Animal Hoarding Cleanup

Animal hoarding can be hazardous to not only the owners, but the animals as well. This practice leads to a severe drought of sanitation, food, water, medical care, and space. Conditions can become severe and should be treated by professionals.

You called the right 
ones for the job.

Nobody wins when it comes to animal hoarding. It can be a very dangerous situation for both the property owner and the animals themselves.

At Bio-One Dc, the safety risks are understood. We aim to provide a healthy and livable environment for anybody who’s been involved. 

Owner Risk

In our experience, the owners are put at great risk by hoarding animals. The danger lies in the fact that they can’t see that. Once the hoarding has started, animals are continually welcomed with no end in sight. The owner tends to neglect their own needs and provide for the animals first. 

Hygiene, food and water are the first to be affected by this practice. Animal waste gets airborne and can directly impact any food and water sources. This animal waste could be coming from:

  • rats
  • dogs
  • cats

Typically, their waste carries bacteria and parasites which are linked to human disease. Thus, tainting food and water available to the owner without their knowledge. 

Animal Risk

Much like owners, the animals in these situations tend to suffer from poor nutrition. It’s not uncommon to die from starvation.

These animals get into fights over territory and are frequently injured. Untreated maladies and mental distress from constantly fighting doesn’t end well. It’s not a good environment for them to be in. 

Cleaning Process

We work closely with the owner to ensure these risks are understood. Once that step has been reached, we continue with our cleaning process:

  1. Any items that have been highly contaminated by animal waste will be removed
  2. Cross-contamination safety protocols will be in place as a precautionary measure
  3. Once removed, the items will be disposed of responsibly

Our professional cleaning crews will be able to transform the impacted area into an unrecognizable utopia. Ultimately, we want to leave the home as good as new. Your comfort and safety is our top priority. 

Community Outreach

At Bio-One Dc, we work closely with the Washington, D.C. 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, Tony Holloman and Jeffrey Cheeseboro, can promise that you’ll receive the best help available from the professionals at Bio-One Dc.

I called Bio-One spoke with Tiny regarding a dear friend's residence without hesitation he explained his company process and said not to worry they could make a difference. I had to write an endorsement for the work this team of men have done; to endure such an undertaking with compassion and encouragement all while diligently purging three levels within the home. Afterwards coming back and sanitizing each area. Not once did I see a look of disgust. Total professionalism exhibited. Tony gave recommendations to continue maintaining a more healthy living environment. If you know of someone in need of this type of service be a friend provide the support and call Bio-One (Tony) will provide courteous professional service. On behalf of my dear friend Thank you so much. Continue doing exceedingly bless work. Ms.G & Robert

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.

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.

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.

BioOne came out quickly and did an excellent job cleaning a bedroom of rodent droppings. Jermaine was so professional. Cleaning was done quickly and very throughly. And he used professional-grade fogger at end too. Now it smells so fresh. I’m a highly satisfied customer. And so relieved that it’s safe to use that room again. Thanks BioOne and our thanks to Tony and Jermaine!!

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.

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!

Professionalism from start to finish. Let’s start with the fact, they answered the phone promptly and politely on a Sunday afternoon. Within 15 minutes of sending photos of the affected area a technician was dispatched to my location and arrived within the hour. WOW! As you can see from the photo, the affected area was treated with detail and care. 10/10 would recommend!

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.

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.

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.

We recently needed to clear and clean a condo that had been subjected to a couple of decades' worth of clutter and neglect. In order to accommodate the occupant, we needed to be able to break the task down into two or more sessions rather than address it all at once. After vetting multiple companies we hired BioOne. Tony, the owner, worked with us on a plan and estimate that allowed us to efficiently tackle the worst issues in two full days. The crew--Chad, Jermaine, Quinn, and Mason--worked hard and accomplished a great deal in terms of removal, grouping remaining items, and initial cleaning. When we mentioned to Tony that some of the planned deep cleaning had not been completed due to time constraints, he arranged to send a cleaning crew out on Day 3. Shannon and LaKeisha did excellent work and left the place in a condition that exceeded our expectations. We're very happy with the services we received from BioOne and felt they were professional, responsive, efficient, and frankly delivered a better value than other companies we priced for the job. We would recommend them to anyone in the DMV who needs to address a severely cluttered property.

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.

I am in awe of the team and really appreciate all they did to help me during the process. This team is EXCEPTIONAL!

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!!!

They did a great job! They gave me fast service and arrived on time, and were very compassionate about what for me was an emotional issue. I needed a cleaning after my cat brought in a baby rat that took me about 6 weeks to get rid of. It had made a stinking mess in my kitchen in in accessible areas I couldn't clean properly, and I felt I couldn't sanitize any part of my kitchen properly or get out the stench using normal products and techniques. They were able to make my kitchen clean and safe, and get out about 90% of the stench, which has continued to fade since then, and may be gone now. I am so grateful.

BioOne service did an awesome job. In the middle of my critical crisis. I had to make a call to a crime cleaner service. BioOne was one of the top three people to contact. Once I made the called. I explained to him what happen. Tony was extremely professional, kind and courteous. I had to call him a few times. Not once did he get irritated with me. Tony explained the process step by step which help me understand more of what was about to take place. A few hours later he showed up with his technician. They both did an excellent job. I highly recommend BioOne services for all your professional needs.

The team at Bio-One is top-notch. I closed on a property and needed to have to have it cleared before I could start renovations. I called Bio-One and specified what I needed and told them of my timeline—I needed to get my team in the house fast. I’m hey explained their process and was able to accommodate my short timeline. The house looked so different with all the filth the removed. I was surprised after the work was completed because I was able to save. The flooring in two rooms. I will definitely use your service again.

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.

I can’t begin to express my gratitude to Tony and the Bio-One DC team. I came to DC to begin the process of handling my late Uncle’s estate and belongings. I was more than a little overwhelmed at the condition of his apartment and the sheer volume of “stuff” it held. I called Tony on Friday night and he had a crew meet me Saturday morning. Lawrence and Jermaine were incredible! They were friendly, compassionate and more than prepared to handle the task at hand. I’m still amazed at the difference after they spent the better part of their Saturday (6 hours) tackling the chaos. They were incredibly efficient and did an amazing job. I highly recommend Tony and team.
