			The owners of Bio-One Denver were available, communicative, and helpful right off the bat. They took the time to walk me through their process of cleaning my vehicle, billing through insurance, etc. This a quality company with great people running it. I can't say enough. Had a really positive experience with them.		
Sarah Kinn

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

Elizabeth Wood, Denver, 7/2/2025

Bio-One helped us tremendously with a tough situation. From the initial phone call with Gregg, to meeting with Kevin and Elvis, everyone was helpful and caring. It's amazing to me how much they were able to do to help us - from removing carpeting, treating the home with the right chemicals, dealing with the insurance company and assisting in clearing contents. The entire team really know what they're doing and are very competent and efficient. I highly recommend them and can vouch for their integrity.

Kevin Forsyth, Denver, 2/6/2025

Cleaned up an emergency situation as if nothing ever happened.

Carol Peeples, Denver, 2/1/2025

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.

Regina Cunningham, Denver, 1/17/2025

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

Jacob Stark, Denver, 1/10/2025

Bio-One helped my clients on short notice right before Christmas. They were very helpful, quick to act, and did the job right so my clients could close on their sale and move on. I recommend them for anyone needing a quick, but thorough clean up.

wanda Gurule, Denver, 1/7/2025

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.

FREQUENTLY ASKED QUESTIONS

What is Hoarding?

Hoarding is a behavioral pattern characterized by the excessive acquisition of and inability to discard large quantities of objects that cover the living areas of a home and cause significant distress or impairment.

Compulsive hoarding behavior has been associated with health risks, economic burdens, and adverse effects on personal relationships. When clinically significant enough to impair functioning, hoarding can prevent typical uses of space so as to limit basic daily activities like moving through the home, eating, and sleeping. It can also put people at risk due to increased risks of injury, fire, and disease.

Why Hire Bio-One of Denver To Cleanup Your Hoarding Residence?

Bio-One of Denver prioritize concern for the well being of our customers and their families, always following our slogan, “Help First, Business Second.” Bio-One of Denver soundly reject the business-first mindset of other companies who see people and their families asking for help as vulnerable and exploit the economic opportunity. Our primary goal is to help people improve their lives and begin the process of moving forward.

What Makes Bio-One of Denver Different From Other Hoarding Cleanup Companies?

Bio-One of Denver sets itself apart from other hoarding cleanup companies in four distinct ways:

Bio-One of Denver come to give on-site estimates, never blind, inflated estimates over the phone. This allows us to give an accurate estimate and scope of work.

Bio-One of Denver do not give bait & switch quotes. Unlike other companies that lowball their estimates and then ratchet the price up as the job progresses, our experience and expertise allows us to give accurate estimates that reflect what the job will cost.

Bio-One of Denver are truly a local company, the owners and employees all call the Denver area home, too. Other companies take your call from outside our community, and then subcontract your job out to some workers who are neither hoarding specialists nor trained professionals. Many times the contracting company does not even know the subs they have hired.

Bio-One of Denver respond to a hoarding cleanup request immediately because we are locally based. We're not heading into the area, we're already here.

Does Bio-One of Denver Share Information About Or Notify Any Other Entity Regarding A Hoarding Matter?

Yes. Bio-One of Denver offers a regularly-scheduled maintenance program where Bio-One of Denver return to the residence or property after the initial cleanup and perform follow up services to ensure that it remains in the state it was when we completed the job.

Does Bio-One of Denver Offer Any Maintenance Or Follow Up Service After The Initial Hoarding Cleanup?

Do I Have To Get A Maid Service After You Are Done To Clean The Property?

Yes. While the original hoarding cleanup will result in the removal of all necessary/requested items, the hoarding residence will still be in need of a thorough and detailed cleaning, due to the effects caused by the original hoarding situation. Bio-One of Denver offers a detailed cleaning program to anyone who's interested.

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!
