Gross Filth Cleaning

Gross filth can be difficult and dangerous to clean, as it often contains biohazardous waste. Bio-One of DC has the training to remain safe and remove it all. Don’t risk lingering diseases. Let the professionals handle it.

You called the right 
ones for the job.

Gross filth often entails bacteria, viruses, and mold. These are harmful biohazards that must be properly sanitized and decontaminated. If left untreated, each will grow and become progressively more dangerous. At Bio-One, we have professionally trained cleaning technicians that remediate these kinds of problems for a living.

Bacteria & Viruses

Exposure to bacteria isn’t necessarily bad. Everything is covered in bacteria, it’s a part of our lives. However, certain forms and viruses can be harmful (Covid-19).

In light of this, we have gathered all necessary equipment and knowledge to sanitize and disinfect. We can decontaminate whatever gross filth needs cleaning.

Mold

Mold doesn’t require much to colonize. 24 hours and some excess moisture typically does the trick. Whether we need to decontaminate the surface or remove pieces entirely, the job will get finished.

Each site varies in severity of mold and gross filth. The quicker you call, the less damage there will be. We are available 24/7 to give you the best chance of stopping the spread.

If it escalates and something must be torn out, we will reconstruct it. We want to leave you with a comfortable, safe environment. Not a bunch of holes in the wall.

Community Outreach

At Bio-One of DC, we work closely with the Washington, DC community to ensure a safe and clean environment. We strive to make a difference here.

For many years now, we’ve been proud to partner with local authorities, charities and other groups. We offer them the most up to date cleaning methods and techniques to keep our area safe. As the owner, I, Antoine and Torrie Holloman, can promise that you’ll receive the best help available from the professionals at Bio-One of DC.

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.

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 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.

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.

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.

I contacted Bio-One DC on a Thursday to provide an assessment of a barn on one of the Park locations for the removal of Raccoon Feces. Tony immediately responded to the site within 30 minutes and provided a quote for services. Later that afternoon, I was sent an estimated proposal for Remediation of the site the next day. The team arrived on a Friday and immediately went to work. The location was engulfed with Raccoon feces on the stairs and both levels of the barn. Upon completion, the staff sent me pictures bolstering how impressed they were with the clean-up and how good it now smells. I appreciate the professionalism of the Bio-One DC team and efficiency of the service.
