Replacing garage door springs can be a challenging task, but with proper tools, safety precautions, and guidance, it can be done successfully. This guide will walk you through the process step-by-step.
Why Replacing Garage Door Springs Is Important
Garage door springs play a crucial role in counterbalancing the weight of the door, making it easy to open and close. Over time, these springs can wear out or break due to tension and repeated use. Replacing them ensures the door operates smoothly and safely.
Types of Garage Door Springs

Located above the garage door.
Wind up to store energy, which assists in lifting the door.
Extension Springs
Positioned along the sides of the door tracks.
Stretch and contract to support door movement.
Understanding the type of spring you have is vital before starting the replacement process.

Common Mistakes to Avoid
Using Incorrect Spring Size – Always measure before purchasing replacements.
Improper Winding – Incorrect winding can lead to poor operation or accidents.
Skipping Safety Steps – Failure to secure the door or wear protective gear can lead to injuries.
Not Testing Tension – Always test door balance and operation after replacing springs.
When to Call a Professional
If you are uncomfortable handling high-tension springs or lack the required tools, it’s best to hire a professional. Attempting this repair without experience can lead to serious injuries.
Maintenance Tips for Longer Spring Life
Lubricate the springs regularly with garage door lubricant.
Inspect for signs of wear, such as rust or gaps in the coils.
Test the balance of the door periodically by disconnecting the opener and lifting the door manually.
Replace both springs if one breaks, as they wear out at the same rate.
