Torsion Spring vs Extension Spring: Which Does Your Garage Door Have? (Northern Virginia Guide)

Torsion spring vs extension spring is a question every Northern Virginia homeowner should be able to answer because the type of spring system on your garage door determines how long it lasts, how much replacement costs, how dangerous a failure is, and whether an upgrade makes sense when the time comes. The short answer: torsion springs are mounted horizontally above the door and twist to counterbalance its weight; extension springs run along the side tracks and stretch. Most newer homes in Bristow, Gainesville, and Haymarket have torsion systems. Many older homes built before the mid-1990s still have extension springs. This guide shows you exactly how to identify which system you have, explains how each works, compares costs and lifespan, and tells you when upgrading from extension to torsion is worth it.
