You called the right team for the job

Gross filth often entails bacteria, viruses, and mold. These are harmful biohazards that must be properly sanitized and decontaminated. If left untreated, each will grow and become progressively more dangerous. At Bio-One, we have professionally trained cleaning technicians that remediate these kinds of problems for a living.

Bacteria & Viruses

Exposure to bacteria isn’t necessarily bad. Everything is covered in bacteria, it’s a part of our lives. However, certain forms and viruses can be harmful (Covid-19).

In light of this, we have gathered all necessary equipment and knowledge to sanitize and disinfect. We can decontaminate whatever gross filth needs cleaning.

Call Us 24/7
Compassion. Experience. Respect.

Mold

Mold doesn’t require much to colonize. 24 hours and some excess moisture typically does the trick. Whether we need to decontaminate the surface or remove pieces entirely, the job will get finished.

Each site varies in severity of mold and gross filth. The quicker you call, the less damage there will be. We are available to give you the best chance of stopping the spread.

If it escalates and something must be torn out, we will reconstruct it. We want to leave you with a comfortable, safe environment. Not a bunch of holes in the wall.

Community Outreach

At Bio-One of Madison, we work closely with the Madison, WI community to ensure a safe and clean environment. We strive to make a difference here.

For many years now, we’ve been proud to partner with local authorities, charities and other groups. We offer them the most up to date cleaning methods and techniques to keep our area safe.

    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!

    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!

    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.
