spring replacement runs $200 to $350. Extension springs are usually cheaper at $150 to $250 each, but many doors have two, so you're replacing both for safety reasons.
Labor makes up half the cost. Spring replacement requires specialized tools and knowledge. Improper installation can damage your door, opener, or worse, cause injury. Same-day emergency service adds $50 to $100.
If both springs are old, we recommend replacing both at once. Replacing only the broken one means the remaining spring will likely fail within months. The cost difference is small compared to two service calls.

Maintenance Prevents Costly Failures
Springs last longer with regular care. Lubricate your torsion spring twice yearly with a silicone-based lubricant. Avoid WD-40, which attracts dirt and dries out metal. Keep the area around your springs clean and dry.
If you live near the coast in the Hillsborough area, salt air corrodes springs faster. Annual inspections catch wear before catastrophic failure. Learn more about preventive maintenance schedules to protect your investment.
Our technicians can evaluate spring tension and predict failure risk during a routine maintenance visit. Early detection saves you money and headaches.
When to Call a Professional
DIY spring replacement is dangerous. The springs hold hundreds of pounds of tension. A slip means flying metal or crushed fingers. We've seen too many garage-related injuries that could have been prevented by calling a professional.

Frequently Asked Questions
How long do garage door springs last? Torsion springs typically last 7 to 9 years with proper maintenance. Extension springs wear out faster, usually 5 to 7 years. Lifespan depends on climate, usage frequency, and lubrication habits.
Can I use my garage door if one spring is broken? No. Operating the door with a broken spring damages the opener and risks injury. A garage door without spring support can fall suddenly or become jammed.
Is it cheaper to replace just one spring? Not long-term. If one spring has failed, the other is near the end of its life. Replacing both at once prevents a second service call within weeks and saves labor costs.
What's the difference between a snapped spring and a worn spring? A snapped spring breaks suddenly, often with a loud noise. A worn spring gradually loses tension, causing the door to sag or move unevenly. Both require professional replacement.
Do you offer emergency spring replacement near me? Yes. We provide same-day garage door spring replacement across Hillsborough and surrounding areas. Call 510-880-3615 to schedule service.
