Garage door springs do one job, and they do it thousands of times before they fail. When a snapped spring leaves your door stuck, you need to understand what broke and why. The two main types are torsion springs (mounted above the door) and extension springs (running along the sides). Torsion springs are stronger, last longer, and cost more to replace. We'll walk you through what you need to know to make the right repair decision.
Most modern garage doors in North Chelmsford use torsion springs. These heavy-duty coils sit on a shaft above the door opening and twist to lift the weight. A typical torsion spring lasts 7 to 9 years with normal use (roughly 10,000 to 15,000 cycles). They handle the load more evenly, which is why they outlast their cousins.
Extension springs hang vertically on each side of the door. They stretch and contract as the door moves up and down. These springs are cheaper upfront but wear out faster, usually lasting 4 to 7 years. If you own an older home in the region, you might have extension springs. They're less safe when they fail because the broken metal can whip across the garage.
The cost difference is real. A torsion spring replacement typically runs $200 to $400, while extension springs cost $100 to $200 per pair. But the higher price for torsion reflects better performance and longer intervals between service calls.
Springs wear out through use, not age alone. Every time your door opens and closes, the spring does work. After thousands of cycles, the metal fatigues and eventually snaps. Cold weather can accelerate failure too. Massachusetts winters put extra stress on springs because metal contracts in the cold, increasing brittleness.
You'll know a spring has failed when your door won't open, or the opener struggles to lift it. Never try to force the door open or operate it on a broken spring. You risk injury and damage to the opener motor. A snapped spring is a job for a trained technician. At North Chelmsford Garage Doors, we offer same-day service for spring emergencies across North Chelmsford and surrounding areas like Lowell and Billerica.

The final cost of spring replacement depends on several factors. Door weight matters most. Heavier doors need stronger springs and cost more to replace. The type of spring (torsion vs. extension) also influences price. Single springs cost less than paired extensions. Labor time is another piece. If both springs have failed or are near the end of their life, replacing them together is smarter than doing one now and one later.

Spring replacement is not a DIY project. The tension stored in a compressed or extended spring can cause serious injury. A snapped spring under load can strike your face, hands, or eyes. Even experienced homeowners should step back here. The specialized tools required (spring winders, torque gauges) are not standard garage equipment.
Our technicians train specifically on spring systems. We know how to safely release tension, remove the old spring, and install a new one to exact specifications. We also balance the door afterward so it operates smoothly and the opener isn't overworked.

Don't wait for both springs to fail. If one is broken, the other is likely close behind. Replacing them together saves time and money in the long run.
How long do garage door springs last? Torsion springs typically last 7 to 9 years (10,000 to 15,000 cycles). Extension springs last 4 to 7 years. Lifespan depends on use frequency, climate, and maintenance. Regular lubrication extends life.
Can I replace one spring or should I do both? If one spring breaks, the other is under similar stress and likely to fail soon. Replacing both at once is more cost-effective and prevents a second emergency call within months.
