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.

Bio-One Hoarding is ready to assist you.

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.

The team helped my family member tame two years of long-Covid clutter in two days. From our first contact with Gregg to the end of the process, we were treated with dignity and understanding. Our only regret is that we didn't call sooner!

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.

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.
