In our years serving South Yarmouth, we've seen this problem again and again: a homeowner wakes up to a garage door that won't open, discovers a snapped spring, and panics about the cost. The truth is simpler than you think. A broken torsion or extension spring typically runs between $300 and $600 to replace, and same-day service is almost always possible. The real question isn't the price. It's whether you should try fixing it yourself or call a professional immediately.
Springs last about 7 to 9 years under normal use. They open and close your door roughly 1,500 times per year. That's a lot of cycles, and metal eventually fatigues.
Torsion springs (the heavy-duty coil above your door) handle the weight directly. Extension springs (mounted on each side) assist with lifting. Both types fail for the same reasons: age, rust, and wear. Coastal salt air in South Yarmouth and nearby Cape Cod accelerates rust, which is why we see more spring failures here than inland areas.
A snapped spring is almost never a surprise to a trained eye. Before complete failure, springs show warning signs: a door that opens unevenly, jerks during operation, or moves slower than usual. If you notice these, contact us for an estimate on spring replacement before the spring gives out completely.
Torsion springs are wound tight and store energy through tension. They're mounted horizontally above the door on a steel shaft. Most modern residential doors use one or two torsion springs. They're safer, more durable, and cost slightly more to replace than extension springs.
Extension springs are coiled like slinky toys and hang vertically on each side of the door. They're cheaper upfront but wear faster and can be more dangerous if they snap. A broken extension spring can cause the door to drop suddenly.
We need to be direct here: replacing garage door springs yourself is one of the most dangerous home repairs you can attempt. Springs are under extreme tension, often 200 pounds or more per spring. A slip, miscalculation, or wrong tool placement can cause serious injury.
We've treated customers who tried DIY repairs and ended up with broken fingers, crushed hands, or worse. It's not worth the risk or the small savings. Professional spring replacement takes us about an hour and includes safety checks on your entire door system.

Here's what you'll actually pay for a snapped spring in South Yarmouth. A single torsion spring replacement runs $300 to $450, depending on the spring's weight rating. If both springs are original, replacing both at the same time costs $550 to $600 (we discount the second spring slightly).
Extension springs are cheaper: $200 to $350 per side, but we recommend replacing both sides together to keep the door balanced. Service call fees range from $50 to $85, though many shops waive that if you proceed with repair.
If you're shopping around, watch for quotes that seem too low. We've seen competitors offer $150 spring replacements, then charge extra for labor, inspection, or cable work they "discovered" during the job. Our pricing guide for garage door costs in South Yarmouth breaks down what's fair and what's a red flag.
If your door is 15+ years old and the spring just failed, it might make sense to replace the entire unit rather than patch one more component. A new door with a quality opener runs $1,200 to $2,500 installed, depending on size and insulation. A spring repair is $400 to $600.
Do the math: if your door is ancient and the spring is the third major repair in five years, replacement is smarter. If your door is 5 to 10 years old and this is the first significant failure, repair makes sense.

Winter cold thickens lubricants and makes metal brittle. Spring failures spike in January through March. Summer heat can accelerate wear, though actual failures are rarer. If your spring is showing signs of trouble, address it before winter arrives.
Our coastal garage door maintenance guide covers seasonal prep that extends spring life and prevents mid-winter emergencies.
How do I know if my spring is broken? The door won't open or opens very slowly. You may hear a loud bang or snap when failure occurs. Never force the door open manually if the spring is broken; you risk serious injury. Call us for immediate assistance.
Can I still use my garage door with a broken spring? No. Operating the door stresses the opener motor and can damage other components. The door becomes a safety hazard. Wait for professional repair.
How long does spring replacement take? Most jobs take 45 minutes to an hour. We can often accommodate same-day appointments, especially for urgent snapped spring calls in South Yarmouth and the surrounding area.
Do I need to replace both springs if only one broke? If both springs are original and the same age, yes. They wear together, and replacing one creates an imbalance. New springs with old springs causes uneven door movement and accelerates wear on the remaining spring.
What's the lifespan of a new spring? Quality springs last 7 to 9 years with normal use. Coastal weather and frequent door cycles can shorten that to 5 to 7 years. Regular lubrication and maintenance help maximize longevity.
