"They were awesome. And cheap. I added $25 to the check because they were so great. They only identify the problem not fix it. That keeps them honest. And makes sure the remediation company doesn t tell you the problem is bigger to charge you more."

Mold Testing and Remediation questions, answered by experts

Black mold on wood is a very serious issue. Besides compromising the structural integrity of the wood, it poses significant health risks. Stachybotrys chartarum, commonly known as toxic black mold, produces mycotoxins that can lead to respiratory issues, allergies, skin irritations, and other health problems. If left untreated, it can spread rapidly and compromise the structural stability of the affected wooden structures. Immediate remediation and preventive measures are essential to mitigate the risks associated with black mold on wood.

Mold can be hazardous to your health. Some people are allergic to mold and experience a reaction when exposed to mold spores. The reaction varies from person-to-person, but can include a runny nose, skin irritation, and asthma attack. Mold can also be irritating to people who aren't allergic, causing respiratory, skin, and eye irritation. In some cases, mold exposure can lead to infections.

Sewer gas in any location can cause eye and respiratory irritation if you’re exposed at low levels, or more severe symptoms if you’re exposed at high levels—but fortunately, the fresh air outside means it’s less likely to affect your physical health. However, sewer smells outside can still indicate significant plumbing problems that will need to be dealt with, such as a potentially damaged sewer line or roof vent pipe.

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.

Follow recommendations for removal or remediation to ensure a safe living environment.
