We're ready to serve you!

These guys were awesome! Very professional and in and out in just a few hours! I highly recommend them for any service you may need!

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.

I saw them cleaning up the trail near my house due to homeless encampments. Really appreciate what they do.

We are extremely grateful to have found Bio-One of Denver to do this house cleanout and deep clean. It wouldn't have been able to be done without them. Wonderful people!

We are renting a house that was previously occupied by hoarders, so I contacted Gregg and his team at Bio-One to come out and look at the property. To my delight and surprise, Gregg was open and honest and let us know that his services were probably not going to be the most cost efficient for our needs - he recommended another cleaner and was honest about saving us hundreds, if not thousands, of dollars. While I didn't use Bio-One's services, I would recommend them 100 times over for their excellent customer service and best business practices!

We had Justin, Joel and Sarah come out to help us get three sheds with serious mouse infestations all cleaned out. They did an excellent job in a timely manner and were tremendously friendly and professional. Would definitely hire them again!

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.

Most helpful and thoughtful company! I called to ask for an estimate on getting a meth test done on my recovered stolen vehicle and the owners were so knowledgeable and kind! They gave me advice on the steps to take before getting the test done as to not waste my time or money on the testing. They were so compassionate and caring! HIGHLY RECOMMEND THIS COMPANY! :)

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 ❤️

Gregg and team were amazing to work with when dealing with my fiberglass problem. I called on Wednesday and they had someone out that afternoon for a quote. They came that Friday and it was clean by the afternoon. I really appreciated the fast response time and communication from Gregg. I highly recommend this company! Thank you.
