Garage Door Springs in Chestnut Hill: Torsion vs. Extension Explained
2026-07-07 7 min read
Most people don't think about their garage door until something breaks. Then they realize their springs are the real heroes keeping that heavy door moving safely. If you're in Chestnut Hill and your springs need attention, knowing the difference between torsion and extension springs will save you money and confusion when you call for help.
What Are Garage Door Springs and Why They Matter
Your garage door weighs between 300 and 500 pounds. Springs counterbalance that weight so your opener doesn't strain and your door moves smoothly. Without them, your door becomes a dangerous liability. Springs last roughly 7 to 9 years with normal use, and they fail suddenly, not gradually. When one snaps, you'll know it. You'll hear a loud bang from the garage, and your door will feel impossibly heavy.
There are two main types: torsion springs and extension springs. Most residential doors in the Chestnut Hill area use torsion springs because they're safer, more durable, and quieter. Extension springs are cheaper upfront but wear out faster and pose more safety risks if a cable breaks.
Torsion Springs: The Standard Choice
Torsion springs mount horizontally above your door opening. They work by twisting (torque) rather than stretching. When you open your door, the spring winds up and stores energy. As the door closes, that energy releases, controlling the descent.
Why homeowners prefer them: torsion springs last longer, create smoother operation, and keep tension inside the spring assembly so a broken spring won't cause the door to crash down. If you have a torsion spring that snapped, the door stays put until you can get professional help. This matters for safety in a busy household.
The trade-off is cost. Torsion springs run higher than extension springs, but the longevity and safety justify the price. When you're getting a repair estimate, ask whether your springs are torsion or extension. That detail changes the cost significantly.

Extension Springs: Budget-Friendly but Higher Maintenance
Extension springs run along both sides of the door opening and stretch to create lift. They're cheaper to buy and install, which appeals to homeowners watching their budget. However, they wear out faster (typically 4 to 7 years) and present safety concerns. If a cable breaks, the spring can snap forcefully and damage the door or injure someone nearby.
Extension springs also create more noise during operation. You'll hear creaking and popping sounds that torsion springs avoid. If you have an older Chestnut Hill home with extension springs and you're replacing them anyway, upgrading to a torsion system is worth considering for long-term peace of mind.

How to Know Your Springs Need Replacement
A snapped spring is obvious: sudden loud noise and a door that won't move. But springs can fail without snapping. Watch for these signs: your door opens slower than usual, the opener works harder than it should, or the door feels unbalanced. If you notice your door drifting down slowly on its own, the springs are weakening.
Don't attempt to replace garage door springs yourself. This is a situation where DIY isn't worth the risk. Springs are under enormous tension and can cause serious injury or death if mishandled. Professional technicians have the right tools and training. When you're ready for help, schedule a free quote with us and we'll assess both springs even if only one has failed, since they typically wear out together.
If your door is completely stuck and won't open, we have solutions. Check out our troubleshooting guide on what to do when your garage door won't open for immediate steps you can take.
Spring Replacement Cost and What Affects Pricing
Spring replacement typically costs between $200 and $400 per spring, depending on the type and quality you choose. A two-spring system (common in residential homes) runs $400 to $800 total, plus labor. Some companies charge by the job; others charge hourly. We believe in honest pricing with no surprises. Get a detailed breakdown of repair costs so you understand exactly what you're paying for.
The cost difference between torsion and extension isn't massive, but quality matters. Cheap springs fail sooner, meaning you'll be replacing them again in a few years. Investing in better springs now saves money over time.
Why Professional Installation Matters
Installing springs requires special equipment: a spring winder to safely load tension. One mistake during installation can cost you a finger or worse. After installation, springs need to be properly balanced so your opener doesn't wear out prematurely. Our team at Chestnut Hill Garage Doors handles this correctly every time, and we guarantee our work.
Regular maintenance catches spring problems before they become emergencies. If you haven't had your door serviced recently, our garage door maintenance guide explains what a professional tune-up includes and how it extends your spring life.

Frequently Asked Questions
How long do garage door springs typically last? Torsion springs last 7 to 9 years with normal use. Extension springs wear out faster, usually in 4 to 7 years. The lifespan depends on how often you use your door and maintenance habits.
Can I replace one spring if only one snapped? Technically yes, but we recommend replacing both. Springs wear together, so the remaining spring is likely near the end of its life and will fail soon after, costing you another service call.
What's the difference in cost between torsion and extension springs? Torsion springs typically cost $50 to $100 more per spring than extension springs, but they last longer and are safer, making them the better long-term investment.
Is it safe to use my garage door if one spring is broken? No. A broken spring removes the counterbalance, and your door becomes dangerously heavy. The opener can overheat trying to lift it. Call for professional help immediately.
How do I know if my springs need replacement soon? Signs include slower opening speed, the door feeling heavier, creaking or popping sounds, or the door drifting downward on its own. We offer free inspections to assess your springs' condition.
