"They wear masks and are all tested regularly for COVID, which I appreciated. I cannot begin to convey how difficult it was to get rid of the contaminated sentimental and irreplaceable childhood items at my parents' home, and they were so understanding and sensitive to the loss of the items. Their compassion made the process a lot easier for me. The home had been condemned, and due to how meticulous the report was, it was certified as habitable again. I felt like 911 Hazmat was on my side and there to help me, and I found that to be invaluable."

Mold Testing and Remediation FAQs, answered by experts

Yes. Musty smells in your home usually signal that mold or mildew is lurking somewhere. Both can cause allergy symptoms in those who are allergic. Mold can cause structural damage and serious health issues if left unaddressed.

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.

Black mold often smells musty, stale, or earthy, and some people liken its scent to that of sweaty clothing. While not everyone can identify the smell of mold, you are likely to smell it before you see it, as it usually is hidden in dark, damp areas; instead, the scent may pervade your entire home. If you smell mold, start by opening windows and looking for the source of the smell. If you find mold or are concerned about side effects, call a mold specialist right away, as it can be almost impossible to get rid of yourself.

Mold is not guaranteed to grow on wet drywall, but the risk increases significantly the longer the material remains wet. Mold and mildew can begin to grow in as little as 24 to 48 hours, especially in optimal conditions, which include moist, dark places with temperatures between 77 and 86 degrees Fahrenheit. If the drywall is too wet to dry within that timeframe, mold can grow and spread. In any instance of water damage, it is wise to get a mold inspection to be certain that none has taken up residence in your home.

Poor maintenance can cause some health concerns, although these are more common in commercial misters than residential versions. For example, stagnant water can become a breeding ground for bacteria, some of which can be dangerous to human health, especially when inhaled. Regular flushing of the system before seasonal use should prevent issues like these.

Otherwise, avoid using mosquito misters with pesticides or plant misters with fertilizers near humans. These misters are not designed for cooling sprays around decks or patios, but for more utilitarian purposes.
