Becca and Frank were very courteous. They service me needs very promptly and thorough I an pleased with the way they handled a very sensitive situation. They understand what they are dealing with and they explain thing clearly.

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!

I have known the owner, Uduak for over 10years. Her character and work ethic speaks for itself. This is the same standard she applies to her business. She is compassionate, thoughtful, dedicated , and treats people with dignity. I would be confident to use her company Bio-one for any cleaning services.

I was a dunderhead and thew a package of mothballs into the attic to evict squirrels. It evicted the squirrels but came close to evicting me. I needed to have the mothballs removed from my attic or else move to a hotel. Matt Gregg took care of the problem within minutes. He arrived exactly on time, followed the instructions as to how to access my house from the alley, and greeted me with a smiling handshake, which in the era of Covid has become a luxury. The whole process took 30 minutes. Matt showed me the bucket of attic mothballs and answered my prayers, and believe me I was praying. Note to self: NEVER throw mothballs into the attic. Bio-One is a big company that usually does horrible jobs like crime scene cleanup, so I was incredibly lucky they had the time to restore my life in my house. Thank you Matt Gregg, and thank you Bio-One.

Patricia and her crew were amazing. If you are in need of a service like this, could not recommend them enough.

I can't say how much I appreciate the work this team did for me. Life-changing is an understatement. They did an amazing job on what was coincidentally one of the worst days of my life. And they did it with kindness and great care. It was a reset I really needed, and I don't want to think about what that day would have been like without them.

We were very pleased with the work Bio-One did for us. They cleaned out our attic, which had lots of bat-droppings. They carried furniture and boxes down, cleaned out all the droppings, disinfected the space and painted the floor. They were very professional and did a fantastic job. Highly recommended.
