    "Where do I even begin, I called this company and got in contact with Steven, I had no idea what we really needed for my client but I knew I needed help! Steven spoke with me and I knew I found the place to handle the job we had. I booked the following day, and within a week the project began. The team was exceptional. Everyone that entered my clients home was top notch, kind, educated in the field, and ready to make a difference just as much as I was. I loved this company so much, we booked them already for another job! I highly recommend if you or a loved one may have a little to much trash and are in over your head with needing a cleaning service who literally get the job done RIGHT! I cannot even thank the team enough for making the huge difference in the home within a single day! Thanks GUYS!!!!:] IF 10 stars was an option I 'd give them a 10 out of 10!!!"

    I was in some deep, deep cat urine due to some interpersonal (interfelineal?) issues among my three cats. Not only have I come back to an immaculate, odor-free home, but the team was proactively communicative, professional, and went above and beyond to take care of us. How above and beyond? When they arrived promptly at the assigned time, I had only managed to get two of my three monsters into their carriers for transport to the cat hotel. Number three — the largest and least intelligent of my brood — had escaped me for the better part of an hour. Sweating and frustrated, I let the team from Bio-One in with my apologies. That’s when all four of them got right on the case and helped me get the fur jerk into his bag within minutes. Five star service all around!

    The phone contact person was very polite, professional, non-judgmental and took time to answer all of our questions: we never felt rushed in this process. The team that cleared, cleaned and disinfected the hoarder house was equally professional, non-judgmental, thorough, cheerful, and very respectful of the home owner and his house. We have a very special thanks to the crew that took on a huge difficult job and gave us an excellent outcome.

    "Steven and his team did an amazing job from beginning to end cleaning our basement and crawlspace from Rat droppings and urine. From his initial quick response and next day assessment, he was flexible and understanding during our conversations, and got his team scheduled in a very timely manner. They did an amazing job cleaning the basement and crawlspace and disposing of everything safely. Would hire Bio-One again in a heartbeat!"

    Bio One East Bay specializes in cleaning hoarder houses, crime and trauma scenes, mold, urine and feces, meth, Covid-19 etc. Though they are located in Oakland CA they travel throughout the entire Bay area and arrived on time each day. They were like angels for us. We needed extensive cleaning of a hoarder's house that included bio-hazard elements. From the on-site estimate to the final day of cleaning, the team was professional, knowledgeable, efficient, flexible and discreet. They executed a thorough cleaning and disposed of some contaminated furniture for us. Their fee was reasonable and their kindness was deeply appreciated. I recommend them without hesitation.
