About Us

“The owner's name is Jason. He is extremely responsive and understanding. My situation was very stressful and he took the time to listen and provide a solution to help me move forward. I strongly recommend working with him and his company.”

“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.”

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

“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.”

“When the worst things happen, it's good to know that there are still people out there to help. Thank you so much Bio-One for your professionalism and your thorough work.”

“Bio-One Chula Vista did an awesome job cleaning the house! They did a more thorough job and at a better price than what other companies offered. They went above and beyond. The crew got floors, counters and showers clean that I thought were impossibly stained. They sorted and retrieved precious family heirlooms and valuable items. The guys even did an extra good job detail cleaning my aunt’s room because she has allergies and asthma. Jason honored the original estimate, even though it was more work than originally thought and stayed late to get the job done. He communicated and documented throughout the job. I highly recommend Bio-One Chula Vista!”

“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.”

“Recently I had a need to disinfect a small rental property. Jason was on site within one hour of my call and was extremely professional providing the service. I feel very comfortable and confident with the result of his work.”

“Jason Madsen was extremely helpful and provided excellent quality work. He was able to address all questions and concerns that I had.”
