How to Adjust a Garage Door Spring: Safety Tips and Expert Advice

Published Date: Sep 23, 2025

If your garage door has started acting up — slamming shut, feeling unusually heavy, or refusing to open evenly — there’s a good chance your springs are out of balance. While it might seem natural to search for how to adjust a garage door spring for a quick fix, this job isn’t as simple or safe as it looks.

Garage door springs are under serious pressure, and even a small mistake could lead to injury or property damage. This article from Up & Down Garage Doors breaks down the signs your springs may be off, explains why DIY can be risky, and shows how professionals handle spring adjustments safely.

Signs You Might Need a Spring Adjustment (or Replacement)

It’s not always obvious when your garage door springs need attention. Recognizing early warning signs can help you avoid more expensive repairs later. Watch for the following:

The door feels heavy: Lifting it manually takes more effort than usual.
The door closes too fast: This means the springs may no longer be controlling the door’s movement correctly.
Uneven door movement: When one side moves faster than the other, it often means the tension is off.
You hear a loud noise: A sudden bang in the garage could point to a spring snapping.
Gaps or stretching: Visible separation in the spring coils or overstretched extension springs are clear signs of failure.

If you’ve noticed any of these problems, it’s best to stop using the door and have it inspected by a technician.

The Risks of DIY Spring Adjustment

There are plenty of tutorials that explain how to adjust garage door springs, but very few talk about the actual danger involved. Garage door springs are under hundreds of pounds of tension. If they snap during an adjustment, the recoil can cause serious injury.

Trying to fix it yourself, especially without the right tools or training, may lead to:

Injury from sudden spring release
Damage to your garage door or opener
Misalignment that causes uneven wear
Voided warranties due to unauthorized repairs

Even small adjustments to spring tension can be risky without proper tools. To understand more about the dangers of spring tension, it’s worth reading how these components work and why professionals take serious precautions.

What a Pro Actually Does During a Spring Adjustment

A trained garage door technician brings experience and proper tools to every job. When adjusting a spring, a pro follows a clear process to restore balance and ensure safety. This usually includes:

Inspecting the spring type and condition
Checking how much tension the door requires
Using winding bars to make controlled adjustments
Testing the door’s movement and weight balance
Lubricating hardware and checking the full system

Professionals also know how to adjust garage door springs safely, whether your setup uses torsion or extension springs. They can also tell whether an adjustment is enough — or if replacement is a better option.
