Stephie Berman, Chester County, 05/05/2021
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!

I needed a rapid turn-around on an apartment clean up for my Senior loved one who had an unfortunate fall into some self neglect and squalor. I conducted an internet search, and was able to reach Tom. I spoke with him in depth avout my family's needs. He was compassionate, and efficient. On the day of clean-up he and the crew were on time and eager to get to the job. Tom was honest and realistic about the job. The team were extremely patient and affectionate to the pets that were caught in the clean-up. Tom kept in touch throughout the clean-up until the end. I would refer them to anyone who finds themselves in this type of crisis needing a company that is professional, compassionate, trustworthy and efficient.

I would recommend Bio-One. Tom was professional in showing up when planned and keeping me informed of the progress cleaning out a hoarding situation in a house I was selling as an executor. Given the difficult situation, his crew worked quickly and in the end left the house clean.

Tom and his team promptly responded to my need for a home cleaning after a COVID quarantine. They were extremely accommodating despite my last-minute request. They made it to my house within a day of contacting them and kept me updated the entire time. Once at my house, they worked efficiently and even offered to extend their services to disinfect my car. They went above and beyond for me and also happen to be some of the friendliest people I've come across. I would highly recommend Tom and Bio-One!

First time home owners here. We decided to take the safe route before moving into the property and get the house disinfect 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 🙏♥️
