Amazing service and people. Helped us with a tough cleaning job that included blood and did it with compassion and respect for our family. Highly recommend.

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 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.

We moved into a new home and discovered some remnants of mice in our utility room/crawlspace. BioOne came out and did a fantastic clean up job! The peace of mind is priceless. Thank you BioOne for giving me the best peace of mind in our new home!
