Haven't seen any signs of leaks Been looking at older coaches and some of them are just musty smelling. Can these be cleaned up or is the smell so deep its there forever? Is it usually in rug...
Companies like ServePro, use ozone generators to remove odors after fire and flood damage. Used properly they will remove the odors so they do not return. I have used them on new construction commercial buildings to remove the odors from paint and other things that may affect people with allergies.
