If you've ever woken to a garage door that won't open, you've felt the panic. A snapped spring is often the culprit, and it's not just inconvenient. It's dangerous. In my years servicing Boscawen homes, I've seen garage doors collapse mid-close, trapping vehicles and narrowly missing people. This post explains what you need to know about garage door springs before that happens to you.
Your garage door weighs 300 to 500 pounds. Two springs (or sometimes one, depending on your setup) counterbalance that weight. They're under extreme tension. Torsion springs are the most common type in residential doors. They coil around a metal shaft above the door and store energy as the door closes. Extension springs, typically found on older installations, stretch and contract along the sides of the door frame. See our guide on commercial roll-up garage doors in boscawen: heavy-duty solutions for warehouses.
Springs last 7 to 9 years with normal use. They fail sooner if your garage door cycles frequently, if you live in harsh weather like Boscawen winters, or if maintenance is skipped. The first sign? A loud bang or crack, usually around early morning or late evening when the door is being used.
A snapped spring doesn't just stop the door from moving smoothly. It removes the counterbalance entirely. Your opener motor, designed to lift a balanced load, now tries to lift 300 pounds with no support. The door becomes a crushing hazard. I've documented cases where a snapped spring caused the door to slam shut unexpectedly, breaking bones and crushing fingers. Children and pets are at highest risk.

If your spring breaks while the door is partially open, the door may stay stuck in that position indefinitely. Your car is trapped. Your routine is disrupted. But more importantly, you've lost a critical safety system. That's why we recommend learning about garage door safety fundamentals before an emergency forces the lesson.
Every year, I hear homeowners say they watched a YouTube video and think they can replace a spring. I've also treated injuries from those attempts. Torsion springs carry 10,000+ pounds of force. If a wrench slips, a spring unwinds violently. If you misjudge the tension, the door falls. If you install a spring with incorrect specifications, the door becomes unbalanced and the opener fails prematurely.
Professional technicians use specialized tools: spring winding bars, torque wrenches, and safety cables. We measure your door, calculate the correct spring size, and test the balance afterward. A single mistake costs far more than the original job.

Spring replacement cost in Boscawen ranges from $250 to $500 per spring, depending on door size and spring type. If both springs fail simultaneously (common, since they wear at the same rate), budget $500 to $900 total. Labor typically accounts for 60 percent of the bill; the part itself is 40 percent. Torsion springs cost slightly more than extension springs, but they last longer and are safer.
Don't shop on price alone. A cheap estimate often means the technician is using undersized or mismatched springs. That leads to premature failure and additional costs. We provide a detailed estimate before starting work. For a transparent quote, schedule a free estimate with Garage Door Boscawen.
First: stop. Do not attempt to open or close the door manually. Do not try to prop it up. Call a professional same-day. If your door is stuck open and weather is a concern, close it manually only if two adults can support the full weight without strain. Otherwise, leave it open and call us.
Second: check your opener. If the spring broke while the door was moving, the opener may have overheated or stalled. Don't restart it repeatedly. You'll burn out the motor, and replacement costs $300 to $600.
Third: look at your maintenance routine. Most broken springs are preventable. Regular lubrication, visual inspections, and tension checks catch worn springs before they snap. Learn what homeowners actually need to do in our garage door maintenance guide.
Spring failure is often sudden, but the warning signs appear weeks before. A door that moves slower than usual. A slight noise during opening. A door that doesn't stay fully closed. These are reasons to call for an inspection, not to wait. An inspection costs $75 to $100 and can prevent a $500+ emergency repair plus the inconvenience of a stuck garage door.
Boscawen's cold winters and temperature swings accelerate spring wear. Metal contracts and expands. Lubrication thickens. Springs weaken faster here than in temperate climates. Professional maintenance every 12 months adds years to spring life.

How do I know if my garage door spring is about to break? Listen for creaking or squeaking during opening and closing. The door may move slower than usual, hesitate partway up, or sag at the bottom edge. If you see a visible gap in the spring coil, it's broken or breaking. Stop using the door and call immediately.
Can I use just one spring if one breaks? No. Using one spring on a two-spring door creates severe imbalance. The door will bind, the opener will strain, and you risk injury. Always replace both springs simultaneously, even if only one broke.
How long does spring replacement take? Most jobs take 1 to 2 hours from arrival to testing. Complex installations or dual-spring systems may take longer. We'll provide a time estimate during your inspection.
Do garage door springs come with a warranty? We warranty springs for 1 to 3 years, depending on type. Workmanship is guaranteed for 1 year. Read your invoice for specifics.
What's the difference between torsion and extension springs? Torsion springs coil above the door and are safer, more durable, and last 7 to 9 years. Extension springs stretch along the sides, are less expensive upfront, and last 5 to 7 years. Most modern doors use torsion.
