    decontamination and biohazard cleaning services reviews
    Kristi Woodward, Madison, 5/1/2025
    This company is amazing. They answered my call on a holiday and came out the very next morning to take care of my cleaning needs. Very responsive, professional, and kind. Highly recommended!
    decontamination and biohazard cleaning services reviews
    Kathleen Davis, Madison, 5/1/2025
    I can’t say enough wonderful things about Bio-One. I was in a crisis situation and I needed assistance quickly. I called Angie at 1:15PM on a Saturday afternoon and she met me at 2:30PM at the location I needed cleaned. The team was absolutely amazing and put me so at ease. The job the team did was so fantastic that because the work they did, we were able prevent the occupant of the apartment from being evicted. Without the help of Bio-One, this person would have lost their home. I would definitely give Bio-One a 10 out of 10 rating. Their compassion and patience was exactly the help I needed. If I ever found I need to hire someone for a difficult job again, Bio-One would be the first company I would call without hesitation!
    decontamination and biohazard cleaning services reviews
    Carie Myers, Madison, 5/1/2025
    I contacted Bio-One to assist with a biohazard clean-up in my home. I called them about 7:00 a.m. They were to my house before 8:30 a.m. and their work was finished before 12:00 p.m. on that same day. They were professional, efficient, and very sensitive to my circumstances. They took the initiative to submit their invoice directly to my insurance company, saving me time and administration in doing so myself. They also followed up with me a few days after their service to coordinate additional services needed to return my home into it's previous condition. I highly recommend Bio-One - they were true professionals with the needed compassion to get me back into my home as soon as possible.
