A customer called last Tuesday morning. Her garage door was stuck halfway open, and she'd heard a loud crack the night before. She assumed the door itself was damaged. When our technician arrived, we found a snapped torsion spring. The door hadn't fallen because the safety cables held, but had those cables failed, the entire 400-pound door could have crashed down. She got lucky. Many homeowners don't.
Garage door springs in Loudon fail silently until they don't. This post explains what you're dealing with, why they snap, and what it actually costs to fix them safely.
Your garage door uses one of two spring systems. The torsion spring sits above the door on a metal shaft, tightly wound to store enormous tension. Extension springs hang on each side of the door track and stretch as the door opens. Both types work the same way: they store energy and release it to help lift the 300 to 500-pound door.
Torsion springs last 7 to 9 years under normal use. Extension springs last slightly longer, around 10 to 12 years. That timeline assumes your door operates 4 to 8 times daily. Heavy use in commercial settings shortens it significantly.
Most homes in Loudon have torsion systems because they're safer and more durable. Extension springs can snap and whip across your garage with dangerous force. If you see two springs on either side of the tracks, you have extension springs. One spring above the door means torsion.
Springs don't just break. They fail because metal fatigues over time. Every opening and closing cycle stresses the coil. Rust accelerates failure, especially in New England where salt and humidity are constant problems. Lack of maintenance is the biggest culprit.
A spring under constant friction wears faster than one that's properly lubricated. Dust and debris get into the coil gaps. Temperature swings cause metal to expand and contract. Eventually, a weak spot gives way.
Here's what catches most homeowners off guard: once one spring fails, the other is usually close behind. They experience the same conditions and same number of cycles. Replacing both springs at once prevents a second emergency call weeks later.

I understand the impulse to save money. Spring replacement looks straightforward online. It isn't. A torsion spring under tension stores enough energy to crush bone. If you slip while adjusting tension, the spring can unwind violently and cause serious injury.
Extension springs can snap during removal and become projectiles. Even experienced mechanics use specialized tools and safety equipment. We've treated customers with lacerations and broken fingers from failed DIY attempts.
Your homeowner's insurance likely won't cover injuries from garage door work. You'll face medical bills plus the full cost of professional repair anyway. The math doesn't work.
If your door is stuck and you suspect a snapped spring, don't attempt to manually open it. Call a professional. Our team at Loudon Garage Doors can diagnose the problem and provide a same-day estimate over the phone.
A basic torsion spring replacement in Loudon ranges from $250 to $450 per spring, including labor. Extension springs cost $150 to $300 each. If both springs need replacement, expect $500 to $1,000 total.
Costs rise if your springs are oversized or if the door has custom specifications. Commercial garage doors with heavier springs cost significantly more. A same-day service call adds urgency fees in some cases, though we try to accommodate emergency requests fairly.
Related to repair expenses, you might also want to understand how maintenance prevents larger bills. Our garage door maintenance guide covers the tune-ups that catch problems early.
For detailed pricing on your specific door, get a free estimate by calling (978) 783-4636 or using our online form. We'll ask about your door's age, size, and spring type to give you accurate numbers.
If one spring is snapped, replace both. If both springs are still functional but showing rust or stiffness, replacement is coming within months anyway. Delaying costs more in emergency fees later.
If your door opens slowly or struggles, springs may be weakening. Don't wait for a complete failure. A technician can assess spring tension and predict failure. Check our comprehensive spring replacement guide for more details on timing and planning.
New springs also improve your opener's lifespan. A struggling opener working against weak springs wears out prematurely. Fresh springs reduce strain on the entire system.
If your garage door has been slower to open, makes grinding sounds, or you've heard any cracking, springs are your first suspect. Don't ignore these warning signs. A single failed spring can strand your car and create a security gap.

How do I know if my garage door spring is broken? The door won't open or opens very slowly even when the opener is running. You may hear a loud snap or bang. One side of the door may sit higher than the other. Never force the door open manually.
Can I replace just one spring? Technically yes, but we don't recommend it. Both springs are the same age and experience identical stress. The second will fail within weeks or months. Replacing both prevents a second emergency call and saves money overall.
How long does spring replacement take? Most replacements take 45 minutes to 2 hours depending on spring type and door condition. We often complete same-day service for Loudon customers. Call for availability.
Are garage door springs covered by homeowner's insurance? No. Homeowner's policies exclude mechanical wear and tear. Spring failure is normal wear. You'll pay out of pocket, making maintenance even more important for budget planning.
What's the difference between torsion and extension springs? Torsion springs sit above the door and twist. Extension springs hang on the sides and stretch. Torsion is safer and lasts longer. Most modern homes have torsion springs.
