Your garage door springs are the hardest working part of your entire system, yet most homeowners never think about them until one snaps and the door won't budge. Understanding which type you have, how they differ, and what causes failure will save you time, money, and frustration when something goes wrong.
Garage doors use one of two spring systems: torsion springs or extension springs. The choice depends on your door's weight, opening mechanism, and available space.
Torsion springs sit horizontally above your garage door opening. They twist and unwind to lift the door's weight. Most modern residential doors in Greenwich use torsion springs because they're safer, last longer, and distribute force more evenly across the door. A typical torsion spring lasts 7 to 9 years with normal use.
Extension springs run vertically along each side of the door frame. They stretch and contract to support the door as it moves. You'll find these on older doors or in setups where overhead space is limited. Extension springs wear out faster than torsion springs, typically lasting 5 to 7 years, and they carry a higher injury risk because they're under constant tension.
The type you have matters when something breaks. A snapped spring on either system leaves your door stuck, but the repair approach and cost differ. Learn why snapped springs happen and what to do immediately.
Springs don't just wear out randomly. Specific conditions accelerate failure, and understanding them helps you prevent future problems.
Constant cycling is the primary cause. Each time your door opens and closes, the springs compress and extend. Over thousands of cycles, the metal fatigues. If you use your garage door three times daily, your springs age faster than someone who opens it once a day.
Temperature swings hit harder in Connecticut than most people realize. Greenwich winters drop below freezing regularly, and that cold makes metal brittle. Winter weather stress on garage door springs is a documented problem in our region, and spring failures spike from December through February.
Poor maintenance accelerates wear. Springs coated in dust and debris corrode faster. Lack of lubrication increases friction, which means springs work harder with each cycle.
Improper balance forces springs to carry uneven loads. If your door isn't balanced correctly, one spring carries more tension than it should, causing premature failure on that side.

If one spring has snapped, the question isn't whether to fix it. It's whether to replace one spring or both.
Most professionals recommend replacing both springs at the same time, even if only one has failed. Here's why: springs age together. If one spring has reached the end of its lifespan, the other is close behind. Replacing one leaves you vulnerable to a second failure within weeks or months. You'll pay for the service call twice instead of once.
The cost difference between replacing one and two springs is smaller than you'd expect. Labor makes up 60 to 70 percent of the total bill, so adding a second spring adds mainly the cost of the spring itself. Read our detailed breakdown of repair costs in Greenwich to understand pricing for your specific situation.
If your springs are under 5 years old and only one has failed due to a freak event, a single replacement might make sense. But for most homeowners, especially those with torsion springs nearing the 7 to 9 year mark, replacing both is the smarter move.
When a spring breaks, your door is unusable. You can't open it manually without risking injury, and the opener won't function properly. Waiting days for service isn't an option for most families.

How much does it cost to replace garage door springs in Greenwich? Torsion spring replacement typically runs $300 to $500 per spring, including labor. Extension springs cost slightly less. Replacing both springs costs $500 to $900 total. See our detailed pricing guide for 2026 estimates.
Can I replace a garage door spring myself? No. Springs are under extreme tension and can cause serious injury or death if mishandled. Always hire a licensed professional. This is one repair where DIY creates real danger.
How long do garage door springs last? Torsion springs last 7 to 9 years with normal use (about 10,000 cycles). Extension springs last 5 to 7 years. Cold winters and frequent cycling shorten lifespan in both cases.
What's the difference between a snapped spring and a worn spring? A snapped spring breaks suddenly and completely stops your door. A worn spring still works but loses tension gradually. You'll notice the opener struggling or the door closing faster on one side.
Do I need to replace both springs at once? Yes, in most cases. If one spring has failed, the other is nearing the end of its life. Replacing both prevents a second failure weeks later.
