"I reached out after mold was discovered in our basement, and thanks to Amanda, we had an inspection scheduled a few days later. Ryan came out, assessed the situation and presented us a complete estimate including the mold removal as well as for all the repairs. Within a few weeks, teams came in and quickly removed the damaged areas and Brent did a very nice job with all the restorations! The teams from start to finish were all professional and we are pleased with the results."

Mold Testing and Remediation FAQs, answered by experts

The primary difference is that black mold (Stachybotrys chartarum) is considered toxic and more dangerous than regular mold. It can produce harmful chemicals called mycotoxins, which may lead to severe health issues like respiratory problems, skin irritation, headaches, and other long-term complications. While regular mold is rarely toxic, it can still cause allergic reactions and respiratory irritation. Visually, black mold often appears dark—green, gray, brown, or black—with a fuzzy texture, whereas regular mold can be almost any color. Black mold is less common and typically grows in areas with severe water damage. Regardless of the type, you should not ignore any mold infestation in your home.

Powdery mildew is exactly like it sounds—a widespread mold that looks like baking soda or talcum powder. It’s usually seen on plants and spread in warm climates, which is why many people first discover this issue in their home greenhouse. Over time, plants have become resistant, but if you see it spreading, baking soda and water can eliminate many cases. Otherwise, consider neem oil or fungicide. 

Mold doesn’t require much airflow to make it out from behind walls and into your living space, making you sick. HVAC systems can actually pull the mold from behind walls and spread it through your home. While the mold may be out of sight, moisture transfer from the wall can also spread the mold from behind the wall into your living space and air. Any cracks in the walls or bad insulation only compound this effect. 

Mold on windows forms due to excess moisture from condensation, poor ventilation, or leaks. Cold glass surfaces can attract condensation, especially in winter. High indoor humidity, lack of airflow, or dust accumulation are also contributors. To prevent mold growth, improve ventilation, regularly clean sills, and consider using a dehumidifier or sealing any leaks.

No. When dry, mold enters a dormant state. While “sleeping,” the mold won’t multiply, but when it encounters moisture again, it springs back to life, releasing spores. That's why it's crucial to not only control humidity but also actively eliminate mold to prevent its resurgence and further growth inside your home.
