Let's cut through the confusion about garage door springs. Your garage door has one of two types: torsion or extension. Torsion springs sit above the door and twist to lift it. Extension springs hang on either side and stretch. Most modern doors in Brookline use torsion because they're safer and last longer (7 to 9 years, not 10). Knowing which you have saves money on repair estimates and helps you avoid overpaying.
Torsion springs work like a wound-up toy. When you open the door, they unwind and release energy that helps lift the 300 to 400 pounds of weight. They're mounted horizontally above the door on a metal shaft. One snapped spring means the whole system fails because you've lost half the lifting power on most residential doors.
Extension springs do the opposite. They're coiled like a phone cord and hang vertically on each side of the door. When the door goes up, they stretch. When it closes, they contract. They're cheaper upfront but wear out faster and pose a greater safety risk if they snap. A cable can whip across your garage if an extension spring breaks.
Most homeowners in Brookline and surrounding areas benefit from torsion springs. Yes, they cost more to replace (typically $150 to $300 per spring, plus labor). But they're more durable, quieter, and safer. If your door is older and still has extension springs, upgrading to torsion during your next replacement is worth considering.
Springs fail because of friction and metal fatigue. Every open and close cycle stresses the metal a little more. After 7 to 9 years, the material simply gives out. You can't prevent this, but you can slow it down with regular maintenance.
Here's the real talk: lubricating your springs twice a year with silicone spray reduces friction and can add a year or two to their life. It's a $10 fix that pays for itself. Also, make sure your door opens smoothly. If it's grinding or struggling, the springs are working overtime and will fail sooner. Learn what maintenance actually prevents costly repairs to extend the life of your entire system.

A single torsion spring replacement runs $200 to $350 installed, depending on the spring's size and your door's weight rating. Most residential doors have two springs, so budget $400 to $700 for both. Extension springs are cheaper per unit (around $100 to $150 installed) but often need replacing sooner.
Labor is usually $100 to $150 per spring. The actual part costs $50 to $200 depending on the spring's cycle rating. Higher cycle ratings (meaning the spring is built to last longer) cost more upfront but save money over time.
Don't let a contractor sell you springs you don't need. If only one torsion spring has snapped, you can replace just that one. Replacing both at the same time is smart preventive maintenance since the other one is likely close behind, but it's not mandatory. Get a clear breakdown of what garage door repairs actually cost so you can compare quotes fairly.
When you call for an estimate, describe what happened. Did you hear a loud bang? Is the door stuck? Did the cable go slack? These details tell us which spring failed and what else might need attention.
A reputable company near you will give you an estimate before starting work. Understand the difference between a quote and an estimate so you're not caught off guard by surprise charges. Most springs can be replaced same day, especially if you call before noon.
Avoid the cheapest bid. Springs are safety critical. A contractor who underprices the job might use lower-cycle springs that fail sooner, or they might rush and miss other problems like a worn cable or broken drum. You want someone who takes time to inspect the whole system.

If one torsion spring snaps, the other is usually within a year or two of failure. Replacing both together saves you a second service call and emergency repair fee. The labor cost stays roughly the same because we're already there with the door open.
Think of it like replacing tires. One blowout doesn't mean you need four new tires, but if three are worn, it makes sense to do them all at once. Same logic here.
Replacing both springs together typically costs $500 to $800 installed, versus $200 to $400 for just one. Over three years, you avoid another $200 to $400 emergency call. The math usually favors doing both.
Garage door springs fail. It's not a matter of if, but when. The good news is that replacement is straightforward, fast, and affordable if you act quickly. Don't ignore a snapped spring or a door that won't open. The longer you wait, the more you risk damaging the cable, drum, or opener.

How long do garage door springs last? Torsion springs typically last 7 to 9 years with normal use. Extension springs wear out faster, usually 5 to 7 years. Life span depends on how often you open and close the door and whether you maintain lubrication.
Can I replace a garage door spring myself? No. Springs are under extreme tension and can cause serious injury or death if mishandled. Always hire a licensed technician. DIY attempts are the leading cause of garage door accidents.
What's the difference between cycle rating and lifespan? Cycle rating tells you how many open/close cycles a spring is designed to handle. A 10,000-cycle spring lasts longer than a 5,000-cycle spring. Higher ratings cost more but save money long term.
Why is one spring more expensive than the other? Torsion springs are pricier because they're more complex and safer. Extension springs are simpler and cheaper, but they wear faster and pose greater safety risks if they break.
Should I replace the cable at the same time as the springs? Not always. If the cable looks intact and moves freely, it's fine. But if it's frayed, kinked, or showing wear, replace it during spring service. Cables last about as long as springs, so doing both is smart preventive maintenance.
