We Clean Tough Situations:
Washington DC Suicide, Crime Scene and Biohazard Cleanup

It's really difficult finding companies that do what Bio-One does. My wife hired them because we were getting worried about airborne Hantavirus from mouse feces. They were extremely thorough. They even cleaned carpets. This is a legit, full-hazmat team ready to take on what you can't. They were super easy to schedule and they came to our house within 2 days of calling them. Professional and highly effective. If you're debating the value, just do it. Hire them.

"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!"

Bio-One exceeded my expectations. I’m a property manager and needed to have a luxury condo disinfectd and made ready for a new tenant. Bio-One was able to come out and get the job done within two days. I will continue to use and refer Bio-One to family and fellow property managers. Thanks again!!

From the first time I spoke with Tony he assured me that he could help with cleaning out my deceased sister home. I was relieved because I never dealt with a hoarding issue before. And didn't know how to handle the issue. But working with Tony's cleaning crew was amazing from start to finish the cleaning crew treated me with the upmost respect and kindness doing the clean out process. I would recommend this company they do amazing job, great customer service. THIS IS ONE SATISFIED CUSTOMER!! Thanks again guys for a job well done.

"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 disinfectd, 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."

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.

Can’t thank the Bio One DC Team of Jermaine, Chad and DeWayne. Arrived on time, worked efficiently and effectively to solve our problem. Also, Tony was responsive and incredibly flexible in scheduling and ensuring everything was set for my appointment. Highly recommend Bio One DC.

When I found dead mice and mouse droppings in my garage, I had no idea who to call or where to begin to clean it up. Tony was incredibly helpful when he came by to take a look. His team came a couple of days later and carefully disinfected my boxes and moved them into a storage unit. They did a thorough cleaning of my garage all within a day. I highly recommend these folks for those jobs that you can't just hire a maid service for.
