Garage Door Springs in Cambridge: What Homeowners Need to Know
2026-06-01 8 min read
Here's what most homeowners don't realize about garage door springs: they're doing nearly all the heavy lifting every single time your door opens or closes. Your garage door weighs between 300 and 500 pounds. Without properly functioning springs, that weight would crash down on your car, your belongings, or worse. Springs are not luxury parts. They're the foundation of safe, reliable garage door operation.
Understanding Torsion and Extension Springs
Garage doors use one of two spring types, and knowing the difference matters for your safety and wallet.
Torsion springs sit above your door and wind up to counterbalance the weight as it opens. They're mounted on a horizontal rod and twist to store and release energy. Most residential garage doors in Cambridge rely on torsion springs because they're more durable and precise. Extension springs, by contrast, hang on either side of the door and stretch to provide lift. They're cheaper upfront but wear out faster and pose greater safety risks if they snap.
The spring type you have depends on your door's design and weight. A professional can identify which system you're working with and explain why it matters for your specific door.
How Long Do Springs Actually Last?
Springs last 7 to 9 years under normal use, not 10 or 12 like some assume. That timeline assumes your door operates roughly 3 to 5 times per day. If you're opening and closing your door more frequently, springs wear sooner. Climate also plays a role. Cold New England winters, like those we see throughout the greater Boston area, can make metal brittle and shorten spring life.
The best way to extend spring life is simple: use it gently. Don't slam the door. Keep the track clean and lubricated. Have a professional inspect your springs annually as part of routine maintenance.
What Happens When a Spring Snaps
A snapped spring doesn't announce itself kindly. You'll hear a loud bang or crack. Your door may drop suddenly or refuse to open. In some cases, the door still moves but feels heavier than usual. Never try to force a garage door with a broken spring. You risk damaging the opener, the door itself, or worse, injuring yourself.
If you're dealing with a snapped spring right now, you need professional help. This isn't a DIY repair. Springs are under extreme tension, and mishandling them can cause serious injury.

Spring Replacement Cost and What Affects It
Spring replacement cost varies based on the type, quantity, and whether you need one or both springs replaced. Torsion springs typically run $150 to $300 per spring, plus labor. Extension springs are usually cheaper at $100 to $150 each. Labor adds another $150 to $300 depending on complexity. A complete job for both springs might land between $400 and $800 total.
Several factors push costs higher. If your springs are rusted or corroded, removal takes longer. If your door hasn't been serviced in years, the hardware may need attention too. Getting an estimate before work begins is always the right move. Schedule a free quote and we'll give you a transparent breakdown of what needs doing and why.

Preventive Care Keeps Springs Healthy
You can't prevent springs from aging, but you can slow the process and catch problems early.
Inspect your springs visually every few months. Look for rust, gaps, or signs of wear. Listen to your door as it opens. Unusual grinding or squeaking often signals spring stress. Lubricate the springs and hinges with a silicone-based lubricant twice a year. Never oil them; oil attracts dirt and accelerates corrosion.
If you notice your door opening slower than usual, pulling to one side, or feeling heavier, have it checked right away. These are early warning signs that springs are losing strength. Catching problems early saves money and keeps your family safe. For more on year-round door care, our garage door spring replacement guide walks through the full process.
When to Call a Professional
DIY spring repair is never the answer. Springs operate under hundreds of pounds of tension. A slip, misalignment, or wrong tool choice can result in serious injury or property damage. Professional technicians have the right equipment, experience, and insurance to handle the job safely.

Frequently Asked Questions
How do I know if my garage door spring is broken? A loud bang or crack when operating, a door that won't open or feels much heavier, or a visible gap in the spring are clear signs. If you suspect a break, stop using the door and call for professional help immediately.
Can I replace one spring if only one is broken? It's wise to replace both springs at the same time, even if only one snapped. Springs age together, and replacing just one puts uneven stress on the door and opener. Our team will recommend what's best for your door.
How often should garage door springs be serviced? Annual professional inspections catch wear early and extend spring life. Between visits, lubricate springs twice yearly and keep the track clean.
Is spring replacement an emergency repair? Yes, a broken or damaged spring makes your door unsafe. Many homes near Cambridge rely on our emergency repair service to handle spring failures quickly and safely.
What's the difference between a torsion and extension spring? Torsion springs wind above the door and are stronger, more durable, and safer. Extension springs hang beside the door, are cheaper but wear faster, and pose safety risks if they snap. Your door type determines which you have.
