Mold Testing and Remediation FAQs, answered by experts

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.

Yes, it is generally unhealthy and can be dangerous to live in a damp basement. The damp air can negatively affect your breathing and lungs, and the moisture promotes mold growth and pest infestations. Inhaling mold spores or waste particles from insects and rodents attracted to the moisture can be hazardous. This damp, moldy air can also circulate into your main living area. It is crucial to resolve any moisture problems and implement preventative measures before using your basement as a living space.

Usually, when you have mold, you will notice that your indoor air quality isn’t what it should be. You might notice dank odors, for instance, coming from your carpet, and it may feel damp or spongy. Or you may find that your family members are showing more allergy symptoms than usual, from coughing and sneezing to itchy, watery eyes.

And, of course, if you’ve recently experienced flooding or you live in a particularly humid environment, that’s a good sign you’re at risk for mold growth.

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.

Pressure-treated wood offers some protection from the elements but doesn’t protect against mold. However, if you spot mold growing on pressure-treated wood, it doesn’t indicate rot or an interior fungal infection—the treatment process ensures that the mold stays on the exterior. Keep the wood dry, but if you spot some mold, remove it immediately and clean the area.
