A snapped garage door spring will cost you $150 to $400 per spring to replace, depending on spring type, quality, and labor. Torsion springs (the heavy-duty coil above your door) run higher than extension springs (the lighter ones on the sides). Don't attempt this yourself.the tension is dangerous, and a pro gets it done right in under an hour.
Garage door springs come in two main flavors: torsion and extension. Torsion springs are mounted horizontally above the door opening and handle most of the lifting work. Extension springs sit on either side of the door and stretch to assist. Torsion springs typically last 7 to 9 years with normal use, while extension springs wear out faster in coastal climates like Sunset Beach.
Torsion spring replacement costs more because they're engineered to precise specifications for your door's weight. A light residential door might need a spring rated for 10,000 to 15,000 cycles, while a heavy or insulated door demands 20,000+ cycle springs. The cycle rating directly affects the price tag and lifespan.
Extension springs are cheaper upfront (usually $150 to $250 each) but often need replacement sooner. Both types are susceptible to rust and corrosion, especially near the ocean. Salt air accelerates wear, which is why our Sunset Beach customers often see spring failure earlier than inland homeowners. If you haven't read about salt air damage yet, that article covers maintenance strategies that can extend spring life considerably.
Several factors push the final bill up or down. The brand and quality of the replacement spring matter. A basic spring costs less but won't last as long. Premium springs from reputable manufacturers carry a higher price but deliver 20,000 to 25,000 cycles of reliable service.
Your door's weight is another big driver. A standard single-car garage door weighs 300 to 400 pounds. An insulated door or a double-car door easily hits 600 to 800 pounds. Heavier doors need stronger springs, which cost more. Labor also varies. Some techs charge a flat rate; others bill hourly. Most spring replacements take 45 minutes to an hour if only one spring is bad. If both springs are worn (which they often are), expect to replace them together.

I've been doing this work for 15 years, and I've seen homeowners hurt trying to save a few dollars on spring replacement. The coils are under extreme tension. A torsion spring can unwind violently if mishandled, causing serious hand and arm injuries. Even if you have mechanical skill, the specialized tools (spring winder, safety cables) aren't worth buying for a one-time job.
A professional inspection also catches problems DIY attempts miss. We check the cable condition, drum wear, and whether your opener's safety systems are functioning. A snapped spring often indicates that the door has been limping along with uneven weight distribution, which damages other components. When you schedule a free quote, we'll give you the full picture, not just a spring cost.
The best way to know your exact cost is to get a professional assessment. Bring a photo of your door (open and closed) and note when you last had service. This helps us identify whether you're dealing with original springs or replacements. Original springs from installation are usually cheaper but likely wore out years ago.
Our team at Sunset Beach Garage Doors can evaluate your door in minutes and provide a same-day estimate. We'll tell you if one or both springs need replacement and whether your cables and hardware are healthy. If you're in the Sunset Beach area or nearby communities, reach out today. Spring failure won't wait, and neither should you.

Investing in a quality spring replacement pays off. A $300 premium spring lasts nearly twice as long as a $150 budget spring. Over 10 years, the premium option often costs less per year. You'll also avoid the inconvenience and emergency service fees that come with unexpected failures.
If your door is aging or you've had multiple repairs, talk with us about our full spring replacement service. Sometimes replacing both springs at once, even if only one is broken, saves money and headaches down the road. The peace of mind is worth it.
Don't put off spring replacement. A broken spring leaves you unable to open your garage safely, and it puts stress on your opener. Call us at (910) 543-8030 or get a same-day estimate online and get back to normal.
How long do garage door springs last? Torsion springs typically last 7 to 9 years with standard use (about 1 to 3 cycles per day). Extension springs wear out faster, often in 5 to 7 years. Coastal salt air accelerates corrosion, cutting lifespan by 1 to 2 years.
Can I replace just one spring if both are old? Technically yes, but not recommended. If one spring breaks, the other is nearly as worn. Replacing both ensures balanced lifting and prevents a second failure weeks later. Most techs charge labor once, making it cost-effective.
What happens if a spring breaks while the door is open? Nothing immediately dangerous if the door is open. The door won't close without the spring tension, but it's stable. Never try to close it manually. Call a professional to replace the spring before using the door again.
Why is spring replacement more expensive than other repairs? Springs carry high tension and require specialized tools and training to replace safely. The risk of injury is real, and liability insurance reflects that. Professional certification and experience justify the cost.
Do I need to replace my opener when springs break? Not usually. A snapped spring doesn't harm the opener. However, a worn opener may have contributed to uneven spring wear. We inspect both systems and let you know if the opener needs servicing too.
