We're ready to serve you!

These guys could not be more professional. They came and surveyed our area that needed cleaning, which was in atrocious shape and smelled awful. Within a few hours we had an estimate and by the next day they cleared our whole basement room. The space is so clean you almost can't recognize it, they took all the junk with them and disinfected the area. AMAZING SERVICE

Bio-One! Outstanding service! Left an email at 1am. Tony called at 9am and within a couple hours Lawrence was at my door helping me with all my home needs. What an incredibly efficient business! Everything was handled seamlessly from the initial appt request to outperforming the work my basement required. This company gets an A++++. Tony and Lawrence thank you very much! Very happy with the service.

I contacted Bio one DC to come clean my elderly father’s house due to an infestation of mice. I first met with Tony. He is very personable and professional. Today 5/12/22, Lawrence & Jermain came to do the job. They arrived at the designated time. They were fantastic! Very professional. They did an absolutely phenomenal job. They even did the dishes. They cleaned and moved furniture. I am very satisfied and thrilled that they came and took care of the house. I absolutely recommend Bio One DC.

I called Bio-One on a Sunday to inquire about having a bathroom that had extensive sewage contamination from a toilet backup that was discovered weeks later. Tony was extremely responsive and professional assuring me that Bio-One could handle the job. Tony was even willing to try and schedule the job the same day, however I ended up opting to schedule the appointment on a subsequent day. Tony called me the next day on Monday to see if I was able to have the job done later that day. I agreed. Tony promptly confirmed the name of the technician and his time of arrival. Jermaine, the technician was prompt, professional and his work was thorough. He came in and tackled the job working diligently until the affected areas were thoroughly cleaned and disinfected. While I hope I won’t need this kind of service again, Bio-One is without questions a top notch operation when it comes to hazardous clean up. Five stars for Bio-One.

Fast and prompt service! Great job Tony!!

We had a house where the owner was a hoarder. Every room in the house was completely full!! We were overwhelmed. We called Jermaine with Bio-One and he was the epitome of great customer service. All the employees were great to work with and very friendly. In the end they did exactly what they promised and the house looked amazing. Thank you to Jermaine and the crew!!!!

Lawrence and Jermaine were awesome! They were on time and handled everything with care! They were extremely friendly and professional! They were called to clean rodent feces out my storage unit due to an infestation at the facility which they handled with ease. I would use them again but let’s hope I do not have to :-)

Tony, you did great setting this up on a near-emergency basis, and the job was successfully completed in one day as promised. Don't know if you know, but the crew didn't finish until 9:20 pm--a very, very long day. I want to take this moment to sing praises of Revis and his crew. Revis was an absolute monster to get the job done to my satisfaction, asking me over and over in the evening if the cleanup met my expectations. It did, and then some. Also, he was instrumental in helping me find various objects and boxes buried in the pile of debris in the rooms, setting them aside for me to examine. I asked him to do this, not expecting much success, but he was very thorough in setting things aside for me. Can't say enough good things about him, and his crew!

Not from Washington DC I was overwhelm and needed help badly.. They came to help when they had a full schedule.. They cleaned, disinfected, disposed of anything that was of no use.. I recommend them for the outstanding job that they did on my Aunt’s House..

We recently moved into our new home and found mice in the garage. I called a pest control company and then looked up a company who could decontaminate under the garage shelving. Bio One quickly responded to my inquiry and coordinated a time to come out once we got the all clear from the pest control rep. They provided prompt, professional service and now I can use my garage without feeling queasy. I would highly recommend them if you need a space professionally decontaminated.
