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.

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.

Crew did a great job cleaning my basement after a sewage back up… And Bill made the estimate process super easy too. Will definitely use again if needed in the future!!!!

If you find yourself in a stressful situation where you're having to find a clean up company to handle a clean up job that would be hazardous to take care of yourself, I highly recommend this company. I have used Bio-One one 3 separate occasions and they've consistently provided amazing customer service every time along with trying their best to squeeze us in as best they could with their already crazy schedule. I used their disinfectant services but here's Keywords for other services they provide: crime scene clean up, biohazard clean up, covid fogging, covid clean up, disinfecting, hoarder clean up
