"We spent some time live with molds and we don’t know it was mold. We are trying 2 times to clean it out with some cleaning companies, but it was useless. Finally we got lucky with Bio 911- very professional, sharp, deeply attentive for details, even for our lifestyle depending on appearance of mold and compared with other not expensive. Thank you very much for Bio 911 and personally Kirill for outstanding work."
