A snapped garage door spring means your door won't open, you're stuck, and you need help fast. Springs fail without warning, usually after 7 to 9 years of daily use. The good news: this is fixable, and Lyndeborough Garage Doors handles same-day replacements across the region.
Garage door springs carry enormous tension. A torsion spring (the coiled metal rod above your door) holds roughly 200 to 400 pounds of force. When that spring snaps, the door becomes deadweight. Your opener can't lift it, and you're looking at a door that won't budge.
Springs snap for three main reasons. First, age. Most residential springs last 7 to 9 years, calculated on roughly 10,000 cycles (one cycle equals an open and close). Second, rust and corrosion from humidity and salt air in New England accelerates wear. Third, a manufacturing defect or poor installation can shorten lifespan to just 3 or 4 years.
If your door suddenly dropped or you heard a loud bang from the garage, a snapped spring is the likely culprit. Don't try to open it manually. Forcing a broken-spring door risks injury and can damage the opener permanently.
Before a spring snaps completely, you usually get hints. The door moves slower than normal. It feels heavier when you push it by hand. The opener strains, grinding audibly as it tries to lift the door. Small gaps appear in the spring itself before the final break.
If you've noticed any of these symptoms, don't wait. A garage door tune-up catches worn springs before they fail, saving you from emergency repairs and keeping your family safe.

Torsion springs aren't the only type. Extension springs run horizontally along the sides of your door opening, stretching to help lift the door. They fail for the same reasons: age, rust, wear cycles. When an extension spring snaps, the door becomes unbalanced, pulling to one side.
Extension spring failure is just as serious as torsion failure. Your door won't open, and you risk damage to the tracks and rollers as the door hangs unevenly. Some older homes near Lyndeborough still use single springs instead of paired ones, which makes replacement even more urgent because you've lost 100 percent of spring support.
A snapped spring replacement costs between $150 and $400 per spring, depending on whether you need one or both replaced. Some homeowners assume they can save money with DIY repair. Please don't. Spring systems operate under lethal tension. A slip, wrong tool, or misjudged measurement can cause serious injury.
We've seen cases where homeowners tried to replace springs themselves, got hurt, and ended up in the ER. The hospital bill plus a professional repair afterward cost far more than hiring a technician upfront.

The best response to a snapped spring is preventing the next one. Regular maintenance every 6 to 12 months catches wear early. Lubrication reduces friction. Inspection identifies cracks or rust spots before failure. Our maintenance guide explains exactly what homeowners should monitor.
If your door is over 7 years old and you've never replaced the springs, replacement is coming soon anyway. Planning ahead means you pick the timing instead of the spring picking it for you during a winter storm or when you're late for work.

How long does it take to replace a snapped garage door spring? Most snapped spring replacements take 1 to 2 hours from start to finish. We bring springs in stock, so we avoid delays waiting for parts to ship.
Can I open my garage door if the spring is snapped? No. A snapped spring removes all lifting support. Forcing the door risks injury and can damage your opener. Call a professional instead.
Do both springs need to be replaced at the same time? If one spring snaps, the other is near the end of its life cycle. We recommend replacing both to avoid a second failure weeks later and to keep door movement balanced.
What's the difference between torsion and extension springs? Torsion springs coil above the door opening. Extension springs run horizontally along the sides. Both carry huge tension and require professional replacement.
How can I prevent springs from snapping? Regular maintenance, lubrication every 6 months, and annual inspections catch wear early. Most springs last 7 to 9 years with proper care.
