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!

Bio 247 LLC D/B/A Bio-One DC - 10/2021 - 5 star +++ service and rating! Bio-One is a firm specializing in extreme cleanup services. They helped us deal with a family member’s home that had level 4 hoarding and extreme infestation by cockroaches and some mice. We had initially used another firm that was recommended to us, specializing in trash and junk removal. After they removed some items, they found they were unwilling/unable to complete the job in this hoarding situation. My wife did some research and located Bio-One, a locally owned firm in DC that specializes in hoarding cleanout. We spoke with Tony Holloman, a co-owner at Bio-One DC who conducted a review of the property and recommended what we needed to do. Tony is knowledgeable, very easy to deal with, respectful and understanding with the mental issues driving people to hoarding. We hired Tony and his firm right away and they were able conduct the clean-out and clean-up almost immediately upon our schedule. Tony and his crew and Bio-One clearly are experts in their field, were able to completely clean out, disinfect and fumigate the entire residence and stayed until the job was completed. The work was amazing and the entire house was sparkling clean! The work was professionally conducted, Tony and his team of experts were respectful of the residents and very easy to work with. The results were beyond our expectation – and all done at a fair, reasonable price. We would without hesitation recommend Bio-One to anyone needing extreme cleanup services in the DC and surrounding area. Claire & Jim V.

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.

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 had an urgent need of clean up due to the death of a relative in a hoarding situation. I pray that others never need such a service, but if they do, we highly recommend BioOne. The team was responsive, professional, kind and non-judgmental. Their work was top notch.

    The team, with Jermaine as our point of contact, was able to help our building with a sensitive and often surprising situation. They rolled with the changes that came up and delivered professional and attentive service, keeping us up to date on the day to day operations and being willing to work through tricky scenarios. Jermaine was quick to pick up the phone and addresses everything with courtesy and patience. Thank you!

    Bio-One did an excellent job cleaning up my in-laws apartment after a death. They are very Nic people who helped the family at a difficult time when they didn't know where to turn. The in-laws had been hoarding and hiding it from us - we couldn't even move in the unit. Bio-One cleaned out all the trash and disinfected so that we could have an estate sale for the rest. The customer should be sure to take before and after photos of the affected areas if you plan to file an insurance claim as your insurance company will want a full explanation of what was done.

    Jermaine, Rivas, and Quinn did an amazing job clearing away the previous owner’s mess and making everything sanitary so I can move into my new home. Thanks to their expertise, hard work, and genuine care, I went from heartbroken on the day I got the keys to joyful a few hours after this Bio One team arrived.
