       Q. Mold on our vigas (southwest round beam). I would like to know if this type of mold is harmful and active? Attached are photos of the mold.

       A. Because of its bluish-green unique color, the mold growing on your home's support beams is likely to be Penicillium mold, the third most dangerous indoor mold. Only mold lab analysis can confirm the Penicillium species for sure. Any mold in elevated levels indoors can cause severe health problems according to the U.S. Environmental Protection Agency.
