I highly recommend Kevin and the Bio-One team. Their dedication and commitment to supporting their customers is exceptional. I truly appreciated their communication and updates throughout the process. You can rest assured they will get the job done right the first time.

We found ourselves at a place in life we never dreamed we would be but with one call and one hour later Kevin arrived at our door and cleaned up the mess left behind by my brother. I won’t go into details but it was horrible. Kevin was kind, considerate and understanding of the situation and quickly got to work cleaning and sanitizing the bio waste. I anticipated paying much more for this clean up but was pleasantly surprised when I received the bill. I highly recommend Kevin at Bio-One Fremont.

Bio-One proved to be an incredible source of support and assistance for my family during a time of unexpected tragedy after the passing of my beloved grandmother. Their team exhibited immense compassion and professionalism as they handled the difficult task of cleaning the affected area with sensitivity and care. Their expertise and attention to detail brought a sense of comfort during an emotionally challenging period. Bio-One's unwavering dedication and understanding helped alleviate some of the burdens we faced, and we are forever grateful for their invaluable assistance in our time of need.

I recently hired a professional clean up service in Fremont, CA, and I am thrilled to share that they are trustworthy professionals. From the moment I contacted them, their professionalism was evident. They were prompt, reliable, and displayed a high level of expertise. I felt confident entrusting them with the task at hand, and they exceeded my expectations. I highly recommend their services for anyone seeking reliable and trustworthy professionals for their clean up needs.

It was a pleasure working with Kevin Jameson of Bio-One Fremont. A huge burden was lifted after he and Atakan sanitized and deodorized the garage and shed after rodents left a nasty mess. They did a great job of filling their trucks with items that needed to be hauled away. Kevin is very responsive to calls, texts and emails. Great job guys and thank you so much!
