mildew odor in bathroom
I've been noticing it for about 3 weeks. It is not coming from the shower or under the sink; I notice it in the toilet area, which is right next to the exterior wall (which is cement board covered with plaster), which has been showing some signs of moisture penetration at the top of the wall above the window. That was part of the reason for the new roof and gutter last year.
About 4 years ago I discovered that the wax seal of the toilet was leaking and had to replace rotten flooring. Would it have failed so soon?
I am wondering now how I can determine where the mildew smell is coming from (if I can) without or before ripping out the toilet or the wall. In other words figure out the location of the moisture so I know what to tear out. Is there some kind of device or method?
PS if you know anything about cement basement floors, look at my post in the basement forum. Seems I may have a moisture problem there too.
