Is your garage door not opening right? Maybe it feels too heavy, opens too fast, or doesn't stay in place. This can happen when your garage door spring is loose. Learning how to tighten garage door spring is a great way to keep your door working safely and smoothly. In this guide, you'll learn how to do it step by step.

What Is a Garage Door Spring?

Garage door springs help lift and lower the door. They carry a lot of weight, so they need the right amount of tension. There are two main types:

Torsion Springs: Found above the garage door. They twist to create tension.
Extension Springs: Found on each side of the door. They stretch and pull the door.

If the spring isn’t tight enough, your door may not open or close right. Fixing garage door spring tension is part of good garage door maintenance.

Signs You Need to Tighten Your Garage Door Spring

Knowing when to adjust your garage door spring is key. Look for these signs:

The door opens too slowly or doesn’t open fully.
The door slams shut or closes too fast.
The door feels too heavy to lift.
You see the spring hanging loose.

These are clues that it’s time for a garage door tension adjustment. Always be careful. Garage springs are strong and can be dangerous if handled the wrong way.

Safety First! What You Need Before You Start

Before adjusting garage door spring tension, gather the right tools:

Winding bars (never use screwdrivers)
A wrench set
Safety goggles and gloves
Clamps or locking pliers
A sturdy ladder

Safety is important! Garage door springs are under a lot of tension. If you don’t feel sure, call a garage door repair service.

How to Tighten a Torsion Garage Door Spring

Here’s how to adjust torsion springs safely:

Unplug the garage door opener and disconnect the door.
Open the garage door fully and clamp it in place using locking pliers.
Find the torsion spring above the door. Mark the current tension setting.
Insert the winding bar into the winding cone. Hold it firmly.
Loosen the set screws on the cone with a wrench.
Tighten the spring by turning the winding bar upward (usually one-quarter turn at a time).
Tighten the set screws again once done.
Remove the clamps and test the door. It should stay in place when half-open.

Torsion spring adjustment should always be slow and steady.

How to Tighten an Extension Garage Door Spring

Extension springs are easier to adjust:

Disconnect the opener and unplug power.
Open the door fully and secure it with clamps.
Find the extension spring along the side.
Move the S-hook or spring clip to a higher hole to increase tension.
Secure everything again and remove the clamps.
Test the door balance by opening it halfway. It should stay put.

Garage door spring calibration is easy if you follow each step closely.
