Thank you for trusting us.
We're ready to serve you!

If I could give them 10 stars, I would. I can’t say enough about the efficiency and professionalism of everyone from the owner to the foreman to the work crew. Very respectful on every level and finished the job ahead of schedule. Highly recommended.

5 Stars are NOT ENOUGH!! Rarely have I had service in any capacity like the EXCEPTIONAL SERVICE GIVEN by the Entire Team at Bio 1 of Chester County!!! Tom picked up the phone at 9:45 at night after my spending all day with another "" Cash only"" vendor . He spoke in clear Terms about the Bio Hazzard job & the insurance process. He made all this happen in Record time and did all the Insurance paperwork too!! Tom also recommended another vendor for a different service, and they were also stellar!! I JUST HIRED Bio 1 of Chester County AGAIN this week for another clean up, and my neighbor Vicky texted me to remark on what a fast and efficient job they did. I am placing them in my phone for future work, they are worth their weight in PURE GOLD!!! There are NOT alot of people in any line of work that could match Bio 1 of Chester County!!!

Definitely recommend! Timely communication and EXCELLENT customer service! Bio-One cares and they aim to achieve the right outcome for their clients! Thank you!

SUPER SUPER EASY TO WORK WITH, VERY FRIENDLY.

Tom was quick to respond and give me an estimate for cleaning out my cousin's home. Me and my cousin, who is ill, differed on what to toss/what to keep. Tom was great at stepping back while my cousin and I "negotiated", and stepping in when we needed clarification. He's understanding, experienced, knowledgeable. He and his crew were quick, personable and flexible!!!! If you're like me --embarrased about having someone see a "beyond messy" house - don't worry. Tom knows instinctively how to put people at ease. So quit procrastinating and give him a call!

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.

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 🙏♥️

Best money I ever spent. They made me feel so comfortable with what I needed done. They were so sensitive to me and my needs. They did the job in one day, and I will be grateful forever.

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.

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!!
