WOW! Dan, Oscar and Toby showed up at my house 2 hours after my phone call t... o Ryan. I was impressed already. These extremely polite and friendly men showed up and within 2 hours had all the carpet torn out, the wall board cut away and the sewage backup cleaned up, cleared out, deodorized and sanitized. They explained everything they did as they were doing it in the most professional, friendly and polite way imaginable. They were constantly concerned about my safety and well-being. They treated me like family! I've never had better service in my life and I thank each and every one of you for helping me so quickly and so thoroughly. I am singing your praises to anyone who will listen 🤩 Thank you, thank you, thank you. You took a horrible situation (sewage pouring through a wall into my living room carpet)and made it better. I give you 10 stars‼️💐   Read more >

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.   Read more >

"Tony, you did great setting this up on a near-emergency basis, and the job ... was successfully completed in one day as promised. Don't know if you know, but the crew didn't finish until 9:20 pm--a very, very long day. I want to take this moment to sing praises of Revis and his crew. Revis was an absolute monster to get the job done to my satisfaction, asking me over and over in the evening if the cleanup met my expectations. It did, and then some. Also, he was instrumental in helping me find various objects and boxes buried in the pile of debris in the rooms, setting them aside for me to examine. I asked him to do this, not expecting much success, but he was very thorough in setting things aside for me. Can't say enough good things about him, and his crew!"   Read more >

    I want to thank Jermaine and his crew for doing a superb and wonderful job of helping us at a very difficult time for our family. We receive... d shocking and tragic news and Bio-One was recommended to help us with circumstances that we now faced. We are so thankful to have called a company that is very professional and showed a warmth that we really needed. We also have to mention of how your Crew showed such dedication when we mentioned that when we would be in the VA area to clean out this apartment, we had small window of time to do this. Immediately your Crew helped us with such dedication and patience which gave us such relief and we were even more grateful and glad we contacted Bio-One. I would highly recommend this company to any one who ask me about your establishment.  Read more >
