Garage Door Springs in Stonington: Torsion vs. Extension (Which Do You Have?)
2026-07-10 7 min read
Garage door springs come in two types: torsion and extension. Torsion springs wind and unwind above your door. Extension springs stretch and contract on the sides. Most homes in Stonington use torsion springs because they're safer, last longer (7 to 9 years), and distribute force more evenly. If you don't know which type you have, look above the door frame. Knowing this difference could save your life and thousands in repair costs.
Why This Matters More Than You Think
I've responded to calls where homeowners tried to repair extension springs themselves. The results were devastating. A snapped extension spring can whip across the garage with enough force to cause serious injury. Torsion springs are equally dangerous when broken, but they fail differently.
The real issue? Many Stonington residents don't realize their spring type until it fails. By then, you're either facing an emergency or a much higher repair bill. Understanding what you have now lets you plan ahead, budget for replacement, and avoid the panic that comes with a non functioning garage door.
Extension springs are easier to spot because they run parallel to your door tracks on both sides. Torsion springs sit horizontally above the door and look like a thick metal rod wound tight. If you're unsure, take a photo and call us. We can identify your system in seconds and give you an honest estimate.
The Cost Difference: What You Need to Know
Here's where many homeowners get surprised. Torsion spring replacement typically costs between $200 and $400 per spring, depending on length and wire gauge. Extension springs run $100 to $200 each, but you usually need two. Labor adds another $150 to $300 on top of parts.
That's the estimate when everything goes smoothly. But if your door has been limping along with a weak spring, other components wear faster. Your opener works harder. The door tracks bend slightly. Panels develop stress cracks. Suddenly your $300 spring job becomes a $1,200 repair because secondary damage compounds the original problem.

This is why I always recommend learning the warning signs before disaster strikes. A door that opens slower than normal, uneven movement, or visible rust on the spring are all red flags. Catching these early saves money and keeps your family safe.
Why Torsion Springs Are Usually the Better Choice
Torsion springs have a clear advantage in Stonington's coastal environment. Salt air corrodes metal aggressively. Extension springs, with their exposed coils, rust faster and lose tension sooner. Torsion springs are enclosed and more protected, though they still need annual maintenance in our salty climate.
Torsion springs also distribute the load more evenly across the door. Your garage door opener doesn't strain as much. The door itself experiences less stress. Over time, this means fewer panel repairs and a longer lifespan for the entire system. If you have extension springs now and they're aging, switching to torsion during your next replacement makes sense long term.
The trade-off is upfront cost. Torsion installation requires more precision and specialized tools. This is why DIY replacement is never recommended. A poorly installed torsion spring won't just fail. It can snap violently and damage the door frame, the opener, or worse. Our technicians at Stonington Garage Doors have the right equipment and years of experience to get it right the first time.
When to Call for Help Right Now
If you hear a loud bang from your garage, assume a spring has snapped. Don't try to open the door manually. Don't operate the opener. A broken spring means the door's full weight is no longer balanced. The opener can't lift it, and the door can drop suddenly.

Frequently Asked Questions
How do I know if my garage door spring is about to break? Listen for creaking or squeaking when the door moves. Watch for uneven opening or closing. If one side of the door rises faster than the other, the spring on the slower side is weakening. Rust spots on the spring are another warning sign.
Can I replace a garage door spring myself? No. Torsion and extension springs store enormous energy. A slip can cause serious injury or death. Professional technicians have the right tools, safety equipment, and training. This is one job where DIY saves nothing and risks everything.
How often do garage door springs need replacement? Most springs last 7 to 9 years with proper maintenance. If you use your door more than 15 times daily, expect shorter lifespan. Coastal salt air also accelerates corrosion. Annual inspections help catch wear early.
What's the difference between a spring estimate and final cost? An estimate is based on visual inspection. Final cost may change if hidden damage appears during removal, if your door is larger than standard, or if secondary components need repair. We always call before starting work to confirm pricing.
Is it cheaper to replace one spring or both at the same time? If one spring breaks, replace both. They wear together, and the surviving spring is probably near the end of its life too. Replacing both costs slightly more upfront but prevents a second emergency call in a few months. It's the smarter long-term choice.
