Jasmine McCalla
We had the absolute best experience with Tom and his team at Bio-One. They were thorough, professional, courteous and very kind - all things that were greatly appreciated and valued given our situation. Would give them more than five stars if I could, highly recommended.
Elizabeth Latino
What an amazing experience. A member of my family has struggled with hoarding disorder for many years. It wasn’t until I came by to visit that I found that it had progressed to the point where her house was extremely dangerous and hardly livable—bags piled to the ceiling in every room, and every desk drawer and cabinet filled to the brim. Some windows were inaccessible and had not been opened in years. I called Bio One to inquire and the owner, Tom, thoroughly answered all my questions and walked me through the process and gave me cost estimates. Over the course of a few days, I watched Tom and his very respectful cleaning team transform her house from a garbage dump into a beautiful home. Bio One literally changed our lives for the better. I highly recommend them. They’re really the absolute best!!

Tom and his crew were very thorough and extremely easy to work with. They did a great job cleaning up my carpets and even went the extra steps to rent a rug doctor before coming to my house to steam clean the carpets after they were done. I would highly recommend this company. JScott
