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!

Great customer service. They answered our call right away and were onsite the following morning. The owner was very helpful. I would highly recommended this company!

I can not give Tom and his staff enough praise. They were wonderful and professional in all ways. Lance came out to give us the estimate we needed and was curious and a pleasure to deal with. Excellent customer service. I highly recommend.

I highly recommend Tom and Bio-One. He was amazing from the first phone call. He handed a delicate situation for us and was very helpful for further recommendations. He was prompt and helpful in resolving the problems. We were in town for only a few days and he was quick to help us resolve all. He went the extra mile and did a great job! Professional, accommodating and very helpful in a stressful situation.

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.

Super friendly service, great customer service. They were even willing to help out when I wasn't able to afford service. Would highly recommend.

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 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.

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.)
