A snapped garage door spring won't let your door open or close safely, leaving you stuck in your driveway. The two main types are torsion springs (wound above your door) and extension springs (mounted on the sides). Understanding which one you have, why they fail, and what the replacement cost runs helps you make the right call fast. At Biscoe Garage Doors, we handle spring replacement as a core repair, and we've seen enough failures to know what to watch for.
Your garage door weighs 300 to 500 pounds. Springs counterbalance that weight so your opener doesn't burn out and so the door moves smoothly. Without them, your door is a liability. Torsion springs sit on a metal shaft above the door opening, twisting to store and release energy. Extension springs hang beside the tracks and stretch as the door opens, then contract to help close it. Both types work hard every single day. Most springs last 7 to 9 years with regular use, though that timeline shrinks if you open and close your door 10 or more times daily.
Springs wear out because they're under constant tension. Metal fatigues. Rust eats at them, especially in humid North Carolina summers. A snapped spring means your door won't budge without a helper or a second person lifting. That's when homeowners call us for same-day repair.
Torsion springs are the more common choice in modern garages. They're safer than extension springs because they don't snap and whip across the garage. A torsion spring failure is usually a clean break, not a dangerous recoil. Installation and replacement require precise torque calculations. Get the tension wrong and your door operates poorly or puts strain on your opener.
If your door sits above the opening and you see a metal shaft with springs wound around it, you have torsion springs. Replacing them runs between $200 and $400 per spring, depending on the spring's size and your door's weight. We always recommend replacing both springs at once, even if only one snapped. The second one is likely close behind.
Extension springs run along the sides of your door tracks. When the door opens, they stretch. When it closes, they contract and pull the door up. They're less expensive upfront but carry a safety risk. If one snaps, the other absorbs all the load and fails shortly after. A snapped extension spring can also snap a cable, which gets costly.
Extension spring replacement costs $150 to $250 per spring. However, if you're upgrading from extension to torsion (a smart move), expect to pay more for the hardware and installation labor. Many homeowners in Biscoe choose to upgrade because torsion springs are quieter, safer, and last longer under heavy use.

Spring failure usually comes with warning signs. Listen for a loud bang or crack when the door opens or closes. That's often a spring breaking. You might also notice the door moving unevenly, sagging on one side, or refusing to open without help. A door that closes too fast or jerks upward is another red flag.
Rust is the biggest culprit in our climate. Humidity corrodes the metal, weakening it until it snaps under pressure. Lack of lubrication accelerates wear. We recommend a light coat of garage door lubricant on springs twice a year to extend their life. For a deeper look at what causes failure, check out why garage door springs fail in Biscoe and how to catch it before they do.
Regular maintenance also keeps your opener from working too hard. If your opener is struggling, your springs may be failing. Worn springs force the opener motor to compensate, burning it out faster. That's an extra repair you don't want. Learn more about garage door openers in Biscoe to understand the connection.
A spring replacement estimate depends on the type, the door's weight, and whether you need new cables or hardware. Most homeowners in Biscoe pay $300 to $600 for a complete spring replacement job, including labor. If both springs are failing, budget for $500 to $1000. Emergency calls outside business hours add a service fee.
We always provide a free estimate before starting work. Our technicians inspect the rest of your door system to catch other issues. If your opener is aging or your cables are frayed, we'll flag it so you can plan ahead. Preventive repairs save money in the long run.

Not all springs fit all doors. Weight, door size, and cycle frequency matter. A heavy insulated door needs stronger springs than a lightweight single-panel door. If you run a garage-based business with frequent door cycles, heavier-duty springs are worth the extra cost because they'll outlast cheaper alternatives.
When you call us for spring repair services, our team sizes your door and recommends the best option. We stock both torsion and extension springs for most residential doors, so we can often complete the job the same day you call.
Garage door springs don't last forever, but you can extend their life with regular lubrication and timely repairs. Whether you need torsion or extension spring replacement, acting fast prevents secondary damage to cables, openers, and tracks. A snapped spring is never convenient, but it's fixable.
Don't wait if your door isn't opening smoothly or you've heard a loud crack. Schedule a free quote with Biscoe Garage Doors by calling (910) 519-1679. We'll inspect your springs, advise you on the best replacement option, and get your door working safely again.
How long do garage door springs last? Most springs last 7 to 9 years with normal use (about 3 to 5 cycles per day). Frequent use, humidity, and poor maintenance shorten that timeline. We recommend replacing both springs together for balanced operation.
What's the difference between torsion and extension springs? Torsion springs wind above the door opening and twist to lift it. Extension springs run along the side tracks and stretch to open, then contract to close. Torsion springs are safer and last longer; extension springs are older and less expensive.
Can I replace just one spring? Technically yes, but we don't recommend it. The remaining spring is likely near the end of its life and will fail soon. Replacing both at once saves a second service call and keeps door balance consistent.
How much does spring replacement cost in Biscoe? Single spring replacement runs $200 to $400; both springs cost $400 to $800 depending on type and door weight. Emergency same-day service may include an additional fee. Call us for a free estimate.
Is a snapped spring an emergency? Not a safety emergency, but it's urgent. Your door won't open or close without help. We offer same-day repair service. Call (910) 519-1679 as soon as you notice the problem.
