There's a reason spring failures are the most common garage door emergency call in Central Massachusetts. It's not bad luck. it's physics, weather, and the age of the housing stock all working against you at once. In Leicester, where the average home was built around 1968 and January temperatures regularly bottom out near 19°F, the conditions for premature spring wear are almost textbook. If your door suddenly feels impossibly heavy or refuses to open at all, there's a good chance a spring has given out. and understanding why helps you prevent the next one.
Garage door springs. both torsion springs (mounted horizontally above the door) and extension springs (running along the tracks on each side). work by storing mechanical energy. Every time your door opens and closes, the spring completes one cycle. Standard springs are rated for around 10,000 cycles. At two uses per day, that's roughly 13 years before the spring is statistically due for failure.
But that 13-year estimate assumes moderate, consistent conditions. In Leicester, conditions are rarely moderate. The temperature swings here are significant. winter lows near 19°F and summer highs pushing 80°F mean the steel coils in your springs are constantly expanding and contracting. Sharp winter temperature shifts cause steel to stiffen and fatigue faster than manufacturers' cycle ratings account for. Add in the humidity that comes off Sargeant Pond and Moose Hill Reservoir in warmer months, and you have conditions that accelerate rust formation on exposed spring coils. another key driver of early failure.
Homeowners in Shrewsbury and Grafton report the same pattern: springs that fail in late January or early February, right when temperatures are at their coldest and the steel is under maximum stress.
Springs rarely fail without giving some warning first. The problem is that the warning signs are easy to dismiss as normal wear. Here's what to watch for:
- The door feels heavier than usual when you lift it manually. A properly balanced door should stay in place when lifted to waist height and released. if it drifts down, the spring tension is off. - Sluggish movement on the opener, especially at the start of the lift cycle, often means the spring is losing tension and the motor is compensating. - Visible gaps or separation in the coil of a torsion spring. a spring under normal tension has coils that are tightly wound and evenly spaced. - Rust or corrosion on the coils. Even surface rust increases friction inside the coil and shortens the remaining service life significantly. - A loud bang from the garage, sometimes mistaken for something falling or a car backfiring. This is the classic sign of a spring that has snapped completely.
If you notice the door feeling off-balance or sluggish, that's the right time to call. not after the spring breaks entirely.
When a torsion spring snaps, the garage door becomes extremely heavy. a standard two-car door can weigh 150,200 pounds or more without spring assistance. Your opener motor was never designed to lift that weight alone, and attempting to run the door in this condition will strip the gears or burn out the motor in a single cycle.
If you hear a loud crack and your door won't open, or opens only a few inches before stopping, stop pressing the button. Disengage the opener and do not attempt to manually lift the door. Contact Garage Door Leicester for same-day service. this is one of those situations where waiting makes the repair more expensive, not less.
Yes, and the type affects both repair cost and longevity. Torsion springs are mounted on a shaft above the door and are the more modern, reliable design. They distribute weight more evenly, last longer, and are safer when they fail. a broken torsion spring generally stays on the shaft rather than flying loose. Most newer homes in Leicester with attached garages will have torsion springs.
Extension springs are the older design, running along the horizontal tracks on each side of the door. They're common in older Cape Cod and ranch-style homes. exactly the housing types that make up a large portion of Leicester's single-family stock. Extension springs should have safety cables running through them; without those cables, a broken spring can become a dangerous projectile. If your system has extension springs without cables, that's something worth addressing during your next service visit. You can learn more about related safety considerations in our post on pinch protection and garage door safety.
This is not a DIY job under any circumstances. Springs are under hundreds of pounds of stored tension, and the release of that energy during a failed DIY repair can cause serious injury. Professional technicians use specialized winding bars and follow precise protocols to safely remove and replace springs.
When one spring breaks on a two-spring system, it's standard practice to replace both at the same time. The surviving spring has the same wear history as the failed one and will likely break within weeks or months if left in place. Replacing both now saves a second service call. and a second opener motor at risk.
A professional will also check cable tension, drum alignment, and overall door balance during a spring replacement. These components all interact, and a new spring installed without verifying the rest of the system is balanced leaves the door at risk of premature wear on the new hardware.
You can't make a spring last forever, but you can get closer to. or even exceed. its rated cycle life with consistent maintenance:
1. Lubricate springs every six months with a silicone-based garage door lubricant. This reduces friction inside the coils and slows rust formation. Apply sparingly and wipe off the excess. Never use WD-40 or grease. 2. Schedule an annual inspection, ideally in early fall before Leicester winters set in. A technician can spot micro-fractures, tension loss, and early corrosion before they become a failure. 3. Test your door's balance a few times a year. Disconnect the opener, lift the door to waist height, and let go. A balanced door stays put. If it drifts, the spring tension needs adjustment. 4. Watch for rust on the coils, especially after a wet spring or humid summer. Surface rust that's caught early can be addressed; a deeply corroded coil needs replacement.

Garage Door Leicester works with homeowners throughout Leicester and the wider Worcester County area. If you're unsure about the current condition of your springs or haven't had an inspection in a few years, our services page covers what a tune-up includes and what to expect.
Q: How do I know if I have a torsion spring or extension springs?
A: Look above the door when it's closed. If you see a single horizontal metal rod with a coiled spring wound around it, that's a torsion system. If you see springs running horizontally along the tracks on each side of the ceiling, those are extension springs. Both systems are common in Leicester homes depending on when the garage was built.
Q: My door opens but feels slow and labored. could that be a spring problem?
A: Yes. A spring that's losing tension forces the opener motor to work harder to lift the door. This is a common early warning sign, particularly in winter when cold reduces spring tension further. Left unaddressed, it puts serious strain on the opener and can shorten its lifespan considerably. Have a technician check the spring tension and door balance before the spring fails completely.
Q: Is it worth upgrading to higher-cycle springs when replacing?
A: For most Leicester homeowners, yes. High-cycle springs rated for 25,000,30,000 cycles cost more upfront but last two to three times longer than standard springs. Given the thermal stress that Central Massachusetts winters put on garage door hardware, the longevity upgrade is usually worth the additional cost.
