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

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!

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!

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

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!

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

Bill, Mike and Joe are phenomenal men and biohazard cleaners. My husband and I had mice in our house. Usually it's no big deal. We would get 1, put out the glue traps and in a day or 2, it was caught. Never to see another until the next year. In fact, for the last few years, we had zero. Last year was traumatic. We had more than one and they were avoiding the sticky traps. Unlike the other mice, they were way more active. We moved out of our home for awhile. We ended up calling pest control who came out and did a wonderful job. Then I thought we needed the house cleaned and sanitized by professionals. We couldn't do it ourselves as I am immunocompromised and have really bad asthma and my husband couldn't either. I did my internet research and came across Bio One. I spoke to Bill and we spoke as friends. Wasn't expecting that. I had called other companies who never called back or spoke to me like business as usual. Let me point out, I don't mind that. These days customer service is rare. I don't expect chit chat. I don't expect niceties. I do expect you to do your job.Bill sold me when we talked. I believe that he believes in knowing your client, if at all possible. Also, treating you with kindness and dignity. It was Mike who came to my house to look at the "damage" aka mice poop. He thoroughly explained what the process would be, how long, etc. He also answered all my questions. I got an estimate via email of the charges later. Let me say, because of Bill and Mike I went with their service. There is another company that would have charged me less but I feel like they didn't care about my husband and me and my concerns. If they didn't care about that then that attitude would carry to their service. Mike and Joe came to clean and sanitize. It took a few hours, it wasn't all day. (My home is @1000sqft) They had said one, maybe two days. I was shocked. I was more shocked when I went from room to room and saw NO mouse feces and even some of the things I had strewn around my house kinda "organized." They went above and beyond. Mike, Joe and I ended up just talking after and I was relieved. Having pests in your home causes embarrassment. It makes you feel dirty even though it may not be your fault. I did not feel judged or uncomfortable with Mike and Joe. I felt like they were here to help us. As one human would do for another. Go to their website, bioonechicago.com to see all the biohazard services they do and how you can contact them. You will not be disappointed. Bill, Mike and Joe are extraordinary people and will give you extraordinary results. They are also fair about their pricing. The only disappointment I had is that I didn't get to meet Bill. He's a hoot and a half!!

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!

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!!!!

As usual , Service is great

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.
