Garage Door Spring Types in Somers: Torsion vs. Extension Explained
2026-08-11 7 min read
Your garage door relies on springs to lift 300 to 400 pounds with minimal effort. Two main types exist: torsion springs and extension springs. Torsion springs sit above the door and twist to create lift. Extension springs run along the sides and stretch to do the work. Knowing which one you have helps you understand repair costs, safety risks, and when to call a professional.
What Are Torsion Springs?
Torsion springs mount horizontally above your garage door opening. They twist or rotate around a shaft to store mechanical energy. When you open the door, this stored energy releases and helps lift the weight. When closed, the spring rewinds, ready for the next cycle.
Most homes built in the last 20 years have torsion springs. They're more durable, safer, and last longer than their counterparts. A quality torsion spring typically lasts 7 to 9 years with normal use. They handle temperature swings better, which matters in Somers where winters dip below freezing and summers climb toward 85 degrees Fahrenheit.
One snapped spring doesn't always mean both are bad. However, if one fails, the other has been working harder and is likely near the end of its life. Many homeowners find it makes sense to replace both at once rather than face a second failure months later.
What Are Extension Springs?
Extension springs sit on both sides of the door, parallel to the horizontal tracks. They stretch and contract to provide the lifting force. When the door opens, they extend. When it closes, they compress. They're less common in newer installations but still found in older homes throughout Connecticut.
Extension springs typically cost less upfront than torsion springs. They also take up less space. However, they wear faster and don't handle harsh seasonal changes as well. A snapped extension spring is often more visible and easier to spot yourself, but replacement should still be left to professionals.
Safety cables run through or alongside extension springs. These cables catch the spring if it breaks, preventing it from flying across your garage. The cables wear out over time and should be inspected regularly.

Why Springs Fail and When You Need Help
Springs don't just wear out from use. Temperature fluctuations, rust, and poor lubrication all shorten their lifespan. Why garage door springs fail and what replacement really costs explains these failure modes in detail and breaks down what you'll actually pay.
If your door opens unevenly, closes slowly, or won't open at all, a snapped spring is likely the culprit. You might hear a loud bang or crack when it fails. Never try to operate the door with a broken spring. The opener will strain, the cable could snap, and the door itself might crash down.
A proper estimate accounts for the spring type, how many need replacement, and whether cables or other components need service too. Schedule a free quote to get an accurate cost for your specific situation.
Torsion vs. Extension: Which Should You Choose?
If you're replacing springs and have a choice, torsion springs offer better performance and safety. They distribute weight more evenly and are less prone to sudden failure. They also integrate better with modern automatic openers and safety sensors.
Extension springs work fine if your door is lighter or your budget is tight. Just understand they'll need attention sooner. Professional installation matters regardless of type. A poorly installed spring can fail early and create safety hazards.
Homeowners in Somers and nearby towns like Enfield should have their springs inspected at least once a year. How often you should schedule garage door maintenance digs into why regular check-ups prevent emergency calls.

Frequently Asked Questions
How long do garage door springs last?
Most torsion springs last 7 to 9 years. Extension springs typically last 5 to 7 years. Lifespan depends on usage frequency, lubrication, and climate conditions. Professional inspection can help predict when replacement is needed.
Can I replace just one spring?
Technically yes, but both springs have been working equally hard. If one fails, the other is likely near the end too. Replacing both at once is more cost effective and prevents a second failure shortly after.
What does a snapped spring cost to replace?
Costs vary based on spring type and whether cables or tracks need repair. Get an estimate for emergency repair costs to understand typical pricing in your area.
Are torsion springs safer than extension springs?
Yes. Torsion springs rarely fail suddenly and have no moving parts that can whip around. Extension springs have safety cables, but torsion is the safer design overall.
Should I replace springs myself?
No. Spring replacement requires specialized tools and knowledge of proper tension and installation. Incorrect installation risks injury and premature failure. Always hire a professional.
