Garage door springs come in two types: torsion and extension. Torsion springs sit above the door and twist to lift it; extension springs run along the sides and stretch. Both fail eventually, usually after 7 to 9 years of normal use. When a spring snaps, your door won't open or close safely, and you'll need professional repair right away.
Most homes in Lexington have either torsion or extension springs. Understanding which one you have matters because the repair approach and cost differ.
Torsion springs are the heavier-duty option. They're mounted horizontally above your door, wound tightly to store energy. When you open the door, they unwind in a controlled way, counteracting the door's weight. Torsion springs handle the job more smoothly and last longer than extension springs. They're also safer because they're enclosed and less likely to snap with force.
Extension springs run along each side of the door track. They stretch as the door closes and contract as it opens. They're cheaper upfront but wear out faster, typically in 5 to 7 years rather than 7 to 9. When an extension spring snaps, the sudden release of tension can be violent and dangerous.
The best way to identify yours: look above the door opening. If you see a horizontal spring rod with cable drums on each end, you have torsion. If springs run parallel to the tracks on the sides, you have extension springs.
Garage door springs wear out because of cycle fatigue. Every open and close is one cycle. A typical household door cycles 1,500 times per year. Over 7 to 9 years, that's 10,000 to 13,500 cycles. Metal fatigues under that kind of repetition.
Cold weather accelerates wear. Winter in Lexington and the surrounding Boston area means your springs are working harder because lubricant thickens and metal contracts. If your door feels sluggish in January, your springs are already stressed.
Signs of a failing spring include a door that won't open even when the opener runs, uneven door movement, or a loud bang or crack sound (which means a snapped spring). Don't try to force it. A snapped spring creates serious safety risks and can damage your opener.

Spring replacement isn't cheap, but it's necessary. A single torsion spring costs $150 to $300 for parts plus labor. Extension springs run $75 to $150 per spring. Most doors have either one torsion spring or two extension springs.
Labor adds $150 to $300 depending on complexity. If both springs fail at once (common on extension systems), you're looking at $400 to $700 total. Torsion spring replacement on a standard door typically runs $300 to $500 installed.
The price varies based on your door's weight, spring size, and whether you need same-day service. Emergency calls cost more, but they're worth it if your door is stuck and you can't access your garage.

Torsion springs are under extreme tension. If you try to replace one yourself, the spring can unwind violently and cause serious injury. Extension springs are slightly safer but still dangerous. The cables are under high tension too.

How long do garage door springs last? Torsion springs last 7 to 9 years under normal use. Extension springs typically last 5 to 7 years. Both depend on cycle frequency and climate. Cold winters in Massachusetts can shorten lifespan by 1 to 2 years.
Can I replace just one spring if I have two? Extension springs should be replaced in pairs. If one fails, the other is close behind. Replacing both ensures balanced door movement and prevents premature failure of the second spring. Torsion systems usually have one spring, so that's what you replace.
What's the difference between a snapped spring and a worn spring? A snapped spring breaks suddenly, often with a loud noise. The door won't open. A worn spring weakens gradually, making the door feel heavier or causing uneven movement. Both need professional replacement, but a snap is an emergency.
Why does my garage door spring cost more in winter? Winter demand for garage door repairs is higher, and working in cold conditions is more challenging. Parts may take longer to receive. However, spring failure shouldn't wait. Call immediately if your spring fails, regardless of season.
Should I replace my garage door opener when I replace the springs? Not necessarily. If your opener is less than 10 years old and works well, new springs will restore normal function. Older openers may struggle with new springs because the door will move more smoothly. We can assess this during your inspection.
