    decontamination and biohazard cleaning services reviews
    Leah Witt, Green Bay, 12/1/2024
    Bio-One came to clean my basement today after we found a significant infestation of mice when we moved in. Brayden and his helper were polite, professional and got right to work. I feel confident that my space is clean and they even took away my bulky trash. I would definitely call them again, but I hope I don’t have to!

    Tim has helped take a large weight off my shoulders at a very unfortunate time. I would not only make him my first call in the future, if his services are ever required again he will be my only call. Thank you Tim, your handling of my needs have been very professional and highly appreciated
