Newbie Mistake? Repairmen and Damage

[Account Closed]

I own 2 single family homes and have had great tenants for two years. Just replaced my first tenants with a three-generation family. Walked the house before they moved in and after, everything great. They were having issues with a breaker so I sent out an electrician to check it. Next day I go over there and the vinyl floor in the kitchen has three huge gouges in it. One actually tore a quarter-sized hole out of the vinyl. Tenant says the electrician moved a trash compacter and tore up the floor. Service company says one of the tenants, a 90-year-old man, insisted on trying to move it himself and was shoving it and gouged the floor. So it's a he-said, he-said deal. I tend to believe the service company - sounds like something the old man would do. Here's my question: what should I have done differently? And what do I do now?
