Bio-One of DC decontamination and biohazard cleaning services


Washington DCTeargas Cleanup

Teargas residue doesn’t clean itself and takes months to subside if not properly removed. Although rarely fatal, many health risks arise from the residue. Let us clean it for you to avoid further complications.

You called the right 
team for the job.

Teargas is tricky stuff. Unlike other substances, it doesn’t just fade away. It takes months for the effects to subside.

Action must be taken. However, because everything is coated in the residue, cross contamination is likely. Professionals are recommended when dealing with teargas.

Cleaning Technology

Using the newest technology available, we can stay ahead of potential problems caused by this agent. By properly removing any hazardous residue and preventing cross contamination, no harm will be done.

Regardless of a personal or business setting, we are trained and certified for this very scenario. 

Health Risks

Exposure to teargas prompts many health risks. Skin irritation is commonly reported immediately after exposure. The longer the exposure, the more serious the problem:

  • Respiratory issues
  • Motor control loss
  • Heart damage
  • Liver damage

With an agent such as teargas, it’s important to act quickly. We make it our job to eliminate the risk of long-term exposure for you.

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.

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.

Phenomenal Company!!! Prompt. Compassionate. Thorough. Excellent Customer Service. I came into the ownership of a property of such poor condition, reputable cleaning services were turning my case down flat. Then there were the scam artists. Finally there was Tony from BioOne. This gentleman is the real deal. Quality. Integrity. Superb communication skills. BioOne did not just impress me, they impressed the neighbors. Within days of receiving an estimate, Tony and his team were on the property getting the job done. BioOne surpasses any expectations I had, both in quality of work, and in professionalism. Start to finish, Tony gets the job done!!!

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.

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!

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.
