Here's what most homeowners don't realize about garage door springs: you likely have one of two completely different types, and they fail for entirely different reasons. After 15 years on the trucks, I've seen countless South Windsor residents panic when a spring snaps because they never knew what they were looking at in the first place. The good news? Understanding torsion versus extension springs takes five minutes, and it could save you real money and hassle.
Torsion springs sit horizontally above your garage door opening. They work by twisting (torsion means "twist") to store and release energy as your door moves up and down. Think of them like a twisted rubber band that powers the entire lift system.
Most residential garage doors in South Windsor use torsion springs because they're efficient, durable, and handle heavy doors better than their cousins. A good torsion spring lasts 7 to 9 years under normal use, assuming you're opening and closing that door 3 to 5 times daily. When a torsion spring finally gives out, the door becomes nearly impossible to lift manually. You'll hear a loud bang or crack when it fails, and the door will sit heavy on the floor.
The cost of replacing a torsion spring is moderate, but DIY replacement is genuinely dangerous. These springs are under extreme tension, and if you slip, you could sustain a serious injury. That's why we always recommend calling a professional for torsion spring work.

Rust, lack of lubrication, and simple metal fatigue are the usual culprits. Connecticut's humid summers and salty winters accelerate corrosion on unprotected springs. If you hear squeaking or see visible rust, it's a sign your spring is aging.
Extension springs run vertically along each side of your garage door opening. Instead of twisting, they stretch and compress as the door moves. They're typically found on older or lighter residential doors.
Extension springs come with safety cables running through the center of each spring. This cable is critical. If an extension spring snaps, the cable catches it and prevents a heavy spring from rocketing across your garage. Without that cable, a snapped spring can cause serious injury or property damage. We've seen it happen in neighboring towns like Windsor and Enfield when homeowners neglect this safety feature.
Extension springs also last around 7 to 9 years, but they often show visible wear before failure. You might notice uneven door movement, slower opening, or visible fraying on the spring itself. The cost to replace an extension spring pair is usually lower than torsion work, but the principle remains: hire a trained technician.

A snapped spring is always an emergency, but you can catch problems early. Listen for grinding or squeaking sounds. Watch for rust stains dripping onto your driveway. If the door feels heavier than usual on manual operation, the spring is losing tension.
Never attempt to adjust, repair, or lubricate springs yourself. The stored energy in a compressed or twisted spring can cause serious injury. Our team at South Windsor Garage Doors handles spring replacement safely, and we offer same-day service when you need it.

A broken spring leaves you stuck. Your door won't open, and a temporary patch isn't safe. The longer you delay, the greater the risk of secondary damage. For example, garage door openers can burn out if they're forced to lift a heavy door with dead springs.

Spring failure is frustrating, but it's also preventable with routine maintenance and timely replacement. Keep your springs in mind during your annual home checkup, and you'll avoid the panic and expense of emergency service down the road.
How do I know if I have torsion or extension springs? Torsion springs run horizontally above the door opening. Extension springs run vertically on each side. Torsion springs are thicker and sit on a central shaft. Look up into your garage to spot which type you have.
Can I replace a garage door spring myself? No. Springs are under extreme tension, and improper handling can cause serious injury. Always hire a licensed technician. The cost of professional service is worth the safety guarantee.
How much does a garage door spring replacement cost in South Windsor? Torsion spring replacement typically ranges from 300 to 500 dollars. Extension springs cost 200 to 400 dollars. Exact pricing depends on your door size and spring specifications. Call for a free estimate.
How long do garage door springs last? Most springs last 7 to 9 years with normal use. Frequency matters: opening and closing 5 times daily wears springs faster than opening 2 times daily. Rust and poor maintenance shorten lifespan.
What should I do if a spring breaks? Stop using the door immediately. Don't force it open or closed. Call a technician right away. A broken spring can damage your opener or cause injury if you try to lift the door manually.
