"Robert explained a person who checks for mold cannot, ethically, remediate the mold. It would be a conflict of interest. I appreciated that information. He was thorough and explained what he was doing. Luckily, I did NOT have an air quality problem. I highly recommend his services."

"I know that I'm being picky but there were a few paint splatters left behind. But it was ceiling work so splatters are probably expected. Other than that the work was good and I am confident no mold will return. The work was also quickly scheduled and finished quickly."

Mold Testing and Remediation FAQs, answered by experts

The negatives of a humidifier are the potential for mold growth due to high humidity levels, the up-front cost, and the energy requirements to run it. Depending on the state of humidity in your home, you may not actually see lower utility bills due to the humidifier running on a near-constant basis. 

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.

Running an air conditioner with mold is not safe because it can spread harmful mold spores throughout your home. Exposure to these spores can trigger various health problems, including respiratory issues, allergies, coughing, wheezing, sneezing, itchy eyes, and a sore throat. It may also aggravate asthma in household members. Continued exposure can increase the risk of more serious illnesses like sinus infections, pneumonia, and bronchitis. If you suspect mold in your air conditioner, you should stop using the system until it has been properly cleaned to avoid health risks and further contamination.
