Don't really know how to sort it out. The plumber that is doing a few jobs for us has spilt black radiator water all over the hall carpet when taking an old radiator outside. It's spilt onto 3 pairs of shoes too. He's tried to clear it up but that radiator gunk is stubborn stuff. What's the fairest thing to do? Nothing? Expect something from the plumber? House insurance claim (though my excess isn't cheap)?
