The color of the mold found in your home can vary depending on the mold species.

However, the substrate that the mold is actually growing on, the amount of water activity, and the amount of nitrogen on the substrate are determining factors in the color the mold also.  Yes, stachyboytris is the most well known toxic mold found, and it is usually black in color.  But it can also appear as white too. 

So don’t let the color of the mold cause you to make the wrong decision about the type of mold it really is. 

We use an independent lab to analyze your mold to accurately determine what type it is.  In addition to accurate identification, the lab also lets you know the known health effects from these molds.  Please consult a physician to determine if you have been affected by these molds.
