Bio one Chester county Just recently did a job for me. I had dogs that Peed on a concrete floor in the basement. Several other companies were not able to guarantee they could get the smell out. Bio one Was able to. They Took the smell out and were reasonably priced punctual and very friendly. I would definitely recommend Bio-one if you have any type of pet odor or any odor in general.

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.

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.

I was so pleased with this company’s quick response. I had 3 bids and this company had the best price of all 3. The projects manager was covid aware and prepared. Everything was explained in detail. I had an estimated with in hours. He worked with my deadlines. The team that arrived were professional and very friendly. They worked well together and even noticed another issue I was not aware of. And informed me of it. Great company good work ethic I highly recommend them.

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!

Recently contacted B/O regarding a potential mold issue in an out-of-area college apt. Tom was quick to provide options and remedies vs. opting for a highly expensive professional testing outfit. End result: Mold issue minimized. Healthier environment for all roommates. Savings of 1/2 the professional testing charge. The professional testing would not have SOLVED the problem. You can bet, Tom & Bio One will get the call (first) should another home or business environmental issue arise. Thanks Bio One Chester County!

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 🙏♥️
