Here's what most homeowners don't realize about garage door springs in Marlborough: they're under constant, invisible tension that wears down predictably. A typical torsion spring lasts 7 to 9 years, not forever. When one snaps, your entire door becomes a 300 to 500 pound dead weight that won't open or close safely. I've seen cars trapped in garages, homeowners injured trying to force a broken door, and families unable to park before a storm hits.
Springs are the hardest working component on your garage door system. They counterbalance the weight so your opener doesn't have to do all the lifting alone. Without them functioning properly, nothing else matters, not even the safety features we covered in our post on garage door safety features and what auto-reverse photo eyes actually do.
Two main types exist: torsion springs (the coil above your door) and extension springs (the pair on each side). Torsion springs are more common in residential installations and typically more reliable. Extension springs are cheaper upfront but wear faster because they stretch and contract with every cycle.
Springs fail for three reasons. First, metal fatigue. Every time your door opens and closes, the spring experiences stress. After 7 to 9 years of normal use (roughly 10,000 cycles), the metal becomes brittle. Second, corrosion. Marlborough's humid climate and seasonal temperature swings accelerate rust, especially if springs aren't lubricated during regular maintenance. Third, improper installation or an undersized spring for your door's weight.
When a spring snaps, you'll hear a loud bang from your garage. The door won't open, or it will open partway then slam shut. Never try to force it. A snapped spring means your garage door opener is working alone, and that's a safety hazard.
Replacement cost depends on whether you have a single torsion spring or paired extension springs. A single torsion spring replacement runs $150 to $300 in parts. Extension springs cost $80 to $150 per spring. Labor typically adds another $150 to $250 for professional installation.
Why not DIY? Garage door springs are under extreme tension. A mistake during removal or installation can cause serious injury. I've seen fingers crushed and faces cut by springs that released unexpectedly. Same-day service from Marlborough Garage Doors protects you from those risks and gets you back to normal life quickly.

You can't stop springs from aging, but you can extend their life significantly. Proper maintenance reduces wear. Lubricate your springs and tracks every three to six months with a silicone-based lubricant (not WD-40). Check our detailed post on garage door maintenance and why your tune-up matters for a complete walkthrough.
Keep your garage door balanced. If your door sags on one side or opens unevenly, springs are losing tension. This imbalance accelerates failure in the remaining spring. Test your balance by disconnecting the opener and manually lifting the door. It should stay open at any height without slamming.
Monitor the weather. Extreme cold in New England winters puts extra stress on metal. If you notice your door opening slower in winter, springs may be struggling. This is your warning sign to schedule a free quote before a complete failure traps you.
If one torsion spring snaps, replace both at the same time. They're the same age and under the same stress. The second one will fail within months. Replacing both now costs slightly more upfront but prevents emergency calls later.
For extension springs, replace the broken one only unless you see obvious corrosion on the other. Extension springs fail independently more often than torsion springs.

Spring failure always happens at the worst time. It's 6 a.m. before work, or the night before a storm, or when you're already running late. The smartest move is addressing worn springs before they snap. A trained technician can inspect your springs during a routine maintenance visit and tell you exactly how much life remains.

How long do garage door springs last? Torsion springs typically last 7 to 9 years with normal use (roughly 10,000 cycles). Extension springs wear faster and may need replacement every 5 to 7 years. Lifespan depends on usage, climate, and maintenance habits.
Can I open my garage door if the spring is broken? No. A snapped spring means your door is extremely heavy and dangerous. Do not attempt to open it manually or use the opener. Contact a professional immediately to avoid injury or further damage.
What's the difference between torsion and extension springs? Torsion springs are a single coil mounted above the door and are more durable and reliable. Extension springs are paired springs on each side that stretch and contract. Torsion springs last longer but cost more to replace.
Do I need to replace both springs if one breaks? Yes, replace both torsion springs at the same time since they're the same age and under identical stress. For extension springs, you can typically replace just the broken one unless corrosion is visible.
Why do garage door springs break in winter? Cold temperatures make metal brittle and reduce its flexibility. Existing stress from age or wear becomes more pronounced. Combined with humidity causing rust, winter is peak failure season in Marlborough.
