I can't say enough good things about Bill and his team at Bio-One. Bill was very understanding about a difficult hoarding clean-out at my mother's house in Lake County, IL. The team worked diligently and discovered many valuable items I had no idea existed. They really went the extra mile to review, sort, and clean. Plus, the clean-out was very discreet to avoid any embarrassing conversations with the neighbors. Bill was in regular contact and is such an understanding and kind person. I interviewed numerous companies prior to selecting Bio-One. Bio-One clearly understood the human aspects of an unpleasant situation much more so than the other companies. And, based on the competitor cost estimates I received, I was very pleasantly surprised at the end of the job. Bill's estimate was accurate and ended up being a significantly better value than the next nearest competitor.

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!

As usual , Service is great

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!!!!

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.

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

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!

I would give them 6 stars if I could, but only 5 are allowed! The team of technicians who came to our house were all friendly, understanding and polite. They guarantee their work, and they are true professionals. Thanks guys!

Easy to work with, impeccable work, friendly, and compassionate. They totally transformed and resolved an extremely difficult situation and I am so very grateful. I highly recommend them!
