Mold Testing and Remediation FAQs, answered by experts

Mushrooms do not harm your yard. In fact, they can actually help improve your lawn health by decomposing woody organic matter in your soil, and breaking it down into nutrients that feed your grass and plants.

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.

Removing mold yourself can be dangerous. Always wear protective gear to cover your skin, face, and eyes, and wear a respiratory mask to protect your lungs. It is most recommended to only remove small areas of mold on your own and leave large mold growth to professionals. Mold growth can also be persistent. Without addressing the root cause, DIY surface cleaning can be ineffective and temporary.

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.

According to the EPA, mold allergies are common and can cause skin irritation, respiratory problems, headaches, and other allergic reactions. Mold allergies can also trigger asthma attacks in people with asthma. Additionally, some molds produce mycotoxins, which can lead to very serious conditions, like lung cancer.
