Wow! What a difference! My home is actually a home again! Jason and his team were very kind and respectful, getting things organized and accessible. I so appreciate their hard work and highly recommend them.

In the most stressful time possible, when the unexpected and shocking events of life happens, these are THE best professionals to step in and help. Jason provides the most timely comprehensive expertise how to best accomplish the specific needs of a situation. With a clear understanding of a family's objective on what needs to be addressed, his excellent communication and insight truly help to lessen the weight of accomplishing what seems overwhelming. We are so very grateful for his compassionate understanding of the situation and an amazing sanitizing job. What a relief to have found superb authorities cleanup and biohazard. Thank you so very very much!!

I hired Bio-One for a biohazard/hoarder house clean up that was unlivable. It was wall to wall, floor to ceiling clutter, beer bottles, dog waste, food waste and trash. From the initial walkthrough, their professionalism and expertise was amazing. They meticulously sorted through the clutter, ensuring that any valuables or personal items were set aside safely. Their attention to detail was incredible, and they handled the hazardous materials with care. What truly impressed me was their empathy and respect throughout the process. They understood the sensitive nature of the situation and approached it with compassion and understanding, making a challenging experience more manageable. Assuring me, I was not the only one that has gone through this. Which made me feel so comfortable. They also kept me posted throughout the clean up and reached out when they had any questions. The transformation of the house was nothing short of miraculous. I cannot thank them enough for their exceptional service. If you are ever in need of a biohazard clean up or a highly complex situation like a hoarder house, I highly recommend Bio-One of Chula Vista.

I started working for BIO-ONE, under the guidance of Jason Madsen in January of this year. Being an Environmental Engineer, relocated from Northern California and former US Army Ranger I have been absolutely impressed with the level of professionalism and integrity that he has displayed. B.D.

I can’t say enough good things about my experience with Jason from Bio One... But one thing that really stood out in this whole hoarding/decluttering process (which was so hard & emotional for me) is that he made me feel comfortable not only by his professionalism but by his kindness & understanding as well. I thank you so much Jason! Sincerely, Justyne Meza

Thank you Jason for arriving to check my problem less than 2 hours of my call. Jason checked all around the affected area and gave me excellent advice on how to handle it. Jason is efficient and his advice was effective and useful. I am very happy I called Bio-One and will call again if needed.

Jason and he's crew did an excellent job, I strongly recommend him. I am very happy with the result.

I needed my house Covid sanitized before i can put it in the market. Working with Jason was a breeze! I needed a weekend appointment and he was very accommodating. Scheduling was a breeze and he showed up early. . Very professional! 👍👍

BioOne is fantastic, and they arrive in an hour!

Amazing service, and on time, thanks! If you need a place disinfected, call Jason!
