When I called they gave a prompt response and set up an appointment for 2 days away and that was excellent. We settled on a date for the service to begin and they were prompt and on time. They're demeanor was excellent and I enjoyed the manner in which they performed their services. They were completely professional and respected my possessions and myself. If asked I would recommend them to anyone that required this kind of service.

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.

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 🙏♥️

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!

Bio-One Chester County is the best company to hire for cleaning up messes that are beyond your capability to handle. Tom estimated the cost, materials and number of days to complete the project. Despite the need to scale the job up during execution, the job was completed on time and on budget. Tom and his crew are great! They are punctual, professional, talented, experienced, humorous, and honest. When unanticipated problems arose during execution, Tom called immediately to discuss resolution options and provided guidance to lead me gently to what I believe to be the best option. You can't go wrong by hiring Bio-One Chester County

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.
