Your garage door is the heaviest moving object in your house, and the only reason you can lift it with one hand is a spring holding all that weight. When that spring lets go, it’s not a minor annoyance — it’s a genuine safety issue, and it’s one of the few home repairs where “I’ll just watch a video and do it myself” can actually get someone hurt.
Garage doors use torsion springs or extension springs to counterbalance the weight of the door. Every open and close cycle winds or stretches that spring a little more. Over time — sometimes years, sometimes just from a stretch of especially cold weather — metal fatigue catches up with it, and the spring lets go.
You’ll usually know the moment it happens. People describe it as a loud bang, almost like agunshot, coming from the garage. If that happens, don’t try to open the door. Without the spring doing its job, the opener has to lift the full weight of the door on its own, which can burn out the motor or, worse, let the door come down hard and fast with nothing to slow it.
This is the part where a lot of people get into trouble: replacement springs are easy to find online, and on paper it looks like a straightforward swap. In practice, winding a torsion spring means working against real stored tension with specialized tools, and getting the winding bar wrong even slightly can release that energy all at once. This isn’t a “worst case scenario” kind of warning — it’s a genuinely common way people get seriously hurt trying to save on a service call.
We carry replacement springs on the truck and can usually take care of it the same day you call. Beyond just swapping the spring, we check the cables, rollers, and tracks too, since a spring failure often means something else in the system has been under extra strain.
If your door suddenly feels heavy, won’t stay open, or you heard that bang, don’t try to push through it yourself. Check out our Garage Door Spring Repair page, or if it just happened, our Emergency Garage Door Repair page.
We handle spring repairs throughout the North Shore, including Mount Prospect, Wheeling, Arlington Heights, and Long Grove.
