    decontamination and biohazard cleaning services reviews
    Alyssa Phillips, St. George, 2/1/2024
    I am so grateful to Dallon and KC at Bio One. After losing a close family friend , they were there to walk with us to reclaim our loved ones belongings from a scene that we could not have faced alone. They were professional and compassionate and super knowledgeable about biohazard clean up. Id recommend them to any one who needs help in cleaning up a crime scene or a hoarding situation. They are the best. Thank you again gentlemen!

    Shout out to Dallin: awesome guy who worked hard to try to make the fridge not smell anymore. Was very knowledgeable about different products. Dallin left me with some cleaner and it’s amazing stuff. Definitely a good business to utilize for tons of different issues!

    Dallin is so professional and empathetic. I couldn't imagine a better person to help people through such a horrific time. He is a bright light in a very dark world. He was fast and extremely efficient. He did the most minimal damage he could while making sure the house was safe from biohazard. He went above and beyond to make sure the toilet flushed that I was unable to figure out. I absolutely recommend this company!
