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

I am so appreciative of Bill, Mike, and Joe. They did a fantastic job on clearing out a house for one of my family members. They were very compassionate about the situation from the first time talking to Bill on the phone all the way through the last day of the clear-out. Thank you Bio-One!!

Bill and his team were great! Handled the hoarder situation professionally and respectfully. Thanks so much!

Even more than the quality cleanup work they do, there's significant compassion and understanding that comes first. From the first phone call to getting a quote and service the next day, they were great, got the job done quickly, for a great price, and most of all, with kindness. Whatever kind of cleanup job you may need help with, whether you think it's huge or small and overwhelming either way, it's absolutely worth calling and asking for help!

Highly recommend working with this company. Very honest and great people.

I've got to be honest, I never wanted to have to work with a company who does what these guys do. I don't think anyone does, but I'm so glad it was them. Discretion, transparency, professionalism... These guys nailed it. I'm one of the biggest skeptics of people these days for good reason, there are a lot of people out to make a dollar without regard for who they crush on the way and these guys are NOT THOSE GUYS. I know I'll need to use their skills again in a few years and they'll be the first ones I call. They'll be the only ones I call. 5 stars all day every day. Thank you guys!

Bill and the crew from Bio-One Chicago are incredible. They are truly compassionate people and they perform their work with the utmost care, respect, and professionalism. In addition, they're extremely responsive, quick, and cost-effective. It's rare to come across a company - and a group of people - like Bill and his team at Bio-One.

As usual , Service is great

I was very happy with the work done in my grandmother's building. The men that came to work were a blessing to me and my family. Very satisfied and would use there services again. Luis Gonzalez

Bill and Mike have been a true help to us during a time that has been filled with shock, confusion and grief. They are communicative and compassionate and we are so lucky to have them helping us in our time of need. The work they do is hard and they do it with grace, compassion and respect. Highly recommend if you ever are in need of this kind of service. Thank you so much Bio-One Chicago!

I have managed building for a long time and have been fortunate to have never needed an extreme cleaning company before. That changed a week ago when we opened a wall to track down a leak in the basement and found a former bathroom that had a 5 foot tall pile of construction debris that filled the room. When we shifted the debris out of the building, we uncovered a drain. In the time it took to get a plumber in to plug the drain, we had a few rats enter the building. Exterminators made quick work of them. But they left their mark in the exposed room. Bill was great in getting Amanda out immediately to the site for an estimate. Amanda was very pleasant to work with and did a fantastic job getting that dingy room in the walls clean and sanitized. I greatly appreciate Bio-One and all their help and will be adding them to my service contacts list.
