Garage Door Springs Snapped in Wellesley? Here's What Happens Next
7 min read
A customer called last Tuesday morning. Her garage door wouldn't budge. When we arrived, one torsion spring had snapped clean in half, and the second was seconds away from failing. She'd heard a loud bang the night before but thought it was just wind. That moment of delay nearly cost her a second catastrophic failure. If you live in Wellesley and hear that sound, stop using your door immediately and call a professional.
Why Garage Door Springs Fail
Springs carry tremendous load. A typical residential door weighs 300 to 500 pounds, and springs balance that entire weight every time you open or close. Most torsion springs last between 7 to 9 years with normal use, but certain conditions accelerate failure.
Temperature swings, especially in Wellesley winters, cause metal to contract and expand repeatedly. Rust builds up from humidity and salt spray. Lack of lubrication increases friction. Poor balance puts uneven stress on one spring while the other sits idle. When one snaps, the other rarely survives long because it's suddenly forced to handle the full load alone.
Extension springs, which run along the sides of your door, fail more visibly. They'll either snap outright or lose tension so gradually you won't notice until your door feels heavier than normal. Both scenarios require professional attention.
The Immediate Danger
Never try to force a door with a snapped spring. Seriously. We've seen injuries that could have been prevented with one phone call.
A broken spring means your opener is working against dead weight. If you force the door up, it could crash down unexpectedly. Your fingers, a pet, or a parked car could be directly in the path. The opener itself can overheat and burn out, adding another $400 to $600 to your repair cost.
If you suspect a snapped spring, treat your garage door like a locked exit. Don't use it. Call Wellesley Garage Doors or another licensed technician right away. Same-day service exists for exactly this reason.

What a Spring Replacement Really Costs
This is where transparency matters. A single torsion spring replacement typically runs $150 to $300 per spring, depending on the spring's size and quality. Most residential doors have two springs, so budget $300 to $600 for both. Labor adds another $100 to $200 if you hire a professional, which you should.
Why not DIY? Springs are under extreme tension. They can cause serious hand or face injuries if mishandled. We've treated customers who ignored this warning. A professional can assess whether your door is properly balanced, replace both springs simultaneously (even if only one snapped), and test everything before you use the door again.
If your door is over 15 years old and both springs are original, consider replacing both at once. The second spring is likely near the end of its life. Replacing them together saves you a service call in six months.

Prevention and Regular Maintenance
You can't stop springs from aging, but you can slow it down. Lubricate your springs and hardware once a year with a silicone-based lubricant. Avoid WD-40 or general oils, which attract dust and grime.
Keep your door balanced. An imbalanced door puts extra strain on springs and openers. If your door feels heavy when you push it up manually (with the opener off), or if it slides open or closed on its own, call for a balance check.
Regular maintenance catches problems early. During a tune-up, a technician inspects spring condition, measures wear, and alerts you before failure happens. This is far cheaper than emergency repair. Read more about what goes into your complete garage door maintenance guide.
When to Replace vs. Repair
If one spring snapped and the other is still intact, you have options. If both springs are original and over 7 years old, replacement is smarter. If one spring snapped and the other has years left, replacing just the broken one is acceptable, though we recommend replacing both for peace of mind and balanced operation.
Your garage door opener also matters. Older openers sometimes can't handle new springs properly. If your opener is over 10 years old, discuss compatibility with your technician before ordering parts.

Frequently Asked Questions
How do I know if my garage door spring is about to snap? Listen for creaking or groaning sounds. Watch for uneven door movement, slower closing, or the door sagging on one side. These are warning signs. A visual inspection may show rust, gaps, or unusual wear. Call a technician immediately if you notice any of these.
Can I use my garage door if one spring is broken? No. A broken spring leaves the full door weight on the opener and cables, creating safety hazards. Using the door risks injury and expensive opener damage. Stop using it and call for repair.
How long does a spring replacement take? Most replacements take 30 minutes to 2 hours, depending on door type and condition. Wellesley Garage Doors offers same-day service in most cases when you call early.
Why are both springs replaced if only one snapped? The surviving spring has been carrying extra load and is likely weakened. Replacing both ensures balanced operation and prevents a second failure within months. It costs less to do both now than to return twice.
What's the difference between torsion and extension springs? Torsion springs sit above the door and twist to lift it. They're stronger and last longer. Extension springs run along the sides and stretch to help lift. They're cheaper but wear faster and are less safe if they break suddenly.
