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

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!

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!

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 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.

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!!

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!!!!

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

Bill Muir and I met a few years ago. I have referred him to many people. Today he is doing work in my house, so grateful to know that the flood damage from the fish tank will be taken care of and my house will be whole once again.

Bio-One's team were an incredible godsend during an extremely difficult and traumatic event. their communication is top notch, and they clearly lay out what they can provide for you or your family. they have a variety of services, but each job is met with genuine care and concern. Bill and his other team members are absolutely Wonderful people, patient and kind and hard working.

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!!
