Why Are Garage Door Springs Dangerous: Think Before DIY

Published: Jan 7, 2026

A garage door spring might seem like just another metal coil — until it snaps. For many American homeowners and business owners, a noisy or stuck garage door leads to one tempting thought: “I’ll just fix the spring myself.” Before grabbing a wrench, it’s important to understand one key thing: “why are garage door springs dangerous?” — and how much tension you’re really dealing with.

This guide from 24H Garage Doors explains the dangers of garage door springs, how the springs actually work, and why calling in a pro is more than just a safe bet — it’s the best way to avoid damage or injury.

What Makes Garage Door Springs So Dangerous

Garage door springs aren’t risky because of what they look like — they’re risky because of what they do. These tightly wound coils carry the heavy lifting load for your garage door. That can mean holding the force of 150 to 400 pounds.

The real garage spring danger lies in the stored energy. When you open or close your door, the spring winds and unwinds, keeping the door balanced. If it breaks or slips under tension, that energy gets released fast — and dangerously.

Common risks include:

Springs snapping and whipping back
Tools slipping under pressure
Doors crashing down suddenly
Cuts, bruises, and even broken bones from unexpected recoil

Even experienced DIYers have been caught off guard. Each year, thousands of injuries are tied to the dangers of garage door springs, especially during untrained repairs. What’s more, when you’re working on a tight timeline — like many small business owners are — rushing through the job can make things worse.

What’s Behind All That Tension?

To understand why they’re so hazardous, it helps to know how a garage door spring works.

Most systems use either torsion or extension springs:

Torsion springs are mounted above the garage door and twist to create torque.
Extension springs stretch along the sides and expand to hold tension.

In both cases, the spring is doing the heavy lifting, so you don’t have to. When worn or misaligned, these springs lose balance. That’s when doors become heavy, lopsided, or stuck — and when people start trying risky DIY repairs.

When you’re dealing with parts that are under that much force, even a small mistake can lead to big problems.

The Problem with DIY Spring Repair

It’s tempting to think you can watch a video and handle it yourself. The reality is, spring repair is one of the most dangerous types of garage maintenance. Most property owners don’t have the tools or training to safely remove or install a spring under high tension. Here’s what commonly goes wrong:

Choosing the wrong spring size or type
Incomplete tension release
Injury during unwinding
Damaged brackets or cables during reinstallation

Aside from personal safety, incorrect repair can lead to more costly damage or total failure. A door that’s out of alignment may stop working altogether or even cause damage to the opener. In the end, trying to save a few dollars could end up costing you much more — in both time and medical bills.

Whether it’s a residential door or a light commercial garage door setup, the risks stay the same. And for spaces that rely on regular garage access — like workshops or auto shops — downtime from a botched spring repair can hurt business.
