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

We were absolutely blown away by Gregg and his team—not just by the incredible results, but by the outstanding professionalism and kindness of every single person who showed up. With our move, we’ve had over 10 different vendors in and out, and honestly, every one of them should be taking notes from these guys. The team was respectful, thorough, and went above and beyond to make sure everything was done right. It’s rare to find a company that delivers this level of service, and we couldn’t be more grateful. We will happily refer them to anyone looking for top-notch service. Highly recommend!

My call was returned quickly, Gregg explained how this works, I wasn't real happy with evaluation after Justin returning and telling me it was a 1 on a scale 1-10 but Justin was on time, very professional and communication was excellent. Made sure I was satisfied before leaving. Only wished I would have gotten before and after photos since I'm not one to go into my crawlspace. At this time I am very pleased.

From the get go when Greg came out to look at moms house he was very professional and compassionate. The day the job started everyone in the team worked hard, followed direction, even made time to listen to moms stories which made it easier on her to let things go. Overall the team was amazing and did a wonderful job exceeding all our expectations. Definitely recommend highly.

Cleaned up an emergency situation as if nothing ever happened.

This company is AMAZING!!!! When I had to experience one of the hardest days in my life, Gregg and his team of Jase and Eric were incredible. They came and helped to take care of something that I just couldn’t and they were so comforting. Not only were they kind, gentle, thorough, and helpful, they were also informative and professional. I was met with the utmost empathy and it made the worst day of my life able to be digestible. They hugged me, talked with me, let me get out my feelings and emotions while also keeping me level headed. I have told anyone that will listen I am so glad that I called this company above all the rest. It wasn’t just business to them, it was a compassionate encounter. In addition Gregg and Jase both called to check on me and my wellbeing within the following days and weeks as this was the hardest loss of ever! I couldn’t recommend a better group of people to help get through a horrible time. I appreciate them so much, I wasn’t a customer- I was treated as family. Thank you so much ❤️

BioOne responded quickly to my issues I had at my residence. They were professional, personable, responsive to all my concerns / questions. They completed the task in a timely manner, they cleaned up every day after and made sure we were happy with their quality of work. Thank you again BioOne

Bio-One was there for us with every step of the way during cleanup after the death of a family member. The team was responsive, empathetic, organized, efficient, helpful and thorough. Highly recommended for biohazard remediation, deep cleaning, trash removal and overall helpfulness should you be in a position to need their services.

Thanks for the superior service under such difficult circumstances, Bio-One Denver & Denver Hoarding. Phil and team were professional, discreet and so kind, and did a wonderful job.

They helped me cleanout a hoarding house that I purchased. When I contacted them they were able to start very quickly and had it completely done in 3 days. I really appreciated the quick service.

The company was professional and less expensive than the other ones who provided an estimate. I also found the owner very easy to work with.
