If you've ever dealt with a stuck garage door, there's a good chance your springs are the culprit. Two types of springs support your door: torsion springs and extension springs. Torsion springs twist to lift the door, while extension springs stretch and contract. Both fail eventually, and when they do, your door won't budge. Understanding which type you have and how to spot trouble early can save you money and frustration.
Your garage door weighs between 300 and 600 pounds. Springs counterbalance that weight so your opener doesn't burn out in a year. Without them, your door would crash down or your opener would work twice as hard. Springs typically last 7 to 9 years with normal use, though that depends on how often you open and close your door.
Most modern homes in Sullivan use torsion springs. They're mounted above the door on a rod and twist when the door moves. Older homes sometimes have extension springs that run parallel to the tracks on each side. Both do the same job, but they fail differently and require different replacement approaches.
Torsion springs are the safer, more durable choice. They wear evenly and fail predictably. When they snap, the door stays in place because the springs work together. Replacement cost runs higher (typically $200 to $400 per spring), but you get longer life and fewer headaches.
Extension springs are cheaper upfront but wear unevenly. One spring often fails before the other, which means you'll likely replace both at once anyway. They also pose a safety risk if they snap because the cable can whip around. Most insurance companies and safety codes now require cables on extension springs to contain them.

A snapped spring is obvious: your door won't open or it comes down hard. But there are quieter warning signs worth catching first. If your door moves slower than usual, feels heavier, or makes grinding noises, a spring is likely weakening.
Another clue: listen when you open the door manually. Pull the red emergency cord and lift it by hand. If it's suddenly heavy or jerky, don't wait. A weakening spring puts extra strain on your opener and tracks. We've seen homeowners ignore this until the spring snaps and damages the opener as well, turning a $250 repair into a $500 one.

Spring replacement isn't a DIY job. Torsion springs operate under extreme tension (up to 200 pounds per spring) and can cause serious injury. We always recommend professional replacement.
Cost depends on the type and number of springs. Single torsion spring replacement typically runs $200 to $400. Extension springs are $100 to $250 each. If you need both springs replaced (which is common for extension systems), budget $300 to $500 total. Labor adds another $100 to $150. Some companies charge flat rates; we price each job individually so you never pay for work you don't need.

Cold weather accelerates spring failure. Metal contracts in freezing temperatures, and if a spring was already stressed, winter can push it over the edge. Read our piece on why garage door springs break in winter for prevention tips.
Don't try to open the door. A snapped spring can't support the weight, and forcing it can damage tracks and cables. Call for emergency garage door service in Sullivan right away. We respond quickly and can often fix it the same day.
If you need to get your car out, most of us can use the emergency release to open the door manually (though it'll be heavy). Just don't try to close it without working springs. Call us first.
Our full spring replacement guide covers everything from cost breakdown to what happens during installation.
Once you've decided to move forward, we'll remove the old springs, inspect the cables and pulleys, and install new ones matched to your door's weight. The whole job usually takes an hour. We test everything before we leave and give you a one-year parts warranty.
If your opener is showing signs of strain or your door has other issues, now's a smart time to address them. We're honest about what actually needs fixing.

How long do garage door springs last? Torsion and extension springs typically last 7 to 9 years with average use (opening and closing 4 to 8 times daily). Heavy use or weather extremes can shorten that lifespan. Wear and tear vary by climate and maintenance.
Can I replace one spring or do I need both? If you have torsion springs, you can replace one. For extension springs, it's better to replace both at once because they wear together. If one fails, the other is close behind, and you'll pay for labor twice.
What's the difference between torsion and extension springs? Torsion springs twist above the door and are safer, more durable, and longer-lasting. Extension springs run along the tracks and are cheaper but wear faster and pose safety risks if they snap. Most new homes use torsion.
Is spring replacement an emergency? Yes. A snapped spring makes your door immobile. Call right away for same-day service. Don't attempt to open or close the door yourself, as it can cause injury or additional damage.
How much does spring replacement cost in Sullivan? Torsion spring replacement runs $200 to $400 per spring plus labor. Extension springs are $100 to $250 each. We provide a free estimate after inspection so there are no surprises.
