"I am so grateful for Bio-One. I called and spoke with the owner, and he gave me a next day appointment. The price was competitive. I had an infestation of mice, and they were located primarily in the pantry. He reassured me that this was a job his business could handle and walk me through the process so I would know what to expect. On the day of the appointment he sent me a reminder Text and another text to let me know when he was in route. He and his nephew, Mr. Atakan Efe, arrived 10 minutes early to the job. I showed them the pantry and they got to work. They went above and beyond not only cleaning/guttering/disinfecting the pantry, but also cleaned underneath the stove, refrigerator, and the ENTIRE floor. They also plugged the holes where the mice were coming out of. They gave me advice on what to do next. I am above and beyond grateful for them. I feel like I can use my kitchen again. I really appreciate this business for their professionalism, honesty, and hard work."

It was a pleasure working with the owner 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. He is very responsive to calls, texts and emails. Great job guys and thank you so much!

I know Atakan personally and he is extremely hardworking and diligent in his work. He never leaves a job until it is 100% completed and puts passion into his work.

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.

    We found ourselves at a place in life we never dreamed we would be but with one call and one hour later he arrived at our door and cleaned up the mess left behind by my brother. I won’t go into details but it was horrible. He 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 him at Bio-One Fremont.

    I had to stop around the area before heading up to Mill Valley, and I can say with absolute certainty that these people know what they're doing. Super punctual and I barely had to lift a finger. My stop was short and sweet. Absolute pros! Whoever I talked to was super nice. I would definitely recommend them and when I am in the area that's who I will use all the time. Outstanding.
