Garage Door Springs in Windsor: Torsion vs. Extension and When to Replace
2026-08-30 7 min read
Garage door springs carry the weight of your door. When one snaps, you're stuck. The two main types are torsion and extension springs, and knowing which yours uses matters for cost, safety, and repair timeline. Windsor Garage Doors replaces both types on the same day, and this guide cuts through the confusion so you understand what's happening beneath your garage ceiling.
Understanding Torsion vs. Extension Springs
Torsion springs wind around a metal rod above your garage door opening. They twist to lift and lower the door, using rotational force to handle the weight. Most modern homes built after 1990 use torsion springs because they're safer, quieter, and last longer (typically 7 to 9 years with normal use).
Extension springs run horizontally along the sides of your door opening. They stretch and contract like a rubber band to assist the opener. Older homes often have these. They're cheaper upfront but wear faster and pose higher safety risks if they snap because the cable can whip across your garage.
Both types operate under extreme tension. A torsion spring can store 10,000+ pounds of force. Never attempt DIY replacement. A snapped spring is not a weekend project.
Why Springs Fail and What Triggers Replacement
Springs don't last forever. Cycles kill them. Every time your door opens and closes, your springs lose a tiny bit of life. After 7 to 9 years of regular use (roughly 3 to 5 times daily), they're ready to retire.
Cold weather accelerates wear. Windsor winters make metal brittle. If your door suddenly feels heavier or moves unevenly, a spring is likely failing. Listen for a loud bang or crack from the garage. That's often a spring breaking under load.
Rust and lack of lubrication shorten lifespan too. Garage humidity and salt air corrode unprotected springs. You can extend life by having springs lubricated during your annual tune-up, which we cover in our garage door maintenance guide for Windsor homeowners.

Spring Replacement Cost and Estimate
Torsion spring replacement typically costs $200 to $400 per spring, depending on door weight and spring quality. Extension springs run $150 to $250 each. Labor is usually $150 to $300, so a full replacement (many doors have two springs) lands between $500 and $1,000.
Why the range? Door weight matters. A heavy insulated door needs stronger springs than a lightweight single-layer door. Quality matters too. A premium spring rated for 15,000 cycles costs more than a basic 10,000-cycle spring, but lasts longer and fails less often.

Why DIY Spring Replacement Is Dangerous
Springs under tension can cause serious injury or death. Even a small slip while working on a torsion spring can result in the rod spinning violently or the spring unwinding with enough force to break bones or cause lacerations.
A professional brings specialized tools, safety equipment, and experience. We know how to safely relieve tension, remove old springs, install new ones, and test everything before you use your door. The cost of professional service is small compared to an emergency room visit.
If your opener won't lift your door even though it's running, or if you hear a loud crack, stop using the door and call us immediately. See our emergency garage door service page for same-day help.
When to Replace Both Springs at Once
If one spring breaks, consider replacing both. Matched springs wear evenly. If you replace only the broken one, the remaining old spring will likely fail within weeks or months because it's carrying uneven load stress.
New springs come in pairs rated for the same cycle life and weight capacity. Replacing both costs more upfront but saves a second service call and keeps your door balanced longer. Most homeowners find this the smarter move.

Frequently Asked Questions
How long do garage door springs last? Torsion springs typically last 7 to 9 years with normal use (3 to 5 cycles daily). Extension springs wear faster, usually failing in 5 to 7 years. Lifespan depends on door weight, climate, and maintenance frequency.
Can I use my garage door if one spring is broken? No. Do not use your door. A broken spring removes support, forcing your opener to lift the full door weight alone. This can damage the opener, cause the door to fall, or injure someone. Call for emergency repair immediately.
What's the difference between torsion and extension springs? Torsion springs twist above the door and are safer, quieter, and last longer. Extension springs stretch on the sides, are cheaper, wear faster, and pose higher safety risks. Most modern homes use torsion.
How much does a garage door spring replacement cost? Torsion spring replacement ranges $200 to $400 per spring plus labor ($150 to $300). Total cost for both springs is typically $500 to $1,000. Extension springs cost less but fail sooner. Get a free estimate for exact pricing.
Should I replace both springs even if only one broke? Yes. Matched springs wear evenly and share load stress. Replacing only one leaves the old spring to fail soon after, requiring a second service call. Replacing both ensures balanced operation and longer lifespan.
