Mold Testing and Remediation questions, answered by experts

In some cases, yes, insulating an unheated garage can lead to mold and mildew. The issue with insulating a garage is that the interior will warm up and cool down more slowly than the exterior air, which can cause condensation inside the space. Where there is moisture, there is likely to be mold and mildew over time. Installing a vapor barrier can help avoid moisture and mildew problems in an insulated garage.

Frequently, fungi have a gray color with a powdery or fuzzy texture on a wall. In showers, fungi and mildew may resemble a pink slime. Meanwhile, toxic mold may resemble a fuzzy growth on walls that’s often black or green in color. Some toxic black mold will have specks of orange or white on it. However, not all dark-colored mold you find on a wall is toxic. An infestation of toxic mold often will spread faster than fungi on walls. If you are unsure whether you have toxic mold, reach out to a professional for help.

While metal ducts are known for being the most durable choice, flex ductwork is a safe alternative with a host of additional benefits. The key to installing flexible ducts is to make sure they’re properly sized and installed. For optimal results, it’s always best to hire a duct installation pro who has extensive experience with flex duct installation.

Hiring a professional for mold and toxic material testing ensures precise identification of harmful substances within a home. Professionals utilize specialized equipment and techniques, providing accurate results that inform proper removal strategies, safeguarding occupant health.

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.
