Tom and his group made what was a really difficult situation manageable. They were respectful, fast, kind and did an amazing job. Anyone dealing with a hoarding/cleanout situation will not find a more compassionate or competent group of people. And they came in under estimate. Can't recommend highly enough.
R. B. Weiss
Bio-One Chester County is the best company to hire for cleaning up messes that are beyond your capability to handle. Tom estimated the cost, materials and number of days to complete the project. Despite the need to scale the job up during execution, the job was completed on time and on budget. Tom and his crew are great! They are punctual, professional, talented, experienced, humorous, and honest. When unanticipated problems arose during execution, Tom called immediately to discuss resolution options and provided guidance to lead me gently to what I believe to be the best option. You can't go wrong by hiring Bio-One Chester County

Tom was quick to respond and give me an estimate for cleaning out my cousin's home. Me and my cousin, who is ill, differed on what to toss/what to keep. Tom was great at stepping back while my cousin and I "negotiated", and stepping in when we needed clarification. He's understanding, experienced, knowledgeable. He and his crew were quick, personable and flexible!!!! If you're like me --embarrased about having someone see a "beyond messy" house - don't worry. Tom knows instinctively how to put people at ease. So quit procrastinating and give him a call!

    We weren’t happy with the reason we needed his services (raccoon feces) , but Tom made things so much better. He answered my call promptly and was so helpful. He came at the appointed time and was incredibly efficient. There were a few hoops for him to jump through regarding our property, but he took it in stride and came out victorious! I highly recommend him! Totally thorough, accommodating and friendly.
