"For the homeowners who discovered mold in their home, and are stressed and worried about the potential cost of the eradication process, you need not look any further than these guys! Craig showed up promptly on the day day and time of our appointment, and my wife and I were immediately impressed and comfortable with his warmth and knowledge! During his assessment, he took his time pointing out the obvious areas and certain problems we never noticed! He did this not to frighten or pressure us, but being informative about the reason for for the presence of the mold! But what shocked us was the total cost of eradication...it was almost half of what 2 other companies had quoted us! His crew of young men worked tirelessly and were friendly and courteous to a fault. No complaints about their cleanup efforts either! We would highly recommend this company in a heartbeat! Ray & Lisa Jones, Delaware, Ohio"

Mold Testing and Remediation questions, answered by experts

Powdery mildew is exactly like it sounds—a widespread mold that looks like baking soda or talcum powder. It’s usually seen on plants and spread in warm climates, which is why many people first discover this issue in their home greenhouse. Over time, plants have become resistant, but if you see it spreading, baking soda and water can eliminate many cases. Otherwise, consider neem oil or fungicide. 

The CDC does not consider diatomaceous earth toxic to humans or animals, though it can cause skin, eye, and lung irritation when handled without PPE. It's important to note that non-food-grade diatomaceous earth can be toxic when handled or consumed, so homeowners should only purchase the food-grade option.

If the smell is closer to mildew or rotten eggs, the issue is probably mold or bacteria buildup in the machine or its drainage system. Clean your washing machine thoroughly, paying close attention to the rubber door gasket, as it can harbor odor-causing residue. Some machines have lint or debris filters that should also be checked and cleaned according to the user manual's instructions. Be sure to leave the machine's door or lid open after each use, as this allows for better air circulation and helps prevent mold growth.

Yes, professional testing identifies mold presence and type, guiding effective remediation plans that mitigate health risks. By ensuring thorough removal and preventing recurrence, professionals help maintain indoor air quality and reduce potential health hazards.

If you see black stuff under your vinyl flooring, it’s probably mold. There is a chance it could just be dirt, dried-out adhesive, or slight water damage, but some of those are causes for mold growth, so you should remove it immediately anyway. In some older homes, it could be black mastic asbestos. If you think it could be this–you guessed it–call a pro.
