How a Spring Gap Develops
Torsion springs are wound tightly around a shaft above the garage door opening, storing energy that helps lift the door each time it opens. Over years of daily cycling, the metal fatigues, and a coil can crack or separate, leaving a visible gap where the coils no longer sit flush against each other.
In Huntsville's mix of humidity and temperature swings, springs can corrode internally even when the outside looks fine, which sometimes causes a gap to appear suddenly rather than gradually. Once that gap forms, the spring's ability to counterbalance the door's weight is reduced or gone entirely, so the door may feel far heavier than usual when raised by hand.
What Causes a Spring Gap to Form
Several everyday factors contribute to spring fatigue over time, and understanding them can help you plan for maintenance before a full break occurs.
Torsion springs are rated for a certain number of open-close cycles, and doors used many times a day tend to reach that limit and show wear sooner.
Moisture in the air can lead to surface rust that weakens coil metal from the outside in, making a gap more likely to appear without warning.
A spring that was sized incorrectly for the door's weight tends to work harder on every cycle, accelerating fatigue and coil separation.
Dry coils create more friction as they wind and unwind, which adds stress to the metal and can speed up the formation of a visible gap.
Is a Spring Gap Something to Worry About?
Not every gap means immediate danger, but most cases call for caution until a technician can look at the door in person.
Door Won't Budge
If the door won't lift by hand or with the opener, the spring has likely lost most of its tension and the door should stay closed until it's inspected.
Door Feels Heavy But Moves
A door that still opens but feels noticeably heavier than normal may have a partially failed spring, and continued use can add strain to the opener.
Loud Bang Was Heard
A loud pop or bang from the garage often means the spring broke at that moment, and a gap should be visible on inspection of the coils.

Get a Second Set of Eyes on Your Spring
If you've spotted a gap or your door is behaving oddly, sending a few photos and details helps our team give you a clearer picture of what repair options might look like for your home.
What Happens During a Spring Inspection
A technician typically starts by looking at both springs on the shaft, since one gapped spring often means the second is close behind due to similar wear patterns. They'll check the cables, drums, and bottom brackets as well, since a spring failure can put extra stress on those parts during the moments before it broke.
From there, you'll usually get a rundown of what's involved in the repair, including whether one or both springs need replacing and how the cables and hardware held up. Final pricing depends on diagnosis and scope, so ask questions about what was found before deciding how to move forward.
