Bio-One of Madison decontamination and biohazard cleaning services


MadisonMold Remediation

Biohazards and hoarding can create an environment for mold growth. There's no need to risk removing it yourself. Let Bio-One of Madison remediate it for you.

You called the right 
team for the job.

Quick Action

It only takes 24-48 hours for mold to colonize. All that’s needed is organic material and water. Typically, excess moisture from floods, leaks, or poor ventilation will do the trick.

Mold is a natural substance that also loves warm, indoor environments. The fungus can get in through doors, windows, HVAC systems, etc. and usually plants itself where no one will see it:

  • Attics and crawl spaces
  • Under sinks
  • Near washer and dryer hookups

Mold can be hazardous. The impacted areas will need to be treated by a professional. If not removed properly, certain health risks may follow:

  • Respiratory complications
  • Skin irritation
  • Severe allergic reaction

Whether it’s removing surface-level spores or tearing down and reconstructing larger areas, it should be done professionally.

Quick actions once the mold is noticed will prevent a lot of damage. We can save you money on damages and the time it would take to repair them. 

Address the Source

Removal of the mold will only get you so far. It came in and grew somehow. At Bio-One, we address the source from which the mold came.

Any highly contaminated items will be disposed of. Our proper containment system will prevent any cross-contamination. However, mold will also be prevented from entering by the same means.

If you’re not addressing the problem, how much help can removal actually be? It’s sure to come back within 24-48 hours.

Angie and David helped us clean up our drop ceiling after we discovered the aftermath of a prior mouse problem in the house we purchased. They were extremely responsive and starting working on the issue immediately. It was a challenging job and they made sure that it was done with a high level of quality and attention to detail!

This company was absolutely amazing, from the quick response time to my inquiry to a remarkable clean-up completed the next day. Everyone I dealt with on the team was professional, compassionate, kind and discreet. The cost was completely reasonable. I unconditionally recommend Bio-One Madison to anyone needing clean-up services due to hoarding, extreme filth or other difficult cleaning situations.

Bags. Gloves. Dumpster. Elbow grease....apparent elements to practically all major clean-out tasks. Yet none of these elements would have been deployed (and the clean-out would not have transpired) had it not been for the more important elements that Bio-One provided. These less-apparent elements include things like tact, understanding and patience (and gentle, positive coercion) with the people involved who are often struggling with the various pressures of life. Have a big mess? Clean it up. Have something that's a little more than that...call Bio-One. Highly recommend this business and would not hesitate to employ them again.

I recently moved into a home that previously had a fairly substantial mouse problem, and worked with Bio-One to clean out the basement rooms that were favored by the mice, removing ceiling tiles & carpeting and disinfecting the worst areas. I contacted several similar companies in the Madison area, but Angie and David were by far the most responsive, quickly coming on site to provide a reasonable estimate. They were friendly & helpful throughout the process, and did a great job cleaning out the affected areas.

Angie, David and their team were incredible and helped us out immediately when we were in great need and on a very tight time schedule. They offer so many helpful services and were able to meet all of our needs the next day. They were kind, compassionate, caring, discrete and very good communicators. Their prices were so fair and they went above and beyond for our family. We are forever grateful for their services. If you have a hoarding situation on your hands that feels so overwhelming that you can't imagine how you would remedy it, call them, they are angels and can do it. Thanks again Angie, David and team!

David and Angie responded immediately and were onsite within 45 minutes in response to a death at home that resulted in serious decomposition. They are professionals who are well-equipped to thoroughly clean, remove waste, sanitize, and eliminate pervasive odor with ozone. They returned each day for 4 days until they and we were confident that their job was complete. They are a great team who does everything well to assure excellence. We highly recommend them.
