"**"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

Dog vomit slime mold is not toxic to humans, plants or pets. However, it can act as an allergen to people with allergies. Dog vomit slime mold is considered more of a cosmetic nuisance. However, it is beneficial to its ecosystem as it helps break down organic matter, releasing nutrients for plants.

Common causes include water leaks, settling, and impact. Address underlying issues to prevent recurring damage.

Most mushrooms found on residential lawns are harmless. Certain varieties such as destroying angel, fly agaric, and vomiter mushrooms that can grow in grass will occasionally make their way onto residential lawn, but this is uncommon. Since mushrooms can be notoriously difficult to identify, if you suspect that your lawn mushrooms could be a poisonous type, consulting a professional is recommended.

The most common sign of a carbon monoxide leak is the visible black soot marks on the walls near your wood stove. An excess accumulation of smoke in other rooms of your home could also indicate that your wood burning stove is leaking carbon monoxide. If you notice either of these signs or are still unsure, it’s best to leave the premises and contact your fire department to check your home’s levels. 

Mold in a basement is harmful as it can trigger allergy symptoms, especially for those with asthma and other breathing conditions. Symptoms of mold exposure include itching, sneezing, running nose, and congestion.
