How to Replace Garage Door Torsion and Extension Springs

Guide to Replacing Garage Door Springs

Replacing garage door springs typically involves installing new springs after the old ones have failed. Springs are vital components that assist in lifting and lowering the heavy garage door, although they are separate from the garage door opener itself. Over time, weather elements weaken these springs, leading to breakage. Usually, springs break gradually, often one at a time, making the door difficult to operate and increasing stress on the opener. Proper replacement depends on the spring type and whether you plan a DIY fix or hire a professional.

Many homeowners discover their spring is broken only when attempting to open the door or noticing unusual noise and sluggish operation. During failure, the door becomes significantly heavier, resembling the weight of a truck. Springs break under tension or when fully loaded, sometimes producing a loud sound similar to a gunshot. The common types include torsion and extension springs. Torsion springs are mounted horizontally above the door and utilize twisting tension, while extension springs run vertically along the sides and need safety cables for security.
