Replacing both garage door springs at once is usually the smarter choice, even if only one has broken. The main reason is that both springs have typically done the same amount of work over the life of the door, so if one has reached the end of its service life, the other is often close to failing as well.

Installing one new spring beside one older spring can also create an uneven load. That mismatch can affect how smoothly the door opens and closes, and over time it may put extra stress on the opener and other hardware such as the cables, rollers, and track system.

It can also be more economical to replace both springs during the same service appointment. While changing only one may seem cheaper at first, the remaining older spring may fail soon after, leading to another visit and another labor charge. Taking care of both at the same time can help avoid repeat repairs and reduce the chance of future problems.
