What steps are involved in professional garage door spring replacement?

A professional secures the door, releases remaining spring energy, confirms the correct replacement size, inspects the shaft, bearings, drums, and cables, installs and tensions the spring, then balances and cycle-tests the complete door.

What to watch for

Secure the door and shaft before changing spring tension.
Match spring size to door weight and operating geometry.
Inspect cables, drums, bearings, and end plates before reassembly.
Finish with balance, travel, and safety-reversal testing.

Safety note: Torsion springs store enough energy to cause severe injury. This footage documents a professional procedure and is not a homeowner instruction to attempt the repair.
