Commercial Spring Failure on a 10×14 Insulated Door

This vinyl-back insulated commercial door had stopped operating properly due to a worn and failing torsion spring. Insulated commercial doors are significantly heavier than standard residential doors, which means the spring system works harder and wears out faster over time. In this case, the weakened spring caused uneven lifting and unreliable door movement.

Our technicians carefully removed the damaged spring and installed a new, properly rated commercial-grade spring designed to handle the door’s size, weight, and usage frequency.

Precision Spring Replacement and Door Balancing

Once the new spring was installed, we fine-tuned the tension and completed a full balance test to ensure the door moved smoothly through its entire travel. Proper spring balance is critical for commercial doors, as it reduces stress on the opener, prevents premature component failure, and improves overall safety.

After installation, we inspected all key hardware, verified track alignment, and tested the door multiple times to confirm consistent, dependable operation.

Why Commercial Garage Door Spring Replacement Matters

Commercial garage doors experience far more cycles than residential doors, especially back doors used for deliveries, service access, or daily operations. Ignoring early signs of spring wear can lead to sudden door failure, safety hazards, and costly downtime.

Common signs a commercial door spring may need replacement include:

  • The door feels unusually heavy when opening

  • Uneven or jerky movement

  • Loud snapping or banging noises

  • The door won’t stay open or fully closes on its own

  • The opener struggles or stops mid-cycle

Replacing the spring before total failure helps protect both people and equipment.
