Garage Door Springs in Thompson: Types, Costs & When to Replace
2026-09-04 7 min read
After 15 years climbing ladders and replacing snapped springs in Thompson and across Connecticut, I can tell you most homeowners don't understand what's actually holding their garage door up. It's not the opener. It's the springs. Let me cut through the confusion and give you the straight story about garage door springs in Thompson so you know when to call and what to expect.
Two Types of Springs: Know the Difference
Your garage door uses one of two spring systems, and which one you have matters for both repair costs and safety. See our guide on garage door springs in thompson: why they fail and how to fix it.
Torsion springs sit above your door on a metal rod. They twist to wind and unwind energy as the door moves. Most homes built in the last 20 years have torsion springs. They're reliable, last 7 to 9 years with average use, and they're safer because the spring stays contained on the rod if it breaks.
Extension springs run along the side tracks above your door. They stretch and contract like a rubber band. Older homes in Thompson often have these. They're cheaper upfront but tend to wear faster, especially in New England winters when cold makes metal brittle. Read about garage door cost & pricing in thompson ct: honest breakdown.
The key difference: a snapped torsion spring is usually a contained failure. A snapped extension spring can whip off its cable and become a projectile. This is why I always recommend torsion springs for replacement work.
Why Springs Fail (And It's Not Always Age)
Springs fail for three main reasons. Age is obvious. A spring rated for 10,000 cycles (about 7 to 9 years of typical use) will eventually wear out. But temperature swings in Connecticut accelerate failure. Winter cold makes metal contract and brittle. Spring thaw brings stress cycles. I've replaced springs in January that could've lasted two more seasons in milder climates.
The third culprit is neglect. Springs need lubrication. A dry spring experiences more friction and fails faster. If you haven't had your garage door serviced in three years, your springs are working harder than they should be.
This connects directly to why winter is peak failure season here. [Why Thompson Garage Door Springs Break in Winter] covers the seasonal mechanics in detail if you want the full picture.

Cost and What Drives the Price
A torsion spring replacement typically costs between $200 and $400 per spring. Extension springs run $150 to $300. But the total bill depends on several factors beyond just the spring type.
Labor is the big variable. If one spring is broken, the other is probably close behind. Most shops (including us at Thompson Garage Doors) replace both springs at once. It costs less than coming back six months later. Whether you need one or two springs affects your estimate.
Your door weight and size matter too. A heavy commercial-style residential door needs stronger springs. A standard single-car door is cheaper. And if the cable or pulley system is damaged when the spring fails, you're adding another $100 to $200 to the repair.

DIY is Not Your Friend Here
I need to be direct: do not try to replace garage door springs yourself. I've seen burned hands, broken fingers, and one guy who nearly lost an eye when a spring exploded. Springs are under 200 to 500 pounds of tension. If something slips during removal, you're in the emergency room.
This isn't like changing a car battery. This requires a spring compressor, proper mounting equipment, and knowledge of how to work safely around pre-tensioned metal. [When to call a professional for garage door spring repair] covers this in more detail.
Call a licensed technician. It's $200 to $400. A hospital visit is $5,000 and up.
What Happens When You Call
When you contact us about a snapped spring or suspected spring failure, here's what happens. We ask a few quick questions. Is the door stuck open or closed? Can you hear a loud bang? Does the door move slowly? These details tell us a lot before we even arrive.
We schedule same-day service when possible. Thompson and nearby towns like Enfield see our trucks within hours on most days. We inspect both springs (even if only one broke), check the cables and pulleys, and give you a clear estimate before we start work.
Most jobs take 45 minutes to an hour. You'll have your door working again the same day.

Frequently Asked Questions
How long do garage door springs last? Torsion springs typically last 7 to 9 years with normal use, rated for 10,000 cycles. Extension springs wear faster, often lasting 5 to 7 years. Climate and maintenance affect actual lifespan. Winter cold and lack of lubrication accelerate failure.
Can I replace just one spring? Technically yes, but we don't recommend it. When one spring fails, the other is close behind. Replacing both at once costs less than a second service call six months later and keeps your door balanced.
What's the difference between torsion and extension springs? Torsion springs twist above the door on a rod. Extension springs stretch along side tracks. Torsion is safer if it breaks, lasts longer, and is more reliable in cold climates. Most new installations use torsion.
Why do springs fail in winter? Cold metal becomes brittle and loses elasticity. Freezing temperatures cause metal to contract, increasing stress on springs. Salt and moisture accelerate corrosion. Spring failures peak in January and February across Connecticut.
Is a broken garage door spring an emergency? Yes. A broken spring can't support your door safely. The door may fall suddenly or won't open. Call a technician immediately. Don't try to force the door open or use the opener.
