Tremendous service and worth every penny. They had a team out the very next day to address a big rodent dropping cleanup job. They went above and beyond and the final result was amazing.

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.

Besides the extraordinary customer service and professionalism, I am most grateful for Jermaine’s and Tony’s sympathetic manner. The entire Bio-One team went above and beyond to support our condominium community while managing an outrageous hoarding clean-out. Jermaine was in regular contact me and showed tremendous patience with the hovering mother still processing the horrific contaminated scene. Jermaine made two courtesy visits to accommodate the mother’s need to go through items and move heavy objects. Jermaine provided extra disinfectant, treated the area with an anti-COVID product and left an air purifier overnight to appease my smell sensitivity - all free of charge! I received 3 bids and Tony’s estimate was a significantly better value. I hope the universe responds in kind to their generosity - I HEART BIO-ONE!

"Recommend highly! We had a violent death in the family on Christmas Eve 2022. We initially called another biohazard clean up service with excellent reviews and their communication and response time were poor and inconsistent, adding more stress to an already horrible situation. We contacted Bio-One and Jermaine and Andre came out the SAME DAY we contacted them, within an hour or two, and started work immediately. They left the ozone machine running overnight so the next day when we returned there was no odor, no trace, nothing to indicate anything had ever happened. Everything was sanitized, all biohazard removed, and smelled like a normal house without chemical smells. We were (are) grieving and traumatized. Jermaine and Andre were so kind and professional. Their service took a load off of our shoulders. I don’t believe in angels but if I did, Jermaine and Andre would qualify. I will forever be grateful for their services when I needed them most."

    Mice were able to invade our house due to construction and set up camp in our pantry and garage. While another company provided the initial pest control and sealed off entry points, it was BioOne who truly saved us. It took me a few tries to connect with someone but once I did, they were incredible. They sent their tech out same day and he tackled the clean up (truly the hardest and worst part of our situation) with an extremely thorough disposal and disinfecting of our impacted areas. There was no way I could have done it myself and having the entire pantry and garage cleaned the right way brought a profound sense of relief to a situation that was not very tenable. Would absolutely use them again (I pray I never have to) and I would give them my strongest recommendation. Thank you so much BioOne. Truly.

    I was amazed how quickly I got a response from Bio One DC. I spoke directly with one of the owners - Tony Holloman. He was quick to understand my situation and that I needed a prompt resolution. Tony's professionalism and knowledge on how to help me was impressive. Thank you Tony!

    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 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.
