Garage Door Spring Types in Leominster: Torsion vs. Extension Explained

2026-09-27 5 min read

Most homeowners in Leominster never think about their garage door springs until something breaks. Then suddenly, that door won't budge, and you're stuck wondering what went wrong. The truth is, your garage door relies on one of two spring types to lift that heavy panel hundreds of times a year. Understanding the difference between torsion and extension springs will help you recognize a problem fast and know what to expect when you call for help.

What Are Garage Door Springs?

Your garage door weighs between 300 and 500 pounds. The opener motor can't lift that weight alone. Springs do the heavy lifting by storing and releasing energy. Without functioning springs, your door either won't open, won't close properly, or becomes a safety hazard.

Springs wear out over time. Most last 7 to 9 years with regular use. Once a spring snaps, the door becomes unbalanced and dangerous to operate. That's why knowing your spring type matters for safety and cost when repairs are needed.

Torsion Springs: The Standard Choice

Torsion springs wind and unwind above your garage door opening, rotating on a metal shaft. They're mounted horizontally across the top of the doorway, usually centered. When you open the door, the spring unwinds and releases stored energy. When it closes, the spring winds back up.

Torsion springs are the most common type in modern garages. They're durable, reliable, and last longer than extension springs. They also provide smoother, quieter door operation. A single torsion spring handles most residential doors, though some larger doors use two springs working together.

The main advantage? Torsion springs are safer. They're contained within a shaft and less likely to snap violently. If one breaks, the door falls more gradually rather than crashing down. This matters when kids or pets are nearby.

Extension Springs: Older, Still Common

Extension springs run along both sides of your garage door opening, parallel to the horizontal tracks. They stretch and contract as your door moves up and down. When the door opens, the springs extend. When it closes, they contract and pull the door down.

Extension springs are typically found in older homes or budget installations. They're less expensive upfront than torsion springs, but they don't last as long and often cause more noise and jerky motion. Most extension springs fail sooner, which means higher long-term costs for homeowners.

One safety note: extension springs use pulleys and cables that can break or snap suddenly. If a cable fails, the door can drop fast. That's why extension spring systems should have safety cables running through the springs to catch them if they break.

How to Know Which Type You Have

Walk into your garage and look above the door. If you see a horizontal metal shaft with springs wound around it, you have a torsion system. If you see springs running vertically along both sides of the door tracks, those are extension springs.

Not sure? Don't guess. Misidentifying your spring type can lead to ordering the wrong part or attempting a dangerous DIY fix. When in doubt, call a professional. We can identify your system and explain exactly what needs repair.

Why Spring Type Affects Repair Cost

Torsion spring replacement typically costs more than extension spring work, but the difference isn't huge. The real cost factor is whether you're replacing one spring or both. Some technicians recommend replacing both springs at the same time, even if only one has snapped. This prevents the second spring from failing weeks later and leaving you stranded again.

For a detailed breakdown of spring costs and replacement options, read our guide to garage door springs cost and lifespan. It covers pricing, warranties, and what affects the final estimate.

If your door has already snapped a spring, don't operate it. Learn what to do when a spring breaks and why waiting can turn a simple repair into a bigger problem.

When Should You Replace Springs?

Don't wait for a spring to snap. If your door is slow to open, makes grinding or creaking sounds, or feels unbalanced, springs may be wearing out. A professional inspection can catch a failing spring before it breaks completely. Schedule regular tune-ups to catch spring wear early.

Spring replacement is one of those repairs you want done right. A snapped spring puts stress on your opener motor, cables, and tracks. Replacing springs properly prevents a chain reaction of failures that drives up your total repair cost.
