"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

Unfortunately, asbestos is not easily identified and can often be hidden in plain sight in your home. While it can look like fluffy fibers, tiny pieces can also appear in materials like plastic or cement, making it impossible to identify on your own properly.

Plus, since asbestos is so dangerous when disturbed, you should never root around to try and find it. This job is best for a professional who can test for the material properly.

No, heated floors are unlikely to cause mold. In fact, they can help prevent mold growth. The additional heat helps dry excess water and reduce condensation, which can lessen the likelihood of mold growth. Additionally, the heated floors can help reduce humidity near the bottom of the floor.

Visible growth, musty odors, and water damage are common indicators.

There are two types of mold symptoms in the home: visible mold and unexplained health issues. If you have allergies out-of-season, brain fog with no other obvious cause, constant congestion, and other such symptoms, you may have a mold problem. Oftentimes you can smell mold in your home, even if you can’t see it. 

While the air inside your home should have some moisture—the ideal humidity level is between 30% and 50%—too much moisture can lead to issues. Some ways to tell if there’s too much moisture in your home include condensation inside your windows, mildew growth in the bathroom or mold on surfaces, peeling paint, or an uptick in allergy symptoms.
