decontamination and biohazard cleaning services reviews

Tom's service was invaluable to me during a sensitive situation. He was personable, efficient, flexible, professional and his advice was appreciated. Tom and his team were reliable, thorough, and overall did an outstanding job with the decluttering and cleanout of a challenging residence. I would absolutely recommend Tom and his Bio-One company.

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.

So happy we chose them to do the clean-up work at our family member's home. Tom and his crew are true professionals. Could not be more helpful, accommodating, and informative. So patient in answering our many questions and had solutions for every concern. Always punctual and responsive. Very grateful to find such amazing service at a stressful time. Beyond our expectations!!!

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.

Sue P, N/A, 12/08/2020

I needed a rapid turn-around on an apartment clean up for my Senior loved one who had an unfortunate fall into some self neglect and squalor. I conducted an internet search, and was able to reach Tom. I spoke with him in depth avout my family's needs. He was compassionate, and efficient. On the day of clean-up he and the crew were on time and eager to get to the job. Tom was honest and realistic about the job. The team were extremely patient and affectionate to the pets that were caught in the clean-up. Tom kept in touch throughout the clean-up until the end. I would refer them to anyone who finds themselves in this type of crisis needing a company that is professional, compassionate, trustworthy and efficient.

Truly Meek, N/A, 08/25/2021

We weren’t happy with the reason we needed his services (raccoon feces) , but Tom made things so much better. He answered my call promptly and was so helpful. He came at the appointed time and was incredibly efficient. There were a few hoops for him to jump through regarding our property, but he took it in stride and came out victorious! I highly recommend him! Totally thorough, accommodating and friendly.
