Here's what most homeowners don't realize about garage door springs: they're under constant tension, they wear out predictably, and when they fail, your entire door becomes a 300-pound paperweight. The average homeowner in Medfield and across the Boston area waits until something snaps before calling for help. That's expensive, inconvenient, and unnecessary. Understanding your springs now saves you money, time, and frustration later.
Your garage door uses one of two spring systems, and knowing which one you have matters for cost, safety, and repair timelines. See our guide on winter garage door care: cold weather tips.
Torsion springs sit horizontally above your door opening. They wind and unwind to counterbalance the door's weight as it opens and closes. These are the most common type in modern homes, especially newer construction throughout Medfield. They're precise, durable, and safer than older extension models. Torsion springs typically last 7 to 9 years with normal use (roughly 10,000 to 15,000 open-close cycles). When one fails, you'll notice the door feels heavy or won't open at all.
Extension springs run along the sides of the door tracks. They stretch and contract to lift the door. Older homes and budget installations often use these. Extension springs wear faster than torsion springs and pose a greater safety risk if a cable breaks, since the spring can snap violently. If your door is over 15 years old and you haven't replaced springs, extension springs are likely nearing the end of their life. Read about why weather seals matter for your garage door.
Springs break because of wear, but also because of environmental factors unique to the greater Boston region. Winter salt spray, temperature swings, and humidity all accelerate rust and metal fatigue. A snapped spring rarely comes without warning. Listen for creaking sounds, watch for jerky door movement, or notice if the door feels unbalanced when opening manually. These are signs a spring is weakening.
One spring failure often triggers a second failure within months. Springs work in pairs on most doors, and if one dies, the other has been carrying extra load and is close behind. This is why we always recommend replacing both springs at the same time, even if only one has snapped. It costs less upfront than emergency repairs twice in a season.

Spring replacement cost depends on spring type, your door's weight, and whether you're replacing one or both. A torsion spring replacement ranges from $250 to $400 per spring. Extension springs cost slightly less, around $200 to $350 each. If you need both springs replaced, expect $450 to $800 total for parts and labor, not including service calls.
I won't pretend springs are cheap. But I will tell you this: a DIY spring replacement is a bad idea. Springs carry hundreds of pounds of tension. A wrong move sends metal flying at dangerous speeds. Hospital visits cost far more than hiring a professional. Get a free estimate from us, and we'll give you an honest breakdown before we touch anything.

How do I know if my garage door spring is broken? The door feels extremely heavy when opening manually, won't lift with the opener, or you hear a loud bang from above. A snapped torsion spring creates a visible gap above the door. These are clear signs to stop using the door and call for professional help immediately.
Can I replace just one spring if the other is fine? Technically yes, but not recommended. The remaining spring has carried load longer and is near failure. Replacing both at once costs less than emergency repairs later and ensures balanced door operation. We always recommend replacing both.
How long do garage door springs last? Torsion springs last 7 to 9 years under normal use, roughly 10,000 to 15,000 cycles. Extension springs wear faster, typically 5 to 7 years. Climate, humidity, and frequency of use affect lifespan. New England winters are tough on springs.
Is spring replacement dangerous to DIY? Yes. Springs hold extreme tension. Improper handling causes serious injury or death. Professional technicians use specialized tools and training. The cost of professional service is far less than hospital bills or permanent injury.
Why are springs so expensive? Springs are precision-engineered for your door's specific weight and size. Quality springs last longer and operate safely. Cheap springs fail faster and pose safety risks. We use commercial-grade springs that justify their cost through reliability and durability.
