A customer called last Tuesday asking why their garage door opener kept struggling. When I arrived, I found a broken extension spring hiding above the side track. Turns out they'd never learned the difference between torsion and extension springs. That's more common than you'd think. Understanding which type your door uses matters because the repair cost, replacement timeline, and safety concerns differ significantly.
Garage door springs are the hardworking parts that do the heavy lifting. Your door weighs 300 to 500 pounds. Springs balance that weight, making it easy for your opener to raise and lower the door smoothly. Without springs, your opener would burn out in weeks. Springs last roughly 7 to 9 years with normal use. When one snaps, the whole system feels the strain.
There are two main types: torsion springs and extension springs. Your garage door uses one or the other, not both. Knowing which one you have helps you understand repair costs and when to call a pro.
Torsion springs mount horizontally above your garage door opening, on a metal shaft. They work by twisting (torque) to create lifting force. When you open the door, the spring winds tighter. When you close it, the spring unwinds, releasing energy.
Torsion springs are built tough. They handle more cycles and last longer than extension springs. Most residential garage doors in Ashland use torsion springs because homeowners open and close their doors 3 to 5 times per day without issues. Torsion springs are also safer because they're less likely to snap unexpectedly.
If a torsion spring breaks, the door becomes very heavy and potentially dangerous. You'll need professional help right away. Replacement cost typically ranges from $200 to $400 for parts and labor, depending on spring size and your location. Same-day service is often possible if you call early in the morning.
Extension springs run along both sides of the door, above the horizontal tracks. They stretch and contract to provide lift. When the door goes up, the springs extend. When it closes, they compress back to their resting state.
Extension springs wear out faster than torsion springs because they work harder. They're also more prone to snapping without warning. If an extension spring breaks, you'll notice the door tilting to one side. This imbalance can damage your opener and door panels over time.
The good news? Extension springs cost less upfront. Replacement runs $150 to $300 per spring, plus labor. If both springs have worn evenly, replacing just one now means replacing the other soon after. Most pros recommend replacing both at the same time to avoid repeat service calls.

Step outside and look above your garage door. Do you see a long horizontal metal shaft running across the top? That's a torsion spring setup. Do you see springs running along the tracks on both sides? Those are extension springs.
Never attempt to adjust or replace springs yourself. These components are under extreme tension. A snapped spring or loose cable can cause serious injury. Our team at Garage Door Ashland handles all spring work safely and efficiently.

Regular maintenance extends spring life. Lubrication, balance checks, and visual inspections catch problems early. If you keep up with routine garage door maintenance in Ashland, you'll spot wear before a complete failure.
Winter in Ashland is hard on springs. Cold temperatures make metal brittle, and salt air accelerates corrosion. Springs that might last 9 years in a dry climate may need replacement at year 7 here. If your door is over 6 years old and you haven't replaced springs yet, schedule an inspection soon.
A snapped spring doesn't always mean emergency repair costs. Catching wear signs early and replacing proactively saves money and headaches. Learn more about snapped spring repair and same-day options in Ashland if you're dealing with an active break.

How do I know if my garage door spring is about to break? Listen for creaking or squeaking sounds. Watch for uneven door movement, visible gaps in the spring coils, or oil leaks on the shaft. These warning signs give you time to schedule replacement before a complete failure occurs.
Can I replace just one spring if both are the same age? Technically yes, but both springs wear at similar rates. If one snaps, the other is usually close behind. Replacing both at once saves money on service calls and keeps your door balanced properly.
How much does a garage door spring cost in Ashland? Torsion springs run $200 to $400 installed. Extension springs cost $150 to $300 per spring. Costs vary by door size, spring quality, and whether you need same-day service.
Are torsion springs always better than extension springs? Torsion springs last longer and are safer, but extension springs cost less upfront. The best choice depends on your budget, door age, and how often you use your garage.
What happens if I ignore a snapped spring? Your opener works harder and wears out faster. The door becomes unbalanced and may jam. Cables can fray. Repair costs compound quickly. Address spring issues within days, not weeks.
