Pat Atkinson, Chester County, 9/9/2023
"Rarely have I had service in any capacity like the EXCEPTIONAL SERVICE GIVEN by the Entire Team at Bio 1 of Chester County!!! Tom picked up the phone at 9:45 at night after my spending all day with another "" Cash only"" vendor . He spoke in clear Terms about the Bio Hazzard job & the insurance process. He made all this happen in Record time and did all the Insurance paperwork too!! Tom also recommended another vendor for a different service, and they were also stellar!! I JUST HIRED Bio 1 of Chester County AGAIN this week for another clean up, and my neighbor Vicky texted me to remark on what a fast and efficient job they did. I am placing them in my phone for future work, they are worth their weight in PURE GOLD!!! There are NOT alot of people in any line of work that could match Bio 1 of Chester County!!!"

Bio-One helped us clean out a hoarding situation in a rental unit. They were quick to provide a price, very reasonable and were able to clear it out in one day. Would definitely work with them again.

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.
