Mold Testing and Remediation questions, answered by experts

Mildew is a type of mold that forms in areas of excessive moisture and poor ventilation. Although it commonly exists in household air, it can’t take hold and spread if a surface is clean and dry. Generally, if you have any mildew or mold issues, it’s because the humidity in either your house, room, cabinet, or cupboard is above 50 percent. Common areas where you’ll find mildew are around water sources, which is why it’s commonly found near showers and in kitchen sinks.

Yes, mold under silicone caulk can potentially cause health issues, which may be more noticeable in people with asthma, allergies, or other respiratory conditions. Mold releases spores into the air, and inhaling these spores can cause symptoms such as coughing, sneezing, eye irritation, and skin rashes. It's important to address mold issues promptly to protect your health.

Beyond looking for visible signs of mold in a home, you can tell if your house has mold by undertaking testing. You can hire a local mold testing company to run the test for you, giving you a sure answer. Professional testing is often the best way to determine whether you have mold, as some types of mold may grow in places where you can’t easily see them, such as behind walls.

Although you can run a DIY test for mold inside your home by buying a test kit, you won’t know whether the strain of mold is dangerous. The best way to test for mold in a home is to hire a professional who can determine the specific type of mold that you have. If you’re worried you exposed yourself to mold and it’s making you ill, you could request a health test. Your personal doctor could test your urine, take a nasal swab, or test some body tissue to determine your potential exposure to mold.

Signs of mold under silicone caulk include discoloration or dark spots appearing through or around the caulk, a musty odor in the area, and visible growth on the surface of the caulk. Additionally, if the caulk feels soft or spongy, it could indicate moisture trapped underneath, which is a breeding ground for mold.
