My house smells like there is mold somewhere. There are no leaks anywhere and nothing is wet! We replaced the bathroom down to the studs and there was a smell there but everything is new now. When we go out for a few hours and come back... it smells strong and really moldy. Even my clothes that are in my dresser or in the closets smell. I have checked everywhere and I am very stumped. Any suggestions on what I can do to find out what is causing this?
