Our contractor had not been cleaning up or vacuuming his remodeling mess on our first floor renovation which included a kitchen remodel. He kept insisting the only way he could work was for us to start putting things away in the kitchen, but the drawers and floors were filled with sawdust. I asked him if he were going to do this and he ignored me. I finally did it myself and destroyed my 800 vacuum not knowing one should only use a shop vacuum which he had in our garage and never told us. Is he liable for our ignorance? Also, one of his workers broke our toilet tank lid, is he liable for this. He is insured. We don't want to start anything. Are we covered for these losses?
