Garage Door Springs in Canaan, NH: What to Do When One Snaps
2026-09-09 7 min read
In our Experienced Local Team Canaan, we've seen this problem again and again: a homeowner hears a loud *bang* from the garage, tries to open the door, and nothing happens. A snapped garage door spring is one of the most common emergencies we handle. The good news? It's fixable fast. The reality? You need a professional, and you need one today.
Why Springs Fail (And Why It Happens So Fast)
Garage door springs are under enormous tension. A typical residential door weighs 300 to 400 pounds. Two springs (or one really strong one) bear that load every single day, opening and closing 1,000 to 1,500 times per year. Over 7 to 9 years, that constant tension weakens the metal. Eventually, the spring snaps without warning.
Canaan winters accelerate this wear. Cold temperatures make metal brittle. Salt air and temperature swings (we see 40-degree swings in a single day) create stress fractures. Most snapped springs we pull happen between November and March.
You'll know immediately. The door either won't open at all, or it opens partway and stops. Sometimes you'll hear the bang. Sometimes you won't. Either way, the spring is done.
Torsion vs. Extension: Which One Broke?
Most modern homes use torsion springs. They're mounted horizontally above the door, and they twist to lift the load. Extension springs hang on either side of the door and stretch. Both types fail, but torsion springs are quieter when they go and last longer overall.
If your door is over 10 years old and still has extension springs, replacing them with a torsion system is worth considering. Torsion springs typically outlast extension by a few years, and they're safer if the cable snaps (which it sometimes does alongside the spring).
We handle both types. The repair process is nearly identical, but the cost and timeline depend on which you have. Learn more about torsion vs. extension in our detailed spring guide.

What a Spring Replacement Actually Costs
A single snapped spring runs $150 to $300 for the part and labor, depending on the type and your opener's age. If both springs are original to the door, we strongly recommend replacing both at once. Here's why: when one spring fails after 7 to 9 years, the other is close behind. Replacing just one leaves you vulnerable to a second failure in weeks or months. A full pair replacement costs $300 to $500 and buys you another decade of reliability.
Additional costs can include a new cable (if it frayed during the snap), lubrication, and a safety inspection. An accurate estimate takes five minutes on the phone. We'll ask your door's age, whether you've had the springs replaced before, and what the opener sounds like.
When to Call vs. When to Wait
Don't wait. A snapped spring isn't something you troubleshoot or live with. Your door won't function safely, and you risk damage to the opener if you force it. If the door is stuck open, rain and animals get in. If it's stuck closed, you can't access your garage.
We offer same-day service across Canaan and surrounding towns. Most calls come in by 10 a.m., and we're out the same day. For emergencies outside business hours, check our emergency repair guide to understand what to expect and how we handle off-hours calls.
Preventing Future Spring Failure
The best defense is preventive maintenance. Springs that are lubricated, inspected, and kept under proper tension last longer. A garage door tune-up catches wear before it becomes critical, and it costs far less than an emergency repair.
We also recommend having springs inspected if your door is over 5 years old, especially before winter. Small cracks in the coils are visible to a trained eye. Catching them early means scheduling a replacement on your terms, not at midnight in a snowstorm.

Frequently Asked Questions
How long do garage door springs last? Most springs last 7 to 9 years with normal use (roughly 1,000 to 1,500 cycles per year). Canaan's winter weather can shorten this by 1 to 2 years due to temperature stress and corrosion from road salt exposure.
Can I replace a spring myself? No. Springs are under 200+ pounds of tension. A slip or mistake can cause serious injury or death. Always hire a professional. The cost is worth your safety.
Why do both springs need replacing if only one snapped? Springs wear at the same rate. If one fails after 7 to 9 years, the other is equally worn. Replacing only one leaves you vulnerable to a second failure within weeks, costing you another service call.
What's the difference between emergency and regular repair pricing? Same-day service within business hours costs the same as a scheduled appointment. After-hours or weekend calls may include a $50 to $75 trip fee. The part and labor stay the same.
Should I replace my extension springs with torsion? If your springs are original and over 10 years old, torsion is worth the upgrade. They last longer, operate more smoothly, and are safer if the cable fails. The extra cost is recovered over 3 to 5 years.
