I am selling my home and the buyers sent over a home inspector to do the routine inspection. Well I got the report and he said that on the interior of my electrical panel the wires had some drywall mud covering some of the wires and some connections. Per his report "Clearing of mud is not allowed, replacement is required". How in the world would I replace all the wires in the house. Is it normal to recommend to replace all the wires for this??
