Chula Vista Emergency Vehicle Decontamination 

My neighbor recently needed some help with a hoarding issue, so I called Bio-One on her behalf. They were super helpful and did a job no one else wanted to do. Definitely recommend.

Jason and Steve know their stuff, and they are very personable & professional. They got to the root of our mold problem, took care of it quickly and educated us throughout the process. We are glad that we used their services.

My studio was in a pretty bad state after a bad mental health situation caused it to get this bad but Jason and his crew cleaned it up so incredibly well that I won't be ashamed to have people come over finally. I'm extremely pleased with the outcome and definitely recommend them for any clean up job.

Jason was easy to communicate with, prompt and very clear on what process he would be doing in the space. Thanks Jason!

I didn't realize before meeting Jason, the importance and necessity of his service as an imperative part of a healthy and functioning society. What his business provides is the work that most people don't think about, the hard but real situations many elderly and debilitated people live in that are unsafe and unsanitary. Jason is very compassionate and takes pride in helping people improve the situation they are living in by cleaning up and helping his clients find resources to improve their wellbeing. He doesn't stop at what his service provides, but gives people options and solutions so that they can avoid another disaster. He is incredibly responsive and will do anything he can to fix the problem. Thank you Jason and Bio-One Chula Vista for your hard and important work.

Great job. Jason helped me out of a bind at the last minute and was very professional, patient and efficient in his work. I highly recommend and will use his company again in the future.

I had a situation where I needed covid clean up fast. I had called several other companies and was put on hold or they will call me back in a couple of hours. I calle Bio One and Jason answer said he would be here at 2:30pm and he showed up on time gave me a quote on the spot and took care of the job! Thank you Jason it gives me peace of mind that we are able to continue to work in a disinfectant environment!

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

An absolutely wonderful service, with easily the best value in San Diego. The speed, efficiency, and care taken is unrivaled. A company that cares, a company that's efficient. I had a problem that would have taken me months, if not years, to do on my own, and they managed to pull it off in three days. They managed to sift through things and keep a lot of things I wanted to keep, unlike many businesses that'd toss near everything. Truly delivers the help that I needed.

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.
