I've got a musky smell in kitchen, moldy smell in master bathroom that wifts through to my bedroom. I've had landlord come and inspect and have been told there is no leaks under house and opening behind bath tub appears to be dry. The smell seems to generate around tub enclosure in bathroom and under sink in kitchen. Again landlord has had repairman come in and once again cannot find out why there is smell. There is no sign of mice in house. Can you help?? Thanks
