Garage door springs come in two main types: torsion and extension. Torsion springs sit above your door and twist to lift the weight. Extension springs run along the sides and stretch. Most homes in Cambridge use torsion springs because they're safer and last longer (7 to 9 years, not 10). A snapped spring means your door won't open, and that's when you call us.
I've responded to dozens of spring emergencies where homeowners tried DIY fixes. The springs hold 400 pounds of tension. One slip, one wrong move, and you're looking at a hospital visit. This post cuts through the confusion about garage door springs and shows you what to expect when something goes wrong. See our guide on brand comparison: what every homeowner should know.
New England winters are brutal on garage doors. Temperature swings from freezing nights to mild afternoons cause metal to contract and expand repeatedly. Over time, this stress weakens the spring material. Salt air near Boston speeds up corrosion. Rust eats into the steel, and suddenly the spring snaps without warning.
Most springs fail between years 7 and 9, but harsh conditions can shorten that window. If your door sounds different (creaking, grinding, sudden loud pop), don't ignore it. A snapped spring might not prevent the door from opening if you have a modern opener with a backup system, but the door becomes a safety hazard. It can drop unexpectedly, and the opener works twice as hard trying to compensate. Read about preparing your garage door for spring: essential tips.
Torsion springs are the gold standard. They're mounted horizontally above the door on a metal shaft and use rotational force to lift the 300 to 400 pound door. Because they're balanced, they last longer and create less strain on your opener. You'll find them on most newer homes and better quality installations around Cambridge.
Extension springs are older technology. They attach to the door frame at each side and literally stretch when the door opens. They're cheaper upfront but fail faster and are less safe. If an extension spring snaps, the cable can whip around. That's why we recommend torsion springs for safety.

A single torsion spring replacement runs between $200 and $300 in labor plus the spring itself. If both springs need replacement (they often do, since they wear together), budget $400 to $600 total. Extension springs are slightly cheaper but fail faster, so you'll replace them more often.
Don't let price be your only guide. We've seen homeowners use low-cost springs from big-box retailers that failed within 3 years. Quality matters. A premium spring costs $50 to $100 more but lasts the full 7 to 9 years. Get an estimate before committing. Our team provides free quotes and can often schedule same-day service if you call early enough.
The cost also depends on whether your door has one or two springs. Most residential doors have two torsion springs working in tandem. When one fails, the other is usually stressed and close behind. Replacing both at once costs more upfront but saves you a second service call in months.

Never attempt spring replacement yourself. The tension is real and dangerous. If you hear a loud bang or your door won't open, that's a snapped spring. Stop trying to force the opener. Instead, schedule a free quote and get a same-day estimate from our team.
Warning signs include the door opening partway and stopping, the opener running but the door not moving, or visible rust and fraying on the spring itself. Even if the door still works, a weakened spring puts extra load on your opener motor. This can shorten the opener's lifespan.
We also recommend spring checks during your regular maintenance routine. If you haven't had your garage door serviced recently, read our step-by-step maintenance guide to understand what a professional inspection covers.
Spring failure isn't something you can delay. A broken spring makes your garage door a safety liability. The door can drop suddenly, and the opener will work harder and fail sooner if forced to compensate.

How long do garage door springs last? Torsion springs typically last 7 to 9 years with normal use. Extension springs fail sooner, often within 5 to 7 years. Harsh winters in Cambridge can shorten this timeline. Regular maintenance helps springs reach their full lifespan.
Can I replace a garage door spring myself? No. Springs are under extreme tension and can cause serious injury or death if mishandled. Professional technicians have specialized tools and training. DIY attempts frequently result in hospital visits. Always hire a licensed technician.
Why do both springs fail at the same time? They wear together. When one spring fails, the other has usually been under extra stress and is close to failure. We recommend replacing both springs together to avoid a second emergency call within months.
What's the difference between torsion and extension springs? Torsion springs twist above the door and are safer, lasting longer. Extension springs stretch along the sides and fail faster. Torsion is the modern standard and worth the small price difference for safety and durability.
How much does a garage door spring replacement cost near me? Expect $200 to $300 for labor plus the spring cost. Replacing two torsion springs totals roughly $400 to $600. Get a free estimate from our team to see exact pricing for your specific door and springs.
