"I can not say enough about Mark and his team. They were professional, empathetic, understanding and beyond reliable. They made a difficult situation so much easier and went above and beyond. They quoted me a price and stuck to the price and remained in constant communication with me the whole time they were working. I am so thankful I found them."

"Bio-One is a 10/10 recommendation for any situation. Whether you're moving, flooded, or just hoarding. They are a very empathetic company with employees who love what they do. I had the pleasure of being helped by Joel, and Gabriel who were very professional. They work really fast and efficiently, like I said previously 10/10 recommend !!!"

"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."

"We’re so grateful to Bio-One for the hard work they did helping us reorganize our house, sort through all our belongings and decide what to throw out, donate and keep to be used again. Both Mark and Charity couldn’t have been more professional and caring while helping us with this overwhelming task. Are so happy we did choose Bio-One and would not think twic..." Read more

"I walked into a situation that I knew was too much for me. It was an extreme hoarding situation and I was ready to just walk away. My husband found Mark and his team and I am now excited with the possibilities that come with this house. This team was a blessing when we needed it the most and I can not praise them enough. Great communication, passionate about..." Read more

"Couldn't be happier! I had a mouse infestation in the drop ceiling of my basement. I called for a quote and he actually pulled back some tiles and looked around. Then told me exactly what would be done. The quoted price is what I paid. It was more than half of what other companies were charging! They came in, removed all the tiles and cleaned everything! Did..." Read more

"I was 100% impressed! From the level of professionalism, the respect shown to us, the thoroughness of the work performed...I could not have asked for more. They held to the original estimate, both in price and time. The communication was clear and timely. I will definitely be using them again when I get to the basement!"

"We had to quickly prepare our hoarded home for my Mother-in-Law's hospice care. They were wonderful. Not only professional, prompt, and efficient, they were also just a joy to work with. They made a very emotional and frustrating process as painless as can be. I couldn't recommend working with them more. We've already scheduled with them again and they'll be..." Read more

"I highly recommend Mark and his amazing crew. They are very good at what they do. They are efficient and kind, which is important in a business where the people they encounter may be going through an emotional time.

"Mark is such a great person, when my family was in need and time was of the essence he was kind, compassionate and was able to accommodate our needs in the short timeframe we had. I was coordinating from across the country which can be tricky and a little nerve-wracking to trust people you have never met in person but we hit the jackpot with Bio One and Mark..." Read more

"I reached out to Mark about having our basement cleaned up from rodent droppings i discovered. He came by quickly and took a look and explained the process and sent an estimate soon after. He was very accommodating to my schedule and easy to work with. I appreciate a business that is responsive and professional. The basement looks great, thank you guys!"

"There are no words that can express my gratitude for their kindness and respect Mark, Charity and Chesley showed my Mom while decluttering, cleaning and removing 52 years of stuff. A seamless process over four (4)days and all we had to do was state what stayed and what was going. Thank you. I'll see you in Spring when we do the garage."

"Professional, efficient, and respectful. During a difficult time, we needed a deep/biohazard clean & floor removal in a short timeframe. Mark responded immediately and was meeting with us in person less than 12 hours later. He began the job (no easy feat) and worked tirelessly until is was completed far beyond our expectations. This all occurred within 24 h..." Read more

Mark and his Charity were phenomenal in dealing with her and understanding the challenges of dealing with someone who is dealing with a mental health issue. They were very professional and accommodating and supportive during the..." Read more
