We bought our house one year ago. Before we moved in, I painted cabinet doors... in the home on a sheet of plastic. When I pulled up the sheet of plastic, the carpet was ever-so-slightly damp. The previous owner had the carpets cleaned after they moved out which would have been at least a month prior. ANYWAY, now I am smelling a musty smell in the home. (It has been mild temperature-wise with no AC or heat running) I really don't know if it has anything to do with what I've described, but I don't know what to do. I would appreciate any advice!!!!
