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 and his team were great!

First time home owners here. We decided to take the safe route before moving into the property and get the house sanitize due to covid 19. I did a Google search for the top best covid cleaning companies and found Bio-One Chester County. I was very nervous but after speaking with Tom, he put a sense of calmness to the conversation which made everything go smoothly. This is my first experience with Bio-One and I can not say enough great things about them. Prompt, nice, hard workers and very detailed! You can't go wrong picking Tom and his crew for your cleaning service. I would recommend their service to everyone. I will be sharing there information on all our social media.. A BIG THANK YOU to you guys for all you do during this pandemic and coming to help us out today. We appreciate your service. God bless and Please continue to be Safe out ther 🙏♥️

Fast, friendly and efficient. From the first call till completed work the customer service was above and beyond. Plus Comet loved Tiffany (and my dog is an excellent judge of character.)

Tom's service was invaluable to me during a sensitive situation. He was personable, efficient, flexible, professional and his advice was appreciated. Tom and his team were reliable, thorough, and overall did an outstanding job with the decluttering and cleanout of a challenging residence. I would absolutely recommend Tom and his Bio-One company.

Tom and team did an amazing job and showed nothing but respect in what was a difficult situation. His responsiveness, professionalism and honesty made this a very easy process. My family would highly recommend!!!

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.

Big shout to Tom Gervasio for an outstading job that he performed on my vehicle. He was efficient , professioal and courteous.Thankyou for helping me through a difficult situation. Thanks again . Dawn Miller.

Handles sensitive situations with professionalism, patience, and kindness. Would recommend highly.

AMAZING service. Tom, Tiffany, and Eric were absolutely phenomenal at getting rid of decades old pet urine smell from our basement. They were professional, showed up on time, and took care of this issue with the best possible outcome, keeping us updated on the progress throughout. Tom explained every step as they were doing it and gave realistic expectations. I went to check out the smell today, one day after they finished treating and sealing my basement, and there is ZERO pet urine smell! Tom was fantastic to work with, always responding promptly, and gave honest and helpful opinions and referrals for other work to be done. While I hope not to need their services again, they would be the FIRST people I would call should the need arise. HIGHLY HIGHLY HIGHLY recommend!
