Suspicious mushroom smell
We have strange smells in our house -- onions, mushrooms, and regular old ordinary mold. Does anyone know if the mushroom smell means we have a particular type of rot? Our basement has been wet for years, and is clearly a source of all of these smells. But it appears we may also have a problem in one of the bathrooms and possibly the attic as well. AFAIK there are no leaks in those areas. We've been all over the house with walls and ceilings open, and we've never seen anything obvious such as a mushroom growth. There are what appears to be white water stains on joists in the bathroom. We are working to dry out the basement and have it professionally cleaned. Do we need to have the basement and other areas of the house checked out by a fungus/mold expert? Would they be able to find anything? Do we need to use wood preservative? Thanks.
