Describe the change
Mention a sudden bang, a visible gap in a spring, or a door that no longer rises normally. You do not need to handle the spring or measure it yourself to request help.
Get a complete explanation
Ask which spring system your door uses and what the proposed replacement includes. The technician should explain the condition of the system and why the selected components suit your door.
Ask about the return to service
Before the job is complete, discuss the checks performed, how the door operates and the care recommended for your equipment. Keep the service record and written terms for future reference.
