Tom Gervasio, the owner, is very professional and responded to our call quickly. He was flexible and able to work around the condo association’s restrictions for dumpsters. His crew was friendly and very helpful during the stressful situation. They were able to locate important paperwork despite the garbage, animal feces, etc. I highly recommend Bio-One.

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 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.

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!

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 sanitize 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!

What an amazing experience. A member of my family has struggled with hoarding disorder for many years. It wasn’t until I came by to visit that I found that it had progressed to the point where her house was extremely dangerous and hardly livable—bags piled to the ceiling in every room, and every desk drawer and cabinet filled to the brim. Some windows were inaccessible and had not been opened in years. I called Bio One to inquire and the owner, Tom, thoroughly answered all my questions and walked me through the process and gave me cost estimates. Over the course of a few days, I watched Tom and his very respectful cleaning team transform her house from a garbage dump into a beautiful home. Bio One literally changed our lives for the better. I highly recommend them. They’re really the absolute best!!

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.

Amazing job and staff!! They cleaned and sanitized from COVID-19 my entire apartment and also my car. Their staff are very friendly and profesional. They have all the equipment necessary, very professional!. They were very nice to my dogs, they explain me all this products won’t harm them and they were very thoughtful on making sure our dogs would be safe the entire process. Definitely would hire their services again without a doubt!!

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..
