AMAZING COMPANY! I called for an estimate and walk through and Angie and her team went out within 1-2 days. Very professional and quick to respond. She did such an amazing job. The apartment she worked on resident was possibly facing eviction due to high amounts of clutter and garbage. Though Angie and her team did such an amazing job, the tenant is no longer at risk of eviction! HIGHLY recommend.

Angie and David took the time to problem-solve and help with resources for a family member living in Northern WI. They offered to (literally) go out of their way to set up a cleaning if another company was not available. Ultimately, I found a closer service, but I wanted to be sure to highly recommend Bio-One for their helpful, timely, and compassionate assistance.

David and Angie were real life savers for my niece who has special needs. They were responsive to our calls and questions. I new I could not do it and when I found them and talked with them, I knew I had found the right team. David and his team arrived on time and worked so hard to restore her apartment to a clean safe environment for her to live in. My niece was treated with kindness and respect and participated in the decisions on what to keep and what to throw away. I highly recommend them.

Angela and David were amazing. From the beginning they were caring, passionate, returned my calls right away and answered my questions. They were able to come take care of the apartment within 48 hours of me calling them. Very great company. I would highly recommend Bio-One!!!

    I cannot begin to put into words the satisfaction we have with the services provided by David, Angela, and their entire Bio-One team. From the moment we called them to discuss our needs in helping to clean out a home due to a death of a loved one, to the day the final steps were completed to put the property back in order, they were so easy to work with. Not only are Bio-One's service impressively comprehensive, but they do their work in such a compassionate way. Their communication is among the best we have ever experienced from any service provider. We cannot recommend them highly enough. Rob & Dawn Lefeber

    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!
