"Marcos was friendly and fast, and flexible in scheduling. He and his crew did a great job for us in removing asbestos tiles from our basement flooring so we could have interior drain tiling installed. In the process, they also discovered some mold, which they were able to deal with at the same time. He came with a large crew, so they finished a large job very quickly. The space was well cleaned afterwards, and we received the necessary clearances. Highly recommend."

Mold Testing and Remediation questions, answered by experts

Toxic mold doesn't have a specific color; instead, toxicity depends on the type of mold and the mycotoxins it produces. Stachybotrys chartarum (also known as black mold) is notorious for its potential toxicity. However, not all molds appearing black are Stachybotrys chartarum. Mold species that appear in various colors, such as green, gray, brown, or black, can also produce mycotoxins. Therefore, it's essential to focus on identifying the type of mold through professional testing rather than relying solely on color to determine its toxicity.

Iron sediments from rusty pipes are not likely to cause health problems. While a glass of yellow-hued water is off-putting, it is generally safe to drink yellow water in the short term. But you certainly want to address this problem. In the meantime, switching to bottled water until the yellow water issue is resolved is a good idea. 

Black discoloration on your attic insulation may be caused by buildup from soot, dust, or dirt, which does not come with dampness or a musty odor. However, another cause of black discoloration on attic insulation is black mold, which has a musty smell and other signs of damage. If you’re unsure what black stuff you’re looking at, consult a pro to be safe.

The symptoms of mold exposure for sensitive parties include a skin rash, runny nose, coughing, sore throat, burning eyes, and even more severe allergic reactions. If you notice signs of mold exposure, contact a medical professional right away.

If you find black residue in your toilet tank, chances are it’s caused by manganese deposits from hard water and not mold growth. You can prevent these deposits from damaging your toilet by installing a water softener in your home, which also might improve the quality of your drinking water. You can also remove the deposits inside your toilet tank once every six months or so to prevent them from causing problems with toilet functionality.
