Thank you for trusting us.
We're ready to serve you!

We live in rural Northern California and during a home inspection for the sale of our house our crawlspace had been a haven for rodents. I called Bio One and Seth came out immediately and corrected our rodent dropping issue. He was so kind and considerate at a time that is very stressful for me. Thank you so much and the world needs more customer service like your company!

Bio One did a complete biohazard cleanup of my apartment after my recent hospitalization for a highly contagious bacteria. From my first consult call, Seth, the owner, patiently answered all of my questions and addressed my concerns regarding the nature of what I was dealing with and what it would take to rectify. (I could have gotten reinfected as the spores remain for up to 5 months!) Sean is very professional and knowledgeable; and as a bonus he is a great person with maybe an untapped talent in comedy. I highly recommend Seth and Bio One for an excellent biohazard cleanup that will fit your specific circumstances.

Exceptional Service with Compassion – Bio One Went Above and Beyond During one of the most difficult times for our family, Bio One stepped in with professionalism, empathy, and unwavering support. From the very first interaction, Seth was incredibly compassionate and understanding, guiding us through the process with care and sensitivity. He took the time to explain everything thoroughly, ensuring we felt supported every step of the way. His team, Zac and Rob, were equally outstanding—kind, respectful, and incredibly detail-oriented in their work. They handled everything with the utmost professionalism, ensuring that the space was restored with dignity and care. It was clear that they weren’t just doing a job; they genuinely cared about helping our family through this challenging time. The level of dedication, discretion, and efficiency Bio One provided was beyond what we could have hoped for. Their kindness and expertise made an unbearable situation just a little bit easier to navigate. We are deeply grateful for their service and highly recommend Bio One to anyone in need of compassionate, professional assistance during a difficult time. Thank you, Seth, Zac, Rob, and the entire Bio One team—you made a difference when we needed it the most.

Bio one was a great company to work with! There was unfortunately a pile of human feces near my business entrance this week. They were speedy and reasonably priced compared to other bio hazard clean up companies. Thanks again Seth!

Came to clean out my garage today. Did a fantastic job Sanitizing it to make it look brand new. Definitely would recommend to anyone wanting to clean up a house. Fantastic and quick service. Friendly staff.

"Very friendly and professional crew, with affordable rate. Used their services for cat urine removal and spot fix, with additional carpet lift and inspection for entire house. quick clean up and fast service."

They did a fantastic job!

I can’t say enough good things about Seth Ramey and the crew he sent to help. Seth is a truly kind, honest and caring individual who understood what I needed and helped me achieve my goal. The young men, Angelo and Nilo, were polite, fun to be around, and worked so fast it took my breath away. They took care of all my requests and were always pleasant and helpful. I would recommend Bio-One for any job that they specialize in and gladly use them again. Thanks so much for helping an older person get their home in good order again. They really are true heroes.

Seth was an awesome blessing! He was super helpful and patient with all the planning that went into cleaning my moms house out. His crew was detailed and very easy to work with. Within just a few days of the crew completing the clean out and clean up the house was on the market and sold within days! I would definitely use Bio-One of Sacramento again.

Seth is such an amazing and kind person dealing with unique jobs and issues! Communication was great and he really made the extra effort to fit in my small job. I truly can’t thank him enough and would use him again no hesitation! Highly recommended.
