Denver Deep Cleaning Service

You shouldn’t be embarrassed by asking for help. This is what we do. Whether it’s a few rooms or the whole house, Bio-One of Denver will clean without passing judgement.

You called the right 
ones for the job.

When you declutter and deep clean with us, you will be left with a house that's unrecognizable from when we started. There’s no true limit to what we can do. After 20+ years of experience, there’s yet to be a job we couldn't handle. 

You may think many items in your house are a lost cause, too dirty and nonfunctional to save. However, using proper techniques we commonly change that narrative.

Nothing is too dirty for us to salvage. All of our cleaning technicians understand this. Each one has been trained on the proper procedures. You may be surprised at what we can do. 

Declutter

We’re very compassionate and understanding of our clients during this process. Clutter isn’t garbage. We get that. We simply organize what’s available, and dispose of unwanted items to clear room for living. Your property will always be treated with respect by our crews. 

Deep Clean

Deep cleaning is intended to be a very thorough process. Common areas that we clean during this time are:

  • Underneath heavy appliances (fridge, washer, dryer)
  • Inside typical appliances (oven, microwave)
  • Walls, ceilings and floors

If you’ve never thought about cleaning there, it will be on the list. By the time we’re done, there will be no room left unturned. Whatever you need cleaned, we will do it. This is a service for you, and we haven’t forgotten that. 

Community Outreach

At Bio-One of Denver, we work closely with the Littleton, CO community to ensure a safe and clean environment. We strive to make a difference here.

For many years now, we’ve been proud to partner with local authorities, charities and other groups. We offer them the most up to date cleaning methods and techniques to keep our area safe. As the owner, I, Gregg and Cheryl Chiasson, can promise that you’ll receive the best help available from the professionals at Bio-One of Denver.

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 ❤️

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.

Gregg and the cleanup team assigned were kind, considerate, and efficient. A relative had died and had not been discovered for several days. We appreciated the timely response and efficient removal of contaminated materials. Their approach made a terrible situation as quick and simple as possible.

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!

Bio-One was an incredible company that I found under extremely unfortunate circumstances. They cleaned up after a very traumatic unattended d3ath and addressed it with professionalism and compassion, which was greatly needed after losing a parent. While I hope I never HAVE to use them again, I absolutely would in a heartbeat.

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.
