Understanding Garage Door Springs: Types and How To Replace Them

There are two main types of garage door springs commonly used in residential garage doors: torsion springs and extension springs. Each type of spring has its own design and function.

1. Torsion Springs

Torsion springs are installed above the garage door, parallel to the header. They are designed to store mechanical energy when twisted or wound tightly. When the garage door is closed, the torsion springs are under tension, and as the door is opened, the stored energy is released to assist in lifting the door. Torsion springs are typically made of high-strength steel and are known for their durability and ability to handle heavy loads.

2. Extension Springs

Extension springs are usually installed alongside the horizontal tracks on both sides of the garage door. They work by extending or stretching when the door is closed and contracting when the door is opened. Extension springs use the principle of elastic potential energy to counterbalance the weight of the door. They are often made of steel and can be found in different sizes and tension ratings depending on the door’s weight.

It’s important to note that garage door springs are under high tension and can be dangerous if mishandled or improperly maintained. If you need to replace or repair garage door springs, it is recommended to seek the assistance of a professional garage door technician who has the knowledge and experience to handle the task safely.

The specific type and size of springs required for a garage door depend on factors such as the weight of the door, height, and track configuration. Garage door manufacturers provide guidelines and specifications regarding the appropriate springs to use for their specific door models. Consulting with a professional technician or referring to the manufacturer’s recommendations is essential to ensure the correct selection and installation of garage door springs for optimal performance and safety.
