Most people don't think about their garage door until it stops working. That moment usually arrives when a spring snaps. Your door won't budge. You're stuck. And suddenly, you realize these metal coils have been holding 300 to 400 pounds of weight over your head for years, working in near silence. When they fail, they fail hard.
Garage door springs in Swampscott fail predictably. They last roughly 7 to 9 years under normal use, and coastal salt air accelerates corrosion. If your door is older than that, a snapped spring isn't a question of if, but when. This guide explains what you're facing, why DIY repairs are dangerous, and what a replacement actually costs.
Two types of springs support your garage door: torsion springs (wound around a rod above the door) and extension springs (running along the sides). Both work under extreme tension. A single torsion spring can hold pressure equivalent to dropping a car on your hand.
Springs wear from friction and fatigue. Every opening and closing stresses the metal. Salt air in our coastal region accelerates rust, weakening the material from inside. Eventually, the metal fatigues and breaks. Sometimes it's dramatic. Other times, you'll hear a loud bang from the garage and the door drops.
Here's the critical part: a snapped spring means your door's weight is no longer balanced. The opener (your garage door motor) cannot lift it safely. Many homeowners try to force the issue. The motor burns out. The cable tears. Or worse, the unbalanced door comes crashing down on a car, bike, or person.
I've responded to calls where a snapped spring led to $2,000 in additional damage because the homeowner kept trying to operate the door. Don't be that call.
Torsion springs are mounted horizontally above the door. They twist to create lifting power. They're more durable, quieter, and last longer than extension springs. They're also more expensive to replace, but they're the safer choice for most homes.
Extension springs run along each side of the door. They stretch to lift the door open. They're cheaper but wear faster and require safety cables to prevent them from whipping around if they snap. If you have extension springs, replacement is slightly less costly, but the principle remains: get professional help.

A single spring replacement in Swampscott typically runs $150 to $300 per spring, including labor. Most residential doors have one or two springs. If you have two torsion springs, expect $300 to $600 total. Extension springs are slightly cheaper, around $100 to $200 each.
Labor dominates the cost because the work is dangerous and requires specialized tools. A technician must safely release the tension, remove the old spring, install the new one, and balance the door. This takes 45 minutes to two hours.
If your cables are also worn (which often happens alongside spring failure), add another $150 to $300. For a full picture of repair expenses, review our repair cost breakdown guide.
Parts alone are cheap. Professional installation is what you're paying for. And it's worth every dollar.
I understand the temptation. YouTube has videos. Springs look like coils. How hard could it be?
Torsion springs are under 100 to 250 pounds of tension. When you release that tension incorrectly, the spring can unwind violently, breaking bones or causing deep lacerations. I've seen fingers severed. I've seen techs hit in the face by a flying rod.
Extension springs snap and whip. The safety cables are the only thing preventing them from becoming projectiles. Improper installation means those cables fail on the next opening, and the spring launches across your garage.
This isn't pride talking. This is experience. Professional technicians spend years learning to handle these tools safely. A single mistake costs you a hand or your life. The repair cost is cheap compared to that risk.

Torsion and extension springs typically last 7 to 9 years with normal use (about 3 to 5 cycles per day). Coastal salt air in Swampscott accelerates rust and corrosion, shortening lifespan. Inspections every 2 to 3 years help catch wear early.
Technically yes, but experts recommend replacing both. Springs wear at similar rates. Replacing one leaves an unbalanced pair, causing uneven stress and premature failure in the remaining spring. The cost difference is minimal compared to another service call.
In Swampscott and surrounding areas, single spring replacement ranges $150 to $300 per spring, including labor and materials. Torsion springs cost more than extension springs. Get a free estimate by calling (781) 343-7411.
If a spring snaps while the door is open, the door stays open but becomes unbalanced. Don't attempt to close it manually or with the opener. Call a professional immediately. Forcing a broken door closed can damage the opener and create safety hazards.
Most warranties cover springs for 1 to 3 years from installation. After that, springs are wear items and typically not covered. Review your documentation or call us to check your specific warranty status.
