The young man who cleaned my car was polite and thorough. He patiently listened to my issue and answered all my questions. He explained everything he was going to do. Great job!

I had a very positive experience with Bio-One DC. Everyone I dealt with was professional and kind. They were extremely responsive and did an amazing job and offered to do extra tasks to help us out. While they were in the unit, they would FaceTime to ask questions to make sure they understood what we wanted and show us the progress they were making. The finished product was better than expected. I would highly recommend Bio-One DC to anyone looking for this type of cleaning service. I want to give a special shout out to Jermaine, Lawrence and Tony who made a difficult time less difficult.

With COVID-19 and increased rat presence, while we do have a rodent control contractor, but the rats became relentless with waste all over our patio Bio One was very responsive, coming in less than 24 hours and extremely thorough, cleaning the waste and disinfecting everything from the patio tiles, artificial grass, patio furniture and more. It now smells super clean and actually gave our patio a spring cleaning! Haha. Thank you! Highly recommend.

I can’t begin to express my gratitude to Tony and the Bio-One DC team. I came to DC to begin the process of handling my late Uncle’s estate and belongings. I was more than a little overwhelmed at the condition of his apartment and the sheer volume of “stuff” it held. I called Tony on Friday night and he had a crew meet me Saturday morning. Lawrence and Jermaine were incredible! They were friendly, compassionate and more than prepared to handle the task at hand. I’m still amazed at the difference after they spent the better part of their Saturday (6 hours) tackling the chaos. They were incredibly efficient and did an amazing job. I highly recommend Tony and team.

The team was on time, smart, caring, compassionate, efficient, experts at cleaning and disinfecting everything. I had become a hoarder and three months severe back pain prevented me from keeping my place up. It was awful but I felt no shame with the way they handled things. They restored my apartment to being spotless and clean for a healthy living environment as I recover from my spinal fusion surgery. They even found my missing Apple Pencil. I have a new life thanks to them. I cannot recommend them more.

I called Bio-One spoke with Tiny regarding a dear friend's residence without hesitation he explained his company process and said not to worry they could make a difference. I had to write an endorsement for the work this team of men have done; to endure such an undertaking with compassion and encouragement all while diligently purging three levels within the home. Afterwards coming back and sanitizing each area. Not once did I see a look of disgust. Total professionalism exhibited. Tony gave recommendations to continue maintaining a more healthy living environment. If you know of someone in need of this type of service be a friend provide the support and call Bio-One (Tony) will provide courteous professional service. On behalf of my dear friend Thank you so much. Continue doing exceedingly bless work. Ms.G & Robert

I called Bio-One DC and they were able to send someone the next day to clean up my storage room. The technician called ahead to make sure I was aware when she would come. The technician did a great job cleaning the room. She spent time checking all the areas in the room. At the end, she also gave me some tips on avoiding the problem in the future.
