I,myself,would not be without insurance.I work with tall ladders and all I need is to have one fall. I can,t pay out of pocket for repairs.Where I live,central Mo., the minimum policy is $600,000. For a little bit more I went with $1,000,000. I can pay the premium monthly. Steve is right with his thoughts.Carefull with electricity and plumbing.Having insurance helps ease the homeowners mind. After all, your working with his property.Good luck in business, Ron J.
