Mold; if I can smell it, why can't I see evidence?

[rwand1]

Cardboard, fabrics, clothing etcetera can give off mildew smells and pick them up, particularly damp basments, poor air circulation, cluttered basements, hockey equipment, et ceteras. Moisture will migrate through concrete floors in the form of water vapour.

Hello Mr. Connell,

I guess the long and short of it is, does it matter whether the source is mold fungus or soil-borne bacteria? Is the typical recommendation for both, not sampling, but to correct the source of moisture?

They still have a bad smell and I still can't find a source of active moisture intrusion, but since the smell is there there must be moisture present which is encouraging the growth of either fungus or bacteria. Right?

So if I can't find it, it must be time to take invasive measures. Would I recommend this be undertaken by an Industrial Hygienist or might a mold remediation company be capable of dealing with it at a lower cost?

Should I recommend sealing penetrations and cold joints in the slab as is typical with Radon mitigation?

Is there a difference in recommendations depending on whether the source of the smell is mold fungus or soil-borne bacteria?

Would this house happen to have a sump pump or any floor drains?
