Bio-One DC is a very professional company with a speedy response and cleaning the unknown. They completed this job in 60 minutes. I will be referring them to others and using their services as needed. I'm a customer for life. I've also attached some before and after pictures.Thank you Bio-One 🙂 😊

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.

The Bio-ONE DC team was GREAT at helping me clean out my mother's home. The level of patience, professionalism, sincerity, transparency and encouragement displayed by each team member was unmatched! My mother's home looks like a night and day transformation! I would highly suggest Bio-One DC for any biohazard remedy job. 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.

The best service. Called to get an estimate they came right away and the job was done within minutes. I would definitely recommend them and will be using them in the future.

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.

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.

Mr.Holloman and his team were a pleasure to work with. Mr. Holloman was very responsive to my needs and flexible in terms of coordination. He and his team arrived on time and were very courteous and professional. His team provided photos and clearly explained the work performed. Totally great to work with.

Bio-One exceeded my expectations. I’m a property manager and needed to have a luxury condo sanitized 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!!

Bio-One DC has helped out another one of my clients once again. They have become a one-stop shop for all types of hazardous waste. They are extremely meticulous and very efficient. We will continue to utilize their services for the foreseeable future. Great job Bio-One DC!

These guys could not be more professional. They came and surveyed our area that needed cleaning, which was in atrocious shape and smelled awful. Within a few hours we had an estimate and by the next day they cleared our whole basement room. The space is so clean you almost can't recognize it, they took all the junk with them and disinfected the area. AMAZING SERVICE

Tony came out on a hot summer day and did a great job cleaning out a deer mouse infestation in my car. Got everything vaccuumed up, santizied, and fogged clean, all for a flat rate quote. Pleasant dude and nice service all around, would recommend.

The Bio-One team did an amazing job cleaning up a hoarding job for me. Within 24 hours of calling they were at the door ready to go. Prices are fair and customer service is beyond top notch. I wouldn’t use anyone else ever again for a cleanup job big or small.

Finally got rid of the cat urine smell after we tried several different things, so happy we don't have to deal with it anymore. Thank you bio-one!

I was amazed how quickly I got a response from Bio One DC. I spoke directly with one of the owners - Tony Holloman. He was quick to understand my situation and that I needed a prompt resolution. Tony's professionalism and knowledge on how to help me was impressive. Thank you Tony!

This company is very thorough and professional. I was amazed at how quickly they were able to give me a reasonable quote and complete the job. I am very pleased and highly recommended them if you are looking for superior work. Trust me they will not disappoint.

Bio-One were conscientiousl and caring. They quoted a price and completed the clean up in a timely way.

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.

I am very pleased with the service I received from Bio one.

Tony, the owner is easy to work with, explains everything in detail and genuinely cares about you and the project at hand !

This company is prompt and professional! Very satisfied with their service.

Quick fast great experience would definitely recommend them to anybody

Fast and prompt service! Great job Tony!!

Great service! Reliable, fast, efficient and such high quality! Able to book quickly which was great with our situation. Will definitely use again if needed.

Tony and Lawrence were fantastic! Would recommend to anyone experiencing pest issues for quick, high quality removal/disinfecting services.

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!

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.

A week ago, I had an emergency need for a biohazard service and a short time frame of a few hours to finish it. Bio-One DC made immediate arrangements, completed the job swiftly and perfectly, and sent a specialist who was excellent and kind. If I could give more than 5 stars, I would!!

The team was on time, smart, caring, compassionate, efficient, experts at cleaning and disinfecting everything. I had become a hoarder and three months severe back pain prevented me from keeping my place up. It was awful but I felt no shame with the way they handled things. They restored my apartment to being spotless and clean for a healthy living environment as I recover from my spinal fusion surgery. They even found my missing Apple Pencil. I have a new life thanks to them. I cannot recommend them more.

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.

Bio-One! Outstanding service! Left an email at 1am. Tony called at 9am and within a couple hours Lawrence was at my door helping me with all my home needs. What an incredibly efficient business! Everything was handled seamlessly from the initial appt request to outperforming the work my basement required. This company gets an A++++. Tony and Lawrence thank you very much! Very happy with the service.

Bio One DC is THE ONLY biohazard cleanup company I will use for the rest of my career. I manage a condominium and needed biohazard cleanup in three of the units within the building. Tony answered the call immediately, answered all my questions, turned around the estimate in less than 24 hours, and finished the cleaning within 48 hours of the initial call. Jermaine, one of the crew leaders was so nice, pleasant, respectful, and DID AN AMAZING JOB. I will only be calling Bio One DC. I can’t express how satisfied I am with the job. Thank you all so much!!!

Very professional and did an amazing job restoring my floors

Bio-One was wonderful! From Tony answering the phone after 6 PM on a Friday night, to then calling me 45 minutes later to let me know I had an appointment at 10 AM the next day. I truly appreciate his customer service, friendliness, and willingness to help me out in a time of need! Both Jermaine and Dewayne were fabulous! They arrived earlier then the appointment time and walked me through the whole process. They insured me that all of the chemicals and processes they would use were not only safe for humans but for pets. I truly appreciate their timeliness to this matter. I highly recommend and trust the services of Bio-One and would use them again in a heartbeat for any hazardous related issues!

I am giving them 5 stars because a higher rating is not available. They were very quick in their response. It took a crew of 4, Lawrence, Jermain, Wayne and Duane 7 hours to clean a very contaminated and toxic apartment. All of these men were very compassionate in a difficult situation. They listened and offered good advice when I had to make difficult decisions while clearing out a loved one's apartment. Their high standards are not just my opinion. The maintenance manager of this very large apartment building said they use three companies who are very good at what they do, but the crew at Bio-one exceeded the work of them all. Thanks Bio-One!

I contacted Bio one DC to come clean my elderly father’s house due to an infestation of mice. I first met with Tony. He is very personable and professional. Today 5/12/22, Lawrence & Jermain came to do the job. They arrived at the designated time. They were fantastic! Very professional. They did an absolutely phenomenal job. They even did the dishes. They cleaned and moved furniture. I am very satisfied and thrilled that they came and took care of the house. I absolutely recommend Bio One DC.

Jermaine was great! Arrived right on time and their work was incredible. Absolutely recommend Bio ONE

Appt was made quickly by Tony. The job, itself took no more than a couple of hours (morning appt) ending around noon. Jeremy did a fantastic thorough job. The job was not nearly challenging as I thought. Thanks again Bio-One. You’re the one to call!

Bio-One DC was very responsive to my request and questions. They not only confirmed they could handle removing all the empty boxes and other things that had piled up in an apartment during the pandemic, but could do some deep cleaning too. They offered a work date for the next day, but since it was during the weekend and was sooner than I could accommodate, they schedule it when it was convenient for me. There was excellent communication before and during the work. Jermaine, Larnell, and River were very kind about the situation and very helpful in getting the job done quickly. Thank you. If you are in DC area, especially if you need to schedule something quickly, Bio-One is recommended.

This company specializes in hazardous waste clean up provides great service 24 hours a day 365 days a year. They are very compassionate about the needs of their customers and remains flexible to ensure the quality of work is a pure reflection of their core values. They provided me with a quote and an A1 team less 48 hours to assist me with damage that would have cost me thousands of dollars. There is not a job too big or too messy for the Bio-One team. I highly recommend this company to everyone in the DC and Maryland area.

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.
