"Marcos was friendly and fast, and flexible in scheduling. He and his crew did a great job for us in removing asbestos tiles from our basement flooring so we could have interior drain tiling installed. In the process, they also discovered some mold, which they were able to deal with at the same time. He came with a large crew, so they finished a large job very quickly. The space was well cleaned afterwards, and we received the necessary clearances. Highly recommend."

Mold identification, mold test kits and testing supplies. If you suspect you have a mold problem give us a call toll free and we can walk you through your testing options.

"The self-test product was as expected. The reports require additional research to interpret and understand, so seemed more targeted at professionals."
