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!

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 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.

Tom and his team are absolutely amazing! I called at lunchtime to have my home cleaned following a COVID quarantine - they arrived the same day at 4:30! So accommodating. I would not hesitate to call Tom again in the future.

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.
