"Responded immediately to the side effects of a water break in the house. Immediately restored electrical services to dry areas, came back a few days later to restore more services. Gave detailed proposal before work was initiated, had enough supplies on truck to immediately replace most of affected parts. and advised on purchase of replacement fixtures. The technician was cheerful and understood my goals in restoring service."
