Garage Door Springs in Sammamish: Torsion vs. Extension (and What They Actually Cost)
2026-09-13 8 min read
Your garage door works because of two springs. One snapped, and suddenly your door won't budge. Most homeowners don't realize these springs carry the weight of your entire door, often 300 to 400 pounds. Torsion and extension springs do the same job differently, fail at different rates, and cost different amounts to replace. Understanding which type you have saves money and prevents dangerous DIY attempts.
What Are Garage Door Springs, and Why Do They Matter?
Springs are the hardest working part of your garage door system. Every time you open or close your door, these metal coils absorb and release tension. Over 7 to 9 years of daily use, metal fatigues. A spring breaks. Your door becomes a thousand-pound paperweight.
Two main types handle this load in Sammamish homes: torsion springs and extension springs. Both are dangerous to replace yourself. Both wear out predictably. Neither lasts forever, and both have distinct cost implications for your household budget.
Torsion Springs: The Overhead Heroes
Torsion springs sit horizontally above your garage door opening. They twist (torque) to lift the door. One spring handles most residential doors. Two springs handle heavier doors. A snapped torsion spring means your door won't open at all.
Why homeowners choose torsion: They're more durable, typically lasting 15,000 to 20,000 cycles. They take up less space. They're smoother and quieter. They also cost more upfront to install, usually $200 to $400 per spring, plus labor.
Sammamish homes with newer construction often have torsion springs. They're the modern standard because they last longer and perform better over time.

Extension Springs: The Budget Alternative
Extension springs run horizontally along both sides of your door frame. They stretch and contract to lift and lower the door. Most older homes in the greater Seattle area still use these.
Why homeowners choose extension: Lower upfront cost, around $100 to $200 per spring. They're easier to find. Replacement is simpler for experienced technicians. The tradeoff? They wear out faster, typically after 10,000 cycles, and need safety cables to prevent injury if they snap.
Extension springs fail more visibly. You'll hear a loud SNAP. The door becomes difficult to open manually. Safety cables prevent the spring from whipping across your garage, but you still need professional help immediately.
Cost Breakdown: What You'll Actually Pay in Sammamish
Spring replacement cost depends on three factors: the type, whether one or both springs fail, and labor rates in your area.
Torsion spring replacement: $300 to $600 total (parts and labor). If both springs fail simultaneously (common), budget $500 to $1,000.
Extension spring replacement: $200 to $400 total. Safety cable replacement may add $50 to $100.
Labor typically runs $150 to $250 per hour. A single spring replacement takes 1 to 2 hours. Many companies offer flat rates instead, which protects your budget.

How to Know Which Type You Have
Walk into your garage. Look above the door opening. If you see a thick metal rod running horizontally with a spring coiled around it, you have a torsion spring. If you see two springs running along the sides of the frame, stretching and contracting, you have extension springs.
Don't touch either one. Springs under extreme tension can cause serious injury. Just identify the type and call a professional. When you schedule a free quote, mention which type you have, and technicians will confirm during inspection.
When to Repair vs. Replace (and Why It Matters)
A snapped spring always requires replacement, not repair. Springs can't be welded or glued back together safely. The metal has fatigued internally. A "repaired" spring will snap again, sometimes violently.
If your door is stuck but springs look intact, the problem might be your opener, cables, or pulleys. That's when repair makes sense. Learn the difference in our guide to when to repair versus replace garage door springs.
Why DIY Spring Replacement Is Dangerous
Springs hold 10,000+ pounds of tension. A single slip releases that energy violently. Fingers, hands, and faces have been seriously injured. Hospital visits cost thousands. Professional replacement costs $300 to $600. That's worth every penny.

Frequently Asked Questions
How long do garage door springs last? Torsion springs last 7 to 9 years with typical use (1,000 to 2,000 cycles per year). Extension springs wear out faster, usually 4 to 7 years. Frequency of use, climate, and maintenance affect lifespan.
Can I replace just one spring if both are old? Technically yes, but it's not smart. If one spring is near the end of its life, the other isn't far behind. Replacing both at once costs a bit more upfront but saves a service call in 6 months.
What's the difference between a snapped spring and a stretched spring? A snapped spring breaks completely and stops working instantly. A stretched spring has lost tension gradually and makes your door harder to open. Both need replacement.
Does homeowners insurance cover spring replacement? Usually no. Springs are considered wear-and-tear maintenance. Check your policy, but expect to pay out of pocket for replacement.
How do I know if my spring is about to fail? Listen for creaking or squeaking. Watch for the door moving unevenly. If opening the door manually feels suddenly heavy, a spring may be weakening. Get it inspected before it snaps.
