"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

Results typically come back within 48 hours, allowing for prompt remedial action.

Any unexplained smell in your house should be investigated. However, some home odors are "red flag" worrisome because they pose immediate health and safety risks. Odors should be taken seriously when accompanied by headaches, nausea, or lightheadedness. If you smell an egg-like aroma, this is probably natural gas. You should leave the home immediately, and  contact your gas company.  

Some mold can look like dust, but most doesn’t. Powdery mildew is often confused with dust as it’s a similar color and grows in a similar way. Some gray molds can look like dust as well, but usually, it’s pretty easy to spot the difference. It’s better to be safe, so if you aren’t completely sure what you’re seeing is dust, call a mold professional to check it out.

Mildew is a type of mold that forms in areas of excessive moisture and poor ventilation. Although it commonly exists in household air, it can’t take hold and spread if a surface is clean and dry. Generally, if you have any mildew or mold issues, it’s because the humidity in either your house, room, cabinet, or cupboard is above 50 percent. Common areas where you’ll find mildew are around water sources, which is why it’s commonly found near showers and in kitchen sinks.

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.
