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 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 disinfecting 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

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!
Sophia Melonē, The Debt Demolisher
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.

    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.
