"**"Do not contact him?he?s a complete scammer and unlicensed. I was looking for an air testing service on Angi, and he called me. I explained over the phone that our newly renovated home had a strong chemical smell, so we wanted an air quality test. He said he could do it and asked for a deposit. About 15 minutes after I paid, I double-checked with him about the testing details, then he told me that he didn?t have the equipment to do the test. Then he refused to refund my deposit. First, he never mentioned the deposit was non-refundable. Second, the cancellation was entirely his fault?he suddenly claimed he couldn?t do the test due to lacking the tools. This is outright fraud: he took my money, won?t return it, and can?t even provide the service. I?ve already filed a complaint with the BBB. Everyone, beware of this scammer!"** "

Mold Testing and Remediation questions, answered by experts

Telling the difference between poisonous and nonpoisonous mushrooms is difficult even for trained mushroom experts and biologists! However, nature provides some red flags for poisonous mushrooms. Assume that any mushroom with a red cap or stem is poisonous. You should also assume mushrooms with white gills, rings, skirts, or a sack-like base are poisonous. 

Not all molds are inherently harmful, but their presence can lead to health issues, especially for individuals with allergies or respiratory problems. Black mold often garners attention due to its potential toxicity. However, other molds can cause health concerns too. Regular mold, appearing in various colors like green, gray, brown, or black, can trigger allergies and respiratory problems. Prompt removal and prevention measures are essential, regardless of mold type, to maintain a healthy indoor environment.

Rust in your bathtub occurs when iron in the water or on metal components in your tub are exposed to oxygen, but while it’s unsightly, it won’t make bathing dangerous. However, if the rust appears under or around your tub spout or shower head, it could indicate that you have high levels of iron in your water. Drinking water with small amounts of iron in it usually doesn’t pose a health risk, but you might want to consider installing a water softener. The presence of iron could indicate that you have hard water, which can create some plumbing issues.

While the air inside your home should have some moisture—the ideal humidity level is between 30% and 50%—too much moisture can lead to issues. Some ways to tell if there’s too much moisture in your home include condensation inside your windows, mildew growth in the bathroom or mold on surfaces, peeling paint, or an uptick in allergy symptoms.

Humidity, moisture, and a lack of ventilation can all cause mold to grow on surfaces in and around your home.
