Garage door springs are the hardworking backbone of your system, counterbalancing the weight of your door so the opener doesn't strain itself to pieces. If you've ever had a garage door that suddenly feels heavy, won't open smoothly, or makes a loud bang, a failing spring is almost always the culprit. Understanding what type of spring you have, how long it should last, and when replacement becomes necessary is key to keeping your door safe and functional.
Your garage door weighs between 300 and 500 pounds. Without springs, your opener motor would burn out in weeks trying to lift that load. Springs store mechanical energy and release it to help counterbalance the door's weight, making the lift effortless.
There are two main types: torsion springs and extension springs. Torsion springs sit horizontally above your door and twist as the door moves. They're more durable, quieter, and safer because they're contained within a shaft. Extension springs run vertically along each side of the door frame and stretch as the door closes. They're typically cheaper but have a shorter lifespan and can snap more violently.
Most modern residential doors in New London use torsion springs because of their superior safety profile and longevity.
A quality torsion spring lasts 7 to 9 years with average use (opening and closing 4 to 8 times daily). Extension springs typically last 5 to 7 years. These numbers assume normal operation and proper maintenance.
Several factors shorten spring life: coastal salt air (a real issue here near Long Island Sound), temperature swings, rust, and lack of lubrication. If you live in New London's climate, your springs may wear faster than national averages. For more on seasonal impacts, see our guide on why New London winters are rough on garage door springs.
Springs have a cycle rating, usually 10,000 to 15,000 cycles for residential doors. Do the math: at 6 cycles per day, that's roughly 5 to 7 years before fatigue sets in.

A snapped spring is unmistakable: your door either won't open at all or falls hard when opening. But springs fail gradually, and you'll notice the warning signs first.
Look for these red flags:
- The door feels heavier than usual when closing manually, The opener struggles or cycles on and off, Visible rust or corrosion on the spring, The door creeps down when fully open (springs losing tension) - Uneven opening or tilting to one side
If you spot rust or hear a creak when the door moves, don't wait. Rust weakens metal and accelerates failure. A spring that looks corroded could snap within weeks.
If you're unsure whether your springs are the problem, troubleshoot before you call a technician to rule out simpler issues like opener misalignment or sensor problems.
Spring replacement cost varies. A single torsion spring runs between $250 and $400 installed, depending on the spring's quality and size. Extension springs are cheaper, typically $150 to $250 per spring. Many doors have two springs, so budget accordingly.
We always recommend replacing both springs at the same time, even if only one has failed. Matched springs ensure balanced, smooth operation. If one spring is worn enough to snap, the other is close behind.

Springs are under extreme tension and can cause serious injury if mishandled. This is not a DIY job. A spring that releases unexpectedly can cause lacerations or broken bones. We've seen too many garage door accidents in Connecticut from homeowners attempting spring work.
Professional technicians have the tools, training, and insurance to do the job safely. We also test the opener's balance and auto-reverse safety features after installation to ensure everything works as designed.

Your garage door springs deserve the same respect you'd give any high-tension system. Whether you're noticing early wear or dealing with a complete failure, the answer is the same: call a trained technician.

How do I know if my spring is about to snap? Watch for visible rust, reduced door smoothness, and creeping (the door slowly falls when fully open). Rust is the biggest warning sign. If you see orange or brown corrosion, have it inspected within days, not weeks.
Can I replace just one spring? Technically yes, but we don't recommend it. If one spring is worn enough to fail, the other is at similar fatigue level. Replacing both ensures balanced operation and prevents a second failure weeks later.
How much does a torsion spring cost near me? In New London, a quality torsion spring installed typically ranges from $250 to $400. Price depends on spring size, door weight, and whether you need one or two replaced. Call (860) 351-1666 for an exact quote.
Do springs need maintenance? Yes. Lubricate torsion springs every 6 months with garage door lubricant (not WD-40). Wipe away salt residue if you're near the coast. Regular lubrication reduces rust and extends lifespan by 1 to 2 years.
How long does spring replacement take? Most jobs finish in 1 to 2 hours. We test the door's balance and safety features before we leave, so budget extra time for safety checks.
