Here's what most homeowners don't realize about garage door springs: they're under extreme tension and will eventually snap without warning. When they do, your garage door becomes a 300-pound dead weight that neither you nor your automatic opener can lift safely. I've seen injuries that could've been prevented with basic knowledge and timely maintenance.
Garage door springs work in one of two main designs: torsion springs mounted above the door, or extension springs running along the sides. Both types operate under constant stress. Every time you open and close your garage door, the springs lose a tiny fraction of their strength. After roughly 7 to 9 years of normal use, most springs reach the end of their lifespan. See our guide on garage door insulation in exeter: why r-value matters more than you think.
The problem is this: you won't know when failure is imminent. A snapped spring happens in an instant. You might hear a loud crack or bang, and then your door either won't open at all or falls hard if it's already up. At that point, DIY repairs become dangerous and expensive.
Most homeowners assume their springs will last longer than they actually do. Neglect on lubrication, rust from moisture, or heavy usage in New England's climate all shorten spring life. If your door gets used more than twice daily, expect springs to wear faster than the typical timeline. Read about garage door maintenance schedule for exeter homeowners: what to do when.
Torsion springs twist tightly and release energy to lift your door. They're mounted horizontally above the door opening and handle the heavy lifting with precision. Extension springs stretch and contract, pulling cables along the side tracks. Both types fail, but for different reasons.
Torsion springs corrode from humidity and temperature swings common in Exeter and surrounding towns. Extension springs snap when the cable breaks or the spring itself develops micro-fractures. Neither type is "safer" than the other when it comes to sudden failure.
The key difference for you: torsion springs usually need professional replacement because of the extreme tension involved. Extension springs are slightly more accessible but still dangerous to handle alone. One wrong move and you risk serious hand, arm, or head injury. This is not a DIY project, no matter how confident you feel.

When a spring breaks, your garage door's weight redistributes instantly onto the cables, pulleys, and opener. If you try to open the door manually, you're fighting a dead load. If you hit the opener button, the motor strains and can burn out, adding another $300 to $500 in repair costs on top of spring replacement.
I've seen homeowners try to prop up a door with a stick or ladder after spring failure. That's how people get trapped or hurt. A falling garage door can crush fingers, break bones, or worse. Even worse, the door may appear stable and then suddenly collapse.
Our guide on garage door safety in Exeter explains the hidden dangers you're living with every time you ignore spring maintenance.
Spring replacement cost in Exeter typically ranges from $250 to $400 per spring, depending on spring type and door weight. Most residential doors have two springs, so you're looking at $500 to $800 total. Labor takes 1 to 2 hours when both springs are replaced at once. That's why we recommend replacing both simultaneously, even if only one has snapped. The second one is almost always close behind.
Scheduling same-day service keeps your door functional fast. Garage Door Exeter handles emergency spring repairs with rapid response. If you're stuck with a non-functional door, get a same-day estimate by calling us today.
Listen for loud bangs or cracks when operating the door. Watch for the door rising unevenly or hesitating midway. If the door falls quickly when closing or won't stay open when propped, springs are weakening. Rust spots on spring coils are also a red flag, particularly in damp garages or after New England winters.
Don't wait for complete failure. Check our detailed guide on signs you need spring replacement to catch problems early.
Regular maintenance matters too. Our lubrication guide explains why skipping this step costs more long-term.
Stop trying to live with a broken or weakening spring. Call (978) 574-7767 and describe what you're hearing or seeing. We'll schedule a free quote and show you exactly what needs replacing and why. Most calls get answered within minutes during business hours.
This is one of those repairs where hesitation leads to bigger problems and higher costs. Broken springs don't heal themselves. They only get worse until your entire garage door system fails.

How long do garage door springs last? Torsion and extension springs typically last 7 to 9 years with normal residential use, rated for about 10,000 cycles. Heavy use or poor maintenance shortens lifespan significantly. Climate and humidity in New England accelerate wear.
Can I replace a garage door spring myself? No. Springs operate under extreme tension, roughly 200 pounds per spring. Improper handling causes serious injury or death. Professional technicians use special tools and training. Always hire a licensed technician for spring work.
What's the difference between a snapped spring and a worn spring? A snapped spring breaks suddenly, leaving your door completely non-functional. A worn spring weakens gradually, causing the door to rise unevenly, hesitate, or fall faster. Both need professional replacement before secondary damage occurs.
Why do springs fail faster in winter? Cold temperatures make metal brittle and less flexible. Salt and moisture exposure from road conditions increase rust. Frequent garage door use during winter weather stresses springs more than summer operation does.
Should I replace both springs even if only one broke? Yes. If one spring has reached failure, the other is nearly there too. Replacing both at once saves labor costs and prevents a second breakdown within weeks of the first repair.
