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!

Amazing Service! When I simply didn't know where to turn when dealing with a situation in my elderly mother's home, Tom was there! I can't say enough about his professionalism, ability to problem solve and delivery of service. As well, he was able to promptly connect me to other needed services through his networking. I will call Tom again in a heart beat!

When I called they gave a prompt response and set up an appointment for 2 days away and that was excellent. We settled on a date for the service to begin and they were prompt and on time. They're demeanor was excellent and I enjoyed the manner in which they performed their services. They were completely professional and respected my possessions and myself. If asked I would recommend them to anyone that required this kind of service.

I had to clean out my father's house and I don't know how I would have gotten through it without Tom and his fabulous crew. Tom was very patient and sensitive to the situation. He is trustworthy, dependable and an all-around good guy. I highly recommend Tom and Bio-One.

Horrible reason for needing them, wonderful experience working with them. Fast, efficient, pleasant, and involved - nothing got done without my say-so, which was important. Highly recommended.

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
