Most helpful and thoughtful company! I called to ask for an estimate on getting a meth test done on my recovered stolen vehicle and the owners were so knowledgeable and kind! They gave me advice on the steps to take before getting the test done as to not waste my time or money on the testing. They were so compassionate and caring! HIGHLY RECOMMEND THIS COMPANY! :)

We are renting a house that was previously occupied by hoarders, so I contacted Gregg and his team at Bio-One to come out and look at the property. To my delight and surprise, Gregg was open and honest and let us know that his services were probably not going to be the most cost efficient for our needs - he recommended another cleaner and was honest about saving us hundreds, if not thousands, of dollars. While I didn't use Bio-One's services, I would recommend them 100 times over for their excellent customer service and best business practices!

This company did a remarkable job with decluttering, as well as deep cleaning my apartment. The employees worked quickly and efficiently, with great attention to detail. Very importantly, they were also compassionate, caring people who took pride in their work. I recommend them without reservation.

The team helped my family member tame two years of long-Covid clutter in two days. From our first contact with Gregg to the end of the process, we were treated with dignity and understanding. Our only regret is that we didn't call sooner!

We hired this company to provide a deep clean on a heavily vandalized unit to fantastic results! Prompt, professional service and the results speak for themselves.

Eric and Justin arrived on time, did a great job and were friendly and professional. Gregg responded quickly and was easy to work with. I would highly recommend BioOne to anyone.

This company is AMAZING!!!! When I had to experience one of the hardest days in my life, Gregg and his team of Jase and Eric were incredible. They came and helped to take care of something that I just couldn’t and they were so comforting. Not only were they kind, gentle, thorough, and helpful, they were also informative and professional. I was met with the utmost empathy and it made the worst day of my life able to be digestible. They hugged me, talked with me, let me get out my feelings and emotions while also keeping me level headed. I have told anyone that will listen I am so glad that I called this company above all the rest. It wasn’t just business to them, it was a compassionate encounter. In addition Gregg and Jase both called to check on me and my wellbeing within the following days and weeks as this was the hardest loss of ever! I couldn’t recommend a better group of people to help get through a horrible time. I appreciate them so much, I wasn’t a customer- I was treated as family. Thank you so much ❤️

They helped me cleanout a hoarding house that I purchased. When I contacted them they were able to start very quickly and had it completely done in 3 days. I really appreciated the quick service.
