We moved into our house 4 yrs ago and started by smelling beer and vomit and mold. I was smelling the walls for Chinese dry walls. Then I started smelling mildew and mold, now I am smelling sour smells like the garbage dump. Help please or am I imagining this. Thanks

Could this be from open windows or nearby sources outside the house? Have you looked for the source of the smells? Have you tried candles or aerosol sprays, or plugin scents? What kind of cleaning products have you used?
