Absolutely love this company! Not only are they great at what they do, but at a time most businesses are price gouging, this team remains honest. They made a difficult time easier. They are respectful and go above and beyond. I would recommend them to anyone that needs the services they provide. You will not be disappointed.

Mark, Charity, and everyone at Bio One have been unbelievably kind, quick, honest, collaborative, and hardworking as they've helped us clean out a deeply hoarded house. I don't know what we would have done without them! I can't believe that within less than a week's time, they were able to come out, assess the job, and clear everything out as well as they did. They handled the job with such integrity and care knowing how difficult it is to tackle a job like this.

Mark and his team helped me with a very difficult situation this past week with my sister who was living in an apartment in squalor and was a hoarder. He was so compassionate and was truly an angel. He came to me the next day with his team and cleaned out her entire apartment and helped me right before a major holiday. I cannot express enough gratitude to him. He is amazing at what he does.
Barbara Kaplan
From my project's intake to its completion, Mark was prompt, professional and thorough. He contacted me right away after I left an inquiry through his website, assessed the job in a timely manner, gave me a very reasonable price and then tackled it with skill. It's never a pleasant thing to need this type of service, but Mark made it so much easier with a unique combination of compassion and focus.
Jeannie O'Sullivan
I chose Mark and his team because the reviews were so compassionate. I had a mess that I need professional help for. Mark and team never once made me feel embarrassed. They did a great job, on time and on budget. If I ever have such a mess again, Bio One be my first call.

    Bio-One Trenton did excellent work for our family. They work very hard and are very knowledgeable and skilled at the work. They kept us informed and were very sensitive and kind with emotional issues that came up about decreasing our belongings. After they cleaned, the rooms looked far better than I thought was possible. The Bio-One Trenton staff were exactly right for us. I completely recommend them and if I ever need these services again, I would always hire them.

    Exceptional service and compassionate professionals! Used Mark and team for significant rodent dropping cleanup of entire condo. From the first call and quote through the final clean-up, they gave me a tremendous sense of relief and reassurance in an extremely difficult situation. Superior attention to detail and commitment and discretion. No need to look any further!

    From my first phone call to Bio-One of Trenton, I felt understood and well looked after throughout the difficult cleaning up process of my client’s roach infested hoarded apartment!!! The team leader and his team could not have been more professional or thorough as well as punctual throughout. I highly recommend Mark Bonanni and his Bio-One team!

    Mark and his crew did a fabulous job. I got a response from Mark the same day that I called. Within four days he went to the job site and delivered a quote. Mark cleaned a four bedroom hoarded house. He arrived on time and never left early . he and his crew were honest enough to inform me of some valuables that were found. very appreciated. would not hesitate to hire him again.

    I needed a deep cleanup for one of my bedrooms. I contacted Bio-one and Mark immediately got in touch with me to schedule my cleanup. He immediately made me feel comfortable with my situation where a company that I contacted before him did not. He came out within days and did an amazing job. They were quick, efficient , pricing was good, and they put my anxiety at ease. I would HIGHLY recommend them!
